BELLARMINE UNIVERSITY, LOUISVILLE, KY TAI CHI + CYCLING ARTICLEDESIGNSUBJECTS INTER- VENTIONS OUTCOME MEASURES CONCLUSIONS Caminiti et al, 2003 RCT (Level 1b)  N=60  Age= 73.8 yrs.  CHF  Exercise training group: cycling or walking  Combined training group: Tai Chi + cycling or walking  6MWT  MacNew QLML QOL question- naire  QOL sign. improved (p=0.026)  6MWT distance sign. increased (p=0.001)  SBP sign. decreased

BELLARMINE UNIVERSITY, LOUISVILLE, KY Caminiti et al, 2003 METHODS Exercise training: 30 min of cycling or walking at 60-70% VO 2 max Combined training: –Tai Chi for 30 min 2x/week –Cycling or walking for 30 min 2x/week 4 sessions/week for 12 weeks

BELLARMINE UNIVERSITY, LOUISVILLE, KY Caminiti et al, 2003 RESULTS QOL (MacNewQLML) significantly improved (esp social and emotional) (p=0.026) 6MWT distance increased from m to m (p=0.001) SBP significantly decreased (p=0.025)

BELLARMINE UNIVERSITY, LOUISVILLE, KY CYCLING ARTICLEDESIGNSUBJECTSINTERVENTIONS Smart et al, 2004 RCT (Level 1b)  N=30  Age=63.8 yrs  CHF  Weeks 1-16: cycling  Weeks 8-16: cycling + strengthening  Weeks 16-52: HEP only Giannuzzi et al, 2003 RCT (Level 1b)  N=90  LVEF < 35%  Exercise group: cycling  Control group: educational support Belardinelli et al, 1999 RCT (Level 1b)  N=94  Mean age: 59 yrs  CHF  LVEF < 40%  1st phase: 3x/week (cycling), 60% VO 2 max  2nd phase: 12 months, 2x/ week (cycling), 60% VO 2 max  Control group: no exercise

BELLARMINE UNIVERSITY, LOUISVILLE, KY CYCLING ARTICLE OUTCOME MEASURES CONCLUSIONS Smart et al, 2004  MLHFQ  Peak VO 2  QOL improved (p=0.1)  Peak VO 2 sign. improved (p=0.001) Giannuzzi et al, 2003  6MWT  QOL assessment  6MWT distance increased by 20%  LVEF increased 16%  SBP and RPP decreased  O 2 uptake increased at ventilatory threshold and peak exercise Belardinelli et al, 1999  MLHFQ  VO 2  Peak O 2 uptake improved 18% (p=0.01)  Ventilatory threshold improved 30%  MLHFQ sign. improved (p=0.001)

BELLARMINE UNIVERSITY, LOUISVILLE, KY Giannuzzi et al, 2003 METHODS Functional eval at baseline and 6 mo FU Exercise group: –30 min cycle ergometer > 3x/wk at 60% of peak VO 2 –> 30 min daily walk and calisthenics Control group: –Educational support

BELLARMINE UNIVERSITY, LOUISVILLE, KY Giannuzzi et al, 2003 RESULTS Ejection fraction increased in exercise group by 16% SBP and rate-pressure product at rest decreased slightly in exercise group O 2 uptake increased at ventilatory threshold and at peak exercise 6MWT distance increased by 20%

BELLARMINE UNIVERSITY, LOUISVILLE, KY Conclusion Research has not yet compared effects of cycling versus Tai Chi on patients with CHF Both resulted in improved QOL, 6MWT distance and VO 2 max Consider incorporating both interventions into POC for patients
