Study Summary
PURPOSE: The purpose of the study is to determine the effects of 12-weeks of exercise training on physical reserve, as measured by aerobic capacity, strength and physical function, in patients with CLL. Further, it is our aim to assess relationships with changes in physical reserve and resilience to the patient's cancer, as measured by immune cell counts, tumor cell killing and antibacterial functions. DESIGN: Subjects will have confirmed treatment naïve CLL. Subjects will be assigned to either a 12-week control (no supervised exercise) or an intervention (HIIT) group. Before and after the 12 week program subjects will undergo several tests including: 1) a maximal treadmill test, 2) body composition, 3) muscle strength and endurance, 4) physical activity levels, 5) blood measures (e.g. immune and inflammatory functions). Subjects in the HIIT group will complete a 12-week supervised exercise training program consisting of HIIT and strength training. DATA ANALYSES \& SAFETY ISSUES: This is a pilot study, with the goal of assessing whether exercise training causes a change in aerobic fitness (VO2peak), muscle function, and immunological measures. Vo2peak will be measured by a cardiopulmonary exercise test, muscle function will be measured by strength tests, and immunological functions will be measured from blood samples. For outcomes, group change differences from baseline to 12-weeks will be compared by ANCOVA. The data will be used to provide power calculations for future grant proposals. High Intensity Interval Training is a very safe exercise modality. The regular use of vigorous intensity exercise intervals have been used extensively in exercise training. In fact, the exercise intervals will start at levels lower and will be of shorter duration than were used during the maximal exercise test. They will then be carefully and slowly made to be more challenging as each subject is able to safely tolerate. HYPOTHESIS: The investigators hypothesize that HIIT will be
