Molecular Mechanism of Exercise in Cirrhosis
This study aims to investigate the effects of 12 weeks of resistance or endurance exercise on patients with cirrhosis. Cirrhotic patients are prone to muscle loss (sarcopenia) and ammonia build up due to liver dysfunction. The liver which in healthy patients is able to process ammonia through ureagenesis is unable to do so in cirrhosis and ammonia is taken up either by the brain causing confusion or the skeletal muscle causing muscle loss or sarcopenia. Primary sarcopenia occurs in older individuals and can be mitigated by exercise. Secondary sarcopenia occurs in response to disease such as cancer, chronic kidney disease, multiple sclerosis, and cirrhosis of all etiologies. Resistance exercise is an excellent stimulator for muscle protein synthesis and is widely used to build muscle mass and strength but has little benefit to cardiovascular function. Endurance exercise has shown to be safe in cirrhosis however there is no set prescription for cirrhosis as there is for other disease. Endurance exercise is known to promote improved cardiovascular health, improve fatigue, and generates less ammonia build up than resistance exercise. In patients with low muscle mass it is possible that endurance exercise alone will be enough to improve muscle mass. There have been few studies on exercise and cirrhosis, those that exist have shown benefits with endurance exercise. However there are even more limited studies on resistance exercise and few to no studies on the molecular mechanisms behind exercise in cirrhosis. Study visits are described fully in the protocol and consent form. After passing a screening visit patients will undergo a maximal exercise/fitness test (pre-baseline test) and other body composition measurements. After the screening and pre-baseline visit randomization will occur (2:2:1 endurance, resistance, or SOC) arrangements will be made to have the appropriate exercise equipment given to patients. Once the exercise equipment has arrived a baseline study visit will occur. After the baseline visit the endurance exercise group will cycle 3 days per week for 60 minutes under the supervision of the study team. The resistance exercise group will perform a whole body resistance workout 2 days per week for approximately 60 minutes under the supervision of a study team member.
Patients in all groups will have the fitness test repeated at weeks 4, 8 and 12. After the 12 weeks of exercise the baseline visits will be repeated and after 2 weeks patients will complete one final fitness test to examine the effects of de-training.
