The effect of stretch–shortening magnitude and muscle–tendon unit length on performance enhancement in a stretch–shortening cycle [PDF]

open access: yesScientific Reports, 2021
Stretch-induced residual force enhancement (rFE) is associated with increased performance in a stretch–shortening cycle (SSC). Although the influence of different range of motions and muscle–tendon unit lengths has been investigated in pure stretch-hold ...

Factors of force potentiation induced by stretch-shortening cycle in plantarflexors. [PDF]

open access: yesPLoS ONE, 2015
Muscle force is potentiated by countermovement; this phenomenon is called stretch-shortening cycle (SSC) effect. In this study, we examined the factors strongly related to SSC effect in vivo, focusing on tendon elongation, preactivation, and residual ...

Modulation of stretch activation influences the stretch‐shortening cycle effect in in vivo human knee extensors [PDF]

open access: yesPhysiological Reports
This study investigated the effects of progressively increasing voluntary activation during the stretch phase on force and work production in the stretch‐shortening cycle (SSC) of human knee extensors.

Energy Cost of Force Production After a Stretch-Shortening Cycle in Skinned Muscle Fibers: Does Muscle Efficiency Increase? [PDF]

open access: yesFrontiers in Physiology, 2021
Muscle force is enhanced during shortening when shortening is preceded by an active stretch. This phenomenon is known as the stretch-shortening cycle (SSC) effect.

Pre-activation affects the effect of stretch-shortening cycle by modulating fascicle behavior [PDF]

open access: yesBiology Open, 2019
The torque attained during active shortening is enhanced after an active stretch (stretch-shortening cycle, SSC). This study examined the influence of pre-activation on fascicle behavior and the SSC effect.

Evidence for Muscle Cell-Based Mechanisms of Enhanced Performance in Stretch-Shortening Cycle in Skeletal Muscle [PDF]

open access: yesFrontiers in Physiology, 2021
Force attained during concentric contraction (active shortening) is transiently enhanced following eccentric contraction (active stretch) in skeletal muscle. This phenomenon is called stretch-shortening cycle (SSC) effect.

Effect of Preactivation on Torque Enhancement by the Stretch-Shortening Cycle in Knee Extensors. [PDF]

open access: yesPLoS ONE, 2016
The stretch-shortening cycle is one of the most interesting topics in the field of sport sciences, because the performance of human movement is enhanced by the stretch-shortening cycle (eccentric contraction).

Force depression following a stretch-shortening cycle is independent of stretch peak force and work performed during shortening [PDF]

open access: yesScientific Reports, 2018
The steady-state isometric force following active muscle shortening or lengthening is smaller (force depression; FD) or greater (residual force enhancement; RFE) than a purely isometric contraction at the corresponding length. The mechanisms behind these

Medial Gastrocnemius Muscle Architecture Is Altered After Exhaustive Stretch-Shortening Cycle Exercise [PDF]

open access: yesFrontiers in Physiology, 2019
Muscle architecture is an important component of muscle function, and recent studies have shown changes in muscle architecture with fatigue. The stretch-shortening cycle is a natural way to study human locomotion, but little is known about how muscle ...

Maximal eccentric–concentric strength determines stretch-shortening cycle leg power across biological sexes [PDF]

open access: yesScientific Reports
The ratio of eccentric-to-concentric force output (E/C ratio) is higher in female compared to male individuals, however, the functional implications for stretch-shortening cycle (SSC) leg power output remains unknown. Thus, in the present study, male and
