研究概览
简要总结
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.
详细描述
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 CLL and without any prior treatment.
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 Cardiopulmonary Exercise Test with Electrocardiogram (CPET+ECG) maximal cycle ergometer test, 2) a dual-energy X-ray absorptiometry (DEXA) Body Composition test, 3) a Muscle strength test with dynamometry, 4) a characterization of physical activity (PA) levels with accelerometry, and 5) blood measures (e.g. immune and inflammatory functions). The REx group will undertake a strength-based type of training with intensities near 80% of 1-Repetition Maximum (1-RM), with individual supervision (personal training approach).
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. It is also expected to have a positive correlation between physical fitness improvement and blood and immunologic parameters.

盲法说明
Clinical evaluation is performed in invited hospitals, physical activity evaluation is performed by the outcomes assessor in Faculty of Sport of University of Porto. The investigator is the person who will conduct the intervention, and he's the one that will know what protocol is assigned to each patient, but without knowing the results from clinical and physical fitness evaluations.
