Contribution of Stretch-Induced Force Enhancement to Increased Performance in Maximal Voluntary and Submaximal Artificially Activated Stretch-Shortening Muscle Action

Frontiers in Physiology, 2020
In everyday muscle action or exercises, a stretch-shortening cycle (SSC) is performed under different levels of intensity. Thereby, compared to a pure shortening contraction, the shortening phase in a SSC shows increased force, work, and power.

Investigating the Correlation Between Agility and Jump Performance Indices in Indian Contact Sports Persons: An Observational Study

Journal of Modern Rehabilitation, 2023
Introduction: The use of the jump as a plyometric exercise is a way to improve jump performance. Additionally, as it requires abrupt stopping, starting, and changing directions, it might enhance agility.

The role of ssc cycle in hockey off-ice training

Slovak Journal of Sport Science, 2022
The Stretch and shortening cycle (SSC) is one of the most common used mechanism in a human body. The objective of this study was to determine a level of slow and fast stretch-shortening cycle utilization in elite ice hockey players and prescribe some ...

Acute Effects of Different Plyometric and Strength Exercises on Balance Performance in Youth Weightlifters

Frontiers in Physiology, 2021
Background: High-intensity muscle actions have the potential to temporarily improve the performance which has been denoted as postactivation performance enhancement.Objectives: This study determined the acute effects of different stretch-shortening (fast

The Influence of Growth and Maturation on Stretch-Shortening Cycle Function in Youth [PDF]

Sports Medicine, 2017
Hopping, skipping, jumping and sprinting are common tasks in both active play and competitive sports. These movements utilise the stretch-shortening cycle (SSC), which is considered a naturally occurring muscle action for most forms of human locomotion.

Effect of Plyometric Training on Jumping, Sprinting and Change of Direction Speed in Child Female Athletes

Sports, 2019
Background: This study examined the effects of 8 weeks of plyometric training on jumping, sprinting, and change of direction (COD) performance. Methods: Fifty female 7−9-year-old gymnasts were randomly assigned to a plyometric training group (PG; n

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level

Aging and Cancer, EarlyView.
This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

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

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.
