<jats:p>The aim of this study was to evaluate the effectiveness of various forms of physical activity (PA) among male students in physical education (PE) programs offered by universities in Poland, Hungary and the United Kingdom. The study involved 200 full-time male university students (mean age: 19.86±0.82), enrolled in nine different PA programs. The participants’ anthropometric traits and body composition parameters were determined with the InBody analyser. Based on the students’ physiological parameters, the effectiveness of various types of PA was measured with Suunto. Ambit3 peak heart rate monitors during 60 minutes of physical exertion. The average values of body mass, body mass index (BMI), body fat mass (BFM), percent body fat (PBF), waist hip ratio (WHR), and visceral fat (VFL) were significantly (p&lt;0.05) lower in students who performed jogging, followed by sauna (JFBS) and martial arts than in the remaining PA groups. Minutes of difficult and very difficult intensities were highest in martial art students, followed by jogging students, and they were significantly (p&lt;0.05) higher than the values noted in the remaining PA groups (golf, bodybuilding/fitness, swimming, general PE classes, cycling and individual training). Physiological parameters were significantly (p&lt;0.05) lowest in golf players and students who trained individually. Martial arts and JFBS are the most effective types of PA among male university students. Students performing martial arts and JFBS were characterized by the lowest relative, body fat, whereas students who practiced swimming had the highest body fat levels in the population sample.</jats:p>

<jats:p>This study aims to compare the effects of repetitive sprint and calisthenics training methods on athletic performance improvement. The study was carried out with the voluntary participation of 20 international level kickboxers. Athletes were randomly assigned into two groups as Repetitive Sprint Training Group (RSTG) (n=10; ̄age: 20, 20±1,32 years) and Calisthenics Training Group (CTG) (n=10; age: 21,20±1,23 years). Athletes participated in the training of their groups for six weeks, three times a week, every other day. The effects of training methods on the performance improvement of athletes were examined by measurements and tests performed at the pre-test (T1), interim-test (T2), and post-test (T3) stages. Athletes' height, body composition (body weight, body mass index, body fat mass), aerobic endurance (VO2max), peak anaerobic power, and isometric leg (knee, flexion-extension) strength values (60º/sec- 90º/sec) has been examined. At the end of the study, the data were analyzed at a 95% significance level. The results of the study revealed that the repetitive sprint and calisthenics training methods were effective on body composition, aerobic endurance, anaerobic power, and isokinetic strength parameters (p1&lt;0.05), but the effect level was similar in both training methods (p2&gt;0.05). Repetitive sprint and calisthenics training methods are both effective in regulating the body composition of athletes and accelerating aerobic endurance, power, and strength progress, but when designed at similar training intensity, both methods have similar effects.</jats:p>

<jats:p>The aims of this study were to estimate the influence of inertial training on knee extensor muscle strength and power and evaluate the effect of that training on functional fitness in physically active older women. Twenty-two physically active women ages 58-70 years were randomly divided into a training (T) and a control groups (C). The T group performed inertial training using the ITMS three times per week for five weeks. Each training session included three exercise sets involving the knee extensor muscles. The 30-second chair stand, 8-ft up-and-go, and stair climbing tests were used to estimation of functional fitness. Significant post-training increases of average force (55%) and power (62%) were noted in the T group (p ≤ 0.05). No significant magnitudes of changes were observed in the C group. Changes in functional tests did not differ significantly between T group (2.9-5.6%) and C group (0.6-5.4%). Post-training changes on ITMS were not significantly correlated with changes in functional tests. Inertial training proposed here induced significant improvements in knee muscle strength and power in physically active older women, but the transfer of post-training gains to functional fitness was poor. It seems that the 30-second chair stand, 8-ft up-and-go, and stair climbing tests are undemanding tests for women with very good functional mobility and further study to estimate post-inertial training transfer should be done using more demanding tests for this sub-population.</jats:p>

<jats:p>The aim of the study was to determine the relationship between adolescents’ frequency of participation in physical education and physical activity and their amount of screen time. The study included 1,502 girls and 1,379 boys aged 14–16 years. We measured the participants’ frequency of participation in physical education classes, physical activity, and sedentary behavior by means of a questionnaire-based survey. We found that participation in physical education classes was associated with higher levels of physical activity in boys and girls, less time spent on electronic devices in both genders, and less time devoted to watching TV in girls. Girls participated in physical education classes more often, had lower levels of physical activity, and spent less time on sedentary activities than boys. In conclusion, increasing the frequency of participation in physical education classes may be an effective strategy for reducing physical inactivity and sedentary lifestyles in adolescents.</jats:p>

