The effect of eccentric phase duration on maximal strength, muscle hypertrophy and countermovement jump height: A systematic review and meta-analysis
Overview
Paper Summary
This meta-analysis investigated the effects of eccentric phase duration on strength, muscle growth, and jump height. Shorter eccentric phases led to greater improvements in jump height, while longer phases may be better for strength gains in trained individuals or when volume-load is matched. Results for muscle growth were inconclusive, highlighting the need for further research.
Explain Like I'm Five
Shorter eccentric phases (muscle lengthening during exercise) are better for improving jump height, while longer phases might be better for strength, especially in trained individuals. More research is needed on hypertrophy (muscle growth).

Identified Limitations
Rating Explanation
This meta-analysis provides valuable insights into the effects of eccentric phase duration on various training outcomes. It uses a robust methodology with appropriate statistical analyses. However, the small sample sizes and some limitations in the included studies warrant a rating of 4, rather than 5.
