Genetic Contribution to Vertical Jump Performance
I cannot provide a definitive percentage for the genetic contribution to vertical jump ability based on the evidence provided, as none of the studies directly quantify heritability or genetic factors for this trait.
What the Evidence Actually Shows
The provided studies focus entirely on performance characteristics, training methods, and anthropometric measurements in basketball players and other athletes, but do not address genetic heritability 1.
Limited Genetic Discussion
Only one brief mention exists regarding genetics in sport performance generally 1:
- The evidence acknowledges "there is a genetic component to sporting performance" and questions "which genetic profiles make the greatest contribution" 1
- However, this statement is made in the context of talent identification across all sports, not specifically for vertical jump ability 1
- No quantitative heritability estimates are provided 1
What Influences Vertical Jump (Non-Genetic Factors Identified)
The evidence demonstrates multiple trainable and anthropometric factors that influence vertical jump performance:
Anthropometric Variables 2, 3:
- Body mass and relative body fat percentage show strong negative correlations with jump height (r = -0.76 for body fat) 3
- Upper arm length, thigh length, and limb dimensions predict jump performance 2, 3
- Static Q-angle shows negative correlation (r = -0.55) with jump displacement 3
Kinetic Variables 3:
- Peak and average concentric power (r = 0.74-0.81) 3
- Peak and average vertical ground reaction force (r = 0.46-0.67) 3
- Vertical impulse (r = 0.32-0.54) 3
Sport-Specific Training Effects 4:
- Athletes from different sports show distinct jumping strategies reflecting their training demands 4
- Volleyball players demonstrate temporal-prevailing profiles, while high jumpers show force-dominant profiles 4
Clinical Bottom Line
The genetic contribution to vertical jump ability remains unquantified in the available evidence. While genetics clearly play a role in athletic performance generally 1, the specific heritability percentage for vertical jump cannot be determined from studies focused on performance testing, anthropometry, and training adaptations [1-3]. The substantial influence of modifiable factors—including body composition, training status, and technique—suggests meaningful performance improvements are achievable regardless of genetic baseline 4, 3.
