Sports Participation Status and Sports Demand of Disabled Adolescents Aged Six to 15 Years in Henan / 中国康复理论与实践

Objective To analyze the status of sports participation and the demands of physical activity for people with disabilities aged six to 15 years. Methods According to the results of National Disabled Basic Service Condition and Demand Special Survey,71,056 ad-olescents with disabilities aged six to 15 years were analyzed. Results People who often took part in sports activities only accounted for 1.6%, there was no significant difference among different types and different levels of disability(P>0.05).The physical activity demand of people with dis-abilities aged six to 15 years reflected in scientific physical activity knowledge,suitable sports projects,adequate facilities,and professional rehabilitation sports guidance. Conclusion The sports participation situation needs to be improved in people with disabilities aged six to 15 years in Henan.The demands of rehabilitation sports for people with disabilities from multiple aspects should be met.

Dynamic changes of cardiovascular regulating factors in rats after aerobic exhaustive exercise / 中国应用生理学杂志

<p><b>OBJECTIVE</b>To study the changes of cardiovascular regulating factors in rats during recovery of aerobic exhaustive exercise.</p><p><b>METHODS</b>Sixty male Wistar rats were randomly divided into control group, 1 h-exercise group, 3 h-exercise group, exhausted group, 2 h-recovery group and 12 h-recovery group. The rats were killed at corresponding times for each group after an 8-week-long treadmill training, and the levels of NO, ET, ANP and TXB2 in plasma were measured in each group.</p><p><b>RESULTS</b>NO/ET ratio of 1 h-exercise group was significantly higher than that in control group (P < 0.01), while it was significantly decreased in 3 h-exercise group and exhausted group (P < 0.05). ANP contents in rat plasma were significantly higher in 3 h-exercise group, exhausted group and 2 h-recovery group than that in control group (P < 0.05 or P < 0.01). The concentration of TXB2 in plasma was significantly increased in 3 h-exercise group, exhausted group and 2 h-recovery group (P < 0.05).</p><p><b>CONCLUSION</b>Changes in cardiovascular regulating factors after exhaustive exercise may lead to deficiency of coronary circulation blood/oxygen supply, which may cause exercise-induced fatigue.</p>

Effects of the compound extract of Chinese medicine on free radical metabolism of the rat brain in different states / 中国应用生理学杂志

<p><b>OBJECTIVE</b>To investigate the effect of the "compound extract of Chinese medicine" on free radical metabolism and antioxidant enzyme systems of the rat brain.</p><p><b>METHODS</b>70 Wistar mice were randomly divided into two groups (n = 35): normal control group (N), taking medicine group (M). After a week of feeding, M group was taking medicine for 8 weeks. After 9 weeks, killed the two groups when they were at the rest state, the immediate ends of the fixed load, the immediate ends of exhaustive exercise and 12, 24 hour ends of exhaustive exercise, respectively. And the activity of malonaldehyde (MDA), glutathione peroxidase (GSH-PX), glutathione (GSH), superoxide dismutase (SOD), total anti oxidation capacity (T-AOC) of the rat brain were measured.</p><p><b>RESULTS</b>At the five states, the content of MDA in M group was lower than that in N group in different degree, the activity of GSH-PX, GSH, SOD, T-AOC in M group were higher than those in N group in different degree.</p><p><b>CONCLUSION</b>The "Compound extract of Chinese medicine" can reduce the MDA level of the rat brain and improve the enzyme activity of GSH-PX, GSH, SOD, T-AOC.</p>

Different strength intermittent treadmill training of growth period rats and related bone metabolism of the hormone influence / 中国应用生理学杂志

