Reduced Maximal Force Production on Unstable Surfaces: Stable vs Unstable Conditions

Anderson KG, Behm DG

Year2004

Sample sizen=10

JournalJournal of Strength and Conditioning Research

AuthorsAnderson KG, Behm DG

Evidence is still limited and needs further study

Summary

A study of 10 men comparing stable and unstable conditions in the chest press. Isometric maximal force fell sharply under instability while EMG activity did not differ, interpreted as instability diverting muscular resources to joint stabilisation at the expense of force output.

Key point

1
The study tested 10 men in the chest press
2
Isometric maximal force under the unstable condition was 59.6% lower than under the stable condition
3
Meanwhile EMG activity did not differ significantly between conditions
4
Instability was interpreted as diverting muscular resources to joint stabilisation at the expense of force output

Are Cushioned Shoes Bad for Lifting? Myth vs Research
'Squatting or deadlifting in soft, cushioned running shoes lets your power leak away' and 'flat soles or barefoot are the only right choice for lifting' — you hear this a lot in gyms. So how much does shoe cushioning actually affect your lifting results or safety? We'll look at the biomechanics research, but up front: this area is very thinly studied. We'll honestly separate what we know from what we don't.
