The EAA intervention is designed to attenuate muscle loss, improve functional outcomes, and enhance quality of life. Data analyses will focus on shorter-term, longer-term results, and change over time. Preliminary analyses will employ descriptive statistics to understand the nature of the data and ensure that data distributions are appropriate for the statistical tests employed. Chi-square tests and analyses of variance, as appropriate, will be conducted to evaluate the equivalence of continuing participants vs. dropouts on demographic, medical history, and recent levels of dependent variables.
