Sažetak
Resistance training (RT) has been shown to increase muscular strength and concurrently improve functional ability in elderly people (EP). However, there is relatively little research available regarding the impact of RT on health related fitness components in EP. PURPOSE: The aim of this study was to examine the impact of a 12-week RT intervention on body composition, flexibility, and cardio-vascular, respiratory and metabolic systems in EP. METHODS: 120 subjects were randomly assigned into three experimental (E1: 65-74, E2: 75-84 and E3: over 85 years) and tree by age equal control groups. The following outcome measures were assessed prior to, and immediately following the intervention: muscle mass, body fat, sit and reach, side lying hip abduction ROM, blood pressure, maximum heart rate (HRmax), basal metabolic rate, total cholesterol, LDL-Cholesterol and HDL- cholesterol, forced vital capacity (FVC) and forced expiratory volume in the first second (FEV1). Participants trained tree times per week for 12 weeks, for a total of 36 sessions. Each session consisted of the following 8 exercises: squats, step-ups, calf raises, back extensions, single arm/leg back extensions, sit-ups, vertical leg lifts, biceps curls with a stick. Pre- and post-intervention data were compared using paired t-tests or Wilcoxon signed ranks test, with an alpha set at p < 0.05. RESULTS: Following the 12-week intervention a significant increase was found for flexibility (2.26-8.67%), HRmax (2.11- 2.47%), basal metabolic rate (1.1-1.51%), FVC (0.3-0.7%) and FEV1 (0.5-0.9%) for all experimental groups. LDL- Cholesterol decreased for all experimental groups (5.35-11.57%) and blood pressure only for E2 (3.38%) and E3 (4.62%). Body composition positively changed only for E3 (muscle mass for 1.43%, and body fat for -2.54%). CONCLUSIONS: The study indicates that participation in a 12-week RT program may lead to improvement in flexibility, enhanced functions of cardio-vascular and respiratory system as well as betterment in some of metabolic system functions. Our study shows that RT is a physical activity suitable and recommended for elderly individuals as it has potential to improve health related fitness, which could lead to a healthier, more functional and independent aging.
