title: ELECTROMYOGRAPIC ACTIVITY OF THE ABDOMINAL AND PARAVERTEBRAL MUSCLES DURING COFFEE HARVESTING

description: ABSTRACT Introduction The rural worker involved in the coffee harvest is an important person for the economy of the many countries. However, scientific studies on the health of this worker are rare. Objective To analyze the lumbar paravertebral musculature and abdominal rectus of rural workers during coffee harvesting with the manual machines with different footrest bases (inclined, declined and horizontal), by means of electromyography. Methods Eight male rural workers from the region of Muzambinho participated in the study. All procedures and electromyographic routines were applied according to the SENIAN protocol. The workers made the usual coffee harvesting movements, using the manual machine for one minute. The data are expressed as means and standard deviations. The RMS (root mean square) signal and the median frequency (FM) were also analyzed. Results It was observed that the type of footrest base did not influence the electromyographic activity RMS or the FM, but we found that the paravertebral muscles have greater electromyographic activation when compared to the abdominal muscles, regardless of the type of footrest base. Conclusion For the task performed, the paravertebral muscles present greater electromyographic activation compared to the abdominal rectus. Level of Evidence III; Diagnostic studies - Investigating a diagnostic test.

title: PHYSICAL DEMAND IN SOCCER SMALL-SIDED GAMES: INFLUENCE OF TEAM COMPOSITION

description: ABSTRACT Introduction Small-sided games (SSG) are used as training tools for physical conditioning in soccer. To date, however, it is unknown whether team composition affects athletes’ physical performance. Specifically, based on the differences presented by players of different positions, it is expected that the use of positional status as a criterion for team composition will affect players’ physical performance. Objective To compare the physical demands of SSG in teams composed of young soccer players in the same position or different positions. Methods 12 U-15 soccer players participated in the study. The athletes performed 3v3 SSGs under two conditions: teams in which the athletes played in the same position (i.e. three defenders), and teams in which the players took up different positions (i.e. defender, midfielder and attacker). Data were obtained on total distance traveled, distance in speed zones, and accelerations, using GPS devices. The data were analyzed using the paired t-test, comparing the two experimental conditions. Results There was higher physical demand among defenders and midfielders when the SSG was performed with athletes playing in the same position, in terms of distances covered in different speed zones. However, there were no differences in relation to acceleration actions. Conclusion Team composition affects the physical performance of soccer athletes during 3v3 SSG. Level of evidence IV; Case series.

title: EVALUATION OF THE ORAL HEALTH CONDITIONS OF VOLLEYBALL ATHLETES

description: ABSTRACT Introduction Dental care can improve athletes’ performance, promoting oral health and preventing changes that could disrupt their sports routine. Objective To evaluate the dental conditions, habits, and oral health care of volleyball athletes, and their knowledge of the importance of oral health in sports performance. Methods Sixty-four male athletes participated in the study: 40 from the basic categories (16 ± 3 years) and 24 professionals (25 ± 5 years). For the assessment of oral conditions, changes in the temporomandibular joint, history of facial and dental trauma, and the presence of malocclusions and orthodontic treatment were verified. Hygiene was measured by the visible plaque index. To determine the athletes’ oral hygiene, they were asked how many times per day they brushed their teeth, flossed their teeth, or used oral mouthwash. Finally, we evaluated the athletes’ opinions concerning the importance of oral health and sports performance. Data analysis was performed using the Mann-Whitney and Fisher’s Exact tests, with a significance level of 5%. Results For most of the parameters evaluated, similar results were found between professional and baseline athletes (p&gt; 0.05). However, for the parameters “flossing” (p = 0.0027) and “facial/dental trauma” (p = 0.0444), significant differences were observed (p &lt;0.05) between the categories of athletes. Conclusion We conclude that professional athletes are more prone to facial/dental trauma, and that the presence of a dental surgeon to assist the team improves athletes’ overall oral health. Level of evidence II; Retrospective study.

