Background: Chronic low back pain (CLBP) is one of the most common musculoskeletal disorders. Physical activity (PA) is often recommended as part of the management of CLBP, but to date, no one particular exercise has been shown to be superior. Vibrating exercise equipment (VEE) is widely available and used despite little scientific evidence to support its effectiveness in the prevention and treatment of musculoskeletal problems. The aim of this study was to evaluate the efficiency of using VEE compared with sham-VEE in women with CLBP. Methods: A randomized (1:1 randomization scheme) single-blinded sham-controlled intervention study was conducted. Through simple randomization, 92 women aged 49–80 years were assigned to one of two groups: VEE (the experimental group) and sham-VEE (the control group). The VEE and sham-VEE intervention consisted of aerobic exercises with specific handheld equipment. Both groups performed physical activity twice weekly for 10 weeks. The erector spinae muscles’ bioelectrical activity (using an eight-channel electromyograph MyoSystem 1400L), lumbar range of motion (Schober’s test) and pain intensity (visual analog scale) were measured in all participants at baseline and after 10 weeks. Results: There was a significant decrease in the bioelectrical activity of the erector spinae muscles during flexion movement (left: Me = 18.2 before; Me = 14.1 after; p = 0.045; right: Me = 15.4 before; Me = 12.6 after; p = 0.010), rest at maximum flexion (left: Me = 18.1 before; Me = 12.5 after; p = 0.038), extension movement (right: Me = 21.8 before; Me = 20.2 after; p = 0.031) and rest in a prone position (right: Me = 3.5 before; Me = 3.2 after; 0.049); an increase in lumbar range of motion (Me = 17.0 before; Me = 18.0 after; p = 0.0017) and a decrease in pain intensity (Me = 4.0 before; Me = 1.0 after; p = 0.001) following a program of PA in the VEE group. Conclusions: No significant changes were found in intergroup comparisons. The beneficial changes regarding decreased subjective pain sensation in the VEE and sham-VEE groups may be due to participation in systematic physical activity. However, PA with vibrating exercise equipment could be a prospective strategy for increasing lumbar range of motion and for decreasing pain and erector spinae muscle activity in people with CLBP.

Background: The average lifespan is increasing worldwide, although the healthspan and quality of life is not. Many older adults either have a chronic disease, excessive body mass, or do not follow the healthy lifestyle recommendations as for nutrition and physical activity. Aim of the study: This study aimed to assess the relationship between body composition among senior women and health behaviors in the five domains of nutrition, body care, rest, safety and physical activity. Material and methods: The study group consisted of 36 women attending fitness classes. The Positive Health Behavior Questionnaire was used as the qualitative measurement and participant height, weight and body composition were measured. Body Mass Index (BMI), Waist-to-Hip Ratio (WHR ), Basal Metabolic Rate (BMR) were calculated. Results: Significant correlations (p≤0.05) were found between attending organized physical activities and higher muscle mass and higher BMR. Moreover, (a) sleeping at least six to seven hours at night correlated with a lower BMI and lower body fat mass; (b) spending at least 20–30 minutes a day resting correlated with lower visceral fat; (c) devoting at least 30 minutes daily to moderate or heavy physical exertion correlated with lower body fat mass, percent of body fat and visceral adiposity. Conclusions: The study shows strong relationships between physical activity, dietary patterns, rest, length of sleep, BMI, adiposity and muscle mass of physically active senior women. The results suggest it is necessary to actively promote and support older women in implementing healthy behaviors consistently in their life.
