Conclusion Plyometric training is a feasible and safe training option with potential for improving various performance , functional , and health-related outcomes in older persons
Background The aging process is associated with a progressive decline of neuromuscular function , increased risk of falls and fractures , impaired functional performance , and loss of independence .
Plyometric training may mitigate or even reverse such age-related deterioration ; however , little research on the effects of plyometric exercises has been performed in older adults .
Objective The objective of this systematic review was to evaluate the safety and efficacy of plyometric training in older adults .
The Osteogenic Effect of Impact-Loading and Resistance Exercise on Bone Mineral Density in Middle-Aged and Older Men: A Pilot Study
Background : Regular exercise has been recommended as a potential strategy to counteract the age-related bone loss experienced by men ; however , the optimal exercise prescription is not known . Objective : To perform a pilot study to examine the osteogenic effect , safety and feasibility of a combined program of upper body resistance exercise and two doses of impact-loading exercise on bone mineral density ( BMD ) of middle-aged and older men . Methods : Forty-two community-dwelling men aged 50 - 74 years were r and omly assigned to either an exercise program of combined upper body resistance exercise and either high-dose impact-loading ( HI ; 80 jumps per session ) or moderate-dose impact-loading ( MOD ; 40 jumps per session ) or a control ( CON ) group . The 9-month intervention involved 4 sessions each week : 2 supervised clinic-based and 2 home-based . BMD of the lumbar spine , femoral neck , total hip , trochanter and whole body as well as lean and fat mass were assessed at baseline and 9 months by dual-energy X-ray absorptiometry . Bone turnover markers , hormone levels , physical function and muscle strength were also assessed . Results : Following 9 months of training , significant differences in BMD among groups were found at the total hip ( p = 0.010 ) and trochanter ( p = 0.047 ) with BMD in the MOD group decreasing relative to the HI group . Although not significant , the HI group consistently preserved BMD , whereas BMD of the MOD and CON groups declined at the hip sites . Mean change for all groups at all skeletal sites was approximately within ±1 % . There was no change in bone turnover markers . There were no adverse events as a result of the intervention ; however , overall attendance for the HI and MOD groups was 53 % ( clinic : 68 % , home : 38 % ) and 65 % ( clinic : 74 % , home : 55 % ) , respectively . Conclusions : This study indicates that while impact-loading exercise can be safely undertaken in middle-aged and older men , the current combined program did not elicit significant improvements in BMD
