Abstract
Background and Objectives: It has been shown that low intensity physical activity rarely increases bone density or renewal. Therefore, the purpose of this study was to investigate effects of four weeks of plyometric training with and without vascular occlusion on serum levels of bone alkaline phosphatase (BALP) and C-terminal telopeptide of type I collagen (CTX), as markers of bone formation and bone degeneration in inactive girls.
Methods: This was a semi-experimental study with a pretest-posttest design. The study population consisted 36 inactive female students aged 23.84±1.096 years with a mean body mass index of 22.59±0.52 kg/m2 who were randomly divided into a plyometric training group without blood flow restriction, a plyometric training group with blood flow restriction and a control group. The experimental groups performed four weeks of plyometric training (three sessions per week), while the control group did not perform any exercise. Blood samples were obtained 48 hours before the first training session and 48 hours after the last training session. Measurement of BALP and CTX was carried out using commercial enzyme-linked immunosorbent assay kits. Collected data were analyzed using t-test and one-way analysis of variance. All statistical analyses were performed using SPSS software (version 23) and at significance level of ≤ 0.05.
Results: The level of BALP was significantly higher in the low intensity exercise with blood flow restriction group compared to the control group (P=0.005) and the low intensity exercise group without blood flow restriction (P=0.003). The BALP/CTX ratio, as marker of bone metabolism, increased significantly following low intensity exercise with blood flow restriction compared with the other groups (P<0.05). However, low intensity exercise without blood flow restriction induced no significant change in the studied indices.
Conclusion: Plyometric training with blood flow restriction could be as effective as high intensity training for improving bone metabolism and turnover, particularly in inactive individuals.

Abstract
Background and objectives: The prevalence of obesity and overweight in women is increasing. Secretion of adipokines such as vaspin may affect insulin sensitivity. It has been suggested that physical activity can alter circulating vaspin levels. The purpose of this study was to investigate effects of six weeks of aerobic interval training on serum vaspin and blood glucose levels in obese inactive girls.
Methods: In this quasi-experimental study, 22 inactive overweight girls were selected from the Shahid Chamran University of Ahvaz, Iran. The mean age, weight and body mass index of the subjects were 24.22±1.35 years, 83.77±12.66 kg and 32.56±3.36 kg/m2, respectively. The subjects were randomly divided into an experimental group )n=11) and a control group )n=11). The experimental group performed aerobic training on stationary bicycle at 65-80% of maximal strength, three sessions a week for six weeks. Serum levels of vaspin and glucose were measured using commercial kits. Data were analyzed using SPSS (version 23) and at significance of 0.05.
Results: The training intervention had no significant impact on the serum vaspin and glucose concentrations (P>0.05). In addition, the covariance analysis showed that serum vaspin and glucose levels did not differ significantly between the study groups (P>0.05).
Conclusion: Based on the results, the six-week aerobic interval training had no significant effect on vaspin and blood glucose levels of inactive obese girls. It is recommended to further examine the effect of this type of exercise at higher intensities and for longer durations.

Abstract
Background and objectives: As a chronic inflammatory airway disease, asthma can increase level of markers of inflammation and muscle damage. In this study, we aimed to evaluate the effects of short-term continuous aerobic exercise combined with vitamin D supplementation on high-sensitivity C-reactive protein (hs-CRP), lactate dehydrogenase (LDH) and creatine kinase (CK) levels in asthmatic women.
Methods: In this study, 30 overweight (body mass index=26.97± 1.24 kg/m2) women with mild to moderate asthma were purposefully selected.. The subjects received a vitamin D tablet with a daily dose of 1000 IU for six weeks. The training protocol consisted of two sessions of Balke treadmill test (one session before and one session after the vitamin D supplementation). Blood samples were taken before and immediately after the exercise and before and after vitamin D supplementation. Repeated measures ANOVA was used to evaluate changes in the levels of hs-CRP, CK and LDH.
Results: The variables were not significantly affected by the exercise and vitamin D supplementation (P>0.05).
Conclusion: It seems that a single session of short-term aerobic exercise and six weeks of vitamin D supplementation do not significantly affect hs-CRP, CK and LDH levels in asthmatic women.
