Aerobic performance and morphological modifications after a 4 month physical activity training program in elderly women

Research clearly shows that physical activity (PA) is an important factor to develop and maintain good health and adequate body functions in older people. In this context, the purpose of this study was to determine aerobic performance and morphological modifications after a 4 month physical activity program (PAP) in elderly. METHODS Forty subjects divided in two groups (control, n=20; and experimental, n=20) were evaluated twice, at the beginning and after a 4-month-activity program period. This program called “+ age + health” consists of 3 week sessions of one hour each, based on walking and aerobic exercises. The control group had, at its first evaluation, the followings characteristics: average body mass 68kg±15, 28±5 BMI, 37%±5 body fat, 2.2kg±0.4 bone mass, 42%±9 lean body mass and did 129 repetitions ± 46 on a 2-Minute Step Test (2MST). The assessment of anthropometric and morphological variables was measured through an electrical bioimpedance scale (TANITA - BC 545). Aerobic endurance was evaluated from a 2MST.RESULTS In the control group only the percentage of body fat changed significantly, and increased over time. In the experimental group we found a positive relationship between PAP and the majority of morphological variables. The percentage of variation changed in: body fat (-4.3%±7.6, p=0.014), bone mass (2.4%±3.1, p=0.004) and 2MST (33.6%±63.1, p=0.023). In the remaining variables there were no significant modifications. The significant modification in 2MST after the activity period means that the aerobic performance can be improved in elderly, and attenuates the negative effects of age. Moreover, the benefits of PAP can be seen by positive alterations registered in lean body mass and in the percentage of body fat.

Quality of life in institutionalized elderly undergoing an active aging program

Living with quality is a growing concern of the old population. There is an increasing institutionalization of the elderly, and it is in this context that active aging programs assume relevance, allowing the elderly the contact with experiences that allow them to age with quality of life, by maintaining their autonomy and promoting their physical, mental and emotional well-being. This study aims to assess the quality of life of institutionalized elderly undergoing to an active aging program. Methods: We have developed a semi-experimental study that considers the quantitative methodology in which the following instruments were used to measure the quality of life: Eurohis-Qol-8 (Pereira, Melo, Gameiro, & Canavarro, 2011) and Whoqol-Old (Vilar et al., 2010), to which sociodemographic and clinical questions were added. Assessments were made in two different moments, before and after the intervention program, in a sample of 37 institutionalized elderly. Results: Concerning the assessment of quality of life related to health (Eurohis-Qol-8), significant higher scores were obtained in the second moment (p = 0.004). Regarding the quality of life related to the elderly significant better scores were also obtained in the second assessment (p = 0.001). Conclusions: The results obtained allow us to conclude that using either of the measuring scales of Eurohis-Qol-8 or Whoqol-old, there is a perceived improvement in quality of life in those using the active aging program. Thus, institutionalized elderly must be the main target in the design and implementation of active aging programs.
