Mean peak isometric force of all participants measured at baseline (pre-injury), 0, 24, 48, 72 and 96 hours post damage represented as a percentage of baseline force. There is a significant main effect of time (p < 0.01). Across all 3 experimental groups an initial decrease in force was observed, followed by a gradual recovery. * indicates a significant decrease in muscle force compared to baseline measure. Significant differences were found between: 0 h and all others times (p = 0.031, 0.022, 0.012, 0.001) and between 48 h and 96 h (p = 0.034).
