(1) Background: Fatigue impacts neuromuscular performance, especially in endurance sports like rowing. The aim is to explore how continuous workload affects explosiveness and fatigue progression. This study examines acute fatigue during repeated race events by assessing vertical jump height, force output, and subjective fatigue over three consecutive days at the 2024 Hungarian National Rowing Championships. (2) Methods: Nine rowers (five women, four men; mean age 20.17 ± 1.73 years) competed in multiple 2000 m races over three days. Lower limb explosiveness was measured via countermovement jump (CMJ) using a Kistler force plate, pre- and post-race. Heart rate data were recorded with Polar Team Pro^®. Subjective fatigue was assessed using the ‘Daily Wellness Questionnaire’. (3) Results: We found a significant difference in the pattern of the medians of the force exerted by males during the jump between the results of the Thursday preliminaries (ThuQMe = 13.3) and the second final (ThuF2Me = −75.5). Women showed no notable changes. (4) Conclusion: Repeated high-intensity races induce neuromuscular fatigue in men, reflected in reduced explosiveness and increased subjective fatigue. Future research should incorporate biochemical markers to deepen the understanding of fatigue mechanisms.

Motocross is one of the most popular high-speed motorcycle races, which takes place on a naturally closed track with significant challenges. This study aimed to characterize anthropometric, circulatory, and lower and upper limb muscle properties based on laboratory and race-recorded characteristics. Male competitors (n = 3) aged 14 years (MX) were included in the study. All three boys have national and international experience. Metabolic characteristics (ventilation, oxygen consumption, and carbon dioxide production) and heart rate (HR) were measured in the laboratory while HR and speed were measured while racing. No significant difference was found between the three competitors in terms of HR during the race. In terms of number of sprints (No. sprint) and maximum speed (Speedmax), we found the most successful runner (highest finisher) to have the most sprints and maximum speed. Comparing the metabolic characteristics, it was found that racing was between the respiratory breakpoint (VT1) and the respiratory compensation point (RCP), but, in several cases, crossed the anaerobic threshold. While motocross riders are exposed to extreme conditions and high physical demands, in motorsport, victories depend not only on the athlete’s physical abilities but also on several factors such as driving technique, mental effort, equipment efficiency and resistance, race strategy, and team competence.

Background: Motocross riders’ performance is highly dependent on the characteristics of the motorcycles and the skills of the riders, and the actual environmental conditions. This study aims to describe the differences in anthropometric and physiological characteristics between internationally ranked adolescent males and nationally ranked motorcross (MX) peer competitors; Methods: Data obtained from young riders (n=14) were divided into internationally ranked G1 (n=5) and - nationally ranked G2 (n=9) young MX riders. We determined body composition and cardiorespiratory variables, and measured heart rate and movement-related data with Polar Team Pro system during the race; (3) Results: Blood lactate concentrations were evaluated before and after the race session. MX riders with an international ranking performed significantly better during both races (R1 and R2), which manifested itself in significantly shorter times per lap on average (difference for R1=14.8 s and for R2=16.7 s, respectively, p=0.017), more laps completed (G1 vs G2 approx.: 11.2: 9.9 laps for R1 and R2, p=0.019) and points scored (difference: R1=9.3 pts and R2=9.0 pts, p=0.014). There were no statistically significant differences in age between the two compared groups (p=0.559) and other anthropometric and physiological characteristics tested, with an exception of muscle mass percent (p<0.001); Conclusions: Current results showed that motocross probably places a heavy burden on riders, who need to be fit enough to maintain their position in the field.

Background: Nursing home residing older adults often experience fear of sickness or death, functional impairment and pain. It is diffcult for these older adults to maintain a physically active lifestyle and to keep a positive outlook on life. This study evaluated the changes in quality of life, attitude to aging, assertiveness, physical ftness and body composition of nursing home residing elderly through a 15-week organized resistance training based physical activity program. METHODS: Inactive older adults living in a state fnanced nursing home (N.=45) were randomly divided into two intervention groups and a control group. Both intervention groups were assigned to two physical activity sessions a week, but one of these groups also had weekly discussions on health and quality of life (Mental group). Data on anthropometric measures, ftness performance, as well as quality of life and attitudes to aging survey data were collected. due to low attendance rate 12 subjects were excluded from the analyses. Statistical analysis included paired Samples t-tests and repeated Measures analysis of Variance. RESULTS: Both intervention groups signifcantly improved their social participation, and their upper-and lower-body strength scores. Also, subjects in the Mental group showed improvement in agility ftness test and certain survey scales. No positive changes were detected in attitude towards aging and body composition measures in any groups. The post-hoc results suggest that Mental group improved signifcantly more than the control group. coNcluSioNS: regular physical activity with discussions on health and quality of life made a more meaningful difference for the older adults living in nursing home than physical activity alone. Due to the fact that all participants were in?uenced by the program, it is suggested to further explore this area for better understanding of enhanced quality of life.

Students who participate in well-planned and structured physical education (PE) lessons engage in significantly higher levels of physical activity than children who do not. Heart rate monitoring a useful tool to help both students and teachers understand the efficiency of the physical activity. The purpose of this study was to analyze primary school children’s body compositions and heart rates when performing different types of physical activities (gymnastics, mixed activities, ball games, athletics, and games). The sample included 10-12-year-old primary school boys (N=46) and girls (N=63) from the university’s cooperating school. To estimate their body compositions, standard anthropometric techniques were used. Polar RS400 heart rate monitors were used to monitor the heart rate of each child during the main parts of different types of physical education lessons. There were no differences between the genders for the body composition or for the maximal heart rate values in the different PE content areas. The lowest heart rate was recorded during gymnastics (148 beat*min-1), and the highest values were detected during the game activities and athletics (164.60 and 163.83 beat*min-1. For the mixed activities and ball games, the heart rates ranged between 154.06 and 156.52 beat*min-1. Physical activities that result in higher heart rate values required a greater contribution and adaptation of the cardiovascular system. However, activities that elicit a lower heart rate likely focus more on skill learning and acquisition. This data can be used as a resource for physical education teachers when planning and structuring PE classes.
