Abstract
Introduction: Obese females have a lot of physical and psychological problems, and in this field, strength training with an elastic band can help. Therefore, the present study aimed to determine the effect of strength training with elastic band on Body Mass Index, quality of life, and psychological well-being in obese females.
Methods: This study was quasi-experimental with a pre and post-test design with experimental and control groups. The research population was obese females referring to nutritional clinics of Qarchak city in 2018, who, among them, 40 females were selected by the available sampling method and randomly divided into two equal groups. The experimental group received two months (three sessions a week) the strength training with the elastic band by exercise instructor and the control group placed on the waiting list for training. Data were collected by instruments of body mass index and quality of life and psychological well-being questionnaires and were analyzed in the SPSS-18 software with multivariate analysis of covariance method.
Results: The findings showed that there was a significant difference between the experimental and control groups in all three variables of body mass index, quality of life, and psychological well-being. In other words, the strength training with the elastic band led to a decrease in body mass index (F = 388.761) and increase the quality of life (F = 167.168) and psychological well-being (F = 175.576) in obese females (P < 0.05).
Conclusions: It is recommended that nutritionists and coaches of sports clubs use from strength training with the elastic band method along with other ways to improve the body mass index, quality of life, and psychological well-being of obese females.

Abstract
Introduction: High stress in nurses' workplace is one of the leading causes of burnout among them. For this reason, nurses need to be trained to overcome their burnout. The purpose of this study was to compare the effectiveness of using signature strengths in a new way and affective capital promotion training on burnout of nurses.
Methods: The research method was semi-experimental, and the research design was three groups with two stages of pre-test and post-test. Among nurses of a government hospital in Isfahan in the spring of 2019, based on criteria of entry and exit, 45 nurses were selected and then randomly assigned in two experimental groups and a control group (each group with 15 nurses). The burnout questionnaire (with three components of physical fatigue, cognitive weariness, and emotional exhaustion) was used in pre-test and post-test stages to measure the dependent variable. The using signature strengths in new way training and affective capital promotion training were conducted during ten sessions. Data were analyzed by multivariate analysis of covariance using SPSS software.
Results: The results revealed that the cognitive weariness (F = 9.08, P < 0.01), and emotional exhaustion (F = 6.55, P < 0.01) in the using signature strengths in new way training group and affective capital promotion training group were significantly lower than the control group, but there is no significant difference between two experimental groups and a control group in physical fatigue (P > 0.05).
Conclusions: The results confirmed the effectiveness of using signature strengths in a new way and affective capital promotion training on reducing cognitive weariness and emotional exhaustion of nurses. It is suggested that using signature strengths in a new way, and affective capital promotion training be used to more effectively manage nurses' cognitive weariness and emotional exhaustion in hospital settings.

Abstract
Introduction: Cerebral palsy is the most common sensory-motor disorder that causes movement restriction and reducing social participation in children. Therefore, the purpose of this study was to investigate the effect of eight-week combined strength-balance training on muscle strength, balance, and quality of life in children with monoplegic cerebral palsy.
Methods: The present study was quasi-experimental and was conducted as a pretest-posttest with a control group. Sixteen boys, with the average age (13.48 ± 1.41 years) and with monoplegia cerebral palsy, were voluntarily selected and randomly divided into equal experimental (N = 8) and control (N = 8) groups. Participants in the experimental group participated in a combined strength and balance training program (3 days per week, for eight weeks). In contrast, those in the control group did not participate in an exercise program. Muscle strength, static balance, and quality of life were assessed before and after the exercise protocol. Data were analyzed using pair t and independent t-tests at a significance level of 0.05.
Results: After the 8-week training, a strength of the superior and affected hand, static balance, and quality of life, participants in the experimental group had significant improvement over their baseline values (P < 0.001). The range of changes in all studied variables in the experimental group was significantly higher than the control group (P < 0.01).
Conclusions: Combining exercise training can improve muscle strength, balance, and quality of life in children with monoplegia cerebral palsy. However, a definite statement in this regard is required to further investigation.

Abstract
Introduction: Landing mechanics, lower limb muscle strength and central stability are risk factors for anterior cruciate ligament injuries in young football players. The aim of this study was to investigate the effect of the knee control injury prevention program on landing mechanics, strength of selected lower limb muscles and central stability in adolescent male soccer players.
Methods: The statistical population of this semi-experimental research included teenage soccer players with poor landing mechanics, 50 of whom were purposefully selected as a statistical sample and then randomly divided into two groups of experiment (number = 25 people, age = 62/ 12.70 ± 0 years, height = 1.52 ± 0.07 meters, weight = 48.87 ± 6.6 kg) and control (number = 25 people, age = 12.58 ± 0.65 years, height = 08 1.52 ± 0.0 m, weight = 50.45 ± 6.79 kg). In this study, landing mechanics were evaluated with the landing error test, thigh abduction and external rotation strength with MMT, and central stability with McGill tests at the beginning and end of the study. The subjects of the experimental group used the knee control program in the warm-up section for 8 weeks. While the control group did their usual warm-up during this time. Yeoman-Whitney and ANOVA tests were used to compare the differences between the two groups.
Result: The results showed that the experimental group compared to the control group after the test had a significant decrease in the landing error test scores (Z = -5.62; P = 0.001) and a significant improvement in thigh abduction strength ( F = 14.26; P = 0.001), thigh external rotation strength (F = 10.74; P = 0.002) and central stability tests (F = 26.39; P = 0.001).
Conclusion: This study showed that the implementation of the knee control injury prevention program can improve the landing mechanics, abduction and external rotation strength of the thigh, and central stability in teenage soccer players. Therefore, it seems that the knee control program can be effective in preventing the risk of anterior cruciate ligament injuries in young male football players.

Abstract
Introduction: It seems that investigating factors that reduce falls and also the effect of physical activities during activities are more effective in reducing falls in the elderly. Because the elderly fall during activity or walking, not in a stationary state where postural control is measured. Therefore, the aim of this study was to compare the effect of strength and balance training on the reactive postural control of healthy elderly people.
Methods: The current research is semi-experimental in terms of method and strategy; and in terms of the topic, it was applied research with a pre-test-post-test design. The current research includes two experimental groups (strength training group and balance training group) and one control group. The statistical sample of this research included 36 people (12 people in each group) with an age range of 60 to 75 years. Electromyographic muscle activity was used to evaluate the reactive postural control of the elderly. To analyze the data, two-way analysis of variance and Bonferroni post hoc tests were performed at a significance level of p≥0.05. Statistical software SPSS version 26 and Excel 2019 were used for statistical calculations and drawing graphs.
Results: The results of this study showed that balance training (P=0.001); and strength training (P=0.001). They have a significant effect on the reactive postural control of the elderly. Also, the results of the research showed that there is no significant difference between balance exercises with strength on the reactive postural control of the elderly (p<0.05).
Conclusion: It seems that both balance and strength training have a significant effect on the reactive postural control of the elderly. Also, the results showed that there is no significant difference between balances with strength training on the reactive postural control of the elderly. Therefore, both balance and strength training can be used as an alternative to improve the reactive postural control of the elderly and thus reduce the risk of falls in the elderly.
