Fatigue, Landing Biomechanics
Conditions
Brief summary
In this prospective study, male jump-landing athletes (volleyball and basketball) will be screened pre-season and followed for one consecutive season. Pre-season screening consists of 3D biomechanical analysis of standardized (such as drop vertical jump) and sports-specific jumps (such as stop-jump) before and after a high-intensity, intermittent exercise protocol and clinical field tests (such as force measurements).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Jump-landing biomechanics | 1 year | Full-body (trunk, pelvis, hip, knee, ankle) jump-landing biomechanics (3D joint angles and moments) during drop vertical jumps, block jumps and spike jumps |
| Jump-landing biomechanics after fatigue | 1 year | Full-body (trunk, pelvis, hip, knee, ankle) jump-landing biomechanics (3D joint angles and moments) during spike jumps during and after a fatigue protocol |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Clinical tests - foot posture | 1 year | Navicular height and position of the calcaneal bone |
| Clinical tests - force | 1 year | Force measurements of the quadriceps, hamstrings and gluteal muscles by means of hand-held dynamometry |
| Clinical tests - endurance | 1 year | Intermittent yo-yo test (level 1) |
| Clinical tests - force endurance | 1 year | Prone bridge until fatigue |
| Clinical tests - mobility | 1 year | Flexibility of the quadriceps and hamstrings muscles, and ankle dorsiflexion angle during dynamic weight-bearing lunge |
