Abstract
Introduction: Studies have shown that anterior cruciate ligament injury causes long-term periods of disability and long-term effects; Therefore, it is necessary to adopt preventive measures as well as to have studies that determine the effect of injury prevention programs in improving the performance level of players. Therefore, the purpose of this study was to investigate the effect of eight weeks of the anterior cruciate ligament injury prevention program on the function of elite female kabaddi athletes.
Materials and Methods: This research is semi-experimental based on the application of the intervention variable. 27 female kabaddi athletes with an age range of 18-24 years were randomly divided into two intervention and control groups. The intervention group performed prevention injury and enhance performance program exercises for 8 weeks. The tests were taken before and after eight weeks of the PEP program. These evaluations included T-test, 20-meter sprint test, Y-balance test, sitting and reaching flexibility test, hopping test and functional movement screening test. leven's statistical test was used to check the homogeneity of variances and ANCOVA test was used to evaluate and compare the data.
Findings: The results of the covariance analysis test showed that the intervention group had significantly better scores compared to the control group in the Y-balance tests of the right (p=0.002) and left leg (p=0.001), single leg hopping with right leg (p=0.004) and left leg (p=0.000), crossover hopping with right leg (p=0.023) and sit and reach flexibility test (p=0.003) after eight weeks of exercises In addition, in the tests of sprinting (p=0.649), agility (p=0.073), triple hopping with left leg (p=0.784) and right leg (p=0.204), crossover hopping with left leg (p=0.540) and functional movement screening test (p=0.943) did not show any significant difference between the two groups.
Results: The results of this research showed that the eight-week prevention injury and enhance performance program has a significant effect on the dynamic balance of the right and left legs, hopping (single leg hopping and crossover hopping of the right leg), and the flexibility of the hamstrings and lower back of elite female kabaddi athletes; But hopping (triple hopping and left leg crossover hopping), speed, agility and FMS test scores have no significant effect.

Abstract
Nurses, especially nurses in the intensive care unit, experience significant job stress that can endanger their health and cause a decrease in their sleep quality and happiness, and as a result, the quality of care for patients, and considering that the working conditions of the nurses in the intensive care unit Especially, it is in a way that increases emotional pressure and sad mood. Therefore, this study was conducted with the aim of determining the effect of online Pilates exercise on the quality of sleep and happiness of nurses in the intensive care unit.
The study was a quasi-experimental type of pre-test-post-test with two intervention and control groups and was conducted on 70 female nurses with an average age of 30.14±3.26. The intervention was held online in 8 sessions (3 sessions per week, 50 minutes in the afternoon in the form of warm-up exercises, main exercises and cooling down). Data were collected using the Pittsburgh Sleep Quality and Oxford Happiness Questionnaires and analyzed with spss 23 software and chi-square, t-test, and Mann-Whitney tests. At the beginning of the study, there was no statistically significant difference between the two groups. But at the end of the intervention, the average score of total sleep quality (p=0.045) and happiness (p=0.0001) showed a significant improvement in the intervention group.To improve physical and mental health, improve the quality of life, sleep and happiness, classical Pilates exercise can be recommended to be included in daily programs.

Abstract
Lactate has been recently considered as a signaling factor involved in metabolism. The aim of this study was to investigate the role of lactate entrance into the brain on endurance training-induced adaptations in lipid oxidation.
24 male rats (age: 8 weeks, weight: 197 ± 21 g) were divided into control (C), trained (T), and traind+4-CIN (T+4-CIN, which experienced the inhibition of lactate entrance into the brain during exercise). All animals performed a single session of acute endurance exercise following their 12-weeks training protocol. Free fatty acids (FFA) and triglyceride content in plasma and adipose tissue and cAMP and Inositol triphosphate (PI3) content in epididymal fat were measured immediately after acute exercise using ELISA and were compared among the groups by one-way analysis of variance (ANOVA).
Acute exercise significantly increased lactate concentration in cerebrospinal fluid (SCF) in both T and T+4-CIN compared to the C group. Lactate concentration was slightly lower in T + 4-CIN compared to the T. Immediately after acute endurance training, a significant decrease of 61 and 31% in plasma triglyceride levels, a significant decrease of 39 and 26% in adipose tissue triglyceride levels, a significant increase of 125 and 56% in plasma FFA levels, a significant increase of 217 and 125% increase in FFA plasma levels, a significant increase of 87 and 41% in adipose tissue cAMP levels, and a significant increase of 90 and 49% in adipose tissue inositol triphosphate levels was observed in the T and T+4-CIN compared to the control group, respectively (all P < 0.01). Plasma triglyceride and adipose tissue levels in the 4-CIN + training group were significantly higher and plasma and adipose tissue FFA levels were significantly lower (all P < 0.05) than the values found in the T group. In conclusion, the results of the present study showed that lactate can be effective on endurance training-induced adaptations in lipid oxidation due to its action in the brain.
