Heart Rate Characteristics for Male Chinese College Students of Different PA-Level during 3000 Meters Running

Abstract

PUPPOSE:To explore the Heart Rate load variation for male Chinese college students of different physical activity level during 3000 meters running, providing a reference for training load monitoring and security. METHODS: Real-time heart rate of 475 Chinese undergraduate students in Tsinghua University were test with Team 2 Polar tester during 3000-meter-run test. The physical activity was investigated by an international questionnaire. All subjects were grouped three by PA levels. Data calculated by SPSS 20.0. RESULTS: 1. There were significant difference in heart rate among students with different levels of physical activity during 3000-meter-run. The mean of maximum heart rate in group with lower PA level was the highest 202.4±8.9, while that of the group with good PA level was the lowest 198.7±6.4(P<0.05). 2. The heart rate has relation to the time during 3000-meter-run. The average speed of first three laps has a significant linear relationship to the average heart rate(R=0.875). The heart rate reached a plateau in the last four laps. The heart rate of all reached the maximum in the end of test. 3. The maximum heart rate of 20% individual students reached or exceeded the summit value of maximum heart rate (220-age), and continued for a several minutes within a relatively dangerous range. CONCLUSIONS:Mean of maximum and average heart rate of Chinese male college students with good PA level group was lower than that of poor PA level group in 3000-meter-run test. There is a high risk factor for poor PA level Chinese male students when running continuously in the maximum heart rate level. Study was supported by The Chinese General Administration of sports (2015B075)Fig. 1: Mean of heart rate for different PA levels during 3000 meter running
