The genetics question is one that every dunker encounters at some point — how much of vertical jump ability is genetic and how much is trainable? In episode 46 of Dunk Talk, Dylan Haugen and Donovan Hawkins take a deep dive into this topic, examining both the scientific evidence and their personal experiences to provide a nuanced perspective.
The Genetic Component
Dylan and Donovan acknowledge that genetics play a role in athletic performance. Factors like muscle fiber composition, limb proportions, tendon stiffness, and neuromuscular efficiency all have genetic components that influence an athlete’s baseline jumping ability and their ceiling for improvement. Some people are born with physical characteristics that give them a head start in explosive athletic activities.
However, both are quick to point out that genetics alone do not determine outcomes. The dunking community is full of athletes who have dramatically exceeded expectations based on their apparent genetic gifts, proving that training, technique, and determination can close significant gaps.
The Trainable Qualities
Donovan provides his perspective on which aspects of vertical jump performance are most responsive to training. Strength, rate of force development, technique, and reactive ability can all be significantly improved with dedicated training regardless of genetic starting point. He argues that most athletes have not come close to exhausting their trainable potential, making the genetics question somewhat premature for the vast majority of dunkers.
The Danger of the Genetics Excuse
One of the most impactful parts of the conversation addresses how the genetics narrative can become a self-limiting belief. Athletes who convince themselves that their genetics prevent them from achieving certain goals often stop putting in the effort required to reach their actual potential. Donovan shares examples from his own career where he surpassed what others predicted based on his apparent genetic profile.
A Balanced Perspective
The episode arrives at a balanced conclusion — genetics matter, but they matter less than most people think, and they certainly should not be used as an excuse to stop working. The athletes who reach the highest levels are typically those who combine whatever genetic gifts they have with relentless training and intelligent programming.
