Comparisons of countermovement jump and isokinetic performance in youth athletes: maturation and early sport specialization considerations (2022)
Thesis
Hofmann, C. Comparisons of countermovement jump and isokinetic performance in youth athletes: maturation and early sport specialization considerations. (Thesis). University of Salford

This thesis examines the impact of maturation status and single versus multiple sport participation on the physical performance of adolescent athletes across 6 studies. Study 1 investigated the test – retest reliability of isokinetic knee flexion and...

The countermovement jump (CMJ) has been suggested to be an important test of neuromuscular performance for rugby league (RL) players. Identifying force platform-derived CMJ variables that may be more applicable to RL positions (e.g., forwards and bac...
