The aim of this study is to investigate the effect of short-term icing of the forearm muscle group between exercises on the grip endurance of judo athletes. The participants were eight female university judo athletes (mean age: 21.3±3.1 years). Grip endurance was evaluated through an exercise task by attaching weighted “Uchi Komi Straps” to the forearms of the judo athletes, and then measuring the gripping time (all-out time). The exercise task was performed twice with a 5-minute rest period between the two sets. During the rest period, four intervention conditions were performed: icing, stretching, icing and stretching, and rest only (control). In addition to measuring the all-out time during the exercise task, maximum grip strength, rate of force development during gripping, skin temperature of the forearm, and subjective feeling of fatigue in the forearm were also measured before and after the tasks. Blood flow through the flexor muscle group of the forearm after the intervention was also measured and compared with the blood flow at rest. The results revealed a reciprocal action in the all-out time during the two sets of the exercise task, and in the second exercise task the two conditions that included icing significantly suppressed the all-out time reduction compared to the control condition. While there were no significant interactions between the four conditions and maximum grip strength, the rate of force development during gripping was not adversely affected by icing. There were no significant differences in the blood flow of the forearm flexor muscle group among the different intervention conditions. These results suggest that it may be possible to prevent a reduction in the grip endurance of judo athletes by icing the forearm muscles for a short period of time between exercises or by using a combination of stretching and a short period of icing.
