Exercises of dynamic stability under unstable conditions increase muscle strength and balance ability in the elderly

Falls are the leading cause of injury and injury-related death in the elderly. This study evaluated the effect of virtual reality gait training (VRGT) with non-motorized treadmill on balance and gait ability of elderly individuals who had experienced a fall. Fifty-six elderly individuals living in local communities participated in this study. Subjects who met the selection criteria were randomly divided into a VRGT group (n = 28) and a control group (n = 28). The VRGT group received VRGT with non-motorized treadmill for 50 min a day for 4 weeks and 5 days a week. The control group received non-motorized treadmill gait training without virtual reality for the same amount of time as the VRGT group. Before and after the training, the one-leg-standing test, Berg Balance Scale, Functional Reach test, and Timed Up and Go test were used to assess balance ability, and the gait analyzer system was used to evaluate the improvement in gait spatiotemporal parameters. In the VRGT group, the balance ability variable showed a significant decrease in the one-leg-standing test and a significant improvement in the Timed Up and Go test. With respect to spatiotemporal gait parameters, velocity and step width decreased significantly in the VRGT group (p < 0.05), and stride length and step length were significantly improved in the VRGT group (p < 0.05). VRGT with non-motorized treadmill has been shown to improve balance and gait ability in the elderly. This study is expected to provide basic data on exercise programs for the elderly to prevent falls.

Cut Points

We aimed to determine cut-points for muscle strength based on metabolic syndrome diagnosis. This cross-sectional analysis comprised data from 2 cohorts in Brazil (EpiFloripa Adult, n = 626, 44.0 ± 11.1 years; EpiFloripa Aging, n = 365, 71.6 ± 6.1 years). Metabolic syndrome was assessed by relative handgrip strength (kgf/kg). Metabolic syndrome was defined as including ≥3 of the 5 metabolic abnormalities according to the Joint Interim Statement. Optimal cut-points from Receiver Operating Characteristic (ROC) curves were determined. Adjusted logistic regression was used to test the association between metabolic syndrome and the cut-points created. The cut-point identified for muscle strength was 1.07 kgf/kg (Youden index = 0.310; area under the curve (AUC)) = 0.693, 95% CI 0.614–0.764) for men and 0.73 kgf/kg (Youden index = 0.481; AUC = 0.768, 95% confidence interval (CI) = 0.709–0.821) for women (age group 25 to < 50 years). The best cut-points for men and women aged 50+ years were 0.99 kgf/kg (Youden index = 0.312; AUC = 0.651; 95% CI = 0.583–0.714) and 0.58 kgf/kg (Youden index = 0.378; AUC = 0.743; 95% CI = 0.696–0.786), respectively. Cut-points derived from ROC analysis have good discriminatory power for metabolic syndrome among adults aged 25 to <50 years but not for adults aged 50+ years. Novelty: First-line management recommendation for metabolic syndrome is lifestyle modification, including improvement of muscle strength. Cut-points for muscle strength levels according to sex and age range based on metabolic syndrome were created. Cut-points for muscle strength can assist in the identification of adults at risk for cardiometabolic disease.

The increasing number of elderly and elderly life expectancy is a challenge for health workers. Decreased cardiac endurance, muscle strength and increased incidence of inflammation will occur in the elderly as we get older. health cardio exercises series-I is an aerobic exercise that has moderate intensity and is carried out for 30 minutes, research is needed to analyze the effect on cardiac endurance, muscle strength and decrease plasma TNF-? levels in the elderly. Research design with experimental method, pre-test and post-test design approach. The study was conducted for 4 weeks on 25 samples which were divided into 3 groups of frequency of health cardio exercises series-I to measure endurance of the heart. A 6-minute road test and muscle strength were used for hand grip strength dynamometer, test back and leg dynamometer. Measurement of plasma TNF-? levels is carried out using the Elisa method. The data was then analyzed using paired t-test to see differences before and after health cardio exercises series-I. The results showed health cardio exercises series-I performed 3x / mg can increase the heart's endurance compared to the frequency of 4x / mg and 5x / mg (-16.11 vs 15.62 vs -47.62 meters). health cardio exercises series-I frequency of 3x / mg and 4x / mg can increase back muscle strength (p-value = 0.019, p <0.05) and the frequency of 5x / mg can increase the strength of attractive shoulder muscles. (p-value = 0.033, p <0.05). Health cardio exercises series-I performed 3x / mg, 4x / mg and 5x / mg did not have a significant effect on plasma TNF-? protein expression in the elderly (0.506 vs 0.856 vs. 0.382, p <0.05). It is suggested that the elderly can do I-1 series heart exercise with a frequency of 3x / mg to increase the heart's lung endurance and back muscle strength, a health cardio exercises series-I 4x / mg series to increase muscle strength of the back back, a series of health cardio exercises series-I frequency of 5x / mg to increase attractive shoulder muscle strength.

INTRODUCTION: Ageing has become a huge public health challenge due to the need to find solutions for improving quality of life. OBJECTIVE: This study aimed to assess quality of life, muscle strength, balance and physical capacity among elderly practitioners and non-practitioners of physical activity. MATERIALS AND METHODS: An observational, cross-sectional study was carried out involving 74 elderly individuals in the city of Santos (state of São Paulo, Brazil), divided into two groups: practitioners and non-practitioners of physical activity. The International Physical Activity Questionnaire was used for the classification of the participants. The generic SF-36 questionnaire was used to assess quality of life. The Berg scale was used for the analysis of balance. Dynamometry was used for the muscle strength test. The six-minute walk test was used for the assessment of physical capacity. RESULTS: Significant differences were found between elderly practitioners and non-practitioners of physical activity regarding quality of life (p = 0.001), muscle strength (p = 0.001), balance (p = 0.001) and physical capacity (p = 0.001). The data also showed that aspects of quality of life were strongly correlated with physical capacity among the non-practitioners of physical activity (r = 0.741). CONCLUSION: Elderly individuals in the city of Santos (Brazil) who practice physical activity have better quality of life, muscle strength, physical capacity and balance in comparison to those who do not practice physical activity.
