Abstract
The purpose of the present study was to investigate if differences exist in neuromuscular qualities between different leagues in English male soccer. Twenty soccer players (age: 23.3±5.2 years, stature: 180.3±7.0cm, mass: 82.5±7.7kg) from English football league two (EFL2). 34 soccer players (age: 25.8±4.3 years, stature: 180.9±5.6cm, mass: 81.4±8.6kg) from National league (NL) and 23 soccer players (age: 27.5±4.3 years, stature: 182.1±5.5cm, mass: 84.1±8.0kg) from National league North (NLN). Each player completed three to five repetitions of the countermovement jump (CMJ), countermovement rebound jump (CMJRJ) and isometric mid-thigh pull (IMTP). Trivial to small differences were observed in CMJ jump height, CMJ momentum, relative average braking and propulsion force, time to take-off and modified reactive strength index (RSI) (p>0.265, d=0.05–0.55). However, moderate to large (p≤0.009, d=0.94–1.25) differences were observed in countermovement depth. Trivial to moderate differences were observed in absolute and relative peak net force and force at 100 and 250ms (p≥0.092, d=0.13–0.63). Trivial to moderate differences were observed in CMJRJ rebound jump height and rebound jump momentum (p≥0.440, d=0.17–0.41). NLN players had longer rebound contact time and lower rebound RSI, rebound average relative braking and propulsion forces to a large magnitude (p≤0.001, d=1.18–1.85), with small differences between ELF2 and NL (p>0.536, d=0.11–0.39). Lower reactive qualities of NLN players could explain observed leagues, considering their relationship with match scoring situations. All players would be considered weak (<30N/kg) and practitioners should prioritise lower limb strength across all leagues.
