“…Based on the obtained results, only in the aerobic exercise group, the maximum oxygen consumption significantly increased. These results are consistent with the findings of Motamedi et al [29]. However, they are in contrast with the findings of Gelecek et al [30].…”

Purpose: Osteoarthritis is a frequent complication in the middle-aged or older people. Besides pain and swelling, this disease causes deformity and difficulty in walking. The current study compared the effects of 12 weeks bariatric and aerobic exercises on the metabolic syndrome in women with knee osteoarthritis. Methods: In this quasi-experimental study, 24 women with knee osteoarthritis were selected by convenience sampling method. They were randomly divided into two groups of the bariatric (n=12) and aerobic (n=12) exercises. The training included aerobic and bariatric exercises at 60%-65% rate of the heart rate reserve. The program included a 12-week training, performed three times per week and each session lasted for 30 to 60 minutes. Intra-and inter-group comparisons were performed by dependent t-test and Analysis of Covariance (ANCOVA), respectively. The level of significance was set at P<0.05. Results: In both the aerobic and bariatric groups, 12 weeks of exercise program resulted in a significant reduction in weight, body mass index, serum glucose, insulin level, and insulin resistance index. Only in the aerobic exercise group, the concentrations of high-density lipoprotein, low-density lipoprotein, and total cholesterol significantly increased and decreased, respectively. The levels of triglyceride significantly decreased in both groups. Only in the aerobic exercise group, the maximum amount of oxygen consumption was significantly increased. Conclusion: In women with knee osteoarthritis, 12 weeks of aerobic and bariatric exercises positively affect the levels of insulin resistance markers, lipid profiles, and max-oxygen consumption. Therefore, these two exercise programs can be used to maintain health of these people.

“…The present study showed that aerobic and resistance training for eight weeks increased VO2max. These results are consistent with the findings of Motamedi et al [26]. Motamedi et al examined the effect of a diet with or without aerobic exercise on anthropometric indices and cardiorespiratory fitness of men aged 25 to 50 years, concluding that eight weeks of aerobic exercise, three sessions per week, with an intensity of 55 to 60 % HRR, comprising brisk walking, jogging, and a combination of simple aerobic steps, increased VO2max levels at the end of the period.…”

Introduction. Studies have revealed that the anabolic effect of irisin on bone is mediated by an increase in alkaline phosphatase. However, few studies have investigated the interactive effect of irisin on alkaline phosphatase after exercise training. Therefore, the present study aimed to compare the impact of endurance and resistance training protocols on serum irisin concentration and total alkaline phosphatase activity in sedentary obese women. Material and methods. Forty-five sedentary obese women (age: 48.96 ± 5.2 years, body mass index 32.24 ± 3.76 kg/m2) were randomly assigned to control, endurance, and resistance groups. Endurance (45 to 75 minutes at an intensity corresponding to 50 to 80% of heart rate reserve) and resistance exercise training (3 sets, 10-15 repetitions at an intensity corresponding to 50 to 65% of one-repetition maximum) were conducted for 8 weeks, 3 days per week. Maximal oxygen consumption (VO2max) was estimated using the modified Bruce protocol treadmill test. Fasting blood samples were taken before the first and 48-hr after the last exercise training sessions. The serum concentrations of irisin and total alkaline phosphatase activity were measured using the sandwich ELISA method and photo-metric method, respectively. Results. Both endurance and resistance exercise training protocols caused a significant reduction in BMI and BFP of obese women. In contrast, VO2max significantly increased after both exercise training protocols. However, neither endurance nor resistance training protocols had a significant impact on the serum concentrations of irisin and total alkaline phosphatase activity. No significant inter-group differences were observed between the subjects’ BMI, BFP, VO2max, total alkaline phosphatase, and irisin at the end of protocols. Conclusions. The finding of the current study revealed that neither of the training protocols had a significant impact on bone anabolic parameters. However, performing these types of exercise is suggested for weight management in obese women.

Introduction: Inactive lifestyle is associated with decreased cardiorespiratory function and increased chronic non-communicable diseases and death. The aim of this study was to investigate the effect of six weeks of concurrent training (endurance-resistance) on the performance of the cardio-respiratory system in inactive young women. Method: In this quasi-experimental study, 16 inactive women of Tehran city were selected in a targeted and available manner and were randomly placed in two control groups (n = 8) and concurrent exercise (endurance and resistance) (n = 8). After the pre-test (anthropometric tests and gas analyzer), the concurrent exercise group (endurance and resistance) performed the concurrent exercise program for six weeks and three sessions every week, and the subjects of the control group did not have any special exercise. After the six-week training period, measuring anthropometric indices (body mass index (BMI), body fat percentage (PBF), muscle mass (SMM) and hip-to-waist ratio (WHR) and cardiorespiratory indices including (the first ventilatory threshold (VE/VO2), Second ventilatory threshold (VE/VCO2), maximum oxygen consumption (VO2max), respiratory exchange ratio (RER), heart rate (HR), forced vital capacity (FVC), forced expiratory volume in one second (FEV1), expiratory volume forced in one second to forced capacity (FEV1/FVC) and the ratio of oxygen consumption to heart rate (VO2/HR) was done using in-body device and gas analyzer. The data were analyzed by covariance analysis test at the P<0.05. Results: The results showed that six weeks of concurrent training (endurance-resistance) had no significant effect on the values of VO2max, FEV1, FVC, VE/VO2, VE/VCO2, FEV1/FVC, VO2/HR,HR in inactive young women (P<0.05). Also, after the training period, there was no difference in BMI, PBF, SMM and WHR indices between the training and control groups (P<0.05). Conclusion: According to the results of the research, it seems that six weeks of concurrent training (endurance-resistance) does not affect the performance of the cardio-respiratory system in inactive young women.
