Impact of Centre-of-Mass Acceleration on Perceived Exertion, the Metabolic Equivalent and Heart Rate Reserve in Triathlete Spin Cycling: A Pilot Study
Authors: Evans Stuart , James Daniel , Rowlands David , Lee James
Published: February 2022

Indoor spin cycling has gained popularity as a training modality for triathletes. Part of its appeal is that it can form a component of a structured periodised training program and provide an alternative to outdoor cycling. Indices of physiological components (i.e., the metabolic equivalent, caloric cost, perceived exertion) and changes in the body position can be inferred by wearable technology such as an accelerometer. This pilot study aimed to investigate the relationship between the rating of perceived exertion, heart rate reserve, and the metabolic equivalent between the whole body centre of mass acceleration using a sacrum mounted triaxial accelerometer during 20 minutes of 6 varied power conditions of indoor spin cycling. Compared with other conditions, cycling at a steady state (>152-205 W) resulted in extremely large effects (> 0.9) in mediolateral acceleration and the rating of perceived exertion (p < 0.0001). The relationship between the body position (aerodynamic to drops) induced significant changes in anteroposterior acceleration magnitude (p < 0.0001), although moving from drops to the aerodynamic position was not significant despite a large increase in heart rate reserve and extremely large effects of perceived exertion. The rating of perceived exertion scale and the metabolic equivalent comparative to the whole body centre of mass acceleration magnitude and power displayed a strong correlation (r = 0.865). An individually determined whole body centre of mass accelerations combined with perceived exertion, the metabolic equivalent and heart rate reserve could potentially contribute to improved indoor triathlete spin cycling performance.

Published: February 2022

This study aimed to investigate the effect of water immersion (WI) on cardiac parasympathetic reactivation during recovery from handball training sessions in elite female players during a two-week training camp. On the first three days of both weeks, players completed a crossover design with one of three 60-min delayed post-exercise WI protocols or passive rest (PAS). Recovery interventions consisted of a period of 6-min cold-WI (10°C; CWI6) and two contrasting periods cold- and hot-WI (36°C): one session included 3 min cold + 2 min hot + 3 min cold and the other session 5 × 2 min with cold at the very end. Short-term measures of heart rate variability (HRV) were collected before and after handball training sessions, and after WI. Derived parasympathetic HRV indices collected daily showed lower values post-training compared to pre-training values (p < 0.0001, large ES). Individual handball training sessions revealed similar clear depression of the vagal tone throughout the training camp. The comparison between each WI protocol and PAS revealed significant time × condition interaction particularly for CWI6. All parasympathetic indices revealed higher post-recovery values in CWI6 than PAS (p < 0.001 –p < 0.0001, with large ES ranging from 0.86 to 0.94). Surprisingly, 60-min delayed post-training WI revealed for most of parasympathetic HRV indices higher values than pre-training. This study highlighted that post-exercise parasympathetic disruption was exacerbated in response to handball training, and the 60-min delayed WI recovery interventions improved parasympathetic reactivity. Cardiac vagal tone can be highly improved with CWI6 compared to PAS. For the purpose of HRV modulations, CWI6 is recommended for short-term recovery.

Published: February 2022

Mental toughness is a psychological construct related to successful performance in academics, management, and sports among other sectors. However, studies on the determinants of mental toughness with respect to different human endeavours have remained inconclusive. This study explored mental toughness characteristics of male university athletes in selected sports in relation to contextual factors of athletes’ age, playing experience, year of study, and the type of sport. The Mental Toughness Questionnaire (MTQ48) was used to collect data from male university athletes (n = 140). Results of this study showed significant difference in the following components of MT: lower scores in challenge (p = .015), emotional control (p = .005), and life control (p = .002) among athletes with shorter playing experience, and higher scores in life control (p < .001), emotional control (p = .021), and confidence in abilities (p = .009) in handball as compared to soccer players. Soccer players had significantly higher scores in the challenge component (p = .038) of mental toughness as compared to handball players. It was concluded that playing experience and the type of sport influenced characteristics of mental toughness among university athletes. Coaches, trainers, and sports psychologists need to consider these contextual factors to optimize mental toughness of athletes. Future studies should explore how specific contextual factors influence training environments and outcomes, as well as how stakeholders can leverage on the relationships between playing experience, the type of sport and mental toughness to augment athletes’ mental toughness and sports performance.

Authors: Kasińska Zofia , Urbański Piotr , Tasiemski Tomasz
Published: February 2022

The aim of the study was to determine the frequency, type and origin of the occurrence of injuries in amputee football. The studied group comprised all members of the Polish national amputee football team (n = 25). During the 9-month observation period, 13 players incurred 22 injuries. The incidence proportion was 48.0 per 100 athletes (95% Cl, 28.4-67.6) and the incidence rate was 5.73 per 1000 athlete-days (95% Cl, 3.33-8.12). The study showed that 32.8% of the injuries were to the thigh, 13.6% to the ankle, and 9.1% to the knee. The obtained results indicate that amputee football players rather frequently incur play-related injuries, but a single athlete incurs relatively few of them, with the lower limb being most commonly injured.

