Abstract: Angela Schuh Institute of Medical Balneology and Climatology University of Munich München Germany ABSTRACT. Several studies documented an immediate reaction of heart rate during physical work under the influence of cold. But there has yet no research been done on the phenomenon of the immediate reaction on the aerobic muscle metabolism under these conditions. About a relationship between the process of a developing state of endurance training under simultaneous exposure to cold in the sense of a cross adaptation or an additive effect no relevant studies can be found in the literature. So far no author could point out whether the adaptation to a cool environment during endurance training goes along with an increased efficacy. The goal of this study was to quantify the improvement of aerobic performance by endurance training with and without cooling of body shell. To do this terrain training lasting three weeks is conducted: with one group of the test subjects (n = 63) the body shell was kept defined cool during the training; the skin temperature was lowered by 2°C. The control group (n = 61) did a terrain training under thermally balanced conditions. The actual aerobic fitness and the effect of endurance training under thermal conditions was evaluated using ergometric tests taken at the beginning and at the end of the therapy. The results showed that reduced skin temperatue during work has two effects on the muscle metabolism: (a) As an ...
