Onderzoek naar de rol van wijziging van de energiebalans op gezondheidsreacties bij chronische lymfatische leukemie (HIT-CLL)
This randomised control clinical trial aims to investigate the effects of exercise training and diet on physical and functional fitness and immunological and metabolic changes in adults with chronic lymphocytic leukaemia. Investigators will randomise participants to either 12 weeks of supervised/semi-supervised exercise only, exercise + nutritional guidance, or no exercise.

Gedetailleerde beschrijving
This study aims to perform a randomised control trial of exercise or exercise plus nutritional guidance on the physiological and immunological health of adults diagnosed with chronic lymphocytic leukaemia (CLL). Recruited participants will be randomised to either 12 weeks of an exercise-only program, an exercise-plus nutritional guidance program or a no-exercise control group. Fasting blood samples collected at Baseline and 12 weeks will measure absolute CLL cell counts, immune function, and inflammatory and metabolic biomarkers. A series of physical fitness assessments will be assessed at baseline and 12 weeks to determine physiologic reserve and resilience against external stressors. Additionally, participants will be asked to return 12 weeks after completing the intervention to assess the legacy effects of the intervention on the same physiological and blood-based biomarkers of health.

Inclusion Criteria:
- Confirmed diagnosis of CLL (including small lymphocytic leukaemia) as per the International Workshop on CLL Guidelines.
- Male or female ≥ 18 years of age
- Able to walk on a treadmill or cycle on an ergometer
- Pass the Physical Activity Readiness Questionnaires (PAR-Q and PAR-Q+)
Exclusion Criteria:
- Corticosteroid therapy initiated less than 7 days before study entry. Prednisone 10mg or less or equivalent is allowed. Topical or inhaled corticosteroids are permitted.
