Figure 4. Rate of muscle heat production (A) and mechanical efficiency (B).

Figure 4

Results are shown for 90 s of low intensity knee-extensor exercise with (OCC, □) and without thigh occlusion (CON-LI, ▪) as well as 90 s of high intensity exercise preceded by low intensity exercise (CON-HI, ▵). Mechanical efficiency was estimated as work performed divided by total energy turnover. Means ±s.e.m. are given. *Significant (P < 0.05) difference between CON-LI and OCC. † Significantly different from the first 20 s of exercise. *Significantly (P < 0.05) different from pre-exercise value.
