Velocity walking test: Selective influences on physical functional performance for better tracking of older women.

OBJECTIVE: To examine the selective influences of changes in walking test capability on physical functional performance (COD speed, COD deficit, linear sprint speed, chair stand test, handgrip strength, and unloaded vertical jump) in community dwelling older women. METHODS: The performances of eighty women ((age, 64.7 ± 3.38 y; body mass, 66.3 ± 11.15 kg; height, 153.5 ± 5.71 cm, BMI, 28.08 ± 4.00 kg/m2) were assessed in the 6-m walk test, timed up and go test, chair stand test, handgrip strength, and unloaded vertical jump. The change of direction velocity (CODv) deficit (m.s-1) was calculated as TUG velocity - 6-m walk velocity. Estimation statistics were adopted, which focus on the effect size of the higher/lower, as opposed to significance testing. The bootstrap with 5000 replicates was used to obtain bias-corrected and accelerated 95% compatibility intervals (CI) of the point estimate of each effect RESULTS: There were large effects between faster older women compared to slower older women in COD velocity (TUG), chair stand test, and CODv deficit. On the other hand, we observed no influence of 6-m walk test performance on vertical jumps or the handgrip strength test. CONCLUSION: Strength and conditioning coaches and professionals involved with older women should consider the COD deficit (i.e., linear velocity minus change of direction velocity), as a complementary measure to provide an initial idea of the adequate pathway for exercise prescription and to track responses in older women.

Body weight multicomponent program improves power and functional capacity responses in older adults: A quasi-experimental study.

The aim of this study was to analyze the effects of multicomponent training with body weight on functional capacity response and power in aging persons. Twenty-seven active older women were assigned for convenience to control (active CG) or multicomponent training groups (MTG). The two groups exercised for 10 weeks, the active CG carried out the usual activities of the community service program, while the MTG followed a multicomponent training program. The countermovement and squat jump height (cm), medicine ball throwing distance (cm), time (s) to complete the tests: chair stand, timed up and go, and stair ascent and descent with 8 steps, and the total number of repetitions during 30 s of the tests: chair stand and arm curl were evaluated before (baseline) and after (post-training) the training period. For all analyses, we used estimation statistics, which focus on the effect size of the experiment/intervention, as opposed to significance testing. Changes over 10 weeks showed a large effect (d, >0.8) favoring the multicomponent training group compared to the active control group for all functional capacity performance and power variables (p ≤ 0.05). In conclusion, body weight multicomponent training is effective for improving basic functional capacity and upper and lower limb power abilities.
