Twelve Weeks of Whole Body Vibration Training Improve Regucalcin, Body Composition and Physical Fitness in Postmenopausal Women: A Pilot Study

Abstract

(1) Background: Regucalcin or senescence marker protein 30 (SMP30) is a Ca2+ binding protein discovered in 1978 with multiple functions reported in the literature. However, the impact of exercise training on SMP30 in humans has not been analyzed. Aging is associated with many detrimental physiological changes that affect body composition, functional capacity, and balance. The present study aims to investigate the effects of whole body vibration (WBV) in postmenopausal women. (2) Methods: A total of 13 women (aged 54.3 ± 3.4 years) participated in the study. SMP30, body composition (fat mass, lean mass, and bone mass) and physical fitness (balance, time up and go (TUG) and 6-min walk test (6MWT)) were measured before and after the 12 weeks of WBV training. (3) Results: The WBV training program elicited a significant increase in SPM30 measured in plasma (27.7%, p = 0.004) and also in 6MWT (12.5%, p < 0.001). The WBV training also significantly reduced SPM30 measured in platelets (38.7%, p = 0.014), TUG (23.1%, p < 0.001) and total body fat mass (4.4%, p = 0.02). (4) Conclusions: There were no significant differences in balance, lean mass or bone mass. The present study suggests that 12 weeks of WBV has the potential to improve SPM30, fat mass, TUG and 6MWT in postmenopausal women.

Aerobic exercise attenuates the effects of ovariectomy and sedentarism on body composition and food intake in female rats

“…However, in the present study, in addition to the 32.9% increase in visceral fat in OVX rats, there was also a 29.0% increase in the percentage of carcass fat (muscle) thus demonstrating a proportionality in the increase between visceral and muscle fat. This increase in body fat has been reported as being a consequence of aging in postmenopausal women, which could promote insulin resistance and an increased risk of chronic non-communicable diseases [1,2,4,5,8,11,12,16]. More importantly, the present study demonstrated that regular aerobic exercise reduced muscle fat in OVX rats to the levels of sedentary Sham rats.…”

“…Obesity is growing worldwide, being one of the main public health problems, especially in postmenopausal women [1][2][3][4]. Menopause is a natural aging process in women that promotes metabolic and body changes by increasing weight and body fat, which may increase the risk of cardiovascular diseases, obesity, diabetes, hypertension and cancer [2][3][4][5][6][7][8].…”

“…Aerobic exercises promote adaptations which are beneficial to the cardiovascular system by increasing energy expenditure and inhibiting weight gain, being a strategy for obesity control [2,4,7,9,[14][15][16]. However, postmenopausal and elderly women usually participate in aerobic exercises programs of very low intensity such as walking, which promote minor effects on body composition [14,17].…”

Impact of whole-body vibration exercise on physical performance and bone turnover in patients with monoclonal gammopathy of undetermined significance

“…However, results are inconclusive, particularly regarding direct associations of distinct treatment objectives with defined types of activity, intensity, duration and frequency [19] , [20] . Unfortunately, evidence confirming direct exercise-induced bone health is scarce [21] , [22] , [23] , [24] , [25] , [26] . Inconsistent findings may result from insufficient application of exercise training principles, particularly the principles of specificity, progression and overload [27] , [28] .…”

Effects of an Eight-Week Concurrent Training Program with Different Effort Character over Physical Fitness, Health-Related Quality of Life, and Lipid Profile among Hospital Workers: Preliminary Results

“…CRF was delineated with the 6M WT, a validated test used in the healthy population [22][23][24]. The 6M WT is a self-paced test in which participants are asked to walk laps of a straight, 30-m corridor as quickly as possible for six minutes.…”
