Popis: INTRODUCTION Musculoskeletal disorders are considered among the most common and costly work-related problems in all countries [1]. ... [2, 3]. About 60 to 90 percent of older people have had back pain problems for some time, and about 15 to 20 percent of compensations received by people are due to these problems [4]. Azizpour et al. reported the highest prevalence of back pain, 54.2%, in Iran at the age of 15-50 years [5]. The existence of musculoskeletal disorders can affect the level of physical fitness of physical security personnel [6]. Also, proper physical fitness is the most basic need of the security forces and is one of the essential factors determining these people's performance. The low level of physical fitness of workers in this profession can have security consequences [7]. On the other hand, physical security workers complain of the spinal, knee, and back pain, mainly caused by a lack of proper health status and musculoskeletal disorders [8]. Also, during the studies conducted in this field, no specific solutions have been provided to resolve musculoskeletal disorders and improve physical fitness indicators [9, 10]. The first step to improve a physical security group's physical fitness and health is to evaluate the existing situation to reduce the cases of musculoskeletal disorders and also to know about their physical fitness indicators. AIM(S) The present study was conducted to examine the musculoskeletal condition and physical fitness related to health of the physical security personnel in one of the medical centers. RESEARCH TYPE The present study is descriptive-survey type. RESEARCH SOCIETY, PLACE & TIME All male physical security personnel at the Shahid Madani University of Azarbaijan, Iran, in December 2021 constituted the statistical population of this study. SAMPLING METHOD AND NUMBER The samples were selected by census sampling with 30 people. USED DEVICES & MATERIALS A checklist was used to collect data. First, the samples' age, heights, and weights were recorded. Height was measured with an accuracy of 0.1 cm and weight with an accuracy of 0.1 kg. Anthropometric measurement was evaluated using the body composition analysis device (Body Composition) 220 body model made in South Korea (Figure 1). This device measures total body fat percentage and body mass index (BMI), and waist-to-hip ratio (WHR) as based on body mass index, less than 20 is thin, 20 to 25 standard, 25 to 30 overweight, and more than 30 are considered obese [11]. Also, based on the waist to hip circumference, if this index in men is higher than 0.9, it is a risk factor for health [11]. The setting and reaching test was used to evaluate flexibility [12]. Muscular strength was measured using the Sargent jump [13]. Cardiorespiratory fitness (maximum oxygen consumption) was measured using the modified Bruce test on the Cosmos treadmill made in Germany (Figure 2). This protocol is designed in 9 stages, and each stage consists of 3 minutes, in which the slope and speed in the first stage start from 0% and 2.7 km per hour, respectively, and in the 9th stage, it reaches 22% and 9.6 km per hour. The details are written in Table 1. The following formula obtained Vo2max values [14]— maximum oxygen consumption=test time × 2.282 +8.545. The New York test was used to evaluate musculoskeletal conditions. This test was reported by Johnson and Nelson (1986) with validity and reliability coefficients of 0.93 and 0.98 [15]. METHOD After the approval of the project in Shahid Madani University of Azerbaijan with the research code 35646/D/227, all research objectives were explained for the samples and all the measurements for each person were done in one day in the Sports Physiology Laboratory of Shahid Madani University of Azerbaijan by a trained expert of this laboratory. There was no cost for the studied samples and all the devices and laboratory equipment used belonged to the administration and sports science department of Shahid Madani University of Azerbaijan. ETHICAL PERMISSION Written consent was received from all the subjects and the results of the tests were given to the individual in the form of an individual report. STATISTICAL ANALYSIS The Kolmogorov-Smirnov test was used to check the normality of the data. Also, one-sample t-test was used to compare the average of the studied indicators as well as the average with normal values. All studies were analyzed using SPSS 20 software at a significance level of p
