Aerobic Exercise
BehavioralParticipants receive twice weekly supervised aerobic treadmill-based exercise sessions for five months. Session duration varies from 20 to 60 minutes, including warm-up, with exercise intensity ranging from 60 to 95% of peak heart rate. Maximal exercise capacity (VO2peak and peak heart rate) will be determined by the CPET performed by certified exercise physiologists at baseline.The exercise prescription will be sequenced so that the exercise intensity and -duration of each exercise varies within each week, leading to an accumulative increase in weekly exercise volume throughout the intervention. This intervention is also given to the Active Comparator group (i.e. non-cancer reference group)
