Employee roles in sustainability transformation processes: A move away from expertise and towards experience-driven sustainability management
Authors: Süßbauer Elisabeth , Maas-Deipenbrock Rina Marie , Friedrich Silke , Kreß-Ludwig Michael , Langen Nina , Muster Viola
Published: August 2019

Corporate sustainability management usually relies on innovation experts ‐ that is, it relies on top-down and staff-unit approaches. Seeking out the involvement of employees from all company departments can substantially contribute to corporate greening. “Ordinary”
employees are not trained as sustainability experts, yet it is precisely their experience within their own field and within the organisation that can give rise to knowledge that is essential for transforming the economy towards sustainability. Hence, employees need to be empowered by appropriate
structures and organisational culture. Transferring practical experience to expertise can prove very helpful in assisting and stimulating sustainability transformations in various business fields.Although ordinary employees are typically regarded as an important stakeholder group for enhancing
corporate sustainability, they are seldom seriously addressed in business or research practice. To learn from the practical experience of what takes place at workplaces, we analysed four transdisciplinary research projects all aimed at initiating, accompanying and analysing processes of sustainability
transformation within companies, but which focused on different sectors and organisational contexts. Based on the assumption that ordinary employees can hold three different roles in processes of sustainability transformations (implementers, ambassadors and recipients of corporate sustainability
practices), we compared the findings from practices of employee involvement within the four projects. Based on these findings, we examined the implications for companies and highlighted future research needs.

Authors: Basiru Afisu , Akorede Ganiu Jimoh , Soetan Kehinde , Olayemi Funsho O.
Published: August 2019

Background

Numerous uses of Waltheria indica plant such as antitrypanosomal, antibacterial and antimalarial effects have been reported. It has however been reported that most plants with antibacterial and antiprotozoal effects have adverse effect on male reproduction. Hence, we evaluated the effect of Waltheria indica root on male reproductive parameters.

Methods

Twenty adult male Wistar rats were randomly divided into four groups (n=5); A–D. Group A served as control group while groups B, C and D were administered with 200, 400 and 800 mg/Kg body weight of crude ethanolic extract of Waltheria indica root. After 28 days of administration, the rats were sacrificed and sperm parameters, sperm morphology, serum reproductive hormones and lipids were determined.

Results

There was a significant reduction in sperm count and motility as well as significant increase in percentage abnormal sperm cell (p<0.001) at the 400 and 800 mg/kg BW. The serum levels of testosterone was also significantly reduced while total cholesterol increased significantly (p<0.05) at the highest dose.

Conclusion

Waltheria indica root has adverse effect on male reproduction through reduction in sperm parameters and male reproductive hormones.
Comparing insults across languages in films: Dubbing as cross-cultural mediation
Authors: Pavesi Maria , Formentelli Maicol
Published: August 2019

Insults are prototypical means to express impoliteness in social interactions. In film they are prime ways of staging conflict or jocular abuse, reflecting everyday communicative practices while contributing to the emotionality of dialogue, characterisation and plot advancement. Both original and dubbed films offer a privileged perspective to investigate the codification of impoliteness within and across linguacultures. In this contribution, we hypothesise that cross-cultural mediation in dubbing arises from hybridisation, a product of the contact between source and target language. Drawing on a parallel and comparable corpus of original and dubbed films, the study focuses on two major categories of insults and explores contrastively their overall frequency, the distinction between genuine and mock impoliteness and the structural complexity of forms. A degree of comparability is observed across Anglophone, Italian and dubbed Italian films, although distinctive trends also emerge from the corpus analysis. If Italian films globally make more frequent use of insults, Anglophone films stand out for their greater reliance on mock impoliteness and greater elaboration of forms. Dubbed films tend to position midway, reproducing source language patterns, while also partaking distinguishing lexico-grammatical traits of the target language. The results substantiate the function dubbing serves in cross-cultural mediation by activating an array of frames of reference that allow the new receiving audiences to experience foreign communication practices from their native language perspective.
Inscribing indigeneity: Ethnolinguistic authority in the linguistic landscape of Amazonian Ecuador
Authors: Wroblewski Michael
Published: August 2019

