Abstract

OLIVEIRA, Laís Campos de et al. Effects of the pilates method in isokinetic torque of knee extensors and flexors: pilot study. Rev Bras Med Esporte [online]. 2015, vol.21, n.1, pp.49-52. ISSN 1517-8692.  http://dx.doi.org/10.1590/1517-86922015210102095.

INTRODUCTION:

despite the popularity of Pilates as a form of exercise, studies with the technique still have not explored their effects on isokinetic torque of the extensor and flexor muscles of the knee.

OBJECTIVES:

check the effects of the Pilates method on isokinetic torque of the knee extensors and flexors in young women.

METHODS:

10 volunteers underwent isokinetic evaluation (60°/s and 300°/s) of the knee extensors and flexors of the dominant leg, pre-and post-intervention with the Pilates method, considering the peak torque (PT) and total work (TW). Eight interventions were conducted over four weeks, 28 consisting of stretching and strengthening exercises for the major muscle groups. Statistical analysis using the Student t or Wilcoxon for dependent samples was used (p<0.05).

RESULTS:

the results showed significant improvement for most of the observed variables in both knee extension (TW 60°/s - 8.98%, p = 0.0166, PT 300°/s - 11.80%, p = 0.0077, TW 300°/s - 19.68%, p = 0.0051) and in flexion (PT 60°/s - 11.44%, p = 0.0171; TW 60°/s - 11.55%, p = 0.0395; TW 300°/s - 12.86%, p = 0.0145), as an exception to two variables: one related to the movement of knee extension (PT 60°/s - 3.04 %, p = 0.4413) and the other to flexion (PT 300°/s - 2.30%, p = 0.3873).

CONCLUSION:

we found that eight sessions of Pilates, conducted over four weeks, provided significant improvement in isokinetic torque of the extensor and flexor muscles of the knee in young women, in relation to the PT and TT (60°/s and 300°/s) for most variables.
