Description
Summary:Mafra O, Senna GW, Leal SMO, Conceicao MCS, Meza EA, Guimaraes AC, Maia BLC, Dantas EHM. Hydroxyproline Concentration, Electrogoniometry, EMG Responses, and Correlations after Different Stretching Methods, JEPonline 2017;20 (6):55-65. The purpose of this study was to analyze the hydroxyproline level (HP), electromyography signal (EMG), and range of motion in sedentary young subjects submitted to static stretching and proprioceptive neuromuscular facilitation (PNF). The sample was randomly divided into: (a) PNF; (b) static stretching; and (c) control group. This study used the Nordim method (HP); biceps femoris electromyography and electrogoniometry (hip angle) value to assess the data. For HP results, FG (P=0.0001) and SG (P=0.002) showed significant increase compared to the pre-test. At 24 hrs post, the FG (P=0.018) and SG (P=0.005) showed significant increase in comparison to CG. For EMG results, FG (P=0.0001) and SG (P=0.033) demonstrated significantly lower muscle activity in the post-test. Inter-variable comparison showed a significant inverse correlation between EMG and HP (r = -0.624, P=0.013) and between EMG and goniometry (r = -0.562, P=0.029). The findings indicate that both stretching methods promote an increase in hydroxyproline levels and reduced electric activity in the biceps femoris muscle.