<jats:p>Given that adolescents and young people spend most of their time in the educational system, advancements in neurodevelopmental research emphasize the important and complex role of peers’ influence on adolescents’ behaviour, suggesting that supportive programmes led by peers have a strong potential benefit (King, &amp; Fazel, 2019). In many cases peers are the most important source of social support, and are therefore an important target group to investigate the factors of risk, signs of poor mental health and ways to assess their health behaviour and awareness of the care which should be taken regarding their mental health, as well as the resources and prevention models. The wish is to study whether there are differences regarding the mental behaviour in certain characteristics of susceptibility to peer pressure as a risk for the mental health of students of the Faculty of Educational Sciences of the Juraj Dobrila University of Pula and students of the Faculty of Teacher Education of the University of Zagreb, Division of Petrinja (N=440). The set hypothesis states that there is a statistically significant difference among students of the faculty in Pula and those in Petrinja in their assessment of certain features of peer pressure susceptibility as a possible risk for mental health. The results obtained at the x2-test showed a statistically significant difference between certain peer pressure features among students regarding their study environment linked to hanging out with peers who consume drugs and being tempted to try them, getting involved in risky behaviours if their peers ask them to, and betting or gambling because their friends also do that. The results indicate that in smaller communities social control and conformity in the students’ behaviour is more present due to their wish to fit in a peer group as well as possible, suggesting the need for strengthening the positive health behaviour of young people during their whole education in order to secure a healthy and productive adult population.</jats:p>

<jats:p>The article presents research materials relating to the study of the individual characteristics of the 2D:4D finger index in young athletes in pair female acrobatics and gymnastics. The aim of the study is to study and comparatively analyze the features of the 2D: 4D finger proportions in the "upper" and "lower" female partners in paired female acrobatics and among the female athletes involved in artistic gymnastics, referred to adolescence; confirmation of the influence of the 2D:4D finger ratio on the athletic capabilities of athletes and the formation of their sexual somatotype. It has been proved that the presence in these groups of female athletes with certain values of the inverse, andromorphic sexual somatotype indicates an increased level of testosterone in the body of these athletes and inverse adaptive changes with the formation of masculinization phenomena in them. Research methods and organization. To conduct research on the features of the 2D:4D finger proportions in the "upper" and "lower" female partner athletes in paired female acrobatics and in athletes engaged in artistic gymnastics, the following methods were used: anthropometric method to determine: IPD) and somatotyping according to the classification of J. Tanner and W. Marshall; 2) measurement and comparison of II and IV fingers of the hands of athletes using the finger ratio method according to J.T. Menning – 2D:4D Digit Ratio; 3) as well as the method of literary analysis, using available sources of information; 4) method of mathematical statistics. Organization of the study. This study was conducted in 2019-2020 with the involvement of 31 pairs of acrobats and 59 athletes involved in artistic gymnastics in Ukraine (Nikolaev and Poltava). "Lower" acrobats and gymnasts (n=90) - adolescent – 19.35±1.07 years; "Upper" acrobats (n=31) – pubertal age – 14.68±1.14 years (p≤0,01). Their experience in these sports ranged from 2.5 to 10 years. The level of sportsmanship – from I-III sports category to a candidate for master of sports, master of sports. Research results. After carrying out the study of the necessary anthropometric measurements for each participant (indicators of the width of the shoulders and pelvis, the length of the II and IV fingers of both hands) and processing the obtained anthropometric values, the values of the sexual dimorphism index (SDI) in each study group were determined by mathematical recalculation.</jats:p>

