The Math Behind Horse Jumping

Horse jumping is a competitive sport that requires mental and physical skill. If a rider or horse’s timing is off, the results can be dangerous. The math behind this sport requires knowledge of how a horse moves, as well as how the movement and momentum of the horse are affected by physics and math.
A good horse jumping trainer will always stress the importance of the horse’s take-off position. It is the last thing a rider can control on the ground, and the key to a successful jump. An improper take-off can lead to a horse hitting the fence, knocking down the rail, or worse, it could lead to a rider’s fall. If the take-off position is not correct, the horse can lack the

Angle of Depression: this simplifies to… if I then take the inverse cosine, I discover that the measure of angle d, also known as the angle of depression is equal to .
Since I now know the measure of two angles I can simply subtract both angles from 180.
Angle of Elevation: this tells me that the measure of angle h, the angle of elevation, is .
Now that I have determined how a horse and rider should be positioned throughout take-off, I can look at how the horse should be positioned throughout the actual jump. I decided to determine the equation of the parabola of a horse’s jump. I was able to find this photo from a video that perfectly shows how a horses body forms a parabola over a the fence.

This experiment was completed in order to compare calf circumference as well as weight to jump height. If a person has larger calves then they will likely be capable of reaching a higher vertical height. It can also be shown that since males tend to have larger calves, they can jump higher. A larger calf circumference is more likely to reflect a high vertical jump due to the fact that the fat content of the calves in the experiment was accounted for, therefore a large calf measurement in this experiment means a muscular calf. It is common knowledge that more muscle will result in stronger legs leading to a higher vertical.
The announcer calls my number and I walk Jake into the arena and check the calf in the chute to be sure he is the one we are to rope. I back Jake into the roping box and the judge stretches and secures the barrier. (The barrier is a small piece of rope pulled tight across the exit of the box designed to give the calf a 10- foot head start. If the horse leaves early and breaks the barrier, 10 seconds are added to the completion of the run).

Trigonometric ratios are something you would hope to never use, but this term I was forced to find the height of a given eucalyptus tree. No instructions were given for this task other than the fact that I was not allowed physically measure the tree itself. The tools I was given were a large protractor and a measuring tape. I immediately sat down and thought why we were given the specific tools. I soon came up with a theory knowing that If I can find an angle that lines up with the top of the tree (θ) and the adjacent side (length
A standing broad jump is a jump for distance from a standing position. It can be divided into four temporal phases: countermovement, propulsion, flight, and landing. In the countermovement phase, the subject squats to load up and extends the shoulders and the arms. In the propulsion phase, the goal is to generate enough force to propel the body forward. The person must stand erect in full extension of the trunk, hips, and knees. Then, the person flexes at the hip and the knee, which results with the trunk being rotated in a forward direction. Next, the arms become slightly flexed to hyperextension, to full flexion. Prior to the flight phase, the body goes into full extension. The flight phase begins as soon as the feet have left the ground. During this phase, the body stays in full extension or can become hyperextended. Towards the end of the flight phase, the trunk rotates forward in an anterior direction along with minor hip and knee flexion just before landing. During the landing phase, the knees and the hips are in maximum flexion and forward rotation of the trunk. There is also arm movement by moving both arms in the vertical direction to improve jumping distance. At the onset of the jump, the arm swings forward and during landing, they swing back and forth.
The level of athleticism and skill required for a successful vault is overwhelming. Pole-vaulting, a Track and Field event, was introduced to the Olympics in 1896 (The Physics of Pole Vaulting, 2009). The goal of this event is to get over a bar that is set at a certain height using a vaulting pole for a boost. The athlete has three attempts to get over each height; once they have failed the three attempts, they are out of the competition. Athletes that are able to get over the height within the three attempts move on to the next height, which usually increase by 3 to 6 inch increments. Although the vaulting pole is crucial in pole-vaulting, there is more to it then that, all of which play a huge role in how high you get.
There are a lot of misconceptions surrounding the sport of riding horses, including that the horse is doing all of the work. Contrary to popular belief this is false. The rider needs to guide and support all the horse does. The use of abdominal muscles keeps the rider balanced and stabilized. Coordination also plays a major part in horsemanship. To get the horse to do what you want like stop or speed up, a lot of different cues given synchronously to keep the horse from wondering off on its own. Hamstrings, glutes, and quads all work to support yourself upright in the saddle and used as cues to get the horse to turn and move forward. “Straddling a large powerful animal with a mind and agenda of its own is a full body workout that will engage your muscles
The main theories behind why muscle forces accelerate the body upwards greater in countermovement jumps in comparison to squat jumps: a brief review

In fact, a horse’s movement is very similar to that of a human. The motion of the horse not only keeps the patient aware of his actions, but stimulates their senses in order to allow them to think of what they must do, which enables the constant use of their brainwaves. According to Infinitec in the article Hippotherapy, a horse’s rhythmic motion helps stabilize a patient’s condition that in return also improves their posture, balance, mobility, and function (Infinitect). For example, at Heavenly Hoofs each lesson consist of activities that enables the use of the patient’s motor skills. In this case patient A, has a severe case of cerebral palsy. At first patient A had trouble with keeping a firm grip and his back straight, but as the weeks went by he improved. Patient A is now able to bring his leg over the horse in order to moun...
In the beginning of the summer, the pony would not move at all or go really slow when asking him to run the barrel pattern. After many attempts of trying to get the pony to walk with me on top of him, he finally started to get more confidence and knew that I would not let him run into anything while on him. During training, the pony knew the arena well enough so he would not bump into anything. After building up speed and getting better times, I thought that we were back in barrel racing. I entered the pony and I in the minnesota rodeo.

Similar to the height vs. time graph, the dancer’s trajectory in a jump is also a parabola. If the dancer jumps so that the center of gravity rises by two feet, and the horizontal velocity is 10 ft/sec, the path will look like this.
