Summary: This study aimed to investigate the differences between positions, the influence of the amputation level or defect of the lower limb (LD), the differences in running performance between halves, and the relationship with the final match result in amputee football (AF). The findings showed that midfielders had significantly higher running performance parameters compared to other positions, and players with LD had significantly higher running performance than those with below the knee (LA) or over the knee (HA) amputations. Running performance decreased in the second half of matches. The trend of running more when losing could be observed, but the differences were not statistically significant.

Summary: This study aimed to investigate the effects of different pitch sizes and visual occlusion on youth players. The results showed that in larger pitches, players covered more distance while walking but less distance while running with visual occlusion. The number of successful passes was lower with visual occlusion, and the distance to the opponent's team centroid was more regular. In larger pitches, players had greater distance from both team's centroid and higher maximum speed. Coaches can use these findings to adjust training and match pitch sizes, as well as to enhance players' ability to use their non-dominant foot during visual occlusion and promote passing during normal situations.

Summary: This study aimed to address the issue of data overload for professional Australian football team practitioners by applying data reduction methods to athlete-monitoring measures. The results showed that monitoring player exposure to maximum speed over a chronic time frame is more appropriate, and perceived soreness represents a distinct element of a player's perception of wellness. Summed-variable and single-variable approaches following PCA of athlete monitoring data are novel methods of data reduction.

Summary: This study aimed to examine the acute effects of moderate-intensity aerobic and high-intensity interval exercise protocols on Asprosin and Brain-Derived Neurotrophic Factor (BDNF) levels in inactive normal weight and obese individuals. The results showed that serum asprosin was higher and BDNF was lower in the obese group compared to the normal weight group. Both moderate aerobic exercise and high-intensity interval exercise significantly decreased asprosin levels in both groups. The obese group showed a significant increase in BDNF levels after high-intensity interval exercise. Acute exercises of different intensities have important effects on appetite regulation hormones, particularly in the obese group.

Summary: The study analyzed the effects of foreign players on Turkish Super League matches by examining 1836 competition data from 6 seasons between 2014 and 2020. The results showed a positive correlation between the number of foreign players and variables such as passes, accurate passes, precise passes on the opponent's field, pass difference, and ball possession difference. However, no association was found between the number of foreign players and big team superiority. These findings suggest that increasing the number of foreign players may improve the game quality and indicate a shift towards a tactical possession-based competition.
