With the rise of competitive all-star teams, official cheer associations, and widely attended summer camps involving intense stunt and dance training, many cheerleaders nation-wide have been putting in effort to reverse this stereotype, hoping to prove that cheerleading can be considered a sport in the process. In case you are interested in seeing Professor Griffith’s mathematics discussed in Post #5…. These forces often cause one object to speed up, or gain momentum, and the other object to slow down, or lose momentum. Just as the legs straighten on the way up, they should bend on the way down. Due to the high-contact/ high-intensity nature of cheerleading, injuries are extremely common and necessitate the reworking of stunt groups. Still, based on personal experience and a look at the graph below, we can at least determine how the coefficient of friction changes the experience of tumbling on certain surfaces, and we can hypothesize which of these surfaces might be most ideal. Hold count three on count four. As a base, it is the athletes' job to protect and catch their flyers. This project isn’t meant to convince you that cheer is a sport – I understand that that argument can sometimes be a hard pill to swallow, especially if you are unfamiliar with successful, hard-working cheer teams. Here, in the North East, cheerleading does not receive the same recognition. (From the Second Law we learned that an object will accelerate in the direction of the applied net force; in order to give the object a negative acceleration, aka to slow it down, we must apply a net force in the direction that opposes the object’s motion.).  The entire process below is described in the website: “Permutations and Combination.” StackExchange. (523/3 = 174.33). The stunt will struggle. As a coach, these are some of the most important techniques for building a strong technical foundation for your athletes. Stunting, tumbling, jumping, dancing: it constantly requires physical activity. * However, she can change the elements of this momentum in order to execute a successful back tuck. She has also participated in outside cheer groups that perform in competitions. Quotes About Cheerleading Top 43 Cheerleading Quotes From . . Cheer Quotes Base Me Maybe Cheerquotes Cheerleading Base I Was A Base When I Cheered In High School Cheer First, the girls must be “lined up” before they can be divided. to avoid this certain problem. Most of us must also push off at an angle and use this angular momentum added to whatever we get generated by our tuck to complete the trick. Various Tumbling Passes on Different Surfaces, The presence of friction in various sports and physical activities can sometimes be seen as an advantage and others as a disadvantage. Cheerleading Bases Quotes Top 5 Famous Quotes About . As we have learned from Newton’s First Law, an unbalanced or net force is required to change an object’s speed or direction. Using this information, we can see that if a person put their foot down on grass, hypothetically it might take them 5 milliseconds to reach 0 velocity. Have your bases watch each other's hands when they are lifting the stunt to ensure they are lifting at the same time. It is the basic job to balance the flyer, so they need to be able to see the flyer and move under the stunt if need be. Still, with the unpredictable weather of Princeton, it is highly possible that a cheerleader might be put in the position of having to tumble in icy conditions. Cheerleading Drills for Bases. The Best Strength and Power Superset for Athletes, Why Nutrition Isn't About Making the 'Perfect' Choice, Quick Cues to Clean Up Your Kettlebell Swing, A Peloton Bike Probably Won't Get You Your Dream Body. Early Sampling: Which is Better? So, in total, we must divide by 4!4!4! However, with the breakdown of each roles, you might end up being interested in trying all three roles! With such a low coefficient of friction, the risk of the cheerleader either slipping on her run or not having enough push-back from the ground to complete her pass is very high. A strong stunt group is nothing without trust, as well. To train strong cores, include abs into conditioning regimens. 11 Feb. 2015. CHEER However, other sports make use of the presence of friction, especially when it comes to grips. It's just how the body is built. The first is that the use of legs is everything. Base I Was A Base When I Cheered In High School Cheer . When the stunt is falling, the bases need to follow the flyer's hips with their eyes and move in the direction of the hips in order to catch the flyer. Thus, tumbling on a turf field, which is filled with rubber pellets, proves to be much easier in terms of push-back provided by the frictional force. The bases are the people who will primarily support the flyer/top girl during stunts. No matter the pass, whether it is a round-off back handspring or a round-off, three back handsprings, full, a tumbler needs a floor that generates enough friction on her feet to keep her bouncing/ moving through the pass. Angular momentum is equal to mass times the velocity distance from the center of rotation (in this case, the tumbler or flyer’s center of mass, around the navel area.) This will not only help the flyer stand up quicker and easier, but the bases are already starting with their legs engaged. Such a line-up mathematically looks like this: This can also be represented as a factorial: 12! Another way to describe this equation is L = wI, where L stands for angular momentum, w rotational velocity, and I moment of inertia, which is related to mass and the mass’ distance from the center of rotation. Conversely, if an object experiences balanced force, it will remain in the same physical state of motion, meaning that an object in motion will stay in motion or an object at rest will remain at rest under balanced forces.. Early Specialization vs.  “Momentum and Impulse Connection.” Physics Classroom. Bases remain on the ground. Her flight into the air is really the reaction force of her feet “colliding” with the upward-moving, action-force “basket” of the bases’ forearms. Web. N.p., n.d. Favourite answer. This friction is good because it helps prevent bases from dropping their flyers. In an interview with the New York Times, a physicist describes the danger that comes with a sports’ surface producing too much friction: “The coefficient of friction of Astroturf tends to be bigger than it is for grass,” Dr. Exercises like planks and hollow holds will make their cores a lot stronger. They are the people on the bottom of the pyramid, who lift, throw and catch flyers or people doing stunts. Doing a basket toss, an impressive cheerleading stunt, requires at least four people: two bases, a backspot, and a flyer. Additionally, the above diagram describes a theoretical and highly implausible situation. In our math equation, this means that we have to divide by 4! Can bases ever have a chance to be flyer? However, all of these options aren’t necessarily logical, realistic, or safe. Tossing, lifting, twisting and catching other girls in the air is not for the faint or weak. Timing and communication are essential in having a solid stunt. She could jump up at a slight angle, providing initial angular momentum, and then tuck herself. Web. Newton’s Second Law states that force is vector, measured in Newtons (N), equal to the mass in kg times the acceleration in m/s^2. 12 Mar. Tips for Bases in Cheerleading. However, this doesn’t mean that the sports that consider friction a good thing always consider it an advantage. Often, the bases of the stunts are the ones who are injured. ‘What that means is that when you plant hard, you’re not going to slip. im not flexible but our flyer isn't either. Make sure you are telling this to your bases. Tumbling in the grass is difficult, no doubt. With the 2014-2015 Princeton stunt team facing an unprecedented drop in numbers (broken hips, intense surgery, concussions, and other extenuating circumstances all contributed), at any point during the season they basically only had 12 girls to work with – meaning they could create 3 full stunt groups of 2 bases, a back spot, and a flyer. Spirit is what every school needs and what every cheerleader strives to increase in their school. Hi, im a base on my new high school cheer squad, im much lighter than the flyer so i want to be a flyer, and i dont like being a base at all. Any skill that can help you catch the crowd's attention and get them cheering along with you is a worthwhile skill to master. * If you are very strong, the initial pull of your legs, using your core, will also generate angular momentum. You’re going to get a lot more blown-out ankles and knees.’”. For spot two, there are only 11 options, since one girl has taken spot one. The bases will pop up and the flyer is going to jump up forward, so he or she can land on the ground. The Basics of Cheerleading Stunts. “Where the Coefficient Meets the Cartilage.” The New York Times. Professor Ian Griffiths proved in the complicated integrals of the section titled “Extra” that the stopping time of a person performing a physical activity that involves friction, such as planting their foot, is inversely proportional to the coefficient of fiction. Web. Like more likely than back-spotters or front-spotters or is it all the same? Bases are the athletes that hold the flyer or top girl in the air during the stunt. To slow down her rotation, the flyer extends her legs, pushing her mass away from center of rotation. With a strong use of legs, any stunt will be made easier. The base is who you will see at the bottom of a pyramid or stunt, lifting the flyer up and holding him or her while they are performing their stunts. Topics: since there are three separate groups. Realistically, I hope that no one would ever consider tumbling on ice. For spot three, there are 10 options. Physics and mathematics can be found everywhere in cheerleading: 8-counts govern a dancing routine; weight distribution determines a three-level pyramid. They should be starting a stunt with legs bent low enough so that the flyer can comfortably stand with one foot in their hands. In today's competitive cheer world, it's crucial for bases … This downward force that the flyer exerts on the bases and back spot is also called the gravitational force. It is also important to note that an extended body, meaning a large moment of inertia, gives the bases more surface area to catch. Stunting, which is when a group of cheerleaders lifts or tosses another cheerleader into the air, can make your cheerleading performances more exciting. Once again, the bases are the foundation of the stunt, and with a solid foundation, you can build anything. Thus, the rotational velocity is large. Each member of the stunt group must do exactly the right thing at the right time or they risk hurting each other, especially the flyer. Rubber, on the other end of the scale, provides 3 times the friction that grass does, as demonstrated by each material’s respective coefficients of friction. Thus, they aim to hold her with a “balanced” force. The easiest way to create good timing is by having the bases watch each other at the beginning of the stunt. Tips for bases in cheerleading? 