This article takes a linguistic anthropological approach to analyzing multilingualism in the linguistic landscape of the Amazonian city of Tena, Ecuador, a key locus of indigenous Kichwa language revitalization, identity formation, and politics. Following recent scholarly reconsiderations of multilingual linguistic landscapes as sites of ideological contestation and performative display, I seek to expand on the foundational concept of ethnolinguistic vitality. Building on an analysis of shifting materiality and semiotics of bilingual Kichwa-Spanish hospital signs, I argue for the use of longitudinal and deep ethnographic study of public sign-making in progress to identify oppositional struggles over ethnolinguistic authority, or control of authorship in displays of ethnolinguistic presence. In Tena, Kichwa-language signage represents a new venue for the decolonization of politics, the performance of indigeneity, and the centralization of state power, which are expressed through competing visions by agents with distinct ideological orientations toward language. I submit ethnolinguistic authority as a critical concern for the ethnographic study of public inscriptions of minority languages, which reflect contrasting ideologies of language, notions of group identity, and claims to representational sovereignty.
The relationship between fear generalization and pain modulation: an investigation in healthy participants
Authors: Vandael Kristof , Meulders Michel , Vanden Boer Celine , Meulders Ann
Published: August 2019

Background and aims

Pain-related fear and its subsequent generalization is key to the development and maintenance of chronic pain disability. Research has shown that pain-related fear acquired through classical conditioning generalizes following a gradient, that is, novel movements that are proprioceptively similar to the original pain-associated movement elicit more fear. Studies suggest that classical conditioning can also modulate pain and conditioned fear seems to mediate this effect. However, it remains uninvestigated whether this is also the case for generalized fear.

Methods

In a voluntary joystick movement paradigm, one movement (conditioned stimulus; CS+) was followed by pain (pain-US), and another was not (CS−). Generalization to five novel movements (generalization stimuli; GSs) with varying levels of similarity to the CSs was tested when paired with an at-pain-threshold intensity stimulus (threshold-USs). We collected self-reported fear and pain, as well as eyeblink startle responses as an additional index of conditioned fear.

Results

Results showed a fear generalization gradient in the ratings, but not in the startle measures. The data did not support the idea that fear generalization mediates spreading of pain.

Conclusions

Despite the lack of effects in the current study, this is a promising novel approach to investigate pain modulation in the context of chronic pain.

Implications

This study replicates the finding that pain-related fear spreads selectively towards movements that are proprioceptively more similar to the original pain-eliciting movement. Although results did not support the idea that such generalized fear mediates spreading of pain, the study provides a promising approach to investigate pain modulation by pain-associated movements.

Synaptonemal Complex Central Region Proteins Promote Localization of Pro-crossover Factors to Recombination Events DuringCaenorhabditis elegansMeiosis
Authors: Cahoon Cori K , Helm Jacquellyn M , Libuda Diana E
Published: August 2019

Errors during meiosis are the leading cause of birth defects and miscarriages in humans. Thus, the coordinated control of meiotic events is critical for the faithful inheritance of the genome with each generation...

Crossovers (COs) between homologous chromosomes are critical for meiotic chromosome segregation and form in the context of the synaptonemal complex (SC), a meiosis-specific structure that assembles between aligned homologs. During Caenorhabditis elegans meiosis, central region components of the SC (SYP proteins) are essential to repair double-strand DNA breaks (DSBs) as COs. Here, we investigate the relationships between the SYP proteins and conserved pro-CO factors by examining the immunolocalization of these proteins in meiotic mutants where SYP proteins are absent, reduced, or mislocalized. Although COs do not form in syp null mutants, pro-CO factors COSA-1, MSH-5, and ZHP-3 nevertheless colocalize at DSB-dependent sites during late prophase, reflecting an inherent affinity of these factors for DSB repair sites. In contrast, in mutants where SYP proteins are present but form aggregates or display abnormal synapsis, pro-CO factors consistently track with SYP-1 localization. Further, pro-CO factors usually localize to a single site per SYP-1 structure, even in SYP aggregates or in mutants where the SC forms between sister chromatids, suggesting that CO regulation occurs within these aberrant SC structures. Moreover, we find that the meiotic cohesin REC-8 is required to ensure that SC formation occurs between homologs and not sister chromatids. Taken together, our findings support a model in which SYP proteins promote CO formation by promoting the localization of pro-CO factors to recombination events within an SC compartment, thereby ensuring that pro-CO factors identify a recombination event within an SC structure and that CO maturation occurs only between properly aligned homologous chromosomes.

