In the art of self-defense, a practitioner remains filled with a list of tasks that they need to accomplish. With that being said, martial arts require students to endure countless hours of perfecting their moves. Not only do martial art students have to master their offense moves, they also have to master their defense moves. However, it remains a difficult feat to accomplish. In particular, Brazilian Jiu-Jitsu remains one of the world's most effective martial art techniques. For those unaware, Jui-Jitsu began in the early 1900s. To expound further, Geo Omori founded the first Jui-Jitsu school in Brazil. With that being said, the art of Jui-Jitsu has several methods of fighting. However, some of the most premiere methods of fighting include the double leg takedown, throws, and the single leg takedown.

For example, the toe poke kick only gets contact with your toes, which could affect the accuracy of your kick. The distance will never be changed no matter what kick style you use. That is because the power of your kick never matters on how you kick the ball. But, the soccer style kick you use your entire side of the foot so you have more of a chance of kicking the ball straight.

*John Guido and Sherry Werner make a point that “The stride leg functions to dynamically stabilize the hip and knee joints in a single leg stance to maintain standing posture for

When listening to a song no one ever pauses the music and thinks about the true meaning behind it. Several songs have meanings but some of the artists produce those songs to create an awareness. “Pumped up Kicks” by Foster the People is a song the band created to raise awareness of school shootings. I have always listened to this song, but I never found out the story behind it until this year. Listening to this song now has changed my perspective on listening to music. Songs have a reason for everything, and to have an issue come out of it is a great way of listening to it.

“The analysis of movement provides an athlete with optimal development as well as minimising the risk of developing injuries through the incorrect execution of a movement” (Ackland, Elliott & Bloomfield, 2009, p 301).

Punting a football can be intensively and precisely explained through the study of structural kinesiology. Punting is a skill that is often referred to as kicking. It is performed by releasing the ball from the hands and kicking the ball before it strikes the ground. Punting is an action that takes place in the sagittal plane around the frontal axis. The joints involved are the: atlantooccipital (cervical), intervertebral (lumbar), scapulothroracic (shoulder girdle) glenohumeral (shoulder) humeroulnar (elbow) radiocarpal (wrist) metacarpophalangeal and interphalangeal (fingers) acetabularfemoral (hip), tibiofemoral (knee), talocrural (ankle) and the metatarsophalangeal and interphalangeal (great and

The physics involved in soccer includes friction, torque, center of gravity, Magnus Effect and Newton’s three laws of motion. The physics of soccer comes from three main parts of physics which is velocity, acceleration, and displacement. Velocity is shown in soccer with the speed and direction of the soccer ball when it is hit or kicked. Acceleration is shown in soccer when the ball changes velocity when it is hit or kicked. Displacement is the change in position of the soccer ball.

The crow hop is a technique used by outfielders in baseball and softball for long distance throws when the athlete must make a strong, accurate throw to a base or cutoff man to either keep a runner from advancing or in an attempt to get the runner out. The crow hop allows the athlete to put maximum speed on the baseball in an attempt to cover that long distance as quickly as possible. The crow hop utilizes a hop or lateral jump to reduce the distance of the throw and help the athlete generate momentum and force. The end goal of the crow hop is to limit opportunity to advance to extra bases by the opposing team.

When you see a dance team at a football game you will notice the uniforms and makeup, but the kick routines will definitely catch your eyes. I imagine that you think to yourself, “Oh, that’s easy. Anyone can do a kick.” But doing a kick is not as simple as it looks. There are several steps involved before a dancer can get it perfect: getting comfortable, stretching efficiently, positioning correctly and kicking perfectly.

The distance that you are able to kick the ball can be summed up with the equation for distance, d=RT, distance equals rate multiplied by the time. So speed and time are both very important when kicking the ball because it directly affects the distance. Soccer players vary the distances that they want to kick the ball. Skilled players can estimate very quickly how fast to make the ball move to make it go where they need it to. Before learning this equation in physics I just thought you kicked the ball, but now I know that when this equation is applied to soccer it means so much more. Soccer players can use this to help them judge how hard and fast they need to be able to kick the ball to make it go a certain distance. This is just another example of how physics, the small details, can be used to improve ones soccer skills.

The placement of the non kicking foot determines the direction of the kick. The support leg also acts as a stabilizer by flexing at the knee once the foot makes contact with the ground. (Lees, Asai, Andersen, Nunome & Sterzing, 2010) Pictured below in Figures 1 and 2 are two different athletes with very diverse abilities. You can see both the direction of the planted foot and the flexion of the knee in both players.

Because this is a stable stance, the various forces acting on the body must be equalized somehow. The main force is the one caused by extension of the back leg into the ground (a). This is held in check by dropping the torso into the stance and allowing the friction on the front foot from the ground, μb + ~(1/3)μmg where μ is the coefficient of static friction, and b is the force of the body attempting to move forward due to a, and the tensing of the front leg quads to keep the stance in place. If the stance is correct, this force is easily released to throw into techniques, either by using it as a spring to pull the reverse leg forward for a kick, or by rotating the body or otherwise neutralizing the check imposed by the front leg to throw some other technique, such as a punch.