12 Mar. 2015. Explore our collection of motivational and famous quotes by authors you know and love. In cheerleading, the stunt formation that is used to throw flyers into the air is known as a “basket toss.” This specific trick is called a “tuck basket.” In this stunt, it is commonly said that the flyer is “thrown into the air.” However, what is really happening is that the flyer is pushing off of the bases forearm. Although they will get stronger from basing, the strength doesn't come from muscles. The physical nature of the sport demands a grasp on the knowledge of how both the forces that she exerts and those she experiences will affect her performance in a stunt or trick. There should be very little if any, space in between the two bases once the flyer is in the air. Bases are very important people on a cheerleading squad, even if their positions seem less flashy or dangerous compared to flyers'. In today's competitive cheer world, it's crucial for bases to be strong and fit. Next, the girls must be divided into three groups. Still, by the end of this project I hope that you will at least recognize that cheerleaders must utilize the basic concepts of physics and math in order to be successful in their activities. Clearly, this extra force leads to injuries such as blown out knees and ankles for many athletes. A change in momentum is known in physics as impulse. Junior Claire Jenkins is no exception. The next lowest coefficient of friction after ice, however, involves less risk. https://www.facebook.com/pages/Princeton-University-Cheerleading/123519037710007?sk=videos, Newton’s Third Law states that for every action there is an equal but opposite reaction. LEGS. They also play a vital role in preventing the flyer from injuring herself during the dismount. With good technique, a base can go from just okay to beyond amazing. And finally, a picture of me cheering, to celebrate making it to the end of my Midterm Project! As we can see below, this means that each girl is theoretically holding about 40 lbs. DCBA/ EFGH/ IJKL is essentially the same grouping as found in part 1e. Although I could not find any data for the coefficient of friction on a hardwood gym floor, I imagine that it at times it would be similar to that of ice (although much less extreme.) In reality, the top girl steps near the back side of the ‘table’, so the two middle flyers’ automatically have more weight in their legs, which is more easily supported by the base underneath because of the placement on the shoulders. Once the stunt is in the air, the eyes of the base need to be glued to their flyer. Cheer means to motivate and encourage someone by praising and shouting with joy and Cheerleading is an activity in which participants known as cheerleaders perform an organized athletic skill, dance and chanting to motivate and cheer their sports … When working on stunts, give your athletes time to talk to each other about the stunt and what each of them needs from each other to make the stunt work. Again, in order for the stunt to remain “at rest”, the forces must be balanced throughout the pyramid. No one position on a squad should have more importance than another, Cheerleading is a team sport after all and it takes everyone (flyers, bases, spots) to complete a … In my experience, the glossy finish of the gym floor, combined with the sweat generated from holding pom-poms in my hand for most of the game, makes tumbling on this surface difficult and dangerous. I received a varsity letter for my three years on the Varsity squad. 81.75 lbs seems like a lot of force for just one girl to exert. Spirit. Catch your flyer no matter what. Cheerleading Drills for Bases. 2 Answers. Therefore, the combined force of the three cheerleaders beneath her must equal 523 N, or the stunt will fall. Similarly, stronger girls make better bases – as they are able to exert more force for a longer period of time, and taller girls make better back spots – their height makes them more likely to be able to exert the amount of force needed (1/3 of the flyer’s weight) to keep the stunt balanced. When the flyer does this, the bases will grab her upper arm and her hand. This means that at any one point in the season, the Princeton Coach technically had 5,775 options to group the 12 cheerleaders she had to work with into stunt groups. 2015. Communication goes with this idea, as well. This begs the question: how much friction is ideal for a cheerleader performing a tumbling pass? This exact weight distribution would only occur if the top girl stepped directly onto the middle of the two middle flyers’ backs, and then these middle flyers’ centered their weight directly in between the two bases holding them. The bases and backspot’s combined forces must equal that of the flyer’s downward force, then, in order for the flyer to remain “at rest” in their hands. Rather, a cheerleader with a true knowledge of physics and mathematics will undoubtedly be more successful in her endeavors – such as keeping a stunt from falling, building a pyramid, putting together a stunt group, performing a back tuck, or choosing the right surface for tumbling, which will all be explored in the body of this project. The bases and back spot must be able to supply enough force to balance out the gravitational force of the flyer. In theory we could skip the above steps and figure out weight distribution based on pounds alone, which I will do in the next example.). If you, as a coach, see this happening, this means that the athletes are not engaging their cores when lifting the stunt.
