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.

Abstract
This study investigates the impact of an anterior cruciate ligament (ACL) injury prevention program on the performance of elite female kabaddi players. Given the debilitating consequences of ACL injuries, the primary aim is to evaluate the effects of an eight-week prevention program on improving the performance of these athletes. This quasi-experimental research was conducted on 27 elite female kabaddi players (aged 18 to 24 years), who were divided into intervention and control groups. The intervention group underwent an eight-week injury prevention training program. The tests included T-test, 20-meter run, Y-balance test, flexibility, hopping, and movement screening. Data analysis was performed using Levene's test and ANCOVA. The results of the ANCOVA indicated that the intervention group scored significantly better than the control group in the Y-balance test for both the right (p=0.002) and left (p=0.001) legs, single-leg hopping (right leg: p=0.004 and left leg: p=0.001), crossover hopping for the right leg (p=0.023), and the sit-and-reach flexibility test (p=0.003). However, no significant differences were observed in the speed, agility, triple hopping, and functional movement screening (FMS) tests. Results: The findings suggest that the eight-week PEP program has a significant impact on dynamic balance for both the right and left legs, hopping (single-leg and crossover hopping for the right leg), and hamstring and lower back flexibility in elite female kabaddi players. However, it did not have a significant effect on left leg hopping, speed, agility, or FMS scores.
