Exercise modes can be divided into open skill exercise and closed skill exercise. Also, different types of exercise have different effects on factors related to improving cognitive function. Therefore, the aim of this study was to investigate the effect of a judo training session (open skill) and a weight training session (closed skill) on serum levels of NGF and FGF-2 in female judokas.

In this quasi-experimental study, 11 female judokas (age: 25.60±3.57 years, weight: 66.20±9.60 kg, height: 165.40 ± 4.50 cm) voluntarily participated. Subjects participated in two sessions of judo and weight training for one hour 10 days apart. Blood samples were taken from the subjects five minutes before and after each training session. Serum levels of NGF and FGF-2 were measured by ELISA. Data analysis was performed by one-way ANOVA with repeated measures at the significance level of p<0.05.

The results of one-way ANOVA with repeated measures showed that the serum levels of both NGF and FGF-2 variables increased significantly after both types of training (p<0.05). Also, serum levels of FGF-2 after weight training increased significantly more than judo training (p=0.001). However, changes in serum levels of NGF was the same after both training sessions (p=0.39).

It seems that weight training and judo training have different effects on serum levels of FGF-2. Therefore, the mechanism of the effect of judo training and weight training on cognitive function may be different. Therefore, it is recommended to use different exercises to further improve cognitive function.

The aim of this study was to investigate the effect of 8 months of resistance training on GH, IGF1 and plasma insulin levels of patients with severe burns. The research method used was the case study with multiple base-lines for participants. The participants included two women with severe burns (age range of 20-30 years) in the “Accidents and Burns Hospital”. After determining the baseline, participants performed resistance training during 8 months of individual intervention and one month after this period, they were put under follow-up examinations for 2 consecutive months. The blood samples were collected under the fasting condition 24 hours after training at the end of each month. Based on the visual analysis, the resistance training in both participants caused changes (PND = 75% for the first participant in GH and 87.5% for the second participant, PND = 100% for both participants in IGF1 and PND = 62.5% for the first participant in insulin and 50% for the second participant). It seems that long-term resistance training can improve hormones and growth factor in patients with severe burns and consequently can expedite the treatment of the burns.

This study was conducted to determine the growth factors response to two weeks of detraining after a physical activity program in short stature children. 14 children with idiopathic short stature were selected as the sample of the study. Physical activity program consisted of activities and sport games suitable for children. Simultaneously, children in the control group participated in a drawing course. The intensity of physical activity was controlled in the range of 40-60% of maximum heart rate. IGF-I and IGFBP-3 levels were measured at baseline, after 8 weeks of training and after 2 weeks of detraining. The results showed small but not significant changes in IGF-I and IGFBP-3 after 2 weeks of detraining in the experimental group while they significantly increased in the control group (P
