Adidas tm vs. Nike tm : The Ideal Soccer Ball 1 Adidas tm vs. Nike tm : The Ideal Soccer Ball Kevin U. Guevara, Bernie Gabriel, Jesan Morales University of California, Merced

Adidas tm vs. Nike tm : The Ideal Soccer Ball 2 Abstract The purpose of our research topic was to find out which company provides the better soccer ball. The reason why we chose this was because we noticed that many different professional soccer leagues use different brands of balls for example a widely known tournament known as the Barclays Premier League use a Nike tm ball while other tournaments such as the World Cup uses an Adidas tm Balls, so why the difference in soccer balls? Our research team went and set out to look for the answer on which ball is better a Nike tm or an Adidas tm soccer ball. The methods we used to find the answer to the question was providing soccer players from college soccer teams to regular soccer players or anyone in the general public to take this survey and ask them to give their opinion on the company and ball. All the data was collected and then used to compare it to our hypothesis that Adidas tm provide the better soccer balls. Another method we used was interviewing local soccer players and players from the UC Merced soccer team and allowed them to test out two different soccer balls, one being from Adidas tm and the other being from Nike tm. Relating it back to our hypothesis we do believe that many of soccer players opinion is going to be that Adidas tm offer the better ball to play soccer with because it provides a stronger grip and a comfortable touch when controlling the ball.

Adidas tm vs. Nike tm : The Ideal Soccer Ball 3 Introduction: Nike tm vs. Adidas tm, comparing these two industrial giants is difficult enough because of what they represent to the world and the individual. Separating these two companies and just focusing on the soccer division of each company allows us to determine which company provides the better ball. In this research experiment our goal was not to confirm which company is better overall but which company provides the better soccer ball for every soccer player/ individual out there. The reason why this grabbed our research group s attention was because of the different displays of soccer balls out in the world and the controversial debate in the World Cup ball in 2006. The main reason the World Cup ball in 2006 struck controversy was because of the helium being used in the ball. The ball wasn t 100% air; it had a small percentage of helium, which caused the ball to be lighter and giving striker (soccer position) an advantage when kicking a ball. In soccer helium was taken out due to complaints and also because it was noted that it was giving offensive players an advantage when shooting the ball and passing it at a longer distance than usual. Due to the shortage of helium in the world, using helium in our experiment has been factored out and will not be used to determine which ball is better (A Helium Shortage, NY Times). Now that helium is no longer used in regulation soccer balls our group tested which ball would be ideal now that helium is factored out. Why the huge variety in soccer balls? Couldn t we just use one type of ball and spread it across the world so there wouldn t be any disadvantages for any type of players. Despite all that the soccer balls that most consumers purchase are from Adidas tm and Nike tm. Through our research on various soccer stores and examining which balls are purchased the most, we saw that the majority of the balls were purchased from Adidas tm than Nike tm brands. A question we had in the process was what makes these balls so popular to the general public and the answer became

Adidas tm vs. Nike tm : The Ideal Soccer Ball 4 obvious, the consumers wanted a ball that was fashionable yet also serve its purpose as a soccer ball on the field. Noting that throughout history the common soccer ball has changed from being made from a pig s bladder with a grey casing sewn around it to being made from synthetic leather, stitched around an inflated rubber shaped bladder (Football Facts, FIFA). Our group member Kevin Guevara, an avid soccer fan, has been playing soccer since he was in high school. He has been in several teams including UC, Merced Men s intramural soccer team. With Kevin s background in soccer in mind we asked him, what factors make up an ideal soccer ball? According to our soccer aficionado the ball s weight, shape, material, and texture are all important factors that should be accounted for when choosing a soccer ball. This response prompted our group to test both balls in the context of these criteria. The weight of the ball affects the playability of a soccer ball in many ways. It can give the striker a disadvantage in that the ball may be too heavy that, when kicked, the ball wouldn t go as far as it could. Also if the ball is too light the striker may gain an unfair advantage in that the ball may move in an unexpected path of motion. This is the idea behind the helium controversy that was discussed earlier in this paper. The ideal ball would be at a weight where the playability of the ball would be fair to all of the players on the field. Since a huge determinant for each ball is how much they weighed we made them weigh the same (16 oz). This gave the balls the same opportunity to be fairly judged. The shape of the ball is less apparent in its affects in playability. The importance in this is that the ball retains its shape through rough gameplay. The Material of the ball is a very important aspect in gameplay. The material determines the retention of the air in the ball and also the overall feel of the ball. An ideal ball would have material that is comfortable to handle in any situation. The texture of a ball affects the gameplay by providing grip. Grip dictates the control of the ball, especially in situations such as passing, driving the ball down the field and shooting

