title: Effects of dance interventions on cardiovascular risk with ageing: Systematic review and meta-analysis.
abstract: BACKGROUND
  Exercising, including dancing, has been recommended to improve cardiovascular health of older people. Herein, we conducted a systematic review and meta-analysis verifying the effects of dance interventions on cardiovascular risk (CVR) in the elderly, comparing dancers to non-exercise controls and other types of exercise, in randomised (RCTs) and non-randomised control trials (nRCTs). Primary/Secondary outcomes: peak oxygen consumption (VO2peak)/anthropometric measurements (body weight, BMI), and lipid profile.
  
  
  METHODS
  Data Sources: MEDLINE, Cochrane Wiley, Clinical Trials.gov, PEDRO and LILACS databases.
  
  
  METHODS
  RCTs and nRCTs comparing elderly before and after dance interventions with non-exercising controls and/or practitioners of other types of exercise. Two independent reviewers extracted data and assessed the quality of included studies.
  
  
  RESULTS
  A total of 937 articles were retrieved, 64 full texts were assessed for eligibility, and 7 articles met the inclusion criteria. Pooled mean differences between intervention and control were calculated by random-effects model. VO2peak improved in favour of dancers (3.4mLkg-1min-1, 95%CI: 1.08, 5.78, I2=71%), compared to non-exercise controls. No differences were found between dance and other exercises. Body weight and BMI were not altered by dance interventions.
  
  
  CONCLUSIONS
  Dance interventions may increase VO2peak compared to non-exercising controls. Results also indicate it is as effective as other types of exercise in improving aerobic capacity of the elderly. Dancing might be a potential exercise intervention for improving cardiorespiratory fitness and consequent CVR associated with ageing. Proper reporting on adverse events is needed to base the benefits of dancing for the older on both efficacy and safety of the interventions.
