The powers of the upper and lower limbs were measured using bicycle ergometers, and the most appropriate brake load to evaluate force- and speed-type powers was investigated (Experiment 1). Next, the power values in the force and speed types were compared between weightlifters (WL) and badminton players (BD) at our university (Experiment 2). In Experiment 1, the subjects were 12 male university students, and in Experiment 2, the subjects were 7 WL and 12 BD. Upper and lower limb powers were evaluated using bicycle ergometers, with the subjects pedaling at maximum speed for 5 seconds. The results showed that 1) the maximum power of the upper limbs was obtained at 3.5 kg (average) and showed the highest correlation with the power at 2.5 kg (r = 0.978). The maximum power of the lower limbs was obtained at 5.6 kg and showed the highest correlation with the power at 5 kg (r = 0.949). Thus, 2.5 and 5 kg were defined as the load intensities for the force-type power of the upper and lower limbs, respectively. The load intensities for velocity-type power were defined as 1 kg (upper) and 2 kg (lower), which were 40% of the former values. In addition, 2) upper limb power was significantly higher in WL than in BD, regardless of power type. Regarding lower limb power per body weight, no significant difference in force-type power was observed between the two groups, and velocity-type power was significantly higher in BD than in WL.
