Summary: This study used player location data from the 2021 Australian Football League season to describe the spatial characteristics and roles of players in the forward line. Results showed that teams differed in the dispersion of their forward players, but were similar in terms of player locations' centroids. Cluster analysis and visual inspection revealed the presence of different repeated structures or formations used by teams. Teams also showed variation in their choice of player role combinations in forward lines. The study proposed new terminology to describe the characteristics of forward line formations in professional Australian Football.

Summary: This study found that senior and junior rugby league players exhibit different patterns of improvements in lower-body strength and power during different phases of the season. Senior players showed increases in strength and power at the end of the preseason, but no changes during the in-season. Junior players did not show changes in strength, but had significant increases in absolute and relative strength and power during the in-season. These findings emphasize the importance of differentiating training programs for junior and senior athletes and targeting different physical qualities at different times of the season.

Summary: This study found that depression in retired elite level rugby league players was not significantly associated with lifetime history of concussions or number of years playing professional collision sport, but was instead correlated with current anxiety, stress, resilience, and life interference due to chronic pain.

Summary: This study evaluated the frequency and risk of same-year repeat concussions in the NFL, and found that the risk of repeat concussion was similar to that of a single concussion. Same-year repeat concussions also resulted in longer time missed compared to single or initial concussions.

Summary: This study analyzes the performance differences among AFL players based on their contract status. By examining AFL Player Ratings and contract data from 2013 to 2020, it was found that there is a difference in performance before and after signing a contract, particularly for players who signed mid-season. The correlation analyses also suggest that more consistent performers are less likely to see a decline in performance after signing a contract. These findings have implications for organizational decisions regarding player contracting timing and nature.

Summary: To ensure uncertainty in match outcomes, professional sporting leagues have used various competitive balance policies. The Australian Football League introduced a draft value index (DVI) in 2015 to refine its player draft operation. This paper aims to produce an alternative to the AFL DVI by using other measures of player performance.

Summary: The study aims to quantify and assess Head Impact Exposure (HIE) metrics among youth and collegiate football players. The study found that youth players experienced fewer impacts and lower impact magnitudes compared to collegiate players, with impacts during competition being more frequent and of greater magnitude than during practice at both levels.
