ABSTRACT
Capacitive and resistive electric transfer (CRET) therapy can improve flexibility and increase muscle activity and may be useful as a warm-up technique. This study examined the effects of short-time CRET on jump performance. Thirty healthy men (age range, 20-40 years) were randomly divided into passive (n = 15) and active (n = 15) warm-up groups. The participants and statisticians were blinded to the participant allocation. The passive warm-up group underwent 4 min of CRET therapy on their posterior lower legs. The active warm-up group performed stretching and jogging for 4 min. Calf muscle temperature and rebound jump (RJ) index were measured before and after the intervention. The mean (± standard deviation) muscle temperature increased by 2.0 ± 0.5°C and 1.4 ± 0.6°C in the passive and active warm-up groups, respectively (p < 0.05). RJ index increased significantly in both groups (p < 0.05). Therefore, passive warm-up using CRET may help avoid energy loss while increasing the muscle temperature in a short time when compared with traditional active warm-up techniques.
Capacitive and resistive electric transfer (CRET) is a device with deep thermal effect. CRET therapy can improve flexibility and increase muscle activity and may be useful as a warm-up technique. This study examined the effects of short-time CRET on jump performance. Thirty healthy men (age range, 2040 years) were randomly divided into passive (n=15) and active (n=15) warm-up groups. The passive warm-up group underwent 4min of CRET therapy on their calf. The active warm-up group performed stretching and jogging for 4min. Calf muscle temperature and jump performance were measured before and after the intervention. The mean (± standard deviation) muscle temperature increased by 2.0±0.5°C and 1.4±0.6°C in the passive and active warm-up groups, respectively (p<0.05). Jump performance increased significantly in both groups (p<0.05). Therefore, passive warm-up using CRET may help avoid energy loss while increasing the muscle temperature in a short time when compared with traditional active warm-up techniques.