Authors: Ozan PhD Gunce , Sar Sancakli DDS Hande , Tiryaki PhD Murat , Bayrak PhD Isil
Published: August 2019

Aim: Sufficient polymerization remains as crucial for composites to prevent discoloration. Both LEDs and halogen units are used for polymerization and different curing modes are improved to overcome inadequate polymerization. This in vitro study investigated staining susceptibility of a nano-hybrid resin composite light-cured in different modes and immersed in different staining media. Methods: Disc-shaped specimens were prepared from nano-hybrid resin composite (Filtek Z550) and light-cured according to following modes: Halojen (GI), LED standard (GII), LED pulse (GIII) or LED ramp (GIV). Half of the specimens of each group (n=7)  were stored in one of the staining media (red wine or coffee) for 10 min/day during experimental period. Measurements were performed using spectrophotometer according to CIEL*a*b system at baseline and on 7, 28 and 56 days. Colour differences (∆E) between groups were submitted to statistical analysis. Results: Regarding 7-day evaluation, colour change values of specimens immersed in coffee revealed no remarkable difference among curing modes (p>0.05); whereas specimens in GIV were significantly less stained compared to specimens in GII and GIII when immersed in red wine. Regarding 56-days of evaluation, specimens of GIV showed statistically significant colour change in red wine compared to other groups. However specimens in GI revealed the least staining after 56-days of coffee immersion, and this result was statistically different from LED groups. Conclusion: This study suggest that light-curing mode influences the staining susceptibility of the tested composite. Composites polymerized with halogen unit showed lower staining than all LED modes. Despite novel light sources, halogen units may still used reliably at clinics.
TERRAFORMING MARS IS NOT OUT OF THE QUESTION YET – AND MICROSCOPIC ALGAE COULD HELP
Authors: Vasileva Iv. , Ivanova A. , Alexandrov S.
Published: August 2019

Recently some researchers have gathered around the claim that the likelihood for terraformation of Mars is slim, either because human technology is not up to the task, or the planet does not posses all the necessary resources to allow the process to be completed successfully. This manuscript takes a closer look both at the latest and previous scientific articles, optimistic and skeptical, while trying to reassess the terraforming potential of the planet. To achieve that, we summarized results from different experiments conducted with algae and higher plants. According to our reevaluation, it is concluded that even if the skeptical papers are right, and the others are overly optimistic, partial terraformation of Mars is still possible. It is also suggested that terraforming the planet partially could be a good option if we want to protect the local organisms, assuming that they exist.

Published: August 2019

Introduction : the problems of sports selection and selection of prospective children in martial arts schools are quite relevant in the sports practice. It was revealed the use of various selection techniques in the practice of martial arts. There is no unified methodological system for selection in martial arts schools. The purpose of the study : to determine the dependence of the dynamics of sports results of elite athletes on the procedure of sports selection (for example, the Greco-Roman wrestling). Material and methods : elite Greco-Roman wrestlers (n = 114) took part in the research. Age of athletes: 25-45 years. Qualification: International masters of sport (n = 8), masters of sport (n = 49), candidates in masters of sport (n = 57). Athletes filled out a diagnostic card with data on the procedure of sports selection. It was indicated the dynamics of competitive results during the sports career. Indicators of performance and stability of athletes were calculated applying the mathematical statistics methods ( ). The reliability of the results was determined by Student's t-test. Results : Data analysis showed that a significant part of athletes did not pass the selection procedure (n = 23). Many athletes passed only a partial selection procedure (n = 39). Some athletes did not pass the selection procedure. These athletes are not inferior in terms of stability to athletes who passed the selection at the 1st and 2nd levels of competitive results. In subsequent competitions, these athletes demonstrated the reliable (P <0.05) decrease in indicators of stability in comparison with other athletes. It was revealed a significant (P <0.05) advantage in indicators of stability among athletes who passed a partial selection procedure at the 4th level of competitive results. Conclusions : It was found the dependence of stability indicators at high levels of competitive results on the selection procedure of athletes. The athletes who passed the selection procedure demonstrate higher stability at high levels of competitive results. It was revealed a formal attitude to the selection procedure in some coaches and specialists. The trainers do not pay due attention to the indicators of maintaining body balance and coordination abilities during the selection of candidates. It has been revealed that the motor tests applied in the selection procedure do not allow an objective assessment of the potential of athletes' competitive achievements.

