A whole-body compression garment (WBCG) is mainly used for cosmetic purpose in Korea. Another case for wearing the WBCG would be while exercising because it allows the body to move easily. But physiological effects of wearing WBCG to the body have not been known much. To investigate whether wearing WBCG would be helpful for conducting exercises, we measured physiological criteria, which could be influenced by the compression, such as cardiovascular and pulmonary function. Twelve female college students participated in this experiment. Increase of blood pressure was monitored in all of the participants when they wore a WBCG just for 10 minutes. Pulmonary function that requires skeletal muscle contraction was decreased by wearing a WBCG. Blood pressure measured after conducting exercise became even lower when wearing a WBCG than non-wearing. Interestingly, heart pulse remained lower when wearing a WBCG than non-wearing during the whole relaxing period after the exercise. Electrocardiogram (ECG) analyses showed that such lower heart rate largely depended on extension of QT time. For that reason, physiological efficiency index (PEI) was higher for wearing WBCG. These results indicate wearing WBCG could enhance exercise efficiency by lowering heart pulse.
