Abstract
As an index of bodily adaptation development for muscular exercise two groups of subjects (T-group, trained, and U-group, untrained) were studied under a fixed environmental condition. All the member of T-group responded with quicker rises in the sweat rate, as if their bodies anticipated and took measures against the impending rise of body temperature, and attained early at the individual steady levels, in moderate or low load exercise ; moreover their Cl losses in the sweat were remarkably low, thus effectively keeping the internal environment of the body (this time the ion concentration of the blood) less disturbed. Together with other findings, we infer that physical training sets our body more efficient in dealing with the excessive heat produced by muscular exertion.
