Long-Term Effects of a 6-Week Power-Based Resistance Training and Fast Walking Interval Training Program on Physical Function, Muscle Power, Disability, and Frailty in Pre-Frail and Frail Older Adults.

Introduction: Concurrent training has been shown to be a beneficial approach to improve overall health status in older adults. However, little is known about the adaptations of this type of training in the long term (i.e.

Comparison of available equations to estimate sit-to-stand muscle power and their association with gait speed and frailty in older people: Practical applications for the 5-rep sit-to-stand test.

Objectives: This study aimed i) to compare relative sit-to-stand power (STS) values yielded by the different equations reported in the literature; ii) to examine the associations between STS, derived from the equations, and age, sex, frailty and habitual gait speed (HGS); and iii) to compare the ability of the different STS equations to detect frailty and low HGS in older adults.

Methods: 1568 participants (>65 years) were included. STS was calculated according to four validated equations.
