This paper discusses the problem of one-time Incremental Exercise to Exhaustion and before and after the recovery period subjects serum NO content and NOS activity in The study used a combination of movement experiments and biochemical analysis method , a random sample of Shanxi University, Department of Physical Education ( hereinafter referred to as the experimental group) and the general system ( hereinafter referred to as the control group ) students in each of the 15 as the object of study , the production of Sensormedics2900 in the United States cardiopulmonary functional instrument 50w strength starting point , every 3min the 50w movement to exhaustion , inhaled and exhaled gases collected for analysis , and the resulting data are used SPSS10.0 statistical software . The results showed that the experimental group , maximal oxygen uptake , power and movement time than the control group ( P <0.01 ) . Pre-exercise resting state , the experimental serum NO level higher than that of the control group (P <0.01). After exhaustive exercise , NO and NOS in the variation in the serum of the control group and the experimental group are basically the same , that the variation of the NO is then increased first and then decreased , NOS on first down , and the variation between the two indicators in experimental group showing a very significant negative correlation ( P <0.05 ) . Accordingly , we believe that : first , a one-time incremental load to exhaustion after exercise , physiological changes in the experimental group control group , and biochemical indicators of recovery in the experimental group than the control group after exhaustive exercise faster , which to some extent indicated on the physical fitness of the subjects of the experimental group is better than the control group may be due to one hand, thanks to the long-term physical exercise , on the other hand , may be related to genetic factors . Second, the variation of the serum NO content and NOS activity is not fully rendered consistency. The same trend in the long-term persistence of physical exercise , but in a one-time incremental Exercise to Exhaustion , showing a negative correlation , suggesting that the NO content in addition to the body by the NOS activity constraints may also be affected by other factors impact. Third, by the movement in the form of changes in the concentration of plasma NO can be seen in patients with cardiovascular disease should not take disposable exhaustive exercise movement , while the long-term , the mild aerobic exercise is the best form of exercise .
