Muscle strength and anaerobic performance in football players with cerebral palsy

Abstract

BACKGROUND: This is the first study that quantified the anaerobic performance in football players with cerebral palsy (CP). OBJECTIVE: This study aimed to examine anaerobic fitness in a population of football players with CP using vertical jumping (VJ) and Wingate tests.

METHODS: Twelve players (age 26.8 ± 4.8 yr, body mass 66.2 ± 4.8 kg, height 173.7 ± 6.4 cm, body mass index 22.2 ± 1.9 kg m(-2)) from the Spanish National Football Team with CP which had 9.4 ± 3.7 years of playing experience performed the VJ and Wingate anaerobic tests.

RESULTS: Vertical jump height was 20.0 ± 1.2 cm for squat jump (HSJ) and 23.9 ± 5.4 cm for countermovement jump (HCMJ). Wingate test peak power (PPOW) was 490.6 ± 125.8 W (7.35 ± 1.53 W kg(-1)). HCMJ was largely (r = -0.631, p = 0.028) and very-largely (r = -0.710, p = 0.01) associated with PPOW (W kg(-1)) and mean power output (MPOW) (W kg(-1)), respectively. Squat jump test peak power (W) showed a large association (r = -0.656, p = 0.021) with MPOW (W and W kg(-1)). The CMJ height resulted 19.5% higher than SJ.

CONCLUSIONS: Results showed low VJ and anaerobic capacity of football players with CP compared to national players without CP and the general population. In football players with CP the difference (19.5%) between VJ with or without countermovement (CMJ-SJ) was higher than reported for national players without CP. Further studies examining the effect of football practice on neuromuscular performance in subjects with CP are warranted.
