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

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

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

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

The Importance of Impact Loading and the Stretch Shortening Cycle for Spaceflight Countermeasures [PDF]
Frontiers in Physiology, 2019 Pronounced muscle and bone losses indicate that the musculoskeletal system suffers substantially from prolonged microgravity. A likely reason for these detrimental adaptations in the lower extremity is the lack of impact loading and the difficulty to ...

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

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