In recent years, more and more women to participate in sports. Society and schools have carried out more alternative sports for women, competitive sports these items from some low intensity, low degree of difficulty of the mass fitness classes to a high level, high strength are included.But the female itself has a periodic physiological characteristic difference between male-menstruation. During this cycle, each function will change women. Therefore, in the design of the training arrangement of women athletes, we must consider the characteristics and regularities of the menstrual cycle of female athletes, training load should be dynamic changes with the movement of the menstrual cycle rhythm consistent ability. The reasonable arrangement of the training load of women in the menstrual cycle, not only to improve exercise capacity and effect on athletes have twice the result with half the effort, to the health of women also plays a protective role, so as to avoid the training load is not suitable for female athletes of the body caused by injury.However, the research for the changes in menstrual cycle in female athletes ability just by coaches attention. Aiming at the middle distance race of literature s few, this is an important part of the middle long distance running exercise training theory are in urgent need of development.This article through the questionnaire survey method, expert interview, literature and mathematical statistics, questionnaire and interview of Beijing Sport University distance runner, and the statistics and analysis of the investigation result, draws the following conclusion.1. Beijing Sport University in 85% female runners will conduct training in the menstrual period, the 88.2% Beijing Sport University coach will make appropriate adjustments to the content and intensity of training.2. On the basis of changes in physiological function of menstrual cycle, the menstrual period of hemoglobin and red blood cells, the lowest, followed by a period of ovulation, luteal phase of the highest.3. Liu Fang blood lactate peak produce corresponding changes in the phase of the menstrual cycle, ovulation and luteal phase is lowest, global times, the menstrual period again. And after exercise blood lactic acid elimination rate of change also showed the fastest, luteal follicular phase of menstrual period, the slowest.4. Liu Fang showed a certain degree of maximal oxygen changes in each period of the menstrual cycle. The highest, the luteal phase menstrual period the lowest. Luteal phase is the female body under the best period of exercise overall athletic ability, and the menstrual period of women body load overall athletic ability are poor, the change law for Liu Fang’s training and competition arrangement for reference.5. Liu Fang’s highest serum testosterone in the luteal phase, the follicular phase of the menstrual period, the lowest. |
