Recent studies have reported that high-intensity resistance training improves physical function; however, all patients found it difficult to perform high-intensity resistance training. Radio calisthenics, considered as therapeutic exercises to promote health in Japan, are simple exercises that can be performed regardless of age and help move the muscles and joints of the whole body effectively according to the rhythm of radio. We investigated the efficacy of radio calisthenics for muscle mass in patients with type 2 diabetes in this retrospective cohort study.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Research design and methods<\/jats:title>\n                  <jats:p>A total of 42 hospitalized patients with type 2 diabetes were recruited. The skeletal muscle mass index (SMI, kg\/m<jats:sup>2<\/jats:sup>) was calculated as appendicular muscle mass (kg) divided by height squared (m<jats:sup>2<\/jats:sup>). We defined the change of SMI as the difference of SMI between the beginning and end of hospitalization.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Among 42 patients, 15 (11 men and 4 women) performed radio calisthenics. Body weights of both radio calisthenics exercisers and non-exercisers decreased during hospitalization. The change of SMI was significantly lesser in radio calisthenics exercisers than in non-exercisers (7.1\u00b11.4\u2009to 7.1\u00b11.3, \u20130.01\u00b10.09 vs 6.8\u00b11.1\u2009to 6.5\u00b11.2, \u20130.27\u00b10.06\u2009kg\/m<jats:sup>2<\/jats:sup>, p=0.016). The proportion of decreased SMI was 85.2% (23\/27 patients) in non-radio calisthenics exercisers, whereas that in radio calisthenics exercisers was 46.7% (7\/15 patients).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>Radio calisthenics prevent the reduction of skeletal muscle mass.
