Despite reductions in muscle mass and muscle strength in adults with CHD, the muscle strength per muscle mass relationship does not differ from controls

Abstract Background: Patients with CHD exhibit reduced isometric muscle strength and mass; however, little is known how these parameters relate. Therefore, the aim was to investigate relation between limb mass for patients in comparison age- sex-matched control subjects. Methods: Seventy-four (35.6 ± 14.3 years, women n = 22) 74 matched controls were included. Isometric elbow flexion, knee extension, hand grip assessed using dynamometers. Lean mass, reflecting skeletal arms legs dual-energy x-ray absorptiometry. Results: Compared controls, had lower grip, (6.6 1.8 kg versus 5.8 1.7 kg, p < 0.001) (18.4 3.5 15.9 3.2 0.001). There no difference achieved force per unit compared (elbow flexion 0.03 0.004 0.005 N/g, 0.5; 0.008 0.001 0.7; extension 0.027 0.06 0.028 0.5). For both groups, correlated strongly (patients r 0.86, 0.89), (patients, 0.84, 0.81), leg 0.64, 0.68). Conclusion: The relationship adults indicates that muscles have same efficiency as healthy controls.
