Recently, the concept of eccentric overload training has been gaining a lot of social media coverage and popularity.  This type of training has been around for a while despite its uncommon use in an S&C coach’s toolbox.

Abstract

 

Objectives

The purpose of this meta-analysis was to examine the effect of flywheel (FW) resistance training with Eccentric Overload (FW-EOT) on muscle size and functional capacities (i.e. strength and power) in athletes and healthy subjects, and to compare FW-induced adaptations with those triggered by traditional resistance exercise interventions.

 

Design

A systematic review and meta-analysis of randomised controlled trials.

 

Methods

A search of electronic databases [PubMed, MEDLINE (SportDiscus), Web of Science, Scopus and PEDro] was conducted to identify all publications employing FW-EOT up to April 30, 2016. Outcomes were analyzed as continuous outcomes using a random effects model to calculate a standardized mean difference (SMD) and 95% CI. A total of 9 studies with 276 subjects and 92 effect sizes met the inclusion criteria and were included in the statistical analyses.

 

Results

The overall pooled estimate from the main effects analysis was 0.63 (95% CI 0.49–0.76) with a significant (p
