Background: The authors assessed the effect of bandwidth modeling in learning relative timing and absolute timing. Method: Participants were 10 male high school students who volunteered to participate in the experiment (M age = 16 years, SD = 0.942 years). None of the participants had prior experience with the task or was informed about the purpose of the experiment. They had to learn soccer chip shot under either a bandwidth (model delivered when participant’s performance was outside a predefined bandwidth or rang) or yoked (same number of model provided as bandwidth group) modeling procedure. Results: The results show that the bandwidth group was more effective in learning relative timing than the yoked group. Conclusions: It indicated that benefits of feedback frequency reduction is generalizable to observational learning context. The authors propose that this method may be an appropriate method for relative timing learning.

This experiment assessed the effectiveness of two interventions; mental imagery and physical training as compared to a control group, on their ability to improve visuomotor accuracy, measured by scores achieved on a visuomotor task. For mental imagery participants had to imagine throwing a dart and for physical training participants physically practised dart throwing. Measurements were recorded pre-intervention, after two weeks of training (Mid-intervention), after five weeks of training (Outcome Measure 1) and two weeks after training (Outcome Measure 2). Comparison of Mid-intervention, Outcome Measure 1 and Outcome Measure 2 with baseline showed both interventions to significantly increase performance on dart throwing compared to the Control group. Our findings show that, as well as traditional physical practise, mental imagery can effectively improve performance on a fine visuomotor task. This is an important finding highlighting possible applications of mental imagery in those with limited motor abilities to maintain or enhance motor movement.

Purpose: The aim of this study was to compare the effects of three methods of endurance, resistance and concurrent training on aerobic fitness and body composition male students with overweight. Methods: Forty five overweight male who were resident of Shahed university dormitory were purposefully selected and randomly assigned into following groups: endurance, resistance and concurrent training. Each Group performed their own protocol for 8 weeks, 3 times per week with specified intensity and duration. Before starting the protocol and 24 hours after the last training session, body composition parameters and aerobic fitness were measured at same condition. Data were analyzed using analysis of covariance. Results: The findings showed that three methods of endurance, resistance and concurrent training protocol had a significant effects on aerobic fitness and body composition parameters. In comparing the difference between groups of three methods of endurance, resistance and concurrent training on aerobic fitness and body composition parameters were significantly different and the variables of aerobic fitness and body composition parameters of concurrent training was more effective than two other exercises. Innovation this research is identical the work out of training (time) in the 3 protocol that to compare intergroup among the most effective way to same time identification. Conclusion: It seems that eight weeks of endurance, strength and concurrent exercise training have effects on aerobic fitness and body composition parameters male students with overweight but all three types of exercise separately with diet modification could be improved aerobic fitness and body composition indices.

Introduction: The present study aimed to examine a proposed model for the relationship between resilience and emotional reactions to failure, mediated by self-compassion and Emotion Regulation (ER) among martial artists. Materials and Methods: A total of 286 athletes (191 males & 95 females; Mean±SD age: 20.98±3.30 years) from different disciplines of martial arts (taekwondo, karate, Judo, & wushu) engaged in league championship participated in the study. Athletes completed the Sports Mental Toughness Questionnaire (SMTQ), the Positive and Negative Affect Schedule (PANAS), the Self-Compassion Scale (SCS), and the Cognitive Emotion Regulation Questionnaire (CERQ). The proposed model was evaluated using structural equation modeling. Results: The obtained results revealed that resilience has direct and indirect effects on emotional reactions to failure. Furthermore, self-compassion and maladaptive ER play a partial negative mediating role between resilience and emotional reactions to failure. However, the mediating role of adaptive ER was not significant. Conclusion: The study data predicted negative emotional reactions to failure based on resilience, mediated by self-compassion and ER among martial artists; thus, these data indicate the necessity of paying attention to the development of resilience in martial artists. This method emphasizes self-compassion and the reduction of maladaptive ER for better recovery of failure and reduces its effects.