<jats:p>Low Back Pain (LBP) is commonly classified as civilization disease. Many authors assume that about 80% of the population over forty have at least one major episode of pain in the lumbar area. Many of those patients demonstrate lumbosacral radicular symptoms. Sciatica usually develop as a result of a disc-root conflict and can disturb patients posture and balance. The objective of this study was to assess the effect of the visual biofeedback balance control training in patients suffering from sciatica on posture and balance. This was a randomized clinical study with control group, single-blind. Sixty suffering from sciatica patients (54% females) in the age between 20 and 83 met the inclusion and exclusion criteria. In the experimental group (VBF) in addition to comprehensive rehabilitation, visual feedback balance training was used. In the control group (KT) except comprehensive rehabilitation the kinesiology taping was applied within the lumbar region. For outcome measure center of foot pressure deflection, execution time, Bohannon's standing one-leg test, distribution of limb loads, Functional Ambulatory Category, Timed Up and Go, lumbar spine mobility, Laségue symptom, neurological symptom examination and the Visual Analog Scale has been used. In results: visual feedback balance control training using the balance platform had a statistically significant impact on execution time, standing on one leg, spine mobility, gait, coordination and pain. Dynamic kinesiotaping had a statistically significant effect on COP sway, balance, gait, coordination and pain. Feedback balance control training was more beneficial than dynamic kinesiotaping, although not statistically significant. In the VBF group no statistically significant effects on COP sway and distribution of limb loads has been observed. No effects of gender, side of sciatica (left/right) nor BMI has been observed. Statistically significant effect of visual feedback balance control training was observed in both groups in the age below 55. No side effects have been noticed.</jats:p>

<jats:p>In wheelchair basketball the observation of active trunk movement during a game is done by a qualified panel of classifiers. Players are allocated into one out of eight class. In the past, the map of the volume of action for each class player was created based on classifiers’ experience and knowledge (in qualitative way, without the range of trunk movement). Based on Paralympics’ classification standards there is a need to provide quantitative data for the current classes. The aim of this study was to create the map and reference values of the volume of trunk action of wheelchair basketball players and to check if there are differences in results between players representing different functional classes. The second aim was to investigate if there are significant benefits of using additional equipment with the sport wheelchair like sports straps that help players to achieve the greater volume of trunk action. Sixty-eight players divided into functional classes were asked to perform the maximum active trunk range of movement in three planes, in a sport wheelchair with straps and without straps, that was measured by the Kinect for Windows V2 sensor. The differences in movement was assessed by the t-test or the Wilcoxon test, differences between classes were done by ANOVA and the post hoc Tukey test. The discriminant analysis was calculated. Significant greater volume of trunk action in each plane was noticed in a sport wheelchair with straps (p &lt; .05). There were observed significant differences in trunk movement in three planes between neighboring classes (p &lt; .05). 76.9% original grouped cases were correctly classified. The accuracy of the current classification system in wheelchair basketball was confirmed. The map and reference values of the volume of trunk action will be helpful for all wheelchair basketball stakeholders. Trunk flexion and rotation discriminate the most effectively players. All class players should use appropriately fitted straps around hips during wheelchair basketball game, for safeness and wider volume of action.</jats:p>

<jats:p>The morphological characteristics of elite basketball players are of great interest to some authors in order to define the best morphological profile for a particular playing position and different levels of competition. The aim of the research was to determine the differences in morphological characteristics in professional basketball players in relation to the playing position in different league competitions and to determine the relevance of these characteristics for success in the game. The survey included a sample of 773 elite basketball players competing in five different leagues in Europe. In our study, we found that centers are significantly taller and heavier than guards and forwards are. In addition to other components of basketball (technique, tactics, coach strategy), body height, body mass and body mass index play a major role in overall performance in a basketball game in all positions. The obtained data can help coaches in the scouting process in which leagues in Europe are played by players with certain morphological characteristics in relation to the playing position.</jats:p>

<jats:p>The aim of the work was to study the body reaction to high intensity interval training. The study included 92 women aged 18 to -35. People who have been engaged in organised, regular physical activity (at least twice a week) were qualified to Group 1. Group 2 were physically inactive persons. All subjects performed interval training in the Tabata formula - two 4-minute sequences. The exercise carried out in the first part is elevating the legs from the “plank” position, in the second part, the hands were elevated from the same position. The pulse rate, the Borg Scale and the VAS pain rate scale (24, 48, 72 and 96 h after exercise) were used to assess the exercise intensity. The respondents from both groups performed the training at a similar intensity: the average heart rate after workout was 131 beats per minute. The highest pain of all muscle groups (when added together) was recorded 24 hours after training. The highest pain intensity during the four days after the training concerned the back and abdominal muscles in Group 1 and the muscles of the abdomen, back and arms (front and back). The intensity of abdominal and arm muscle pain (front) was significantly higher in Group 2. The proposed 15-minute workout planned in the form of Tabata evoked similar cardiovascular reactions in both groups and a similar subjective evaluation of intensity. Individuals who were physically active before the introduction of restrictions related to the COVID-19 pandemic had less pain in the muscular system after the applied training.</jats:p>
