| Summary: | Aim: This study assessed the influence of fat mass to fat-free mass ratio (FM:FFM) on recovery from plyometric exercise. 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- (<i>n</i> = 10; 0.11 ± 0.03) and normal- (<i>n</i> = 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<sup>−1</sup>, 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<sup>−1</sup> and flight time at 0, 24 and 48 h after plyometric exercise (<i>P</i> < 0.05). CK was increased at 0 and 24 h (<i>P</i> < 0.05) but returned to baseline values by 48 h. No time by group effects were observed for any of the dependent variables (<i>P</i> > 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.
