Abstract

Background: Security guard often experience sleep disturbances, especially insomnia due to the changing of sleep pattern. This sleep disturbance causes a decrease sleep quality on security guard. Exercise can prevent the decrease of sleep quality. This research aimed to determine the correlation between exercise and sleep quality of banks security guard in Surakarta. Methods: This was an observational analytic research with crosssectional design, which was held on November 2014 with security guard at Surakarta as the research subjects. Sampling method used simple random sampling. The dependent variable was sleep quality which was measured by questionnaire. The independent variable was exercise. The variable was measured by time accumulation of exercise in a week. It was categorized into exercise (?150 minutes/week) and non exercise (<150 minutes/week). Thirty eight research subjects was analyzed using Spearman correlation test. Result: The Spearman correlation test analysis showed a statistically significant strong correlation between exercise and sleep quality. Exercise had contribution 44.9% to improved sleep quality (R= 0.67; R2= 0.44; p=0.000). Conclusion: Exercise has strong positive correlation with sleep quality of bank security guard. Security officers who do exercise have better sleep quality. Key Words: Security guard, Sleep quality, Exercise.

Abstract

Background: The value of regular aerobic exercise in increasing HDL level of plasma has accepted widespread acceptance. In contrast, the only few studies have examined the effect of HDL-C level to exercise training. The objective of this study was to determine the most effective intensity of the aerobic exercise in increasing HDL plasma level. Method: This was an experimental laboratory study with randomized pre-test and post-test control group design. This study was conducted from April to June 2012 at Laboratory of Physiology FK UNS. Forty subjects were divided into four groups based on purposive sampling method. There were control group, mild-intensity group, moderate-intensity group and high-intensity group. The HDL level tests were taken before and after eight weeks of intervention. The results then were analyzed with one-way ANOVA test. Results: Based on one-way ANOVA test, there was significant difference among groups in the study (p = 0.002). Based on multiple comparison analyzes, (1) there was no significant difference between the raise of HDL plasma level in control group and mild-intensity group (p = 0.749), (2) there was significant difference between the raise of HDL plasma level in control group and moderate-intensity group (p = 0.044), and (3) there was significant difference between the raise of HDL plasma level in control group and high-intensity group (p = 0.002). Conclusions: High-intensity aerobic exercise was the most effective in increasing the HDL plasma level. Keywords: HDL, aerobic exercise, intensity
