Summary: This study compares the effects of standard warm-up versus warm-up using stretching exercises on the physical performance of male youth soccer players. The results show that stretching-based warm-up has no effect on jump height, sprint speed, and ball kicking speed of male youth soccer players compared to standard warm-up.

Summary: This study compared the activity of abdominal muscles during the abdominal rise on the ball with the traditional crunch. The results showed that the abdominal rise on the ball activated the transversus abdominis, external oblique, and internal oblique muscles more effectively, while the activation of the upper and lower rectus abdominis and erector spinae muscles was lower.

Summary: This study investigated whether the expectancy of subjects on static stretching effects could influence strength-endurance performance. The manipulation of subjects' expectancy showed that positive information about static stretching improved performance in the last set of exercise, while negative information did not have a significant impact. Expectancy may play a partial role in influencing strength-endurance performance.

Summary: This study presents three fundamental models for modelling the bivariate scores in possessive ball-sports. These models can be used for prediction, experimentation, and explanation. The Markov-match model is a new model that complements the binomial-match model. The Markov-match model induces a larger correlation between the scores of competitors but slightly more tied outcomes.

Summary: This study investigated the effects of long-term stretching on maximal strength, muscle cross sectional area (MCSA), and range of motion (ROM). The results showed that stretching significantly increased muscle mass, maximal strength, and ROM. Additionally, stretching induced contralateral force transfer. The study suggests that stretching-induced muscle damage and central neural adaptations may be responsible for these effects.

Summary: In collective motor situations, creativity and empathy are closely connected to cognitive and affective processes. This study aims to propose indicators to examine the relationship between sociomotor empathy and motor creativity in an ecological situation. It also investigates the potential influence of two different collective games (handball and Sitting ball) on the type of links between empathy and creativity.

Summary: The study found significant asymmetry in body musculature and grip strength among handball players, especially in trunk musculature. Morphological asymmetry may impact sports performance and increase the risk of injury. Therefore, emphasizing the importance of individualized symmetrization during sports practice and consistent monitoring of asymmetries is crucial for improving performance and minimizing injury risk.

Summary: This study examined the fitness profiles of male Team-Handball players in the Italian national team of different competitive levels. Significant differences were found in anthropometrics, jumping, power, sprint, agility, and aerobic fitness between senior and junior players, as well as among different positional roles. Individualized training approaches may be necessary for young handball players based on these differences.

Summary: This study found no significant differences in quadriceps flexibility, strength, muscle activation time, and patient-reported outcomes between patients with patellofemoral pain who had inflexible quadriceps performing static or dynamic quadriceps stretching exercises. Therefore, both static and dynamic stretching exercises may be equally effective in improving pain and function in this patient population.

Summary: During remote classes, undergraduate students experienced high levels of depression and anxiety, but low levels of fear of COVID-19. Factors such as female gender, poor health status, lack of physical activity, and strict adherence to restriction measures were found to be associated with higher levels of fear, depression, and anxiety. These findings can be utilized to develop interventions, including physical activity programs, to address mental health issues among students.

Summary: This study compared the effects of different aerobic training protocols on cardiometabolic variables in patients with type 2 diabetes mellitus (T2DM). The results showed that low-volume high-intensity interval training (HIIT) can improve cardiorespiratory capacity more effectively than low-volume moderate intensity continuous training (MICT). Other variables also showed improvements with all three training protocols.

Summary: Male athletes generally outperform female athletes in endurance sports due to higher VO(2)max values. However, when adjusting for lean mass, the differences in VO(2)max between sexes become insignificant. This suggests that lean mass may play a role in explaining sex differences in performance.

Summary: Muscular weakness and strength imbalance in the thigh muscles are risk factors for knee injuries. Hormonal changes during puberty affect muscle strength, but their effects on muscular strength balance are unknown. This study compared knee flexor strength, knee extensor strength, and strength balance ratio between prepubertal and postpubertal swimmers of both sexes. The findings suggest that postpubertal swimmers have higher muscle mass and peak torque than prepubertal swimmers, indicating a potential higher risk of knee injuries.

Summary: This study compared the differences in ventilatory threshold, respiratory compensation point, and maximal aerobic speed between male and female triathletes in an Olympic triathlon race. The results showed that male athletes had significantly higher maximal oxygen uptake and maximal aerobic speed compared to female athletes, but there were no gender differences in the percentage of maximal oxygen uptake reached at the ventilatory threshold and respiratory compensation point. The average race speed did not differ between sexes, but female athletes ran at a higher percentage of speed at the respiratory compensation point.

Summary: Performance in endurance sports decreases with aging due to cardiovascular and musculoskeletal aging, but the factors most affected by aging are still unclear. This study compared two groups of runners (< 50 and > 50 years of age) based on their oxygen uptake, ventilatory threshold, and respiratory compensation point. The younger group had higher oxygen uptake and lean mass-adjusted oxygen uptake compared to the older group, indicating a significant difference. Both central and peripheral factors are negatively affected by aging, but the effect is greater on central factors. These findings contribute to our understanding of how aging affects master runners.
