Improved sweat gland function during active heating in tennis athletes.

摘要: Abstract Background Relatively few studies on the peripheral sweating mechanisms of trained tennis athletes have been conducted. The purpose this study was to compare capacities against untrained subjects (controls). Methods Thirty-five healthy male volunteers participated including 15 and 20 (nationally ranked). Active heat generation performed for 30 min (running at 60% VO 2 max ) in a climate chamber (temperature, 25.0°C ± 0.5°C; relative humidity, 60% ± 3%, termed active heating). Sweating data (local sweat onset time, local volume, activated glands, output per gland, whole body loss volume) were measured by capacitance hygrometer-ventilated capsule method starch-iodide paper. Mean temperature calculated from tympanic skin temperatures. Results Local time shorter ( p  0.001). glands torso limbs, volume significantly higher than control after heating Tympanic mean temperatures lower among controls 0.05). Conclusion These results indicate that had increased regulatory capacity their gland function.
