Measurement of upward force exerted by a human on a vertical jump?

[heisenbergman]

Hi,

I'm doing some research on developing a physics-based platform game and I want to see how the gameplay will feel if the environment and physics were made to scale as realistically as possible.

Since one of the core features of a 2D platformer is jumping, I need some figures on how much force is actually exerted when a human jumps vertically.

Are there any resources regarding this?

Thanks!

Well, first of all it depends on 1) the mass (in Kg) of the person jumping, 2) the gravitational potential that the person is jumping through (is he on the Earth, the moon, Mars?), and 3) the acceleration of the person due to the jump. After you've identified those parameters, I think all your going to need is Newton's handy old F=ma to get your answer. As far a resource related to gaming algorithms, I am unaware of any, but I'd imagine they exist "pre-fabbed" somewhere, its a common feature in many games even though I'm not a gamer.

It's not going to be much of a platformer if the character can't jump 2-3 times his height. A human can't even jump 5 feet in the air from standing, but Super Mario jumps 3 times his own height.

Anyway, why don't you stand on a scale and jump to see how much force you exert on the ground.

I understand your interest in accurately representing the physics in your platform game. The measurement of upward force exerted by a human on a vertical jump is a complex topic that depends on various factors such as the individual's weight, height, and muscle strength, as well as the technique used for jumping. However, there have been studies conducted on this topic that can provide some insights.

One study published in the Journal of Strength and Conditioning Research found that the average vertical jump height for male athletes was approximately 18-20 inches, with a maximum force exerted of around 3,400 Newtons (N). For female athletes, the average vertical jump was around 13-15 inches, with a maximum force exerted of approximately 2,200 N. It should be noted that these values may vary depending on the specific population being studied.

Another study published in the Journal of Applied Biomechanics looked at the force production during vertical jumps in both athletes and non-athletes. They found that the average peak force exerted during a vertical jump was around 2,000 N for both groups.

In terms of resources, there are various online calculators and tools that can estimate the force exerted during a vertical jump based on an individual's weight and jump height. However, these should be used with caution as they may not account for individual differences and variations in technique.

Overall, while there is no definitive answer to the exact force exerted during a vertical jump, these studies and resources can provide some general insights and guidelines for your game development. It may also be beneficial to consult with a biomechanics expert for more specific and accurate measurements. Best of luck with your research and game development!
