Description
Summary:Background: Individuals with PWS require marked caloric restriction and daily exercise to prevent morbid obesity. Lower energy expenditure compared to BMI-matched controls along with hypotonia, decreased muscle mass, and cognitive impairment make exercise particularly challenging for this population. Exercise guidelines include resistance training as an important component. Myokine responses to resistance exercise may have beneficial metabolic effects. Objectives: Determine if young PWS adults can perform a resistance exercise program. Evaluate myokine responses to acute resistance exercise in young adults with PWS and compare responses with age and BMI-matched controls. Methods: Each study group included 11 participants (7M/4F). Mean±SD ages were 30.7±4.6 and 30.1±4.3 years for PWS and controls (NS). BMI values were 28.3±4.3 and 28.2±4.2 kg/m 2 for PWS and controls, respectively (NS). Blood samples for glucose, creatine kinase (CK), lactate, hemoglobin A1c (HbA1C) and myokines were obtained before performing a program of eight resistance exercises lasting 45-60 minutes. Additional blood samples were drawn immediately after, and 30 and 60 minutes after completing the exercises. Myokines were assayed using a multiplex myokine panel (Merck Millipore). Paired t-test was used for comparing results for PWS vs controls. The unpaired t-test was used for comparing peak laboratory values with basal levels. Results: Basal levels (mean±SEM) of glucose, hemoglobin A1c, and lactate were similar for PWS and controls but CK was lower in PWS vs controls (62±16 vs 322±100 U/L, p
