Abstract

ROSARIO, José Luís Pimentel do et al. Global posture reeducation and static muscle stretching on improving flexibility, muscle strength, and range of motion: a comparative study. Fisioter. Pesqui. [online]. 2008, vol.15, n.1, pp.12-18. ISSN 1809-2950.  http://dx.doi.org/10.1590/S1809-29502008000100003.

Stretching exercises are prescribed to increase flexibility and range of motion (ROM). Two current stretching methods are the global posture reeducation (GPR), where muscle chains are stretched, and segmentary exercises, where a single muscle or muscle group is stretched. The aim of this study was to compare these two techniques, assessing their effects on improving flexibility, ROM and muscle strength. Thirty women were randomly distributed into three groups (n=10 each): global group performed stretching following GPR method; segment group performed segment stretching exercises; and control group did no exercise. Before and after treatment, in all groups, knee extension ROM, flexibility by means of the fingertip-to-floor test, and isometric muscular strength at 45° and 90° knee flexion were measured. Each treated group performed eight stretching 30-minute sessions for four weeks, twice a week. Data were statistically analysed and the significance level set at p<0.05. Global and segment group results were similar and better than control group's concerning ROM, flexibility and muscle strength at 45° and 90° knee flexion (p<0.05). When assessing improvement inter-sessions, both groups had better ROM improvement at the first sessions, decreasing along the others. Both global and segmentary stretching techniques were hence found effective in improving flexibility, ROM and leg muscle strength.
