Summary
Brief summary (as posted)
PURPOSE: The purpose of the study is to determine the effects of 16-weeks of exercise training, as measured by aerobic capacity, strength and physical function, and body composition, in patients with Chronic Lymphocytic Leukemia (CLL). DESIGN: Subjects will have confirmed treatment naïve CLL. Subjects will be assigned to either a 16-week control group (no supervised exercise) or an intervention group of Resistance Training (REx). Before and after the 16-week protocol, patients will undergo several tests including: 1) a maximal cycle ergometer test, 2) Body Composition, 3) Muscle strength, 4) physical activity levels, 5) blood measures (e.g. immune and inflammatory functions). DATA ANALYSES \& SAFETY ISSUES: For outcomes, group change differences from baseline to 16-weeks will be compared with ANCOVA. Resistance training is a very safe exercise modality already studied in other cancer patients. The regular use of vigorous-intensity exercise has been used extensively in exercise training. It will always be respected for each subject's safety tolerance while challenging. HYPOTHESIS: The investigators hypothesize that the protocol will be feasible exercise interventions for people with CLL and will improve health and fitness markers.

- Resistance Exercise Training
- description
- Patients in the REx program are submitted to resistance machine exercises for the major muscle groups aiming to achieve the intensity of 80% of 1-Repetition Maximum (1-RM). A warmup and cool down of 10 and 5 minutes, respectively, were included in each session aiming workloads of 60%-85% of peak heart rate (HRp). Enrolment through the REx program resistance machines will be conducted from major muscle groups to minor muscle groups, from polyarticular to monoarticular exercises, and alternating between agonist and antagonist contraction according to the following laydown: Leg Press -\> Leg Curl -\> Leg Extension -\> Chest Press -\> Latissimus Pulldown -\> Shoulder Press -\> Triceps Extension -\> Biceps Curl -\> Abdominal Crunch.
