The purpose of this study was to investigate the effects of lumbar combined exercise on serum lipid levels and inflammatory factors by applying the exercise to the elderly with chronic back pain.
The subjects include a total of 21 senior citizens (the exercise group: 10, the control group: 11) whose average age was 73.76 (±6.84) years old at the senior citizens' center at G Welfare Center in Seoul. The exercise group received lumbar combined exercise three times a week over a total of 12 weeks by using the HubEX System (Daeyang Mechanics, Seoul, KOR), which measures isometric and isotonic muscular strength. The exercise increased by 3~5% per week by the strength of 1RM 15~50% with each set containing 100 repetitions or fewer. A fasting blood test was administered to examine changes to body composition, serum lipid levels, blood glucose, and inflammatory factors before and after lumbar combined exercise. For data processing, a normality test was performed for prior values with one Kolmogorov Smirnov sample. Once normality was secured across all the variables of measurement, the investigator conducted a parametric test called repeated measures two-way ANOVA. The statistical significance level was set at .05 for all tests.
After the lumbar combined exercise, there were significant differences in HDL in serum lipid levels between the periods (p<.05). Significant differences were also found in the inflammatory factor IL-6 between the periods (p<.01), but it is difficult to conclude that it was the effect of the exercise since the control group as well as the exercise group showed a decreasing tendency.
In short, lumbar combined exercise will have a difficult time making a significant improvement with the serum lipid level and the Vascular Inflammation Indexes. Future study needs to apply various types of exercise (time, frequency and intensity) and examine in details their effects on pain relief, serum lipid, Vascular Inflammation Indexes, and physical strength including muscular strength.
