Brief Summary

This study aims to evaluate and compare muscle activation patterns during single-leg bridge exercise variations performed on mat and reformer Pilates equipment using surface electromyography (sEMG). The effects of different reformer spring resistances on neuromuscular activation will also be investigated.

Conditions

Muscle Activation; Pilates Method; EMG

Keywords

Pilates, Reformer, Electromyography, Muscle Activation, Single-Leg Bridge Exercise.

Outcome Measures

Primary Outcomes (1)

• Surface Electromyographic (sEMG) Activity of Trunk and Lower Extremity Muscles

  Surface electromyographic activity (%MVIC) of the erector spinae, gluteus maximus, biceps femoris, semimembranosus, upper and lower rectus abdominis, medial gastrocnemius, and lateral gastrocnemius was measured during single-leg bridge and single-leg bridge with heel raise exercises performed on a mat and on a reformer under five different spring resistance conditions.

  Measured during a single study visit Day 1 while participants performed the exercise conditions.