Adidas tm vs. Nike tm : The Ideal Soccer Ball 5 the ball with a curve. We hypothesize that Adidas tm is the better choice of soccer ball due to the fact that the ball s shape, weight, and material is important factor in the ideal ball. The reason for this is because Adidas is well known to supply Fédération Internationale de Football Association (FIFA) with major endorsements to become the World Cup Sponsors. Adidas being the only company to sponsor 12 of the 32 teams that compete in the World Cup they are the only company with such high numbers. (Nike vs. Adidas, Investmentu.com) Nike being rivals with Adidas are not far behind with revenue sales in their soccer products but as shown in sales Adidas is still in the lead along with the release of their F50i brand shoes. We performed activities with some soccer players to help us reach our goal in proving our hypothesis. Those activities were: Dribble the ball in place to test if the texture on the ball is strong enough for the player s foot control. Also to analyze the material of the ball determining its comfort. Shoot the ball at a target to determine if the weight of the ball has any effect on how a player kicks it. Also to test for the shape of the ball, checking that after the kick there are no deformities. Ask for their opinions (This gave us a more accurate interpretation of which ball they preferred and why). Methods/Materials: An Adidas tm Ball (Jabulani Soccer Ball) (see appendix fig.5) A Nike tm Ball (T90 Soccer Ball) (see appendix fig.5) A four question survey (see appendix fig.1 through fig.4) Camera (Canon VIXIA HV40)

Adidas tm vs. Nike tm : The Ideal Soccer Ball 6 Goal Nets Soccer Cleats or Slip Resistant Shoes Achieving this experiment can be very simple but at the same time difficult because there are always many unexpected factors that can play a part in testing out these balls such as wind pressure or if it s a rainy day. Our research team has decided to perform this experiment on a normal day where high wind pressure and rain are not factors in deciding which ball is better. Now comes the fun part of the experiment. Our group went to the recreation field during a Co-ed Intramural Final for soccer and decided to interview a few UC Merced Soccer players and other players that were their playing around. We gathered players from both the school s soccer team and other individuals who enjoy playing soccer weather it s for fun or just playing in the schools intramural league. On the day of the experiment we gathered four people; two being from the UC Merced soccer team and the other two are average players who enjoy playing soccer. In the experiment we tested out two different balls one being a Nike tm T90 ball and the other one was an Adidas Jabulani ball. With these two balls we made the participants dribble and shoot the ball. The reason for this is that we tried to test out the grip, comfort, texture, and weight of the ball. We made the interviewees tell us how they felt about the ball by testing them out. When we performed this experiment we had set up a small exercise for the interviewees to test out. The balls used in the experiment were the controversial ball the Adidas Jabulani and a Nike T90 ball. We made them dribble the ball to test for the grip and material of the ball and then made them shoot the ball to also test weight and comfort of the ball. When performing this exercise Bernie was recording the interviews while Jesan was recording the sound and Kevin giving the interviews. We gathered 4 participants: Nestor Bravo, Pedro Ramirez, Tony Garcia,

Adidas tm vs. Nike tm : The Ideal Soccer Ball 7 and Elvy Banuelos; to test out the soccer balls and decide which of the two they thought was better. The interviews at most took an hour because the exercise was simple and it still tested out the criteria we set out for the ball. Dribbling the ball tests for grip and material of the ball because, as outline in the criteria the grip affects the control of the ball and the materials affect the comfort. Dribbling the ball exhibits both of these characteristics. Dribbling the ball requires the control needed to keep the ball from dropping and the dribbling also requires the material to be comfortable enough for the player perform the successive kicks on the ball. Along with the dribbling we asked them if the grip and texture was important in the ball characteristics and as predicted they all said yes because it allows them to control the ball better and have a better shot. We asked this question with this test because it complements what is being done in the experiment at the time. Next we asked them to shoot the ball at a distance from the goal. Each of the participant shot both balls in the goal and then gave their opinion on which they preferred to shoot. They all said that they preferred the Adidas tm ball simply because the grip, texture, weight, and comfort were all satisfactory to them. The final thing we asked them was which ball they preferred in an actual game and although both of the balls were in good condition they all also said that the Adidas tm ball was a better fit for a competitive game. For the physical experimentation portion of this project we filmed some of our interviews with the soccer players. Our group member, Bernie Gabriel had some experience in editing and filming. So he took the footage of our experiment, edited and compiled it into a fluid video that can be seen on youtube.com at this url, http://www.youtube.com/watch?v=c3mkwxk_jty. The filming process of the experiment was fun and it added a nice visual element to this presentation.

