| College football is football an important part of development, with the recent increase in the domestic league college students, the college sport, football and more the subject of attention, therefore, understand the characteristics of their own college football team, student team members to improve physical fitness, and continuously Improving competition level is very important. July 2006, Taiyuan University of Technology football team in Shenyang at the "Li Ning Cup" China University Football League record with impressive win for the province's first national tournament runner-up, made a historic breakthrough. Taiyuan University of Technology as a captain, I played for my school for many years and witnessed the growth of our school football team. In 2006 after the league, although I have also made impressive team record, but it is difficult beyond the 06 glory. Winning team that year as the Beijing Institute of a documentary news network report gave away my school football team in the first half when the final stage of physical strength has begun to fall. Over the years, I found that by summing up after the game, most of my school football team players have played for professional teams in China, technical and tactical teams to win no less than previous years. But the overall is not very balanced physically, in particular, accidental injury or tactical Players need to end, after playing second string this physical difference is particularly important. The topics on our school football team to study the status of heart and lung function compared with non-main difference between the main players in order to narrow the search for better methods of training between the two physical differences in, for the team replaced old ones, raise the level of provision of physical theory.In this paper, the Italian subjects of step (COSMED) produced quarkb 2 Cardiopulmonary Exercise Testing Instrument and the accompanying power bike (E 100K type) of the Taiyuan University of Technology men's soccer team to conduct 24 experiments, and draw conclusions.1. exercise capacity, the Taiyuan University of Technology Men's Soccer Players in the sub-maximum load and maximum load capacity is higher than when the movement of substitutes.2. ventilation and breathing pattern, the anaerobic threshold (VT), the main force of Taiyuan University of Technology and the substitutes minute ventilation (VE) were 112.8±31.8L/min, 74.4±32.8 L / min, through statistical Comparison of a very significant difference. When the maximum oxygen uptake and Taiyuan University of Technology main substitutes of ventilation and breathing consistent. 3. cardiac function in the movement subjects to ventilatory threshold (VT), the main Bo oxygen intake for each team is stronger than substitutes, the major players in the cardiac function better than substitutes. In maximal oxygen uptake VO2max, the two players heart rate were statistically no significant difference test, indicating that maximum load stage, two members of the cardiac function fairly.4. the movement of gas exchange, and energy metabolism was found after comparison: substitutes anaerobic function earlier than the main players were, in the relatively low oxygen uptake, the oxygen utilization is not high. Players of the maximum oxygen intake than substitutes. In this study, Taiyuan University of Technology men's soccer team in the leading player in the respiratory quotient was significantly lower than substitutes. Players team and substitutes that in unit time compared to larger oxygen uptake, exercise ability.
