This study was conducted to verify the changes in pain levels after experiments by using overweight adults with a fear of potential lower back pain as subjects.
The subjects were categorized by age, gender, and professional type. The changes in body-fat ratio and pain levels were recorded before and after the 12-week exercise program. The data collected were analyzed using SPSS 21.0 for statistical analysis and repeated measurement and variance analysis Findings.
The result was that first, there was a statistically significant difference in body-fat ratio before and after. The body-fat ratio was higher in males than in females and lower 12 weeks after the treatment than before. There was a statistically significant difference in the pain levels before and after, too. The pain levels were lower 12 weeks after the treatment than before. Second, there was a statistically significant difference in the body-fat ratio and pain levels across different age groups, with after-treatment levels being lower than before treatment. Third, there was a statistically significant difference in body-fat ratio and pain levels across different professional categories, with after-treatment levels being lower than before-treatment levels.
McKenzie/William exercises are considered to have contributed to increased muscular strength in the lower back. In this study, individualized exercises seem to have increased the stability in the lower back, and the resistance exercises increased stability, leading to reduced pain.
