Brief Summary

The aim of this study was to investigate the effects of different concentric and eccentric muscle fatigue protocols on the knee joint position sense of healthy individuals.

Conditions

Healthy

Keywords

Muscle Fatigue; Knee; Joint Position Sense; Proprioception

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 (Before) to Immediately after interventions or control (After)

• Relative angular error

  The arithmetic difference between the target range and the range achieved

  Change from Baseline (Before) to Immediately after interventions or control (After)

• Variable angular error

  The standard deviation of the 3 repositionings

  Change from Baseline (Before) to Immediately after interventions or control (After)

Study Arms (5)

Control Condition

NO INTERVENTION

5-minute rest period.

Quadriceps_Concentric

ACTIVE COMPARATOR

40 consecutive maximal concentric contractions of quadriceps at 30º/s

Other: Muscle fatigue Protocol

Quadriceps_Eccentric

ACTIVE COMPARATOR

40 consecutive maximal eccentric contractions of quadriceps at 30°/s

Other: Muscle fatigue Protocol

Hamstrings_Concentric

ACTIVE COMPARATOR

30 consecutive maximal concentric contractions of hamstrings at 30º/s

Other: Muscle fatigue Protocol

Hamstrings_Eccentric

ACTIVE COMPARATOR

30 consecutive maximal eccentric contractions of the hamstrings at 30º/s

Other: Muscle fatigue Protocol

Interventions

Muscle fatigue Protocol OTHER

Four experimental conditions consisting of different local muscle fatigue protocols performed in the isokinetic dynamometer in random order, with at least one week of interval between them.

Eligibility Criteria

• Age: 18 Years - 30 Years
• Sex: male
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64)

You may qualify if:

• males aged between 18 and 30 years;
• without current or previous knee pathology or surgery;
