简要总结
Aging is characterized by functional losses among which, the related to mobility and balance may be highlighted. Regular physical activity, including muscle strengthening exercises, is beneficial to a healthy elderly. Thus, this study aimed to verify the influence of 8 weeks-program of lower limbs strengthening exercises in the balance and functional mobility of physically active elderly. The investigators evaluated 18 women, with ages between 61 and 80 years. Balance assessment was performed using the Functional Reach Test (FRT), Timed Up and Go (TUG) test and Romberg test in stable or unstable soil. For muscular strengthening of the lower limbs, the workload was determined by the strength reached in the eight-repetition maximum test (8RM), applying progressive load increments between training sessions conducted (50% , 60% , 70% of 8RM), with the muscle strength being reevaluated in the fourth week of training, with subsequent adjustment of the load for the subsequent training. The training took place in two weekly meetings, in 40-minute sessions, during eight weeks. Data were analyzed using the paired-t test and ANOVA with repeated measures. Among 18 evaluated elderly women, 7 completed the 8 week training proposed. Decrease in TUG time (p = 0,035) and statistically significant increase in muscle strength were observed in all muscle groups trained (quadriceps, hamstrings, adductors and abductors). FRT (p = 0.170) was not significantly different after training. Therefore, strength training proposed was efficient in improving muscle strength in the lower limbs of irregular physically active elderly, impacting positively on functional gain gait. However, the gain in muscle strength was not enough to generate significant results in static balance probably due to the type of exercise performed as well as due being limited to muscle groups of the lower limbs.

Functional mobility
时间窗: The results were obtained at the end of the eight weeks of intervention
The TUG allows a quantitative assessment of gait and mobility, enabling the investigation of the effects of a particular intervention on these parameters (Van Iersel et al., 2008). The TUG is a sensitive test, is a good option of choice to be used as the primary outcome measure in clinical trials to improve gait and mobility (Van Iersel et al., 2008). It allows the researcher to observe the sitting balance of transfers from sitting to standing position and vice versa, as well as stability while walking and walking course changes. For the application of TUG has asked the elderly up from a chair without armrest from the recumbent position, wander around a distance of 3 meters safely and quickly, turn, return on the same route and the chair again with the back supported on back. Performance was assessed by timing the time required for the completion of the test. The time taken for the test is determining the risk for falls, classified as low, when the time spent on the test is less than
Risk of falls and Balance
时间窗: The results were obtained at the end of the eight weeks of intervention
To the risk of falls in the elderly, the Romberg test is an effective method, since its completion provides anteroposterior instability or increased body sway. For this test, in the standing position the participants remained with the feet together, aligned head and arms along the body. Then, it was requested that, keeping the position described, the participants close their eyes for a period of 30 seconds. Later, the same test was repeated, but on shaky ground when the participant was left standing position on a foam surface, requesting again the closing of the eyes. A procedure again observing the imbalance with time record in seconds, before its occurrence.
