Primaire uitkomstmaten
fascicle lengths as determined by B-mode ultrasound
Achtergrond van het onderzoek
Objective: The aim of this study is to determine muscle fascicle behavior during three hamstring exercises. These exercises will also be compared on their required hamstring muscle force and muscle activity.
Study design: Cross-sectional study
Study population: Male athletes between 18-30 years old that participate in running-based sports.
Main study parameters/endpoints: 1) Muscle force of the biceps femoris long head, short head, semitendinosus and semimembranosus, 2) surface electromyographic activity of the biceps femoris long head and medial hamstrings, 3) fascicle length changes of the biceps femoris long head.
Doel van het onderzoek
Fascicle length changes will be larger in the Nordic curl and single-leg deadlift compared to the Roman chair
Onderzoeksopzet
One time point (cross-sectional study) during which muscle activity is determined by surface electrodes, muscle forces are determined by static optimization and inverse dynamics from external force measurements and 3D motion analysis and fascicle lengths are determined from b-mode ultrasound.

Algemeen / deelnemers
Wetenschappers
Belangrijkste voorwaarden om deel te mogen nemen (Inclusiecriteria)
- Between 18-30 years old
- Participating in a sport that involves a considerable amount of high-speed running (i.e., > ~18 km/h) for at least three times a week. Sports that meet this criterion are football (soccer) rugby, hockey, running (when performing high-intensity interval training for at least three times a week);
- Male
- >1.65 m of height because long individuals are needed for a simultaneous measurement of ultrasound and surface electromyographic activity.
Belangrijkste redenen om niet deel te kunnen nemen (Exclusiecriteria)
Severe visual or hearing impairment since this makes explanation of the correct exercise technique more difficult;
- History of a previous injury to the leg or back within the previous 24 months;
