• Performance and Inter-Limb Asymmetry in Relation to Peak Height Velocity and Injury-Related Variables in Adolescent Male Soccer Players (2026) · Sports · cited 1× · doi

  The role of physical performance variables in change of direction, considering maturation and injury-related factors, remains poorly understood. There is limited evidence simultaneously examining biological maturation, unilateral neuromuscular performance, inter-limb asymmetry, change of direction performance, and injury-related variables in adolescent male soccer players.

• Adult age trends in athletic performances (1981) · Experimental Aging Research · cited 35× · doi

  Prior studies have not comprehensively compared different hypotheses to predict differential age trends across events. There is a need for a more accurate understanding of the effects of aging on athletic abilities. The study aims to address this gap by comparing five hypotheses and providing insights into maximal human physical performances.

• The Effects of Age and Height on Gait Smoothness in Adolescent Athletes (2024) · Children · cited 1× · doi

  The objectives of this study were, first, to better understand how one measure of gait stability changes during the adolescent growth phase and, second, to determine how these changes differ between the sexes. Our initial hypothesis that the sexes would differ in how their gait stability changed during the years surrounding peak height growth was supported by our results, though we were surprised to find little effect of height on the HarmonicRatio in males. The findings of this suggest sex differences in the effects of fatigue on gait stability during adolescence. In both sexes, several HarmonicRatio values increased with chronological age. Following a bout of fatiguing exercise, these improvements were eliminated for males and altered for females. The results of this study indicate the need for a reevaluation of sports progression based on chronological age in adolescents. Overall, the results presented here serve to highlight a notable need for further investi- gation into the apparently substantial differences between male and female adolescents in the development of gait stability during the years surrounding peak adolescent height growth. The application of this research to youth sports can help guide improvements to the progression of adolescent sports to minimize the risk of injury. Future studies are necessary to further investigate the effects of absolute height and chronological age on both general gait stability and trunk stability during gait. Additionally, the field of youth sports injury and motor coordination development would benefit from studies investigating the impacts of growth rate, both absolute and relative to height, and of absolute walking speed on gait stability. The results presented here indicate the need for further longitudinal research into the timing of adaptations in motor performance related to age, physical growth, and sex.
