In this study, we examined the effects of elastic wrist taping with different pressure levels on the maximum grip strength. The subjects were 20 healthy male university students. The tape was wrapped three times around the wrist at the radial and ulnar styloid process. Taping pressure was measured using a pressure measuring system for stockings and bandages. A pressure sensor was placed over the palmaris longus muscle tendon, 1.5 cm proximal to the palmar crease of the subject’s wrist on the dominant upper limb. The following experimental conditions were assessed: control condition (CC), without attachments; sensor condition (SC), with an attached sensor and a cover tape with minimum pressure application (1–5 hPa); and four pressure conditions (PCs), with pressure applications of 30, 60, 90, and 120 hPa using elastic tapes. Grip strength was significantly greater for CC than for PCs. However, the overall decrease in grip strength was still relatively small. No differences were observed in the grip strengths among the four PC groups. Our results showed that grip strength exertion decreased on the application of higher pressures of elastic tape wrapping and that the degree of decrease was similar for all PCs above 30 hPa.