title: PHYSICAL CAPACITY, RESPIRATORY AND PERIPHERAL MUSCLE STRENGTH IN HEART FAILURE

description: ABSTRACT Introduction The Glittre-ADL test is a submaximal test that involves sitting/lifting, stair climbing/descending, and weight-bearing activities, with considerable potential for use in assessing exercise intolerance in heart failure. Objectives To investigate the influence of heart failure on maximal physical (ergometric test - ET) and functional (6MWT and Glittre-ADL test) capacity, on respiratory (IPmax and EPmax) and peripheral (handgrip strength) muscle strength, and to study the correlation between the variables evaluated. Methods A prospective comparative study that assessed 44 subjects divided into two groups: G1, with 26 heart patients (20 men/6 women, 65.26 ± 8.50 years), and G2, with 18 healthy subjects paired with G1 on the basis of sex ratio, age and anthropometric characteristics (10 men/8 women, 60.72 ± 8.39 years). The comparison of categorical variables was performed using the chi-square test, while continuous variables were compared using the Student t test or Mann-Whitney test. The study of the correlation between variables was conducted using the Pearson coefficient for EPmax and handgrip strength, while the Spearman correlation coefficient was used for the others, with a statistical significance level of 5%. Results Groups were homogeneous in terms of sex ratio, age and anthropometric characteristics. G1 had a worse performance in all tests: ET (p = 0.016), Glittre-ADL (p = 0.001), 6MWT (p = 0.001), IPmax (p = 0.012), EPmax (p = 0.007) and handgrip strength (p = 0.036). There was a negative correlation between the Glittre-ADL test and 6MWT, and the Glittre-ADL test and handgrip strength in G1. Conclusion Heart failure resulted in impairment of maximal physical and functional capacity and of respiratory and peripheral muscle strength, with a negative correlation between functional capacity and handgrip strength. Level of evidence II; Prospective comparative study.

title: FACTORS ASSOCIATED WITH ANABOLIC STEROID USE BY EXERCISE ENTHUSIASTS

description: ABSTRACT Introduction Synthetic anabolic-androgenic steroids (AAS) were developed with the purpose of obtaining drugs capable of increasing protein synthesis associated with a lower degree of virilization. Its use is common among bodybuilders who aim to increase physical strength and muscle mass in the short term. However, AAS cause side effects, which restrict their therapeutic use. Objective To identify factors associated with AAS use by exercise enthusiasts at gyms in São Luís, MA. Methods A cross-sectional study was carried out at 17 gyms. The sample totaled 723 exercise enthusiasts, who answered a structured questionnaire with multiple choice questions related to their lifestyle and the consumption of nutritional supplements and AAS use. Logistic regression analysis was used to verify the association of socioeconomic, demographic and behavioral factors with AAS use. Results Of the 723 exercise enthusiasts, 10.65% reported having used AAS. Of these, 97.4% declared their awareness of some side effect caused by AAS use. Factors associated with AAS use were: being male, age between 20 and 29 years, consumption of food supplements and participation in exercise for over a year. Conclusion The prevalence of AAS use by exercise enthusiasts at gyms in São Luís is high, and the risk factors identified enable us to target specific populations with preventive actions.

title: SEX AND AGE-RELATED CHANGES IN PERFORMANCE IN THE DUATHLON WORLD CHAMPIONSHIPS

description: ABSTRACT Objective Our study analyses differences in performance between sexes, and changes in performance between age groups at Olympic distance during the ITU Duathlon World Championships, held between 2005 and 2016. During this period, a total of 9,772 duathletes were analysed (6,739 men and 3,033 women). Methods Two-way analyses of variance (ANOVA) were used to examine sex- and age-related differences in performance (time, percentage of time and performance ratio) in the first running and cycling legs, the second running leg, and total race for the top 10 male and female athletes in each age group at the Duathlon World Championships. Results The age group with the highest participation, in both male and female categories, was 40-44 years, and it was found that the mean age of female finisher participants across all age groups was 23.5±12. With regards to performance, the best results for total race time and the cycling segment were achieved in the 30-34-year age group, for both male and female athletes. With regards to performance in the first and third segments (running legs), the best times were achieved in the 25-29 and 30-34 age groups, for men and women respectively. Conclusion According to the results of our study, the best results in the professional career of a duathlete are achieved at between 30 and 35 years, therefore the athlete should incorporate this factor into their training plan. Level of evidence III; Retrospective comparative study.

title: ENDOTHELIAL NITRIC OXIDE CONCENTRATIONS IN THE SALIVA OF JIU-JITSU ATHLETES

description: ABSTRACT Introduction This article discusses the production of nitric oxide under the influence of sport-specific physical training, measured by the salivary nitrite of Jiu-Jitsu athletes. Objectives To verify the potential of the sport to produce optimal levels of nitric oxide stimulated by exertion, and to quantify training-related nitric oxide concentrations. Method The study participants were 14 volunteer athletes from the Tatame project (extension project), who were monitored for nine months in their training routine, providing samples of unstimulated saliva. Samples were collected each month, in three periods of the day: in the morning upon waking, immediately before training, and immediately after training. Salivary nitrite was quantified by the colorimetric Griess assay. Training heart rates were also monitored in order to establish training intensity. Results Mean monthly salivary nitrite levels showed a significant correlation with mean monthly heart rates, suggesting that salivary nitrite responds to training. However, salivary nitrite concentrations measured immediately after training were always lower than in the pre-training period. Conclusion The post-training reduction in concentrations was due to the nature of the sport studied, since because it involves a fight, the intense sympathetic stimulation inhibited salivary gland activity and irrigation, preventing salivary nitrite from producing an increase in circulating nitric oxide. Level of evidence IV; Case series.
