All subjects will receive the three stretching techniques on dominant leg. Interventions will be performed in three different days and only one of the three stretching exercises will be performed in each session. The rest period between sessions will be one week. Stretching exercises will be perform in a random order. A random-number generator will be used for randomization

The stretched lower limb was on a mobile support and the contralateral limb was stabilized with a belt on the bench. For the SLR, the knee was kept in full extension and then, hip flexion was performed until a marked resistance. All stretching modalities were applied until a marked resistance was felt by the physical therapist (end-feel) or until the point of maximal tolerance referred by subjects.The stretch lasted 30 seconds followed by 15 seconds rest period and the procedure was repeated 5 times. Each stretching was applied for 5 minutes

subjects will perform a single-leg sit-and-reach on a bench. The untested leg will be placed on the floor with knee at approximately 90º. A measuring tape will be placed on the bench. Subjects aligned the sole of the foot of the tested leg with the 50-cm mark on the measuring tape. Thereafter, subjects will be asked to reach forward as far as possible while maintaining the knees, arms, and fingers fully extended, and keep in the two hands on tip of each other and palms down

Passive ankle dorsiflexion was performed as distal sensation manoeuvre at the final position of all stretching modalities. Subjects were asked to indicate if the sensation during the stretching was modified during the ankle dorsiflexion (neural response) or was the same (musculoskeletal response)

The intensity of the force applied during each stretching modality was measured by a manual dynamometer (MicroFET2, Hoggan Scientific, Salt Lake City, Utah). The dynamometer was applied on the distal leg, proximal to the ankle joint. The physiotherapist performed the stretching until a marked resistance was felt and then, the force was registered.

After the stretching application, all subjects were asked about their perceived sensation. They were asked about the intensity of the tension sensation during the technique. A numeric scale, ranging from 0 ("no tension") to 10 ("worst tension imaginable") was used to indicate the intensity of tension sensation during the stretching technique.
