Abstract

Research purposes: in the experiment of simulated high temperature and high humidity environment, by using four methods of precooling (oral ice slurry + ice vest, vest, oral ice slurry control), compare the four methods of precooling under high temperature and high humidity environment impact on the power bicycle sports ability of athletes. Methods: four subjects postprandial 2 h into the lab, after quiet rest 15min start the test of basic value. Then intervene precooling of four subjects in turn, each participant completed the experimental intervention order is the same, the first control group - ice vest - oral ice slurry group - joint precooling group, precooling time is 30 min. after precooling immediately determinate relevant indicators, then immediately into the simulation of high temperature and high wet lab for increasing load of power cycling, the movement began power is 60W, each 5min increase 40W, until exhausted, every 5min acquisition related indexes in the process of movement. The results of the study: 1 in terms of the power cycling test distance, combination of cooling jacketand ice injestion(J+V) using oral ice slurry precooling (O)measures compared with control group(C), there are significant differences (p < 0.05);Ice vest(I) compared with C (p < 0.05) there are significant differences; J+V precooling compared with C group, (p < 0.01) has a very significant difference; J+V precooling compared with I (p < 0.05), there is significant difference.2 before and after oral ice slurry precooling the body's core temperature (p < 0.01) has a very significant difference; Joint precooling group of core body temperature (p < 0.01) has a very significant difference; Research conclusion: under the condition of high temperature and high humidity three precooling measures all make the cyclist in power cycling sport ability improved, combination of oral ice slurry + ice vest precooling method to improve the sports ability of cyclist is superior to the separate use of oral ice slurry precooling measures , ice vest precooling mechanism is characterized the core of lower body temperature, heart rate, blood flow perfusion index, increase body heat reserve capacity, but heat reserve capacity increases related to the influence of brain activity, neurohumoral factors, the cardiovascular and metabolic needs further research.
