Outcome Measures

Primary Outcomes (3)

  • Absolute angular error

    The absolute value of the difference between the target range and the achieved range

    Change from Baseline (Pre) to Immediately after interventions or control (Post)

  • Relative angular error

    The arithmetic difference between the target range and the range achieved

    Change from Baseline (Pre) to Immediately after interventions or control (Post)

  • Variable angular error

    The standard deviation of the 3 repositionings

    Change from Baseline (Pre) to Immediately after interventions or control (Post)

Study Arms (3)

Control Condition

NO INTERVENTION

5-minute rest

Static Stretching of 30 seconds

ACTIVE COMPARATOR

Static stretching of the quadriceps and hamstrings for 30 seconds

Other: Static Stretching

Static Stretching of 90 seconds

ACTIVE COMPARATOR

Static stretching of the quadriceps and hamstrings for 90 seconds

Other: Static Stretching

Interventions

Static stretching of the quadriceps and hamstrings which was performed in the dominant limb, and held in a position where the participants referred discomfort: * Quadriceps - participants were in the standing position, with one hand holding the back of a chair to maintain the balance, and were instructed to pull the ankle of the lower limb to be stretched, pressing the heel towards the buttocks and, at the same time, extending the thigh; * Hamstrings - participants were also in the standing position, with the heel resting on a chair. They were then instructed to lean the body forward keeping the spine erect and the pelvis in anteversion, to obtain a stretch over the knee and hip.
