WHAT THE AI SAW
Build type
ECTOMORPHIC
- •Positive ape index (+3 cm) for height
- •Very low body mass and lean BMI
- •Shoulder-to-hip ratio ~1.26 with narrow hips
- •Leg-to-torso ratio ~1.33 (longer legs)
- •Small-to-moderate hands/feet aiding precision on small holds/footholds
THE AI'S SPORT RANKINGS
Sport climbing (lead)
Exceptional fit: very high strength-to-weight, positive ape index for reach, precise small hands/feet for technical footholds and crimps, and economy over long routes. Lead emphasizes endurance and technique where low mass and reach confer clear advantages.
Road cycling – climbing specialist
Low body mass and narrow hips reduce power-to-weight and aerodynamic penalties on climbs. Leg-dominant proportions support efficient torque; smaller frame excels on steep gradients and long ascents.
10,000 m running
Lean build with narrow pelvis favors running economy and heat dissipation. Leg-dominant proportions aid stride efficiency; low mass reduces energy cost per step—ideal for sustained aerobic events.
Boxing (flyweight/bantamweight)
Within lighter divisions, the positive ape index gives modest reach advantage; low mass benefits speed and work rate. Moderate shoulder breadth limits raw punching power, but reach/speed/agility remain assets.
Badminton (singles)
Light, agile build with slight reach advantage aids court coverage, recovery steps, and overhead reach. Emphasis on acceleration, endurance, and precision aligns with the profile; height is not a strict prerequisite.
BIOMECHANICAL READ
- 1High strength-to-weight potential from low mass and ectomorphic build—key for vertical movement and endurance.
- 2Positive ape index enhances reach for clipping/holds (climbing), striking range (boxing), and defensive coverage (racket sports).
- 3Narrow hips with decent shoulder-to-hip ratio aid running economy, agility, and change of direction.
- 4Leg-dominant proportions support efficient stride mechanics and good cycling leverage while keeping frontal area low.
- 5Smaller hands/feet improve precision on small grips and footholds (valuable in technical climbing).
LESS ADVANTAGEOUS IN
- •Rowing (height/leverage favored)
- •Swimming sprints (height, large wingspan, and broad shoulders favored)
- •Throwing events (shot put/discus/javelin) and strongman/powerlifting (require mass and lever advantages)
- •Basketball/volleyball (height-reliant)
- •American football/rugby forward positions (mass/impact tolerance)
- •Kayak/Canoe sprint (upper-body power and mass)
- •Track power sprints (100–200 m) where peak power and musculature dominate
METHODOLOGY
The AI analysis above was generated from the nine measurements listed — nothing else. The model never saw Eliud Kipchoge's name, photo, or sport; it received the same anonymous input as any visitor who uses the tool. The verdict compares its blind rankings with reality.
Measurements marked Est. are not publicly documented and were estimated from published data using the noted anthropometric ratios.
