This study examined the relationship between sit-to-stand (STS) power and physical function in adults with severe obesity. Thirty-eight (age: 44 ± 12 years; body mass index [BMI]: 45.2 7.8 kg/m2) completed evaluations of STS power, strength functional performance. was measured a wearable inertial sensor, assessed isometric mid-thigh pull, timed up-and-go (TUG), six-minute walk test (6MWT) 30-s chair STS. Power (normalised to mass) entered regression models addition age, gender, BMI activity (daily step count). displayed large univariate associations TUG (r = 0.50) 0.67), moderate association 6MWT 0.49). Forward stepwise revealed that independently contributed (β −0.40, p 0.010), 0.67, < 0.001) performance 0.27, 0.007). also appeared be superior determinant compared strength. generated via transfer largely underpins ability perform tasks obesity, although intervention studies are required investigate potentially causal relationship.
