Asthma is a common respiratory disorder that reduces the quality of life in patients. Furthermore, due to importance of preventing and treating diseases through non-pharmacological interventions, the purpose of this research was to investigate the effect of aerobic and resistance training on physical fitness, body composition, and pulmonary function in women with asthma.

A total of 29 asthmatic women in Urmia participated in the study voluntarily with Convenience Sampling. They were randomly assigned into control group (n= 9, age= 29± 4.03 years, BMI= 23.52±2.34 kg/m2), aerobic exercise group (n= 10, age= 27.25 ± 3.10 years, BMI= 23.47 ± 3.16 kg/m2) and resistance exercise group (n= 10, age= 26.11 ± 4.83 years, BMI= 25.12 ± 2.90 kg/m2). Experimental groups exercised during 3 sessions for 8 weeks. Exercise sessions consisted of 10 minutes for warm-up, 30-40 minutes for aerobic or resistance exercises and 5-10 minutes for cool-down. Body composition and pulmonary functions were measured by caliper and spirometer and clinical signs were evaluated using Santanello’s questionnaire. Statistical analysis was conducted using independent t-test, dependent t-test, and one-way ANOVA by setting pretest as an intervening factor through SPSS-23  (p<0.05).

The results of intragroup evaluation indicated that in aerobic exercise group increased aerobic power (p = 0.02), anaerobic power (p = 0.01), flexibility (p = 0.03), muscular endurance (p = 0.02) and decreased clinical signs were significant (p = 0.01).  In resistance exercise group, increased flexibility (p = 0.00), muscular endurance (p = 0.00), and body fat percentage (p = 0.02) were significant. There was a significant increase in FVC, FEV1 / FVC and FEF75% (p <0.05) and also a significant decrease was observed in clinical signs (p = 0.05). The results of intergroup evaluation indicated that changes in flexibility, muscular endurance, and FEV1/FVC, FEF75% were significant between the exercise groups and the control group (p <0.05).

  It is concluded that both types of aerobic and resistance exercises can lead to both increased physical fitness and decreased clinical signs in women with asthma. However, the positive changes in body composition were the result of resistance exercise. Therefore, the participation of women with asthma in physical activity, especially resistance training, can improve their pulmonary function, body composition, and physical fitness.

The purpose of this study was to investigate the effectiveness of two types of resistance exercise training along with omega-3-6-9 supplementations on some risk factors of cardiovascular diseases. In this semi-experimental study, 60 healthy overweight young male students from Payame Noor University of Hamedan City were randomly assigned to 6 groups of 10 subjects, including circular resistance exercise+omega3-6-9 supplementation, progressive pyramidal resistance training+omega3-6-9 supplementation, circular resistance exercise+placebo, progressive pyramidal exercise+placebo, omega3-6-9 supplement and placebo. Exercise groups completed training programs for 12 weeks. Adiponectin levels and high-sensitivity C-reactive protein (hsCRP) were measured before and after the 12-week period of physical training. Data were analyzed using paired t test, two-way ANOVA and ANCOVA. Circular resistance exercise, but not progressive pyradimal exercise, with omega3-6-9 supplementation (P=0.000) and circular resistance exercise with placebo (P=0.007) resulted in significant increases in adiponectin levels, but not hsCRP levels. The difference between post-test mean values of the two types of exercise was significant for adiponectin, but not for hsCRP. The effect of supplementation on the level of hsCRP, independent of the type of exercise, was significant (P=0.031). There was no significant difference between the groups in relation to the hsCRP levels. Circular resistance exercise, but not progressive pyramidal, increased serum adiponectin levels independent of omega3-6-9 supplementation
