Background & Aim: This study aimed to investigate the effect of cardio kickboxing workouts on cardiorespiratory endurance, body composition, quality of life, and sleep quality of young male students living in dormitories. Methods: The research method was a quasi-experimental pretest-posttest design with a control group. To carry out this research, 20 male students in the Allameh Tabatabaei University dormitory were randomly selected and divided into two experimental and control groups, each group consisting of 10 people. In order to determine cardiorespiratory endurance, body composition, quality of life, and sleep quality, Queen''''''''s College Step Test (QCT), body fat percent using calipers, 36-Item Short-Form Health Survey questionnaire (SF-36), and Pittsburgh Sleep Quality Index (PSQI) were employed, respectively. Results: Based on the analysis of covariance of the data related to pretest and posttest of the two experimental and control groups, the data of four variables of fat percentage, cardiorespiratory endurance, quality of life, and sleep quality in the posttest were significantly different between the two groups that this statistical test was conducted at a significance level of P = 0.05. Conclusion: It appears that cardio kickboxing workouts have a positive impact on the health of male students in dormitories.

Introduction: To examine the effects of a 6-week hopping exercise program on time to stabilization and perceived stability among athletes with chronic ankle instability. This is a randomized controlled trial.Materials and Methods: A total of 28 basketball players with chronic ankle instability (Mean±SD age; 22.67±2.88 y, Mean±SD weight: 80.47±8.48 kg, Mean±SD height: 186.82±3.09 cm) participated in this study and were randomly divided into two equal groups of 14 people each: 1. Experimental; and 2. Control. The experimental group performed hop exercises 3 times per week for 6 weeks. The control group received no intervention. Time to stabilization for anterior-posterior and medial-lateral components of ground reaction force, as well as ankle joint function assessment tool were found before and immediately after the exercise program. Descriptive statistics, independent t-test, and paired sample t-test were used to analyze the data at the significance level of 95% (α≤0.05).Results: The 6-week hopping exercise program led to a significant decrease in the time to stabilization of medial-lateral and anterior-posterior of ground reaction force and also a significant increase in the score of ankle joint function assessment tool (p <0.05).Conclusion: Given the effectiveness of hopping exercises, postural control deficit, and time to stabilization in sport exercises, it is suggested that these selected exercises be used in training and rehabilitation protocols.
