The aim of this study was to investigate the effects of a 12-week flexibility training at different intensities on range of motion (ROM), horizontal shoulder flexion and extension (HSF and HSE) and lumber spine flexion (LSF) in military personnel. The sample consisted of 90 students (17.02 ± 1.24 years) randomly allocated into three groups of 30 participants each: stretching (SG) proprioceptive neuromuscular facilitation (PNFG) and control (CG). Joint range was measured by goniometry using the LABIFIE protocol and the Lafayette Goniometer Set (360º)– USA as measuring instrument. The scale of perceived exertion in flexibility – PERFLEX (0 – 110) was applied to control intensity in the SG (31- 60) for 5 seconds and the PNFG (61 and 80) for 8 seconds for each phase. Three series, five seconds apart, were conducted. Comparative analysis of joint range levels determined by analysis of variance (one-way ANOVA) and Tukey’s post-hoc test revealed differences only in PNFG: HSF (∆%=4.6; p=0.001); HSE (%∆=8.6; p=0.002); LSF (∆%=56.1; p=0.001). It was concluded that PNF training achieved higher ROM when compared to stretching.
