Effects of different weekly frequencies of dance on older adults' functional performance and physical activity patterns
Date of this Version
This study examined the effect of dancing on the functional performance and physical activity levels of 45 retirement village residents participating in either a control (n = 13), Once a Week (n = 18) or Twice a Week (n = 14) dance group for 12 weeks. Changes in functional performance were assessed by three functional tests (30 s bicep curl, Timed Up and Go and the Four Square Step Test) as well as the Late Life Function Index. The CHAMPS questionnaire was used to estimate the weekly total as well as moderate and greater intensity energy expenditure and associated frequency counts. Once a Week dancing resulted in significantly greater improvements in Four Square Step Test and estimated total energy expenditure than the control group; whereas the Twice a Week group significantly improved their Late Life Function Index (Total and Basic Lower Extremity) scores significantly more than the control group (p0.05). These results further support the belief that even once a week exercise (including dancing) can produce some significant benefits for older adults.