<p><b>OBJECTIVE</b>To explore the influence of different strength intermittent treadmill training of growth period rats on the bone metabolism, so as to provide the training intensity of teenagers to set theory support.</p><p><b>METHODS</b>Select 70 male four weeks Wistar rats according to body weight randomly divided into seven groups (n = 10): the control group and the exercise group. According to the VO2max the exercise group was divided into 6 groups: 65%, 70%, 75%, 80%, 85% and 90% group. Nine weeks treadmill training, training six days a week, each group of training three times, each time not less than 10min, the interval was 30 min. The last movement after 24 h, took the femur and blood to measured the bone mineral density (BMD), bone mass (BMC) and alkaline phosphatase (AKP), resist tartaric acid acidic phosphatase (Str-ACP).</p><p><b>RESULTS</b>1. The femoral BMD (0.1393 +/- 0.0031), BMC (0.4525 +/- 0.0335) of 70% group were significantly higher than those in the control group (BMD: 0.1200 +/- 0.0095, BMC: 0.3238 +/- 0.0485) and the other sports group (65% BMD:0.1339 +/- 0.0062, BMC: 0.4058 +/- 0.0492, 75% BMD: 0.1296 +/- 0.0015, BMC: 0.3869 +/- 0.0254, 80% BMD: 0.1223 +/- 0.0082, BMC: 0.3454 +/- 0.0483, 85% BMD: 0.1250 +/- 0.0044, BMC: 0.3731 +/- 0.0381, 90% BMD: 0.1171 +/- 0.0047, BMC: 0.3051 +/- 0.0286) (P < 0.05), the femoral BMD, BMC of 90% group were lower than those of the control group, the other in the exercise group were higher than those in the control group; 2. Serum AKP in the exercise group were significantly higher than those in the control group, the group of 65% (41.015 +/- 2.114), 70% (46.035 +/- 2.611), 75% (43.834 +/- 3.155), and 80% (38.043 +/- 4.073) were very significantly higher than those in the control group (26.875 +/- 1.188) (P < 0.01); 70% group and 75% group were significantly higher than those in the 80% group , 85% group and 90% group, while 70% group serum AKP level were significantly higher than those in 65% group (P < 0.05), it showed that 70% of the VO2 max training intensity of osteoblasts was most active. The serum Str-ACP of exercise group were significantly higher than those in the control group, along with the increase of the training intensity, serum Str-ACP level was rising and the group of 80% (22.430 +/- 1.591), 85% (23.990 +/- 1.870), and 90% (28.009 +/- 1.839) serum of Str-ACP were significantly higher than those in the group of 65% (18.503 +/- 2.429), 70% (16.447 +/- 2.120) and 75%(17.769 +/- 1.642) ( P < 0.05), the group of 90% serum Str-ACP were significantly higher than those in the group of 80% and 85% (P < 0.05).</p><p><b>CONCLUSION</b>The training of 70% of the VO2max, moderate intensity intermittent running, make the growth period rat bone mass and bone mineral density to increase obviously.</p>

Effects of Chinese herbal compound on monoamine and neuronal amino acids in rat's telencephalon in the course of exhaustion and recovery process / 中国应用生理学杂志

<p><b>OBJECTIVE</b>To observe the effect of Chinese herbal compound on variance of neurotransmitters in rat telencephalon and to further discuss the mechanism underlying Chinese herbal compound in improving exercise capacity and promoting recovery from exercise-induced fatigue.</p><p><b>METHODS</b>64 rats (8 week old) were randomly divided into medicine group (MG) and control group (CG). Chinese herbal compound was administered to rats of MG for 8 weeks. 8 weeks later, every group was divided into 4 subgroups and all were killed at different time point separately, and then neurotransmitter in rat brain was tested.</p><p><b>RESULTS</b>The exhaustion time of MG was significantly longer than that in CG (P < 0.01). In rest conditions, glutamic acid (GLU) of MG was significantly higher than that in CG (P < 0.01), while, there were no significant differences between MG and CG in other indexes. After fixed quantitative load exercise, the content of 5-hydroxytryptamineZZ(5-HT), 5-hydroindole acetic (5-HIAA), gamma-aminobutyric acid (GABA), Dopamine (DA) and 5-HT/5-HIAA were significantly lower than those in CG, while, GLU, GLU/GABA and DA/5-HT were significantly higher than those in CG. Compared with CG, exhaustion significantly (P < 0.05) decreased 5-HT, GABA and 5-HT/5-HIAA, and significantly (P<0.05) increased GLU, DA/5-HT and GLU/GABA level in MG. 12 h after exhaustion, in contrast to CG, level of 5-HT and 5-HT/5-HIAA in MG were significantly (P < 0.01) lower while GLU, DA, GABA and DA/5-HT were significantly (P < 0.01) higher.</p><p><b>CONCLUSION</b>During exhaustion exercise, Chinese herbal compound demonstrated strong inhibiting effect on synthesis of 5-HT, 5-HIAA, DA, GABA and promoting effect on GLU synthesis, this had been confirmed by the combined effect, including increase of excitatory transmitter and excitability of central nervous system and the prolongation of exhaustion time and promoting recovery from fatigue.</p>
