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 .
3 Different types of strength training in older women.
The objective of the present study was to evaluate and compare the neuromuscular , morphological and functional adaptations of older women subjected to 3 different types of strength training . 58 , healthy women ( 67 ± 5 year ) were r and omized to experimental ( EG , n=41 ) and control groups ( CG , n=17 ) during the first 6 weeks when the EG group performed traditional resistance exercise for the lower extremity . Afterwards , EG was divided into three specific strength training groups ; a traditional group ( TG , n=14 ) , a power group ( PG , n=13 ) that performed the concentric phase of contraction at high speed and a rapid strength group ( RG , n=14 ) that performed a lateral box jump exercise emphasizing the stretch-shortening-cycle ( SSC ) . Subjects trained 2 days per week through the entire 12 weeks . Following 6 weeks of generalized strength training , significant improvements occurred in EG for knee extension one-repetition ( 1RM ) maximum strength ( + 19 % ) , knee extensor muscle thickness ( MT , + 15 % ) , maximal muscle activation ( + 44 % average ) and onset latency ( -31 % average ) for vastus lateralis ( VL ) , vastus medialis ( VM ) and rectus femoris ( RF ) compared to CG ( p<0.05 ) . Following 6 more weeks of specific strength training , the 1RM increased significantly and similarly between groups ( average of + 21 % ) , as did muscle thickness of the VL ( + 25 % ) , and activation of VL ( + 44 % ) and VM ( + 26 % ) . The onset latency of RF ( TG=285 ± 109 ms , PG=252 ± 76 ms , RG=203 ± 43 ms ) , reaction time ( TG=366 ± 99 ms , PG=274 ± 76 ms , RG=201 ± 41 ms ) , 30-s chair st and ( TG=18 ± 3 , PG=18 ± 1 , RG=21 ± 2 ) and counter movement jump ( TG=8 ± 2 cm , PG=10 ± 3 cm , RG=13 ± 2 cm ) was significantly improved only in RG ( p<0.05 ) . At the end of training , the rate of force development ( RFD ) over 150 ms ( TG=2.3 ± 9.8 N·s(-1 ) , PG=3.3 ± 3.2 N·s(-1 ) , RG=3.8 ± 6.8 N·s(-1 ) , CG=2.3 ± 7.0 N·s(-1 ) ) was significantly greater in RG and PG than in TG and CG ( p<0.05 ) . In conclusion , rapid strength training is more effective for the development of rapid force production of muscle than other specific types of strength training and by consequence , better develops the functional capabilities of older women
