Participants completed biweekly bench press or pull-up exercises for multiple successive weeks. Palm cooling was applied for 3 minutes between sets. Over 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 and by 80% in pull-up naïve subjects vs. 20% without cooling.