Authors: Yamaner F.
Published: August 2019

Purpose: Weight control and weight loss during the periods of wrestling competitions are attached great importance -in order to be successful in wrestling. Leptin hormone level is known to play an important role in the control of body weight. For this reason, the purpose of this study was to investigate the effect of substantial weight loss on serum leptin levels of women wrestlers during competition periods. Material and Methods: Twenty-five women wrestlers who trained for 2015 European Championship from Turkish National Wrestling Team and 26 sedentary women were recruited voluntarily for this study. Serum leptin levels of wrestlers in the experimental group and sedentary women in the control group were measured after overnight fasting before and after 21 days training camp of 2015 European Championship. Results. Statistically significant difference was found in the direction of decrease in body weight, body mass index (BMI), glucose, insulin, cholesterol, triglyceride, LD, VLDL and leptin parameters and increase in HDL parameters before and after training camp in the experimental group ( p < .05 ). There was a statistically significant difference in leptin levels between the control group and women wrestlers ( p < .05 ). There was also a statistically significant difference in leptin levels of wrestlers before and after training camp ( p < .05 ). Conclusion. As a result, the data obtained in the study indicate that intense wrestling trainings in camping period brought about weight loss and decreased leptin levels.

Barriers to the Effective Regulation of the Building Construction Industry: An Empirical Analysis
Authors: Omollo W. O.
Published: August 2019

This study investigates key barriers to the effective regulation of the building construction industry in Kenya, a case study of Kisii Town. It was guided by the Public Interest Theory of Regulation, which provided the underpinning elucidating why the building construction industry in Kenya needs regulation. The target population comprised 84 registered building contractors with a sample size of 66 selected using simple random sampling by application of random number table. As regards limitation, the study does not measure the extent of quality assurance within the construction industry, but rather delve on the key factors impeding its effective regulation. The research findings show that ineffective regulation of the construction industry in Kisii Town was prompted by the joint activities of building development contractors and limitations of the National Construction Authority (NCA) (the regulator). Regarding the activities of building contractors, identified barriers included failure to refer to key legislation that regulates the construction industry, failure to obtain statutory approvals of building development, and laxity to invite supervision of ongoing projects by planning authorities. Conversely, factors elucidating why NCA was not successfully regulating the construction industry included inadequate multi-sectoral coordination, inadequate surveillance, and limited sensitization of key stakeholders. Drawing from these findings, the study recommends regular monitoring and enhanced enforcement that would promote compliance and sensitization of contractors with applicable standards and regular inspections of ongoing projects. Also, establishing a coordinating committee to harmonize institutions that deal with development control.

A semiótica do compartilhamento de conhecimento tácito: um estudo sob a perspectiva do interacionismo simbólico
Authors: MIGUEL LILIAN APARECIDA PASQUINI , POPADIUK SILVIO
Published: August 2019

Abstract This article proposes an integrated theoretical model, combining Polanyi and Peirce constructs - tacit knowledge and semiotics, respectively - under the symbolic interactionist perspective. It aims to understand how signs are manifested as mediators in the tacit knowledge sharing process among members of a cooperative organization. It is based on: a theoretical articulation of the principles of tacit knowledge, which defends the ineffability of this kind of knowledge; semiotic theory, in which signs are a representation of “something for someone” and imply that everything in the world is a sign; and the symbolic interactionist view. This theoretical integration presents a significant theoretical contribution because it proposes a process of semiotic perception to tacit knowledge sharing. This perspective suggests that tacit knowledge sharing occurs through symbolic interaction, mediated by semiotics; this innovative model depends both on internal and external conditions, albeit involving aspects outside organizational control.

Os “pontos cegos” das teorias organizacionais segundo Guerreiro Ramos
Authors: WEBERING SUSANA IGLESIAS
Published: August 2019

Resumo Este artigo se baseia em dois livros de Alberto Guerreiro Ramos, Administração e contexto brasileiro e A nova ciência das organizações: uma reconceituação da riqueza das nações, e tem por objetivo apresentar os principais aspectos das teorias organizacionais analisados pelo autor, que os denomina “pontos cegos”. São quatro os pontos cruciais que as teorias organizacionais não suprem e, ao se desenvolverem, absorveram conceitos que foram transformados: a) a noção de racionalidade, que domina não só os Estudos Organizacionais, como também a economia, a ciência política e as ciências sociais; a b) não distinção entre significado substantivo e significado formal de organização; c) as teorias organizacionais não têm clara compreensão do papel das interações simbólicas; e, por último, d) as teorias organizacionais se apoiam somente em uma visão mecanomórfica do homem. Os pontos, que são aprofundados ao longo das duas obras, aparecem enumerados em um capítulo específico de A nova ciência das organizações. A impressão é de que o próprio Guerreiro Ramos tenha sentido essa necessidade, como uma breve recapitulação, antes de propor seu modelo multidimensional de sociedade (que não é abordado neste artigo). Isso se dá pela amplitude e profundidade da obra de Guerreiro Ramos. Exemplo disso são as possíveis agendas para seu estudo já elaboradas por diversos outros autores. Conclui-se que o pensamento de Guerreiro Ramos se mantém atual, suas críticas e preocupações são pertinentes e mostram-se fundamentais para os que pretendem desenvolver estudos críticos na área de organizações, em seu ensino e no desenvolvimento de outras possibilidades de gestão.

