Purpose: The purpose of present study is review of effect of 8 week plyometeric, strengthens and complex (plyometeric- strengthens) exercise on agility of young free style wrestler in Ilam county. Methodology: This is semi-experiment research and its statistical community was 328 free style wrestler of Ilam County. We selected a 40 from them randomly and adminstered them by Illinois test as pre-test randomly assigned, then classified in to 4 groups, each had 10 person that: strengthens groups, plyometeric, Complex, and control. Then they performed protocol for 8 week and finally we Illinois test get them a post-test. For data analyzing, we used from dependence T-test, unilaterally variance analysis and LSD following test, and p value < 0.05 was considered significant. Results: The results show that, the 8 week strengthens, plyometeric and complex exercise have significant effect on time reduction in agility test (P<0.05). About group differences, the results of unilaterally variance analysis test show that, there is no significant difference between persons in agility test in each research groups (f=856,P=0.655). But, after 8 week exercising interference, there is no significant difference between them (f=4.48,P=0.009), the results of LSD following test show that, this had most of effect first pertaining to on complex exercise, then plyometeric and finally on strengthens exercise. Of course, there is no significant difference between complex and plyometric group and strengthens and control groups. Discussion and conclusion: with results of present study we can conclude that, for improvement of agility of wrestlers, plyometeric exercise, particularly complex exercise (plyometeric and strengthens) is more useful than the only strengthens exercise. So we suggest this kind of exercising with regard to research samples characters and entrance criterion and exit of samples in present research.
Keywords: agility, freestyle wrestler, plyometeric exercise, strengthens exercise.

The purpose of this study was to investigate the acute effects of two resistance exercise protocols with slow and fast movements on some anabolic and catabolic hormones. Hence, in a randomized crossover design, 10 healthy young men (age: 23.3±1.76 yr) divided into 3 groups: control (Con), resistance exercise with slow movement (SM), and resistance exercise with fast movement (FM). Subjects performed 6 exercises in 4 sets at 60 – 65% of 1RM. Blood sampling were taken before, immediately and 30 min after exercise. The results showed that both SM and FM significantly increased GH immediately after exercise (250 and 200 percent, respectively), but there was not any differences between SM and FM. In SM group, testosterone significantly increased immediately after exercise. SM and FM had no effect on cortisol, insulin, and glucose. It can be concluded that SM relative to FM probably has more effect on testosterone secretion.
Keywords: fast movement, GH, resistance exercise, slow movement, testosterone.

The purpose of this study was to the effects of moderate rhythm of music on perceived exertion and heart rate during different intensities of endurance training in young male athletes. 10 healthy male athletes (21.6±2.60 years), were voluntary selected and randomly divided in two groups. Data analysis showed, there was no significant difference between two stages in the warm up phase. The perceived exertion and heart rate of 60 and 70% of maximal Heart Rate under the condition of listening to music had significant decrease as compared to the condition without music (P<0.05). The perceived exertion and heart rate during exercise with the highest intensity (80% Vo2max) showed little reduction but was not significant. Finally, moderate tempo music can affect on the perceived exertion rate of training with low and moderate intensities, but it has no significant effect in the high intensity training.
Keywords: heart rate, physical activity, rate of music, rate of perceived exertion.

Increasing of c-reactive protein inflammatory indicator and lipid profiles cause to increase of probability cardiovascular disease. The influence of resistance exercise on cardiovascular diseases among females is unknown. Purpose: The aim of the project was the effects of 12 weeks of circuit exercise on c-reactive protein and lipid profiles in inactive women. Methods: 24 young inactive women, with the average of 26±3.5 years old,160±2.5cm height and 62±6.93 kg weight were selected voluntarily and divided randomly into two 12 people groups (a group as control and the other as experimental). exercise program included 12 weeks of circuit resistance exercise, 3 sessions a week with 20 to 60 minutes duration and each session on 8 stations with the 65% to 80% intensity of repetition maximum (1RM). Blood sampling was done after 14 hours of being fast just before at the beginning of the project and also after 48 hours after the last exercise session. Data were analyzed with the kolmogrov-Smirnov test (K-S test) by both dependant and independent “t-test” and the P-value of α≤0.05. Results:After 12 weeks of circuit resistance exercise in the xperimental group the amount of CRP, TG, TC, LDL-C, VLDL-C changed significantly (P≤0.05), while HDL-C did not change noticeably (P≥0.05). Conclusion: Finally, by decreasing of dangerous factors, the method of circuit resistance exercise can be considered & suggested as an effective and valuable method for preventing of cardiovascular diseases among women and improving their health.
