Developing Core Strength In Classical Ballet Dancers Through Kettlebell Training

A Methodological Experiment

Abstract

A functional strength training tool, the kettlebell, has been used by classical ballet
students at the Hungarian Dance University in skill development classes since
2021. In addition to the considerable positive subjective feedback on the effects
of kettlebell training, it is important to investigate the results of such training in
an objective way. The focus of the program that the participants
(n=10) took part in was on developing the muscular strength of the trunk, which
provides support and stability for the dancer during certain movements,
specifically when lifting a partner. In order to quantify the development of core
muscle strength, the directional force of the extensor muscles in the back and
lumbar spine were measured using a hand-held muscle strength meter. The
program covered six weeks, with measurements taken at the beginning and the
end. The methodological experiment demonstrated that targeted functional training
produces measurable positive changes even at low hourly rates (+10.16%). Regular
use of the kettlebell helps dancers to prepare for and execute lifts with
precision, as well as to better execute a number of other technical elements.
