CHANGES IN FINGER COLD-INDUCED VASODILATION BETWEEN SKI-AND PHYSICAL-TRAINING

Abstract

The present study aimed to examine the change cold-induced vasodilation (CIVD) of finger between seven female alpine (AP group) and six female cross-country skiers (CC group) at different points in their training programs. The CIVD test was performed twice, once in spring period after ski-training, once in the summer period during physical-training. From the onset of ice-water immersion in each CIVD test, finger skin temperature in each group fell followed by an incline. Thereafter, finger skin temperature began to rise and fall in an attenuated fashion during ice-water immersion. The resistance index (RI) in summer (7.1±1.7) for AP group was significantly (P<0.01) higher than that in spring (4.6±1.1). However, that of CC group showed no difference between spring and summer. These results suggested that the physical training during summer period for AP group may influence on the improvement of CIVD.
