Abstract:
BACKGROUND:Generaly, higher transcutaneous oxygen pressure indicates stronger aerobic fitness. Decreased transcutaneous oxygen pressure and increased transcutaneous carbon dioxide pressure reflect severe fatigue, muscle hypoxia, and poor function state.
OBJECTIVE:To observe changes in transcutaneous oxygen pressure and transcutaneous carbon dioxide pressure in biceps brachi of excelent male rowing athletes during 6-week altitude training, and analyze relationship of the changes to training load.
METHODS:The training containsthreestages,i.e., before, during and after altitude training. Transcutaneous oxygen pressure and transcutaneous carbon dioxide pressure were determined using PeriFlux System 5000 laser Doppler flowmetryin athletesintheresting-fasting state in the morning. Lactic acid level in athletes was determined using 6-grade load test 1 week before altitude training and 2 weeks after the end of altitude training.
RESULTS AND CONCLUSION:Transcutaneous oxygen pressure and theratio of transcutaneous oxygen pressure to transcutaneous carbon dioxide pressure showed the W-shape change, and transcutaneous carbon dioxide pressure showed the V-shape change. These results suggest that the arrangement of the altitude training program is suitable, namely“reserve physical fitness at the plain stage, add amount and enhance degrees of altitude training load at the early and late stages”,andit can provide a better training load structure model for the post-altitude training. Transcutaneous oxygen pressure and transcutaneous carbon dioxide pressure, in particular the ratio of them,canbeused to evaluate the degree of exercise load that athletes receive. At the same time, capilaries oxygen can be quantified by testing transcutaneous oxygen pressure.Transcutaneous oxygen pressureis recommendedas a noninvasive index to monitor changes in aerobic capacity of athletes.
