The Critical Role of Oxidative Stress in Sarcopenic Obesity
Table 1
Diagnosis of sarcopenia and obesity.
Sarcopenia diagnosis
Muscle mass
Clinical setting
Extremity circumferences (thigh, arm) Anthropometry Total or partial body potassium per fat-free soft tissue MAMA (middle-arm muscle area)
Research setting
DEXA (dual-energy X-ray absorptiometry) Thigh US (ultrasound) BIA (bioelectrical impedance analysis) Magnetic resonance imaging (MRI)
Muscle strength
Clinical setting
Handgrip strength Knee flexion/extension 1 maximum repetition (1RM) 10 maximum repetitions (10RM) Peak expiratory flow (specific to respiratory)
Research setting
Isokinetic evaluation Dynamometer
Physical performance
Clinical setting
Gait speed Short physical performance battery 6-MWT (6-minute walk test) 2-MST (2-minute step test) Chair stands Timed get-up-and-go test Stair climb power test
Research setting
CPET (cardiopulmonary exercise testing)
Obesity diagnosis
Clinical setting
Body mass index (BMI) (≥30 kg/m2)
Fat mass (FM) % (>25% for men and >35% for women)
Waist circumference (≥88 cm for women and 102 cm for men)
