Figure 6From: Leg joint power output during progressive resistance FES-LCE cycling in SCI subjects: developing an index of fatigueResistance vs. Hip Power Output. The height of the bars represent the mean hip power output for the subject group at each resistance level. Negative values represent power absorption, where the direction of force generation opposes the direction of cycling motion. Positive values indicate power exertion, where the direction of force generation and cycling motion coincide. The range between the two tails indicates the standard error of the mean. Standard error was set at 95%.Back to article page
