Participants completed biweekly bench press or pull-up exercises for multiple successive weeks. Palm cooling was applied for 3 minutes between sets. The temperature of the cooling device was 15-16 degrees Celsius (59-61 degrees Fahrenheit). After 3 weeks of bench press training, palm cooling increased work volume by 40% vs. 13% without cooling.
Over 6 weeks of pull-up training, palm cooling increased work volume by 144% in pull-up experienced subjects vs. 5% without cooling. Pull-up volume in non-experienced participant improved by 80% with cooling vs. 20% without cooling.
This study demonstrates a strong relationship between cooling and improved training volume compared to non cooling. This effect was shown in both people new to exercise and those who were experienced.
