The present study aimed to investigate the relationship between the selected factors of related skill and health physical fitness with the classic risk factors of cardiovascular disease of employees of the police command in North Khorasan.

Methods and Materials:

 This research was conducted by correlation method with applied nature. The statistical population included 50 employees of the North Khorasan Police Force who were chosen randomly. Cooper’s test was used to evaluate cardiovascular endurance, the sit-up test was used for muscular endurance, the Wells test was used for flexibility, and the 100-meter running test was used to measure speed. To evaluate the serum levels of Triglyceride (TG), High-Density Lipoprotein (HDL), Low- Density Lipoprotein (LDL), and Total Cholesterol (TC), blood was drawn from the subjects, 48 hours after the performing physical fitness test, in 12 hours fasting condition. Descriptive statistics (mean and standard deviation) methods were used for data collection. Moreover, Kolmogorov–Smirnov test was used to confirm the normality the data distribution and spearman correlation coefficient to determine the correlation between the research variables. Data analysis has been performed using SPSS software version 22.

The results of the research showed that there was inverse and significant relationship between cardiovascular endurance and TC (p= 0/024, r= -0/319); however, there was not any significant relationship between cardiovascular endurance and HDL, LDL and TG. Regarding the values of muscular endurance, the results of the test showed that the mentioned index has inverse and significant relationship with TC (p= 0/033, r= -0/302); however, there was not any significant relationship between muscular endurance and HDL, LDL and TG. There was not any significant relationship between flexibility and HDL, LDL, TC and TG. Finally, there was a direct and significant relationship between speed and TC and TG values (p= 0/018, r= 0/332), (p= 0/037, r= 0/296). However, there was not any significant relationship between speed and HDL and LDL.

Based on the findings of the present study, it can be concluded that people who have higher cardiovascular endurance and muscular endurance have a lower and more favorable TC level than people who have lower cardiovascular endurance and muscular endurance. Furthermore, the lower the speed record in people, the lower their TC and TG will be.

Musculoskeletal disorders are any abnormality of the skeletal-muscular system and nerves which reduces the optimal function of organs. Therefore, the purpose of this study was to compare musculoskeletal disorders in the upper limbs of male athletes with non-athlete males who are obese and non-athlete males who are thin.

This descriptive-analytical study was conducted on 15 male athletes, 15 obese males, and 15 non-athlete thin males in North Khorasan Province during the year 2021. The selected subjects were purposefully chosen from the available community. Kyphosis and lordosis angles were evaluated using a flexible ruler. Evaluation of forward head and forward shoulders was performed from the side view with digital cameras, and the angles were analyzed by AutoCAD software. For data analysis, ANOVA test and Shafa's follow-up test were used.

IAccording to the results, in all musculoskeletal abnormalities of the upper limb, except for lumbar lordosis, male athletes had a higher percentage of abnormalities than non-athlete obese males and non-athlete thin males (P<0.05). Lumbar hyperlordosis was higher in obese males compared to athletes and non-athlete thin males (P<0.05).

Based on the research findings, it can be concluded that abnormalities in the head, shoulders, and spine areas can be affected by the type of sport due to repeated movements and techniques, and obesity is also a factor in the development of musculoskeletal abnormalities.

Objective :

The purpose of study was the effect of 8 weeks training shallow water on static balance of military with knee injuries.

Methods:

 Subjects of this research there were the Number of person 46 military in north khorasan province, They participated in this study purposefully and voluntarily. Subjects were randomly divided into two experimental groups of 23 people (Mean±SD, age (y) 33.65±6.62, height (cm) 183±6.95, weight (kg) 76.75±2.80) and a control group of 23 people (Mean±SD, age (y) 34.45±6.97, height (cm) 181±7.41, weight (kg) 71.66±3.20). To measure static balance were used the stork test. Were used For analyze the results of descriptive statistics (Mean±SD) and were used Inferential statistics method (Shapiro–Wilk test, dependent t and independent t).

Results :

The test results showed there is a significant difference between pre-test and post-test in the experimental group (P=0.001). So that was not observed significant difference between pre-test and post-test in balance (P=0.393), Also, a significant difference was found between the experimental and control groups (P=‌0.001).

Conclusion:

 Based on research results, it can be concluded that shallow water training is significant on the static balance of soldiers with knee injuries and this can indicate the greater effectiveness of exercises in shallow water so practice in the water it can be recommended as a way to improve static balance in people with knee injuries.

The aim of this study was compare the effect of eight weeks high intensity interval training (HIT) and morning training on lipid profile of Police force personnel. Methods For this purpose, 50 employees of Bojnourd Police force, randomly divided into two groups: 1. HIT training and 2. Morning training. HIIT Training subjects do HIT training 3 times per week for 8 weeks with 90% of maximum heart rate. Lipids profile levels, 12 hours before the first session and 48 hours after the last session, were measured. For data analysis from paired t test and Wilcoxon for within group change and independent t test and U-mann whitney for between group change in significant level of P<0.05, were used. results show that 8 weeks of HIT training an significantly reduces LDL, TG and TC level (P<0.05). Eight weeks of morning training had no significant effect on any of the research indicators. Between 8 weeks of HIT training and morning training in LDL, TC, TG, levels in polis force personnel, significant difference was observed. this results show that HIT training have positive effect on lipids profile of police force personnel; so it can be reduce classical cardiovascular risk factor in polis force personnel, HIT training be added to morning training.

 This study aimed to investigate the static and dynamic balance in basketball students with an ankle injury history.

 Subjects of this study were 36 elementary school basketball male students who participated in this study purposefully and voluntarily. Subjects were divided into two groups of 18 people with an ankle injury and the control group without ankle injury. To measure the static balance from the stork test and the dynamic balance from the star test was used. Descriptive statistics (mean and standard deviation) and inferential statistics (Shapiro-Wilk test and independent t-test) were used to analyze the results.

 There was a significant difference between the static balance of basketball students and the control group (P=0.001), but no significant difference was found between basketball studentschr('39') dynamic balance with ankle injuries and the control group (P=0.0887).

 Based on research results, it can be concluded that lower limb injuries, especially ankle injuries they can influence postural control and static balance of basketball students and caused some functional disability. Also recommended coaches during the sports era of basketball players to design specific exercises to strengthen ankle muscles and ligaments and use static balance exercises not to witness this type of injury.

The aim of present study was to compare the effect of 8 weeks high intensity interval training (HIT) and morning exercises on physical fitness of north khorasan police force. For this purpose, 50 police force personnel of Bojnourd, were randomly divided into 2 groups: HIT training
(25 persons) and morning exercises (25 persons). HIT Training protocol was above 90 percent of maximum heart rate for 8 weeks and was conducted 3 sessions per week. Morning exercise group performed daily morning exercise for 8 weeks. Physical fitness test was performed before and after of 8 weeks of HIT and morning exercises. For data analysis paired T-test and Wilcoxon to within group and independent T-test and U-Mann whitney to between group were used in P<0.05. results showed that 8 weeks of HIT training have significant effect on cardiovascular fitness, muscular endurance and speed (P <0.05) but eight weeks of morning exercise had significant effect on cardiovascular fitness. In addition, between 8 weeks of HIT a morning exercises on cardiovascular fitness, muscular endurance and speed in police force, significant difference was observed. HIT training has positive effect on physical fitness factor in police force personnel and so suggested to increase the physical fitness in police force personnel, HIT training added to morning exercises.
