Figure 8From: Leg joint power output during progressive resistance FES-LCE cycling in SCI subjects: developing an index of fatigueResistance vs. Knee Power Output. Mean KPO decreased with increasing resistance. Since cadence remained nearly constant between 0/8th and 1/8th kp, the decrease in KPO is attributed to a decrease in force generation in the quadriceps and/or hamstring muscles.Back to article page