Resumo Este artigo analisa a relação entre investimentos em educação e os indicadores que acompanham o desenvolvimento da qualidade de ensino, especificamente com o Índice de Desenvolvimento da Educação Básica (Ideb). A metodologia adotada tem caráter quantitativo e recorre à investigação bibliográfica e documental. Foram consultadas fontes estatísticas públicas, disponibilizadas por órgãos como o Instituto Brasileiro de Geografia e Estatística (IBGE) e o Instituto Nacional de Estudos e Pesquisas Educacionais Anísio Teixeira (Inep), que possibilitaram identificar o desempenho alcançado no Ideb para correlacioná-los ao volume de recursos destinados às escolas em caráter suplementar, por meio do Programa Dinheiro Direto na Escola (PDDE). Para tanto, utilizaram-se ferramentas estatísticas de correlação linear de Pearson e diagrama de dispersão. Como resultado constatou-se baixa relação entre o orçamento e o resultado no Ideb. Houve situações nas quais as instituições tinham à disposição valores comparativamente altos, mas obtiveram desempenho baixo, ao passo que escolas que não dispunham de repasses suplementares consideráveis atingiram e até superaram as metas previamente estabelecidas. Isso evidencia que a correta aplicação dos recursos disponíveis é determinante na gestão escolar.
Strategic circumvention of regulations: the judicialization of the Brazilian private health system

Abstract The article aims to advance the understanding of the successive circumvention of regulations by organizations, to determine whether it is possible to characterize them as purposeful actions, while the institutional literature analyzes decoupling and circumvention as sporadic activities. It analyzes the responses adopted by health plan companies to favor their interests, responses that often fail to comply with the rules of the institutional context, and which boosted the phenomenon known as ‘judicialization’. The study analyzed 158 lawsuits collected from the electronic archives of the Court of Justice of São Paulo, where beneficiaries sue health plan companies because of treatment coverage denial. Using correspondence and thematic analysis, some associations between denials and allegations showed to be significant, suggesting companies’ strategic patterns. It was possible to identify different strategic practices adopted by companies to avoid complying with institutional guidelines, and to observe that certain regulatory features can contribute to non-compliance strategies. The article contributes to the institutional literature by identifying organizational practices meant to successively circumvent and confront institutional prescriptions, indicating that health plan companies apparently design specific strategies to respond to beneficiaries’ demands.

Authors: PILON Juliano , COSTA Ana Rosa , CORRER-SOBRINHO Lourenço , VEDOVELLO FILHO Mário , VALDRIGHI Heloísa Cristina
Published: August 2019

Abstract Introduction The orthodontic movement is directly influenced by the ability of orthodontic wires to slide through brackets and tubes. Therefore, the main concern during orthodontic movement corresponds to the frictional forces generated at the bracket-orthodontic wire interface. Objective This study aimed to evaluate the frictional resistance of esthetic orthodontic wires. Material and method Fifty test brackets were obtained and divided into five groups (n = 10) based on the type of rectangular orthodontic wire, as follows: conventional metallic wire (Morelli, Brazil) (G1, control group) and esthetic wires (G2, Ortho Organizer; G3, Tecnident; G4, Trianeiro; and G5, TP Orthodontics). The following materials and conditions were used: 0.019 x 0.025-inch wires, ceramic brackets with edgewise prescription, torque and/or angulation of 0°, and 0.022 x 0.028-inch slots. The specimens were tested for their tensile strength using an Instron universal test machine at a speed of 1.0 mm / min and a load cell of 500N. The tensile strength data were analyzed by one-way analysis of variance (ANOVA) followed by Tukey’s post-hoc test, with a 5% significance level. Result The frictional resistance (N) of the metallic orthodontic wire (8.07 ± 0.43) was significantly higher than that of the esthetic wires: Ortho Organizer (4.01 ± 0.25), Tecnident (3.87 ± 0.31), Trianeiro (4.47 ± 0.26) and TP Orthodontics (4.49 ± 0.30) (p <0.05), with no significant difference between them (p> 0.05). Conclusion To conclude, the esthetic orthodontic wires tested herein showed less frictional resistance as compared to the conventional metallic wire.

