A carefully planned resistance training program improves strength, fitness and depressive symptoms for a woman with type 2 diabetes

Abstract

Depression in type 2 diabetes (T2D) is estimated at 50% vs 18% among US adults, and markers of inflammation, which are tightly linked to hyperglycemia, are 5- to 50-fold higher in adults with T2D. Although lifestyle modifications are recommended for managing diabetes, resistance training (RT) is not commonly considered. This case report examined the practicality of implementing a structured RT protocol in a highly sedentary woman with T2D and depressive symptomology and assessed changes in strength, fitness, depression, and inflammation. The 59-year-old participant (body mass index: 38.1 kg/m2) was diagnosed in 2015. She had hypertension and bronchial asthma, was highly sedentary, and was clinically depressed based on validated measures: The Center for Epidemiological Studies Depression (CES-D) questionnaire and the Profile of Mood States (POMS) questionnaire. She had quit smoking 6 months earlier. The estimated 1RM guided the exercise prescription that used progressive overload to improve strength and promote the accretion of lean body mass. All exercise sessions (~45 minutes duration; 3× weekly) were supervised by trained personnel. After 8 weeks, total strength improved 135%. Heart rate was reduced by 14%, and depression symptomology fell into normal ranges. Although RT improved strength, fitness, and depressive symptomology, RT did not improve HbA1c, HOMA-IR, or inflammation emphasizing the need for a comprehensive treatment strategy. Simple assessments can be performed to determine the fitness and mental health of individuals with T2D, and incorporating an exercise prescription to standard care to address these key health determinants will empower patients to actively engage in their health care.
