Abstract

Introduction: the rating of perceived exertion (RPE) scale is an index for evaluating personal strain during dynamic activities. This study was carried out to determine the relationship between RPE and heart rate in the people with normal weight and overweight individuals during light and moderate physical activity levels under warm and hot experimental conditions.

Methods: This interventional study was conducted on 70 male students and employees (35 individuals with normal weight (BMI<25) and 35 with overweight and obesity (BMI≥25)). Each participant rested for 30 minutes and then performed a 60 minute light activity (2.8 kph on treadmill) with exposure to hot climatic conditions (370C). In the other phase, the participant was asked to rest for 30 minutes and then performed a 60 minute moderate activity (4.8 kph on tread mill) with exposure to warm climatic conditions (320C). The heart rate (by sport tester) and RPE 1-10 scale were recorded every 4 minutes. Finally, SPSS (ver. 16) was used using t-student test and Pearson correlation.

Result: There was a significant difference in the mean values of heart rate and RPE between two groups with normal weight and overweight in two climatic conditions (P<0.001). Also The Pearson's correlation coefficient showed that there was a positive relationship between RPE and heart rate in warm (r=0.75, p<0.001) and hot conditions (r=0.52, p<0.001).

Conclusion: The mean values of heart rate and RPE were higher in overweight and obese participants than those with normal weight. Also there was a significant correlation between heart rate and RPE but correlation coefficient was lower than other studies in warm and hot condition.

Abstract
Introduction: The fire fighting is one of the demanding and hazardous of all occupations so that it is recorded 96% deaths occurred in firefighters who were over 40 years old. Reported high activity of the sympathetic system and heart rates in excess of 95% HR during simulated or live firefighting tasks. The purpose of this study was determining the effect of ageing and overweight on biological motion indexes and cardiovascular risk factors in three group's age firefighters of Mashhad.
Methods: In this study, 195 firefighters from 26 fire stations selected by simple stratified sampling and placed in three groups aged I: 25-34, II: 35-44 and III: 45-54 years. Measuring dimension physical, aerobic power, anaerobic, explosive power, muscular endurance, agility and grip strength as an indicator of biological movement indexes (BMI) and TG; TC; LDL-c; HDL-c; atherogenic index of blood samples was measured as predictive of cardiovascular risk factors. In order to compare variables in three age groups, one-way variance analysis and Bonferroni correction test were used.
Results: Three groups showed a significant difference in biological movement indexes and cardiovascular risk factors (P<0.05). On the other hand, the biological movement indexes and cardiovascular risk factors in age groups 25-34 years have had better conditions than the other two groups.
Conclusion: Finding of this study showed that firefighters of Mashhad with increase of their age are overweight and obese and also their physical health may reduce.
