Purpose: This study was designed to find the correlations between physical activity and insulin resistance of the middle-aged adults.
Methods: One hundred thirty one subjects participated in this study were age 40-60 from Y University"s center for physical exercise in W city. The data were collected from August 5 to October 5, 2009. To measure physical activity, the contracted Korean version of the Self-Report of Physical Activity Questionnaires of IPAQ was used. Insulin resistance was measured using fasting glucose levels, serum insulin levels, and HOMA method (serum insulin x fasting glucose/22.5).
Results: The continuous physical activity overall in this study was on average 1,792.30 ± 2,216.81 MET (min/week), and as a result of categorical classification: no activity was 66 subjects (50.4%); minimum activity, 41 (31.3%); and health-improving activity, 24 (18.3%), respectively. The overall degree of insulin resistance in these subjects was 2.20 ± 2.62 (0.28-12.74). There was negative correlation between moderate intensity activity and insulin resistance (r=-.189, p < .05).
Conclusion: These results revealed that promoting moderate-intensity physical activity is important in preventing and improving insulin resistance and possibly other metabolic risk factors in the middle-aged adults.
