One of the most common methods for assessing cardiac damage is the measurement of biological indicators related to heart tissue damage. This study aimed to compare the effects of two types of acute weight loss programs (2 and 4%) on the levels of creatine kinase and troponin enzymes in the elite wrestlers.

For this purpose, 16 young wrestlers (age: 18±1.31 years, weight: 71.68±13.17 kg, height: 171±6.40 cm) in the form of crossover were randomly divided into two groups with weight loss of 2 and 4% of body weight. Blood samples were analyzed in four stages: before, immediately, 6 hours and 24 hours after losing weight. Repeated measures ANOVA and Bonferroni post hoc test for evaluation of within groups variations, and independent T-test for comparison between groups were used.

The results of this study showed that CK-MB was significantly increased in two groups after weight loss (P=0.009). However, within 24 hours after weight loss, the level of isoenzyme creatine kinase returned to the level of resting. Also, there was a significant increase in cTnI level in the two groups (P=0.004), this difference was more in the 2% than the 4% group, however, within 24 hours; weight loss was returned to resting levels.

Although the level of CK-MB and cTnI enzymes increased in two groups after rapid weight loss, but rapid weight loss of 2 and 4% of body weight cannot cause serious cardiac damage.

Anatomical alignment of the lower extremity has been proposed as a risk factor for lower extremity injuries. Although, functional performance tests are dynamic tests are dynamic measures used to assess lower body function, there are limited researches on the functional performance deficits in patients with excessive pronated foot. Therefore, the aim of this study was to compare functional performance deficits in female athletes with excessive pronated foot. 20 subjects with excessive pronated foot participated in this study. Inclusion criteria consisted of no injury of lower extremities within three mounts prior to the study, no history of neuromusculoskeletal diseases, and no prior surgery. Each subject completed a demographic questionnaire, and then the measurement protocol began, with the participant’s neutral foot serving as the control. Figure 8 hop and side hop tests were used to assess the functional performance deficits in both limbs. The total time of protocol was recorded with a handheld stopwatch to the nearest 0.01 second. Navicular drop was then measured using a modified Brody technique. ANOVA test was used to compare functional performance deficits in excessive pronated and neutral feet of dominant vs. non-dominant legs (p≤0.05). The results of functional performance tests indicated that the mean of total time of functional performance was lower in the neutral foot than excessive pronated foot and a significant difference was observed in functional performance deficits between neutral and excessive pronated foot (p≤0.05). No significant difference was observed between dominant and non-dominant legs as well as in interaction between the neutral–excessive pronated feet and dominant – non-dominant legs (p≤0.05). These findings indicated the effect of excessive pronated foot on functional performance of foot.
