Key result
Single leg cycling increases VO2max ~14% in organ transplant recipients, matching double leg cycling.
Why the study?
The contribution of cardiovascular, central, and peripheral factors in improving VO2max after endurance training has never been quantified in heart, kidney, and liver transplant recipients.
Does single leg cycling endurance training improve maximal oxygen uptake compared to double leg cycling in organ transplanted recipients?
Population
33 transplant recipients (13 HTx, 11 KTx, and 9 LTx)
Comparison
24 sessions of SL-ET vs DL-ET
Follow-up
24 sessions

May support single-leg cycling as alternative training in transplant recipients; hypothesis-generating for peripheral adaptations, needs randomized confirmation.
Does single leg cycling endurance training improve maximal oxygen uptake compared to double leg cycling in organ transplanted recipients?
Absolute Event Rate: 13.8% vs 18.6%
p-value: p=<0.001
Single leg cycling endurance training is as effective as double leg cycling in improving maximal oxygen uptake in organ transplant recipients, highlighting the role of peripheral factors in exercise limitation.
Torto et al. (2021) studied Organ transplanted recipients (heart, kidney, liver) (n=33). Single leg cycling endurance training (SL-ET) vs. Double leg cycling endurance training (DL-ET) was evaluated on Maximal oxygen consumption (DL-VO2max) (p=<0.001). Single leg cycling endurance training increased VO2max by 13.8% (p<0.001) in organ transplant recipients, proving as effective as double leg cycling (18.6% increase, p<0.001).
