Filter by:The elderly population is increasing at worldwide. The need of health promotion and maintenance for elderly adults has become a critical issue. According to a national investigation in 2017, the number of people over 65 years old accounts for 13.33% of the total population and would reach 20.1% by 2050. Muscle strength and functional performances of upper limbs play an important role in most daily activities in elderly adults. However, with aging, the muscle strength of upper extremities could be affected and decrease the functional performances of daily living. Vibration exercise can be used to induce the muscle contraction and motor control in lower limbs for people with neuromuscular disorders. Few studies have investigated the training effects on muscle strength and functional performances of upper limbs for elderly adults。Therefore, appropriate training devices and exercise programs to facilitate the muscle strength and functional performances of upper limbs in elderly people would be needed for clinical therapists. Therefore, the purpose of this study was to develop a vibration training device and investigate the training effects on muscle strength and functional performances of upper limbs in elderly people. This study will recruit 44 elderly adults, evaluating the muscle strength and functional performances of upper limbs before and after interventions. All subjects will be randomized assign to experimental and control groups; the experimental group will perform 30mins/ section, three times weekly for 8 weeks vibration training, and the control group will receive regular exercise training at same time. Two-way ANOVA with repeated measure will be applied to analyze the training effects and difference in the muscle strength and functional performances of upper limbs between two groups. SPSS version 18.0 statistical software will be used. The α level for statistical significance is set at 0.05.
Falls and fractures are serious and costly events for elderly individuals: they cause functional impairments, increase mortality and contribute to huge healthcare costs for the society. The number of falls, and following consequences, are expected to increase in society as the proportion of the elderly population will increase, therefore it is crucial to be able to detect and prevent falls and fractures in the population. The investigators have previously published results that objective measurements of postural balance can predict fall risk in 70-year-olds in Umeå and subsequently investigated whether balance can be improved through 4-week balance exercise program. However, preliminary results suggest that the frequency and duration of exercise should be longer than 3 times a week for 4 weeks to produce effects. Furthermore, there is also evidence indicating a link between muscle weakness and fall risk in elderly subjects, while research findings show that it is possible for older individuals to influence muscle strength and muscle mass with resistance exercise. Functional strength training can also positively influence the balance. In this context, the investigators aim to investigate whether a 10-week resistance exercise program may positively affect balance, muscle strength, muscle mass and physical function, with the aim of preventing future falls and fractures in the population.
The aim of this study is evaluate the effect of whey protein supplementation on muscle mass preservation, improvement of strength and quality of life, and inflammatory parameters in patients with heart failure NYHA I or II followed by a cardiac rehabilitation program.
Thus, the aim of the current study is to assess the influence of vitamin D deficiency and, consequently, of serum calcium deficiency in the body composition, muscular activity, bone mineral density, fatigue, and exercise tolerance of CD patients. Secondly, it also aims to determine the impact of vitamin D supplementation on this population.
