Introduction and aim: The aim of present study was to assess the effect of six weeks Badminton training
on changes of stress and cortisol levels in non-athletic female students. Materials and Methods: In this
study estimated stress of 120 non-athlete students by stress questionnaire (HAD scale). Were measured
Among subjects who had suffered highest stress, 30 subjects with a mean age of 86/2 ± 22 years, height
56/5 ± 163 cm and weight 95/4 ± 57 kg were selected. Cortisol were measured by the bloodletting. The
subjects were divided into two experimental and control groups as homogeneous. But the control group did
not perform any activity. After training protocol variables were measured again in the same conditions. To
estimate the effect of independent variables on the dependent variable of the t-test and the independent ttest
to compare groups with a significance level (p <0/05) was used. Data were analyzed using spss and
Excel software.
Results: The results of this study showed that doing a six-week badminton practice reduces cortisol levels
(p =0.005), and decreasing stress (p =0.03) in the experimental group.
Conclusion: There was significant change in levels of cortisol and stress in experimental group.

The purpose of the current study was the effect of 8-week high intensity resistance training (the Split training method), on Testosterone, Cortisol and Testosterone/Cortisol serum level and its influence on muscle mass and development of muscle strength. 20 persons beginner in bodybuilding (body mass index: 23.80±2.25 kg/m2; age: 24.65±2.55 year) participated in this study. The subjects divided randomly into strength training (10 persons) and control groups (10 persons). Training program was designed according to the Split method with 85%-100% of 1RM for six times per weeks. The same strength and duration was applied for the control group based on the traditional training. Before and after training the thickness of Triceps muscle was measured with ultrasound in both groups. Resting blood samples were collected before and after training. The results showed, compared with traditional training, training with Split method increased muscle strength (p=0.01), muscle mass (p=0.001) and the Testosterone to Cortisol (T/C) ratio (p=0.02). Moreover, there were significant correlation between the maximum strength and hypertrophy(r=0/55, p=0/001) and between (T/C) and maximum strength (r=0/74, p=0/03). The results of this study shows that resistance training with high intensity (the Split Training Method) causes increase in anabolic stimulation and muscle mass which subsequently increases maximum strength.

This study aimed to determine the role of strength, expulsive power and range of motion of lower limb muscle on the fencing performance of elite florists. In this study, eight elite fencers’ participated. Kinetic variables measured using force plate and kinematic variable measured using motion analysis system. The squat jump test used to measure the compulsive power of the lower extremity muscles of the fencers. The Drop-jump test used to measure the lower strength of the muscles of the lower extremity muscles. Descriptive statistics (mean and standard deviation) used to describe the data and Pearson correlation coefficient used for determine the relationship between data (P≤0.05). The results of this study showed there is a significant relationship between squat jump power and mechanical energy and drop jump height with lunge speed and also between ankle range of motion with peak force and impulse in the anterior direction (P<0.05). Given the results of this study, coaches should have a special attention on the strength and explosive power of plantar flexor muscles.
