er wordt onderzoek gedaan naar preventie van spierblessures hamstring/calf strain hamstring/kuit rupture
Conditions
Interventions
Validation study: The aim of the in vivo validation study is to evaluate the
validity of ultrasound and DT-MRI. DT-MRI will be compared with ultrasound for
measuring PA, FL, MT, MV and CSA in order

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary outcome measures are DT-MRI and ultrasound derived muscle characteristics: pennation angle (PA: the angle of the fascicles relative to the tendon; degrees) and fascicle length (FL: the length of the muscle fascicles running between the aponeuroses/tendons; mm). | — |
Secondary
| Measure | Time frame |
|---|---|
| Hamstring strength; Calf strength; Playing hours per participant; MR outcome parameters to assess muscle characteristics cross-sectional area (CSA; mm2); muscle thickness (MT; mm); muscle volume (MV; mm3); Injury rate (injury per 1000 playing hours) with injury type and location; Severity defined as time-loss injuries. Time-loss is defined as time (in days) absent from either training or matches. Patient reported Outcome score: Functional Assessment Scale for Acute Hamstring Injuries; EMG amplitude and activation patterns of the following muscles: Hamstrings, Gastrocnemius, Quadriceps, Adductor, Gluteal and trunk muscles, Spatiotemporal EMG distribution within the hamstring muscle. Joint kinematics of the: Ankle, Knee, Hip, Trunk | — |
