![]() Therefore, alternative strategies with a lower risk of injury have been sought and usually included in the medical advice, such as walking programmes. However, arduous bone stress induced by vigorous weight-bearing activities can increase the risk of injuries, particularly in the elderly. Aerobics, weight bearing and resistance exercises were all effective increasing bone mass density. Physical exercise is considered as an effective strategy, frequently recommended in general practice, for the prevention and management of postmenopausal osteoporosis. The major determinants of bone fractures are falls, bone fragility, loss of balance and decrease of lower limb strength. The 8-month course of vibratory exercise using a reciprocating plate is feasible and is more effective than walking to improve two major determinants of bone fractures: hip BMD and balance.īone fracture is among the commonest and most expensive health problems in the population, particularly in postmenopausal women. Balance was improved in the WBV group (29%) but not in the Walking group. In contrast, the BMD at the lumbar spine was unaltered in both groups. ResultsĪfter 8 months, BMD at the femoral neck in the WBV group was increased by 4.3% ( P = 0.011) compared to the Walking group. ANOVA for repeated measurements was adjusted by baseline data, weight and age. cm -2) were measured using dual-energy X-ray absorptiometry and balance was assessed by the blind flamingo test.Each walking session was 55 minutes of walking and 5 minutes of stretching. Each vibratory session included 6 bouts of 1 min (12.6 Hz in frequency and 3 cm in amplitude with 60° of knee flexion) with 1 min rest between bouts. Both experimental programmes consisted of 3 sessions per week for 8 months. Twenty-eight physically untrained post-menopausal women were assigned at random to a WBV group or a Walking group. The aim was to compare the effects of WBV using a reciprocating platform at frequencies lower than 20 Hz and a walking-based exercise programme on BMD and balance in post-menopausal women. ![]() A few studies have shown recently the effectiveness of the up-and-down plate for increasing Bone Mineral Density (BMD) and balance but the effectiveness of the reciprocating plate technique remains mainly unknown. There are two currently marketed vibrating plates: a) the whole plate oscillates up and down b) reciprocating vertical displacements on the left and right side of a fulcrum, increasing the lateral accelerations. Whole-body vibration (WBV) is a new type of exercise that has been increasingly tested for the ability to prevent bone fractures and osteoporosis in frail people.
