Abstract

BACKGROUND

The co-contraction of the core muscles has been reported as the key mechanism towards spinal stability. Classic Pilates exercises aimed at these muscles are known to improve the stability and strength of the trunk without damaging the deep structures of the spine.

OBJECTIVE

To evaluate the co-contraction of the mobilizing (rectus abdominis; longissimus) and stabilizing (multifidus; internal oblique) trunk muscles during Pilates exercises - going up front, mountain climber, and swan.

METHODS

Sixteen women, all Pilates practitioners, participated in the study. The stabilizing and mobilizing muscles of the trunk (right side) were submitted to electromyography to calculate the percentage of co-contraction during the exercises. One-way repeated measures analysis of variance (ANOVA) was used to verify the difference in %COCON between stabilizers and mobilizers among the three exercises. The post-hoc Bonferroni test (P< 0.01) was applied when necessary. The paired t-test (P< 0.01) was used to verify the difference in %COCON between stabilizers and mobilizers separately for each exercise.

RESULTS

The co-contraction values of the stabilizers were higher than those of the mobilizers for all exercises. The going up front (stabilizers) and the swan (mobilizers) exercises showed the highest %COCON values.

CONCLUSIONS

The Pilates method is effective for either rehabilitating pathologies or training the trunk muscles in healthy individuals and athletes.

摘要

背景

核心肌群的协同收缩被认为是脊柱稳定的关键机制。旨在针对这些肌肉的经典普拉提练习被认为可以在不损害脊柱深部结构的情况下提高躯干的稳定性和力量。

目的

评估普拉提练习（前屈、登山式和天鹅式）中活动（腹直肌；最长肌）和稳定（多裂肌；内斜肌）躯干肌肉的协同收缩。

方法

16 名女性均为普拉提练习者参加了这项研究。对躯干（右侧）的稳定肌和活动肌进行肌电图测量，以计算运动过程中的协同收缩百分比。使用单向重复测量方差分析（ANOVA）来验证三种运动方式中稳定肌和活动肌之间的%COCON 差异。必要时应用事后 Bonferroni 检验（P<0.01）。使用配对 t 检验（P<0.01）分别验证了三种运动方式中稳定肌和活动肌之间的%COCON 差异。
