Method: After assessment of body composition, 20 male team sport players (age 20.7 1.1 years; body mass 77.1 11.5 kg) were divided into low- (n = 10; 0.11 0.03) and normal- (n = 10; 0.27 0.09) fat groups based on FM:FFM ratio. Thereafter, participants completed measurements of knee extensor torque at 60 and 240 s􀀀1, countermovement jump flight time, plasma creatine kinase (CK) activity and perceived muscle soreness (VAS) before and at 0, 24 and 48 h after 10 10 maximal plyometric vertical jumps. Results: Evidence of muscle damage was confirmed by alterations in VAS, peak torque at 60 and 240 s􀀀1 and flight time at 0, 24 and 48 h after plyometric exercise (P < 0.05). CK was increased at 0 and 24 h (P < 0.05) but returned to baseline values by 48 h. No time by group e ects were observed for any of the dependent variables (P > 0.05). Conclusion: The current findings indicate that while muscle damage was present after plyometric exercise, the magnitude was similar across the two body composition groups. Applied practitioners can allow for a similar recovery time after plyometric exercise in those with low and normal body fat.CC0 1.0 Universalhttps://creativecommons.org/licenses/by/4.0/exercise-induced muscle damagestretch-shortening cyclefat massmuscle functionathletesArticle2411-5142Journal of Functional Morphology and Kinesiology
