| ABSTRACT | |||
| We investigated the associations between cardiovascular function
and both body mass index and physical fitness in Korean men. The subjects
were 2,013 men, aged 20 to 83 years, who visited a health promotion center
for a comprehensive medical and fitness test during 2006-2009. The WHO's
Asia-Pacific Standard Report definition of BMI was used in this study. Fitness
assessment of cardiorespiratory endurance, muscular strength, muscular endurance,
flexibility, power, agility, and balance were evaluated by VO2max
(ml/kg/min), grip strength (kg), sit-ups (reps/min), sit and reach (cm),
vertical jump (cm), side steps (reps/30s), and standing on one leg with
eyes closed (sec), respectively. For cardiovascular function, we evaluated
systolic blood pressure (SBP), diastolic blood pressure (DBP), resting heart
rate (RHR), double product (DP), and vital capacity. There were significant
decreases in cardiorespiratory endurance (p < 0.001), power (p < 0.001),
and balance (p < 0.001), and increases in muscular strength (p < 0.001).
Further, cardiovascular function, including SBP (p < 0.001), DBP (p <
0.001), double product (p < 0.001), and vital capacity (p=0.006) appeared
to be lower for the obesity group. We conclude that an obese person exhibits
lower fitness level and weaker cardiovascular function than a normal person.
Key words: Body mass index, obesity, physical fitness, cardiovascular function. |
