Abstract
Background: The purpose of present study was to evaluate the effects of six- week aerobic step training on cardiovascular fitness, body composition, flexibility, leg anaerobic power and quality of life of isfahan university female students in academic year 2012-2011. Methods: 31 female students of Isfahan university were randomly assigned in experimental group (N=16, mean Age 27±2 , Weight 58.34 ±6.27, Height 1.61±4) and control group (N=15, mean Age25 ±1 , Weight 54.7±7.32, Height 1.61±6).pre test and post test measurements included cardiovascular fitness, body composition, flexibility, leg anaerobic power and quality of life questionnaire(WHOQOL(. analysis of covariance( ANCOVA) was used to test to effects of aerobic training as intervention(P<0.05). Results: There was a significant increase in cardiovascular fitness (p=0.001) and there was a significant decrease in body composition (p=0.046). There was no significant increase in flexibility (p=0.109) and leg anaerobic power (p=0.180). there was a significant increase in total score of quality of life(p=0.00). Conclusion: a six- week aerobic step training improves quality of life and cardiovascular fitness and body composition of training group

Abstract

Background and Objectives: One of the most important aspects of ergonomics is physiologic balance between human characteristics and their jobs. This study aimed to investigate the physiological characteristics of janitor, safety guard and facility workers of a work organization and determine their physiological fit.
Methods: A total of 70 staff were evaluated using Queen's college step test, N20 body composition analyzer, SECA scale, RS800CX Polar pacemaker. Descriptive statistics and analytical tests including ANOVA and Pearson correlation were used. The data was analyzed using SPSS 20.
Results: Body Mass Index (BMI) and fat percentage (Fat%) of employees were beyond the optimal range, but Waist to Hip Ratio (WHR) were in the range. Also, the average Maximum Volume of Oxygen consumption (VO2max) were 42/1±62/33 mL/kg/min and the average of working capacity (maximum Physical Work Capacity: PWCmax) were 16/63±4/46 kcal/min.
Conclusion: The results indicated that the level of some physical characteristics is inappropriate, physical fitness is poor and individual capabilities and job requirements are not in balance. Using standardized recruitment tests, providing the possibility of sports activities (by organizations) and finding integrated indicators that simultaneously take into account the physical, mental, social and environmental capabilities of individuals to determine work capacity (by researchers), can be facilitating steps to establish an ergonomic balance in the workplace.


Comparison of Indicators of Physical and Health-related Fitness and Body Composition in Different Age Groups of Workers

Volume 11, Issue 1 (5-2023)
Abstract
Objectives: The study of physical and health-related fitness and body composition indicators in workers is very important to prevent performance degradation. Therefore, this study aims to investigate such indicators among the employees of Izogam Shargh Company.
Methods: In this descriptive-analytical study, 150 workers from 150 stations in Mashhad city were selected by stratified random sampling and divided into three age groupsnamely. 25-34, 35-44 and 45-54 years. Two -way analysis of covariance (ANCOVA) and Bonferroni post-hoc test were performed to compare the variables in the three age groups.
Results: Significant differences were found in body composition indicators, i.e., weight between the age groups 25-34 years with 35- 44 years (P=0.008) and 35-44 years with 45- 54 years (P=0.001), body mass index between the age groups 25-34 years with 45-54 years (P=0.001) and 35-44 years with 45-54 years (P=0.001), body fat percentage between the age groups 25-34 years with 45- 54 years (P = 0.006), maximum oxygen consumption between the age groups 25-34 years with 35-44 years (P=0.001), 25-34 years with 45-54 years (P=0.001), and 35-44 years with 45-54 years (P=0.001). In addition, significant differences were found in all physical and health-related fitness indicators, i.e., agility, explosive strength, flexibility, abdominal muscle endurance, and shoulder girdle muscle endurance, between the age groups 25-34 years with 35-44 years (P=0.001), 25-34 years with 45-54 years (P=0.001), and 35-44 years with 45-54 years (P=0.001).
Conclusion: The results of this study show that the level of  physical fitness of employees decreases with age. Therefore, it is suggested that the managers of companies create the necessary conditions and incentives for employees to engage in regular physical activity.