Published: February 2022

This study aimed to investigate the impact of crowd absence due to the COVID-19 pandemic on home advantage in Series A and B of professional Brazilian male soccer. Moreover, we sought to compare the home advantage between different competitive levels. Data from 2018 to 2020 Brazilian professional soccer championships (Series A and B) were analyzed, consisting of 2280 matches. The effect of home advantage was calculated in relation to the number of points won, the number of wins, goals scored and goals conceded. Our results indicated that home advantage was reduced in Serie A. Specifically, the 2020 (absence of the crowd) and 2019 seasons showed smaller home advantage compared to the 2018 season. On the other hand, Serie B analyses indicated no changes in home advantage over the seasons analyzed. The comparison of home advantage between competitive levels indicated higher home advantage in Serie A, exclusively in the 2018 season. In addition to the absence of fans, other changes occurred in elite sports due to the pandemic, such as changes in rules and the calendar. Considering that home advantage is affected by multiple interacting factors, it is important to investigate specific sports leagues across the world to determine which factors had the greatest impact on the advantage of playing home matches.

Published: February 2022

Background

COVID-19 related acute respiratory distress syndrome (ARDS) requires intensive care, which is highly expensive in lower-income countries. Outcomes of COVID-19 patients requiring invasive mechanical ventilation in Pakistan have not been widely reported. Identifying factors forecasting outcomes will help decide optimal care levels and prioritise resources.

Methods

A single-centre, retrospective study on COVID-19 patients requiring invasive mechanical ventilation was conducted from 1st March to 31st May 2020. Demographic variables, physical signs, laboratory values, ventilator parameters, complications, length of stay, and mortality were recorded. Data were analysed in SPSS ver.23.

Results

Among 71 study patients, 87.3% (62) were males, and 12.7% (9) were females with a mean (SD) age of 55.5(13.4) years. Diabetes mellitus and hypertension were the most common comorbidities in 54.9% (39) patients. Median(IQR) SOFA score on ICU admission and at 48 hours was 7(5-9) and 6(4-10), and median (IQR) APACHE-II score was 15 (11-24) and 13(9-23), respectively. Overall, in-hospital mortality was 57.7%; 25% (1/4), 55.6% (20/36) and 64.5% (20/31) in mild, moderate, and severe ARDS, respectively. On univariate analysis; PEEP at admission, APACHE II and SOFA score at admission and 48 hours; Acute kidney injury; D-Dimer>1.5 mg/L and higher LDH levels at 48 hours were significantly associated with mortality. Only APACHE II scores at admission and D-Dimer levels> 1.5 mg/L were independent predictors of mortality on multivariable regression (p-value 0.012 & 0.037 respectively). Admission APACHE II scores, Area under the ROC curve for mortality was 0.80 (95%CI 0.69-0.90); sensitivity was 77.5% and specificity 70% (cut-off ≥13.5).

Conclusion

There was a high mortality rate in severe ARDS. The APACHE II score can be utilised in mortality prediction in COVID-19 ARDS patients. However, larger-scale studies in Pakistan are required to assess predictors of mortality.

Introduction

Home confinement during the COVID-19 pandemic reduced the physical activity level and exacerbated other unhealthy behaviours such as vices and eating disorders. This study analyses the risk factors predisposing to weight gain in young adults during COVID-19 home confinement.

Material and method

Four hundred thirty-three students, aged between 19 and 25, participated in an online survey to understand the factors associated with weight gain. The following lifestyle dimensions were investigated in a regression model: physical activity, personal experiences, occupation, risk of vices.

Results

We have found significant associations between weight gain (as a dependent variable), and frequency of physical activity (p = 0.009), occupational performance (p = 0.002), and alcohol consumption (p = 0.002). Male respondents are more likely to have gained weight during isolation. For an increase of one unit in the frequency of playing sports, we expect an odd of 0.25 (p = 0.048) for the respondents’ weight loss. Moreover, if the occupational performance increases by one unit, a weight decrease by a rate of 0.52 (p =0.02) is expected.

Conclusion

In conclusion, young adults less engaged in physical activity, who assessed their occupational performance as lower, and who consumed alcohol more often during home confinement are the most likely to have gained weight.
GUIDELINES FOR THE GASTRONOMY OF DOBROGEA,
FOUNDATION FOR THE DEVELOPMENT OF THE LOCAL
GASTRONOMIC TOURISM
Authors: Casangiu Siea Laetitia
Published: February 2022

In the present study we analyse aspects related to the culinary side of the region of Dobrogea (Romania). The
main research methods for the present article were the comparative study of specialized literature, with coverage
of the main publications dedicated to the chosen topic, and the survey done through a questionnaire, launched
with the purpose of checking the level of knowledge of the gastronomy of Dobrogea among the consumers and to
identify its characteristic elements in order to consider it as vector for the local gastronomic tourism. The results
of our research have highlighted the fact that customers give a high importance to the culinary aspect when
choosing a holiday destination, and that the local Dobrogean dishes, wines, desserts and the quality products
which have received recognition at a European level are not sufficiently known by the general public. This fact is
due, on one side, to the insufficient information given about the geographical origin of the products during the
marketing and sale phase and, on the other side, to a general lack in promotion for Dobrogean products, especially
in other regions of Romania and abroad.

