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< 0.001) Z overall effect of 9.17. No significant heterogeneity (p value = 0.78) was found. The meta-analysis showed significant differences between FW-EOT vs.
conventional resistance training in concentric and eccentric strength, muscle power,
muscle hypertrophy, vertical jump height and running speed, favoring FW-EOT.
Conclusions
This meta-analysis provides evidence supporting the superiority of FW-EOT, compared
with traditional weight-stack exercise, to promote skeletal muscle adaptations in
terms of strength, power and size in healthy subjects and athletes.
