Biomechanical Analysis
What your body
needs to excel.
Athlete Profile assesses the specific biomechanical traits that predict elite performance in Rugby. These aren't generic fitness metrics - they're sport-specific physiological signatures.
Force Absorption Capacity
The physiology of contact tolerance
Rugby players absorb contact forces of 6–14x body weight during tackles at competitive level. Force absorption capacity is determined by eccentric muscle strength, bone mineral density, and subcutaneous tissue distribution. Our CMJ landing mechanics assessment captures your eccentric loading quality - the primary determinant of contact durability.
Relative Lean Mass Index
Body composition as sport suitability metric
Rugby's contact rules create body composition selection pressure unlike any other sport. Forwards benefit from high lean mass with moderate fat mass for contact cushioning; backs require sprint speed with low relative body fat. Your Athlete Profile body composition index predicts which positional group fits your natural morphology.
Eccentric Hamstring Strength
The sprint-contact injury triangle
Rugby combines maximal sprinting with sudden collision - the two highest-risk scenarios for hamstring muscle-tendon junction failure. Eccentric hamstring weakness during the late swing phase, combined with impact deceleration forces, is the primary mechanism of proximal hamstring avulsion in rugby players.
Cervical & Thoracic Spine Load Tolerance
Scrum and ruck structural readiness
Scrummaging generates axial compressive forces of 1,500–2,000N on the cervical spine. Cervical spine strength, thoracic kyphosis angle, and shoulder girdle mass determine structural readiness for high-load scrummaging - a critical safety assessment for youth rugby athletes (U14–U18) considering forward positions.
What Athlete Profile Measures
Your Rugby
assessment report.
Peak Power Output (W/kg)
Elite forwards achieve 35–45 W/kg; elite backs achieve 40–55 W/kg with lower absolute mass but higher relative power. Your power-to-mass ratio predicts natural positional affinity.
Positional Somatotype Profile
Props trend endomorphic-mesomorphic (high mass, high strength); backs trend mesomorphic-ectomorphic (high power-to-weight, high sprint speed). Morphological profile predicts positional role.
Anaerobic Capacity & Repeatability
Your sprint deceleration index and CMJ fatigue drop-off predict anaerobic capacity repeatability - how many maximal efforts you can sustain across an 80-minute match.
Bone Mineral Density Proxy
Your anthropometric index, sport history, and training load pattern generate an estimated bone mineral density risk profile - critical for youth athletes in collision sports.
