Clinical Trial Summary
Investigation of power and speed in relation to the increasing instability in a group of
untrained athletes and a group of expert athletes. In this way, the effectiveness of unstable
training for different types of athletes can be tested.
Our hypothesis is that as instability increases there is a gradual decrease in power and
speed of execution, but not too relevant in the expert group.
Description:
Introduction
Strength training using devices that induce varying degrees of instability is widely
practiced in numerous contexts and has been credited with benefits in prevention,
rehabilitation and general health. Several studies have found a progressive decrease in power
as the degree of instability increases. However, it is not known how mildly unstable
situations are affected, nor are the differences between trained and untrained subjects.
The purpose of the present study was to compare the effect of different degrees of
instability on power and speed of execution in a push-up or arm-bottoms exercise, in trained
and untrained subjects.
Method
Maximum power (MP) and mean power (BP), and maximum speed (MV) and mean propulsive speed (VA)
of push-up were analyzed in 44 subjects, 24 untrained (176.38±5.35 cm, 76.38±6.85 kg, 2.5±1.5
months experience) and 20 trained (178.45±5.91 cm, 83.4±21.56 kg, 15.5±5.3 months
experience), under six conditions of increasing instability: 1) stable, 2) device in
suspension: rings, 3) monopodal, 4) device in suspension: TRX®, 5) with hands-on Bosu® and 6)
with hands-on TRX® and feet on Bosu®.
