  • Abstract

The purpose of this study was to investigate the effect of wearing tights on performance while pedalling at high intensity. Eight male undergraduates majored in sports science volunteered to participate in the experiments. Subjects wearing Gradient Compression Tights (GCT) or loose pants as control condition (CONT), pedalled on the power bicycle-ergometer at 180W/60RPM till exhaustion. Surface EMG was recorded at the surface of Rectus Femoris (RF), Vastus Lateralis (VL), Biceps Femoris (BF) belly, Tibialis Anterior (TA) belly and Medial Gastrocnemius (GM) and the heart rate was also monitored. It was confirmed that the GCT exerted gradient pressure distribution on the surface of lower limbs. Such gradient pressure helped to increase the venous return and the heart output, resulted in relatively lower heart rate and longer pedalling duration. The EMG analysis showed significant effect on the average EMG (aEMG) and the Mean Power Frequency (MPF) caused by GCT. Based on a pattern of motor recruitment with the recurrent inhibition, it was speculated that the pressure might enhance the activity of inhibition interneurones, more Motor Units (MU) of low thresholds were inhibited. Due to the less contribution of low-frequency components, the aEMG was lower and the MPF was higher.
