There is growing interest of researchers in physical performance tests such as walking speed (WS) in the older adult population. This study examined the association between lower extremity functional strength (LEFS) and WS, accounting for potential confounders, and the extent to which LEFS significantly predicts WS in 72 older adults living in a senior housing facility. Participants completed LEFS and WS measures. We observed strong associations between LEFS and WS, and a significant regression equation was found with LEFS and height emerging as significant predictors of WS. This suggests that an equation using LEFS and height could be used as a surrogate to predict WS in this age group. [ABSTRACT FROM AUTHOR]

Introduction. To evaluate the acute effect of resistance exercise performed at different intensities (moderate and vigorous) on urine loss in older women with mixed and stress urinary incontinence. Methods. The total of 16 older women with urinary incontinence underwent 2 sessions of resistance exercises involving dif- ferent muscle groups. In a balanced crossover design, 1 of the 2 exercise intensities (12 or 6 repetitions maximum, RM) was applied in each session. The pad test was used to assess urine loss in the 2 sessions, with a weight increase of 2 g as the criterion. Differences in the pad test results between the sessions were compared with the use of the Wilcoxon test. Results. The mean pad weight was 0.69 ± 0.94 g at the intensity of 12RM and 0.50 ± 0.53 g at 6RM. In accordance with the cut-off adopted (2 g), only 2 of the 16 women lost urine. No significant difference in the pad test results (p = 0.975) was observed between the 2 resistance exercise intensities. Conclusions. Resistance exercise performed at different intensities (moderate and vigorous) did not cause urine loss in older women with urinary incontinence. [ABSTRACT FROM AUTHOR]

Objective: This study investigated the chronic effects of different rest intervals (RIs) between sets on dynamic and isometric muscle strength and muscle activity. Design: We used a repeated-measures design (pretraining and posttraining) with independent groups (different RI). Twenty-one resistance-trained older women (66.4 ± 4.4 years) were randomly assigned to either a 1-minute RI group (G-1 min; n = 10) or 3-minute RI group (G-3 min; n = 11). Both groups completed 3 supervised sessions per week during 8 weeks. In each session, participants performed 3 sets of 15 repetitions of leg press exercise, with a load that elicited muscle failure in the third set. Fifteen maximum repetitions, maximal voluntary contraction, peak rate of force development, and integrated electromyography activity of the vastus lateralis and vastus medialis muscles were assessed pretraining and posttraining. Results: There was a significant increase in load of 15 maximum repetitions posttraining for G-3 min only (3.6%; P < 0.05). However, posttraining results showed no significant differences between G-1 min and G-3 min groups for all dependent variables (P > 0.05). Conclusions: The findings suggest that different RIs between sets did not influence dynamic and isometric muscle strength and muscle activity in resistance-trained older women.

The purpose of this study was to analyze the effects of static stretching on functional capacity of older women. Thirty-one older women (68.2 ± 7.4 yrs) were randomly assigned to two groups: Control Group (n = 16) and Training Group (n = 15). Functional capacity was assessed by a motor test battery and the global functional fitness index (GFFI) calculated by summing the scores of all motor tests. Maximal voluntary contraction was evaluated during unilateral isometric knee extension. After 8 wks of training, the TG had significantly (P<0.001) better flexibility levels (59.0 ± 9.9 cm) than the CG (49.5 ± 10.1 cm). The TG also improved the GFFI overall classification, which changed from "Fair" (200-299 points) to "Good" (300-399 points), while the CG remained classified as "Fair". No difference was observed between groups for the other variables. Thus, the findings indicate that static stretching training is effective in improving flexibility and general functional activities in older women. [ABSTRACT FROM AUTHOR]

The article discusses a study which analyzed the effect of eight weeks of resistance training (RT) on systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP) and heart rate (HR) in elderly women with no hypertension. RT is commonly used for older adults to reduce the harm of aging in the neuromuscular system. It is also confirmed to be a useful training to encourage adaptations in the cardiovascular system of older women with no hypertension.

The article discusses a study on the acute effect of different weight exercise intensities in the muscular performance of trained older women. The researchers determined a load related to 15 maximum repetitions (RM) in the leg press. The results show that a reduction of 10 percent in the load corresponding to 15 RM presents a significant effect on the sustainability of number of repetitions between sets and training volume.

The article offers information on a study on the muscle performance effects of varied rest intervals between sets of leg press exercises performed by untrained elderly women. The study observes the effects of using 1 minute and 3 minute rest intervals between three sets of leg press exercises. Results show that the total volume of sessions with the 3 minute rest interval was higher than when the 1 minute rest interval was used in terms of number and sustainability of repetitions.

We analyzed the effect of an 8-week strength training (ST) program on the rate of force development (RED) and eUctromyographic activity (EMG) in older women. Seventeen women (M age = 63.4 years, SD = 4.9) without previous ST experience were randomly assigned to either a control (n= 7) or training (n = 10) group. A leg-press isometric test was used for assessment. ST (three sessions/ week, three sets of 10--12 repetition maximum, five different exercises) induced significant increases (p < . 05) on peak RFD (48.4%) and on RFD and EMG ofvastus medialis at time intervals of 0-50, 0-100, 0-150, and 0-200 ms (41.1-69.2% and 43.8- 64.3%, respectively). Therefore, ST resulted in favorable changes in neuromuscular responses in older women. [ABSTRACT FROM AUTHOR]
