Background and Aim: Delayed-onset muscle soreness after eccentric resistance exercise, which is usually part of military training, maybe due to damage to muscle structure. Nutrition can play a critical role in muscle damage by playing a vital role in both protein synthesis and catabolism. The aim of this study was to determine the effect of four weeks of separate and concomitant leucine and taurine supplementation on delayed muscle soreness indices and muscle pain perception rate after eccentric resistance exercise in young non-trained men. Methods: In this quasi-experimental study, 48 non-trained young men were randomly divided into four groups of taurine + leucine supplement (2 g of taurine and 0.1 g of leucine per kg of body weight per day), taurine supplement (2 g taurine per day), leucine supplement (0.1 g leucine per kg body weight per day) and placebo (1500 mg maltodextrin per day) and took supplement and placebo for four weeks. Delayed onset muscle soreness in lower body muscles developed using knee flexion with a weight equivalent to 70% of 1RM (3 sets and 15 repetitions). Serum creatinine kinase and lactate dehydrogenase enzymes were measured by photometry and muscle pain perception rate was measured using the Pain Assessment scale (PAS) at the time before, immediately after, 24, 48 and 72 hours after eccentric resistance training. Results: Comparison of changes in creatinine kinase activity and muscle pain perception rate showed a significant difference in different stages before and after eccentric resistance exercise (P<0.05). These changes were significant in the leucine + taurine group in the pre-test times up to 24 hours and 48 hours post-test compared to the leucine, taurine and placebo groups (P <0.05). Changes in lactate dehydrogenase activity between groups were not significant at different times. Conclusion: Concomitant use of leucine and taurine supplements can reduce some of the indicators of muscle damage and muscle pain perception rate after eccentric resistance exercise.

Background and Aim: In the health care system of any country, nurses play a pivotal role in improving and advancing matters related to community health. Therefore, it becomes very important to pay attention to this group’s job motivation. The aim of this study was to qualitatively analyze the factors that facilitate and inhibit job motivation in nurses working in the armed forces. Methods: The present study was qualitative and phenomenological. Eighteen participants were purposefully selected from nurses working in one of the hospitals affiliated by the Armed Forces in Tehran in 2020 until they reached data saturation. Data collection was carried out using semi-structured interviews and for analyzing the data, ATLAS-ti software thematic analysis was used. Next, the main and sub-topics were identified. Results: In this study, 2 main categories including “intrapersonal contexts” and “Job-organizational contexts” were identified as facilitators, 2 main categories including “individual problems and challenges”, and “external barriers and deficiencies” were identified as barriers. 27 sub-themes were also obtained. Conclusion: Considering that individual and external factors play a role in facilitating the external motivation of nurses working in hospitals, it is necessary for managers and officials to consider these factors in planning and decision-making and take the necessary measures.

Background and Aim: Fatigue and abnormalities in the lower extremities, such as the pronated foot, can adversely affect the biomechanics of human movements such as running, leading to a lack of muscle contraction and unstable symptoms in the joints of the lower extremities (knees). Therefore, the main purpose of this study was to investigate the effect of exhaustive protocol on knee muscle co-contraction in pronated and healthy individuals while running. Methods: Fourteen young men with pronated feet and 14 healthy feet participated in the study. Electromyography activities of the selected muscles before and after fatigue protocol were recorded. The statistical analysis was performed using the SPSS software and repeated measures analysis of variance (ANOVA) (P ≤0.05). Results: Findings in the pronated foot compared with the healthy foot group showed that the knee general cocontraction during the mid-stance phase (P = 0.026, d = 0.81) and swing (P = 0.046, d = 0.81) and Vastuslateralis/vastusmedialis directed co-contraction of the knee was significantly lower during the heel contact phase (P = 0.049, d = 0.81). Flexural/extensor directed co-contraction in comparison of pretest to posttest during heel propulsion phase in both groups of pronated foot (P = 0.037, d = 0.81) and healthy foot (P = 0.037, 0.81 = d) decreased significantly. The other components did not show any significant differences. Conclusion: The co-contraction of the examined muscles in the knee joint has decreased in pronated foot in different stages of stance compared to the healthy foot group. This may be due to the over-activity of a group of muscles to overcome the instability of the knee and to prevent the extra movements of this joint when fatigue occurs, and it is also possible that this over-activity of a group of muscles has affected the running mechanics of individual with pronated foot and at different stages of the running cycle caused additional pressure on the knee joint and the musculoskeletal system in the knee joint loses its ability to properly absorb shock when running, increasing joint looseness and the risk of joint damage due to fatigue Increase.
背景和目的:疲劳和下肢异常,如内翻足,会对人体运动(如跑步)的生物力学产生不利影响,导致肌肉缺乏收缩,下肢(膝盖)关节出现不稳定症状。因此,本研究的主要目的是研究穷举方案对内旋和健康个体跑步时膝关节肌肉共同收缩的影响。方法:14名年轻男性的内旋足和14名健康男性的脚参与研究。记录疲劳方案前后选定肌肉的肌电图活动。结果:与健康足组相比,内旋足组在站立中期(P=0.026,d=0.81)和摆动期(P=0.046,d=0.82)的膝关节总体共收缩和股外侧肌/股内侧肌定向的膝关节共收缩在足跟接触阶段显著降低(P=0.049,d=0.81)。在足跟推进阶段,与测试前和测试后相比,内旋足组(P=0.037,d=0.81)和健康足组(P=0.037,0.81=d)的弯曲/伸肌定向共收缩显著降低。其他成分没有显示出任何显著差异。结论:与健康足组相比,内旋足在不同站立阶段的膝关节肌肉共同收缩减少。这可能是由于一组肌肉的过度活动,以克服膝盖的不稳定性,一组肌肉的这种过度活动也可能影响了内旋足患者的跑步机制,并且在跑步周期的不同阶段对膝关节造成了额外的压力,增加关节松动和疲劳导致关节损伤的风险增加。

The data collection tools included a self-report questionnaire consisting of three as demographic characteristics, a 36-item (SF-36) and a GHQ-28 general health questionnaire. Finally, the data were entered into SPSS software version 16 and it examined with descriptive statistics (frequency, mean and standard deviation) and also analytical statistics such as independent t-test, one-way ANOVA and Tukey test for multiple comparisons. Results: The results showed that Staffs quality of life scores were moderate. Also, the average of general health score had a normal condition without symptoms. On the quality of life subscales, pain and physical function had the highest and lowest mean, respectively. The lowest average score in subscale’s depression in general health. There was a statistically significant relation between the quality of life score and all demographic variables except military-grade (P<0.05).