Progress in low-frequency vibration processing technology for metal welds in shipbuilding and mamachine engineering
Authors:   JSC Shipbuilding and Ship Repair Technology Centre (SSTC), St. Petersburg, Russia, Stepanov V.V.
Published: February 2022

Residual welding strains and stresses affect strength, lifetime and reliability of shipbuilding hull structures and a wide spectrum of welded metal structures applied in manufacturing of machine tools, machines and railroad cars, as well as in building industry. Welding strains also increase man-hours required for manufacturing. A traditional way of residual stress mitigation in shipbuilding and other industries is thermal processing which is known to be a costly and labour-intensive operation. An alternative process is low-frequency vibration processing that is relatively easy and highly cost-efficient. Low-frequency vibration processing basically means that metal structures are subjected to alternating-sign loads at resonant or near-resonant frequencies by means of an electromechanical vibration exciter. Size stabilization in this kind of processing is achieved through mitigation and re-distribution of the first-kind residual stresses, i.e. those equilibrating over the entire product or its large elements, so that material structure comes to a more stable equilibrium. This paper discusses SSTC experience in the induction of low-frequency vibration processing of welded metal structures to the practice of shipyards and machine manufacturing enterprises, as well as describes state-of-the-art equipment for its performance and the equipment used to assess and check its results.
Short-circuit currents versus inductive reactances of turbo-genset for different types of shorts
Authors:   JSC Power Machines, St. Petersburg, Russia, Dorzhieva B.S.
Published: February 2022

This paper discusses how short-circuit currents of turbo-genset depend on its inductive reactances for the cases of triple-, double- and single-phase shorts. The study tackles air-cooled turbo-gensets. The purpose of this work was to investigate the effect of changes in synchronous, transient and subtransient inductive reactances of turbo-genset upon short-circuit currents for different types of shorts. Short-circuit currents were calculated as per Park-Gorev equations. The changes in currents were plotted against both longitudinal and transverse axes. The results were further used to plot short-circuit currents as functions of subtransient and transient turbo-genset reactances. These plots show that even a minor change in subtransient and transient reactance results in a significant change of short-circuit current.

This paper discusses underwater robotic networks from the standpoint of stealthy surveillance by means of bio-inspired drones. “Bio-inspired” means that various hardware, software and technology solutions implemented in a robot have biological basis and rely on the studies in ethology and morphology of living organisms. In underwater robotics, this approach makes it possible to develop the vehicles that resemble sea life in terms of appearance and behavior and therefore are harder to detect for both animal and human observer, which facilitates the tasks of water area surveillance and fauna research observations. This work is meant to develop and refine a number of basic collective behavior patterns for this kind of robots, which is necessary to make robots as similar to the sea life in their operation area as possible to reduce their chances of being detected. Basic behavior algorithms for robots were developed as per the findings of ichthyological and ethological studies and also relying on certain points of the automata theory. A number of functions for the lower-level control systems were developed through simulation. The experiments were mostly performed in Robotic Test Tank of the Kurchatov Institute on a real shoal of underwater robots developed under this project. The results of this study made it possible to develop one of the basic patterns in shoaling behavior of robots, i.e. schooling after a non-established leader whose position is disputed. In real environment, this pattern was tested on three fish-like underwater robots with two-level control system. Another output of the study is a short-range infrared communication system for limited data exchange between drones. Experimental validation of this system and the pattern of schooling after a non-established leader implemented at the top level of robot control system have confirmed the viability of suggested solutions. This mechanisms, as well as technical and technological solutions yielded by this work will become the basis for further efforts towards development of a bio-inspired underwater robot. The algorithm of schooling after a non-established leader plays a key role in further improvement of collective behavior patterns for drones, like shoaling.

Abstract              Poverty is a social problem that requires effective and sustainable management. Many parties have made various efforts to overcome poverty. However, the poverty reduction model built tends to only use a charitable approach (generosity). So that it only creates a sense of dependence on aid, without creating a productive spirit for the poor. Therefore, in facing the times, it is necessary to digitize the correct mustahiq economic empowerment model. The type of research used is in the form of field research with qualitative methods. The study concludes that the proper digitalization of the mustahiq economic empowerment model can be carried out in a creative productive manner, namely the distribution of zakat that cannot be directly used or spent by the mustahiq. So that its possible use will have an economic impact on mustahiq with guidance and assistance through digital technology. Keywords: Digitalization, Empowerment, Mustahiq, Productive
