Figure 3. Force, power and fatigability (reductions in power) of the knee extensors in young and old adults.

Figure 3.

The mean absolute isometric force and mechanical power output of the knee extensors were 24% and 47% lower, respectively, in the old compared to the young adults (A). Fatigability of the knee extensors was ~1.8-fold greater in the old compared to the young adults, with an average relative reduction in power of 77% in the old and 42% in the young adults (B). ∗Significantly different from young (P< 0.05). Values are the mean ± SE.
