This study, published in the journal Pediatric Exercise Science, investigates the association between resistance training skill performance and various fitness characteristics in adolescent male lacrosse players. The research involved 134 participants who underwent a series of tests to evaluate their anthropometric measurements, movement competency, and fitness levels.
The primary aim was to examine how the Resistance Training Skills Battery (RTSB) composite scores correlated with fitness measures, particularly focusing on the role of maturity status, defined by years from peak height velocity (YPHV). The study categorized the players into different maturity groups: 0.5 YPHV, 1.5 YPHV, and 2.5 YPHV.
Key Findings
- Total body fat percentage was found to explain 42% of the variance in RTSB scores for the 0.5 YPHV group.
- In the 2.5 YPHV group, vertical jump height emerged as the sole predictor of RTSB performance, accounting for 44% of the variance.
- Significant differences in competence were observed in specific exercises, such as push-ups and suspended rows, with more mature athletes outperforming their less mature peers.
The results suggest that muscular power and body composition are critical factors influencing movement competency among adolescent lacrosse players. The findings highlight the importance of considering maturity status when assessing resistance training skills and fitness in young athletes.
What this study does not show
This study does not establish a causal relationship between resistance training skills and fitness outcomes, nor does it assess long-term performance implications.
