Adherence, Viability, Clinical Evolution and Therapeutic Efficacy in Patients Undergoing Bone Marrow Transplantation

The Aerobic Exercise Group will perform a cycle ergometer for 15 consecutive minutes with a load adjusted to maintain heart rate (HR) between 65-75% of the maximum HR predicted for age (HRmax = 200-age). Peripheral oxygen saturation will be controlled and, upon a sustained drop (\> 2 minutes after load reduction) below 90%, the session will be interrupted. The subjective feeling of tiredness in the legs and shortness of breath will be constantly monitored and if values equal to or greater than 8 (0-10) occur, the exercise will be stopped.

The Anaerobic Exercise Group will perform muscular strength training using maximum strength, where the contraction time should not exceed 20 seconds. For the upper limbs, the overload used will be through the use of an elastic band, with guidance for the patient to perform the shoulder external rotation exercise, elbow flexion exercises and open row rowing exercise. For the lower limbs, bridge movements, lunges and sit-up exercises will be performed with a maximum of 15 repetitions, and overload with ankle weights or dumbbells can be used in addition to body weight. The muscle contraction should lead the patient to a state of muscular fatigue and if the objective is not achieved, the exercise will be adapted to require greater strength from the patient so that he or she can reach maximum strength.

Mixed Exercise Group will perform the exercises by alternating between aerobic and anaerobic overload, in a 1:1 ratio until the end of the physical rehabilitation program, following exactly the same protocols described previously (alternating one session of the aerobic protocol and in the following session the anaerobic protocol).
