Abstract

The most common side effect of physical activity is the risk of musculoskeletal damage, that anterior cruciate ligament injury is the most common one. Purpose of the study is comparing the effect of six weeks of comprehensive injury prevention training on anterior cruciate ligament with internal and external feedback on the proprioception and knee function of active female university students. Forty five active female university students aged 18-25 years were volunteered and randomly assigned to three groups (internal, external and control) and they performed the protocol three times a week for six weeks. Proprioception and function of the knee joint were measured using goniometer and functional tests in two stages  namely pre-test and post-test. Statistical analysis of covariance, paired t test and Tukey's post hoc tests were used for statistical analysis with a significant level of p≤0.05. Overall results of the study showed that the present exercise protocol with internal and external feedback had a significant effect on the proprioception of p≤0.001 and p=0.000 for the knee performance and there was no significant difference between the two training groups. Regarding the results of the study, it is suggested that the present training protocol be addressed by coaches and sport sciences specialists as a complementary tool and method, along with other training methods, for those who are prone to damage to the anterior cruciate ligament.

Abstract

The purpose of this study was to compare two methods of aerobic exercise on the levels of SOD and TNF-α in the heart tissue of diabetic rats. 40 male Wistar rats aged ten weeks were randomly divided into four groups of 10: healthy control, diabetes, diabetes+MIT and diabetes+HIT. The moderate intensity training group ran 5 sessions per week for 8 weeks on the treadmill for 60 minutes at a speed of 25 meters per minute, and the high intensity training group also 5 sessions per week for 8 weeks with a training time of 60 minutes and at a speed of 34 meters per minute. The heart tissue of rats was examined to determine the amount of changes in SOD and TNF-α using ELISA method. To investigate the difference between groups of variables, one-way analysis of variance and Tukey's post hoc statistical tests were used at the significance level of P≥0.05. The results showed that there was a significant difference in the levels of TNF-α and SOD in the heart tissue of rats among the four research groups (P≤0.001). The levels of TNF-α in the HIT training group also showed a significant decrease compared to the diabetic group (P=0.001), While these changes in the MIT exercise group compared to the diabetes group was a non-significant decrease (P=0.117), the amount of SOD levels between the MIT and HIT exercise groups also showed a significant increase compared to the diabetic group (P=0.001). It seems, aerobic exercise with different intensities can improve SOD and TNF-α levels. Although the intensity of exercise in periodic exercise has been an effective factor in changing the values of both variables.
