Key result
High-intensity interval training significantly increased peak oxygen uptake compared to moderate exercise in heart transplant recipients (increase of 4.9 vs 2.6 mL/kg/min; p<0.001).
Why the study?
Does high-intensity interval training improve peak oxygen uptake and chronotropic response in stable heart transplant recipients compared to continued moderate exercise?
RCT (n=16)
Crossover
Does high-intensity interval training improve peak oxygen uptake and chronotropic response in stable heart transplant recipients compared to continued moderate exercise?
Absolute Event Rate: 4.9% vs 2.6%
p-value: p=<0.001
In stable heart transplant recipients, 12 weeks of high-intensity interval training safely improved peak oxygen uptake and chronotropic response more than moderate exercise.

Supports incorporating high-intensity interval training into post-transplant rehab; extends RCT evidence for higher-intensity exercise dosing.
Dall et al. (2014) conducted an RCT in Heart transplant recipients (n=16). High-intensity interval training (HIIT) vs. Continued moderate exercise (CON) was evaluated on Peak oxygen uptake (VO2peak) (p=<0.001). High-intensity interval training significantly increased peak oxygen uptake compared to moderate exercise in heart transplant recipients (increase of 4.9 vs 2.6 mL/kg/min; p<0.001).
