Eligibility
Inclusion criteria
Inclusion criteria: 1. Healthy subjects: no neuromuscular disorders, no joint disorders, no metal implants, no pacemaker; 2. Age: 21-30 years, to exclude age-effects; 3. Eight men, eight women; 4. Different physical activity levels (five sportsmen, six semi-sportsmen, five non-sportsmen); 5. Volunteers willing to participate; 6. Fully competent.
Exclusion criteria
Exclusion criteria: 1. Neuromuscular disorders. Neuromuscular disorders can affect the conduction speed; 2. Known joint disorders in the hip, leg and/or knee. Theses disorders can cause confounding in the measurements; 3. Metal implants in hip, leg or knee. Metal implants can cause a disturbance in the electrical field, causing overheating and burn of the tissues surrounding the metal; 4. Cardial pacemaker or Internal Cardiac Defibrillator (ICD); 5. Lack of motivation to participate in this study.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. Quadriceps muscle endurance: Tlim (number of contractions until 20, 30 and 40% torque decline), Steady state (% peak torque), transition point of the force decline curve (s); 2. Biceps muscle endurance: Tlim (number of contractions until 20, 30 and 40% torque decline), Steady state (% peak torque), transition point of the force decline curve (s). | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Quadriceps muscle strength (Nm); 2. Biceps muscle strength (Nm); 3. Date of birth, gender, length, weight, BMI. | — |
