Hypothesis Testing Independent Samples T test Recent research has demonstrated that music-based physical training for older adults can improve balance and walking efficiency and reduce the risk of falls (Trombetti et al 2011). As part of the training, participants walked in time to music and responded to changes in the music's rhythm during a 1 hour per week exercise program. After 6 months, participants in the training group increased their walking speed and their stride length compared to individuals in the control group.
