Muscle contraction type-specific association of acceleration and deceleration performance with rates of force development.

ABSTRACT:

Background

Many sports require rapid acceleration and deceleration, particularly when changing direction. These movements require a large impulse, highlighting the importance of rates of force development (RFDs). However, the relationships between acceleration and deceleration performance and concentric and eccentric RFDs have remained uncertain. This study evaluated the correlation between RFDs in different muscle contraction types and acceleration and deceleration performances.

Methods

This study included 28 healthy subjects (13 males and 15 females; age: 21 ± 2 years; height: 1.66 ± 0.09 m; body mass: 65 ± 10 kg). Concentric, eccentric, and isometric RFDs were evaluated by having the subjects perform squat jumps, countermovement jumps, and isometric squats, respectively.
