FIGURE 3.

Specific work of shortening in the uphill, downhill, and control groups of the EDL muscle (a) and SOL muscle (b). The red bars represent a slow shortening speed and the blue bars represent a fast shortening speed. The EDL performed 52.3% more work than the SOL during the fast speed, and the EDL in the downhill group performed 46.3% more work than the SOL. On average, both muscles produced 54.1% more work during the slow versus the fast speed. Mean ± SE