Abstract Introduction Antimicrobial sutures are a therapeutic alternative for the control of oral infections. Objective Incorporate Chlorhexidine (CHX) and Cinnamaldehyde (CN) in sutures and evaluate the anti-Candida effect, release of antimicrobials and mechanical properties. Material and method Silk (S) and Polyglactin 910 (P) sutures were aseptically sectioned (20 mm) and immersed for incorporation in 0.12% CHX, 0.4% CN and 0.9% saline solutions under stirring for 60 minutes (n = 10 / group). Suspensions of 500 μL of Candida albicans (ATCC 90028/ 1 × 106 CFU/mL) were used to evaluate fungal adhesion after the 48 h period at 37°C. The release of CLX and CN were evaluated at 0, 24 and 48 hours (n=3/group) by UV-VIS spectrophotometer (275 nm). The tensile strength and displacement (n=5/group) were evaluated after incorporation (30 mm/min, 50N). Data were analyzed by Anova and Tukey (α = 5%). Result No anti-Candida effect was observed on S and P sutures incorporated with CLX and CN (p>0.05). However, progressive release was verified up to 48 after treatment with CLX (S = 0.075 / P = 0.073 μg/mL) and CN (S = 35.33 /P= 5.72 μg/mL). There was a decrease in tensile strength in S (CLX = 9.9 / CN = 9.9 N) and P (CLX = 14.4 / CN = 15.5 N) (p<0.05). No differences were observed for the displacement for S (CLX = 19.3 / CN=20.7 mm) and P (CLX = 16.2 / CN=15.8 mm) (p>0.05). Conclusion The incorporation of CLX and CN did not have a positive effect on the biological and mechanical properties of the sutures evaluated.

Abstract The aim of this cross-sectional study was to estimate the prevalence of self-reportedhypertension and diabetes among elderly users of primary healthcare facilities in Ribeirão Preto, Brazil, and to investigate the association between these chronic conditions and physical activity and the degree of independence on the performance of activities of daily living. The study included 357 subjects aged 60 years or older. The classification of physical activity was based on the International Physical Activity Questionnaire (IPAQ) and the Pfeffer FunctionalActivities Questionnaire (PFAQ) was applied to assess activities of daily living. Prevalence of diabetes was associated with the level of physical activity, the self-perception of health and the degree of independence on the performance of activities of daily living. No significant associations were found between the prevalence of hypertension and these variables. These findings reinforce the relevance of continuous strategies of management of diabetes in the primary healthcare facilities based on the promotion of physical and occupational activities.

Abstract This study aimed to examine the effects of Simple Reaction Time (SRT), MaximalOxygen Uptake ( V ? V ? O2max) and Maximal Anaerobic Power (Pmax) on the performance of category A recreational adult orienteers of both sexes. Sixteen subjects (8 men and 8 women; age: 30 ± 4 and 27 ± 5 years; body mass 78.8 ± 5.9 and 69.2 ± 10.4 kg; SRT: 1.391 ± 0.19 and 1.317 ± 0.25 ms; V ? V ? O2max: 67.4 ± 3.22 and 48.5 ± 8.28 ml.kg-1.min-1; Pmax: 675.0 ± 149.6 and 458.4 ± 88.62 W), were submitted to three evaluation sessions: sample characterization (1st session); SRT - Reaction Time Task v.2.0, V ? V ? O2max, and Pmax - Running Anaerobic Sprint Test (2nd session); official Orienteering test (3rd session). Results of comparison (Student’s T-test) and relation (Pearson Product-Moment Correlation and Multiple Linear Regression) tests showed significant relationships between independent variables and performance. Pmax presented strong predictive power in the male group (41%), followed by SRT (32%) and V ? V ? O2max (27%). In the female group, SRT was the most predictive variable (54%), followed by V ? V ? O2max (32%) and Pmax (12%). These findings indicated that SRT, V ? V ? O2max, and Pmax are variables predictive of performance in recreational category A orienteers. Specifically in recreational orienteers with high cardiorespiratory capacities, Pmax seems to be the mainpredictor variable. Conversely, SRT becomes the variable with the greatest predictive power.
