An Assessment of Cardio-metabolic Responses to a Bout of Progressive Exercise in Male Managers of Selected Universities in Iran

The aim of this study was to assess cardio-metabolic response to a bout of progressive exercise in the male managers of selected universities in Iran. In this study¡ 63 managers (age range 30-60 years) with at least 6 months of management were classified into 3 age groups: 30-40¡ 41-50 and 51-60. Modified Bruce protocol was used to perform progressive exercise on a treadmill. Blood samples were collected following a 10-hour fasting in two stages: before and after the protocol. Data were analyzed using dependent t-test¡ one-way ANOVA and Tukey post hoc test at significance level of 0.05. The results showed that a bout of progressive exercise significantly changed HDL-C (P values respectively 0.009¡ 0.001 and 0.001) and total cholesterol (P values respectively 0.001¡ 0.001 and 0.001) in all three groups. Changes in the LDL-C levels in the age group 41-50 (P=0.001) and adiponectin at the age of 40-30 (P=0.031) and 50-41(P=0.021) were significant. The inter-group changes were statistically significant only in cholesterol levels in 40-30 group compared with 51-60 group (P=0.038). The present study showed that a bout of progressive exercise on a treadmill had a significant effect on adiponectin levels and improved lipid profiles in male managers with different age groups in selected universities in Iran. Therefore¡ changes in lifestyle of these managers prevent cardiovascular diseases and increase their efficiency in working environments.
