The Effects of TRX-Based Functional Training on Sprint, Agility, and Balance in Youth Football Players: A Controlled Experimental Study

Abstract: This study aims to investigate the effects of an 8-week TRX-based functional training program on sprinting, agility, and dynamic balance in young soccer players aged 12–15 years. The mean age of the participants was 14,0±0,83 years in the experimental group and 14,9±0,93 years in the control group. The average heights were 1,62±0,07 m and 1,65±0,07 m, respectively, and the average weights were 48,3±7,9 kg and 54,6±14,0 kg, respectively. The Arrowhead agility test, 20-meter sprint test, and balance measurements were performed. The experimental data were analyzed using the IBM SPSS statistical program (version 25.0, Chicago, IL, USA). In the agility test, a significant decrease of 0,10 seconds (1,08%) (p0,05). In the 20-meter sprint test, a significant decrease of 0,12 seconds (2,74%) (p0,05). In the group comparison, significant differences were found in the Arrowhead test (p