Adidas tm vs. Nike tm : The Ideal Soccer Ball 8 Results/Data: In our experiment we have two sources that we used to gather the data from. One source is a survey and the other is a physical experiment. In the survey we asked 100 participants several questions pertaining to Nike tm and Adidas tm in their soccer aspect. The first two questions in our survey asked the participant if they considered themselves as a fan of soccer and if they play soccer. These questions let us classify each of our participants showing us the range of variations in our data. Analyzing the results we have calculated that about 66% of our participants consider themselves soccer fans as well as soccer players and the rest were just individuals who just know about sports (see appendix fig.2). The result of this question is very important. Since our entire project revolves around finding the best possible ball to use in official competition it is important that gathered surveys show that more than half of our participants are soccer players or are people who have knowledge of the sport. The next few questions in our survey it asked about the specifics of the two companies, particularly the two most popular sporting goods companies Nike tm and Adidas tm. Our question asks which brand is better Nike tm or Adidas tm. Our survey showed that most people prefer Nike tm over Adidas tm. The percentage of people that preferred Nike tm over Adidas tm was 75% while the rest preferred Adidas tm (see appendix fig. 1). With this question we wanted to know which company people thought was better in a general sense. The results also show an initial bias that our participants had when taking this survey. We then asked the participants which company provides the better soccer ball. When we asked this question we found out that Adidas tm was preferred for soccer balls than Nike tm. The results showed that 52% of our participants prefer an Adidas tm ball over a Nike tm ball. Our final question was does the texture and design matter when choosing a ball? The survey says that it does matter. Many of the participants answered varied on the texture of the

Adidas tm vs. Nike tm : The Ideal Soccer Ball 9 ball; a majority said that the texture and design of the ball does matter while a few said it doesn t because a ball is just a ball. Based off of our survey alone, it seems that Adidas tm is superior to Nike tm in producing the more popular and effective soccer ball in the public s point of view. However, this alone does not make Adidas tm the superior ball. In order to support our hypothesis we must also test the two brands rigorously. This brings us to our next source of data, experimentation. After they completed the experiment we asked them for their opinions on the ball. When asking them which ball they prefer they all said they prefer to play with the Adidas tm ball in an actual game because the grip, weight, and comfort were all satisfactory to them. The Nike tm ball on the other hand was thought of being too light and less comfortable. When interviewing Nestor Bravo we asked him what his thoughts were on each of the balls and he gave positive feedback on both balls but preferred the Adidas Jabulani ball over the Nike T90. Pedro Ramirez another interviewee he favored the Nike T90 throughout the interview but when asked which he would rather play with in a actual game he said he preferred the Adidas Jabulani ball. Tony Garcia who also tested out both balls gave his opinions on both balls but still preferred the Adidas Jabulani. The last participant was Elvy Banuelos her interview was almost alike with Pedro s interview because they both favored the Nike T90 when testing the ball out. As all the other interviews Elvy also favored the Adidas Jabulani ball in actual game. In total our experiment took about a week to gather the survey and the physical experiment took an entire afternoon. Looking at all our data it is evident that all soccer balls are not created equally. Our participants highly favored the Adidas tm ball in most of our set categories. Therefore, using both our sources we can easily conclude that our hypothesis was correct. Soccer players and other individuals prefer an Adidas tm ball over a Nike tm ball. Looking back at the helium controversy, if

Adidas tm vs. Nike tm : The Ideal Soccer Ball 10 helium was factored into our experiment our results would probably only change for the striking test because the weight would be the major factor. Discussion: Some difficulties our group encountered during the experiment were covering the balls. The reason why we say it was a problem is because openly knowing which ball one is testing out could lead to a bias. Our group discussed putting tape on the logo s or painting over the logo s. However, we decided that it would affect the texture or the weight of the ball. Taking into account the variables of our criteria it is difficult to see a way around the initial bias that our participants may have. Painting the ball was a good alternative but not only would it affect the weight, it would also affect the grip of the ball. The best way to approach this would be to account for the bias in the experiment. To do this we could put questions in our survey asking the participants if they consider themselves a Nike tm followed by asking them if they consider themselves to be an Adidas tm fan. Doing this would make the data more accurate by curving the results to lean heavily on the people who answered yes for both questions. Our survey did however, indicate a bias when we asked, Which company do you think is better, Nike tm or Adidas tm? and Which company provides the better soccer ball? The bias shown in this portion is incomplete and to compensate for this separating the questions by showing the Nike tm fans and the Adidas tm fans in separate questions would be ideal. It would be wise to ask these questions before the physical tests of the balls to account for the bias before their choices were made from the test. A concern that our group had is the weather factor, although we tried to set up on a normal day, weather could always be unexpected. For example, on a windy day the participants may have skewed feedback on the performance of the ball because the wind might affect the

Adidas tm vs. Nike tm : The Ideal Soccer Ball 11 trajectory of the ball when kicked. It is suggested that the experiment would be done on a clear day possibly during the spring on a day with relatively low winds. Another alternative could be conducting the tests indoors with a controlled climate. Also on a rainy day the criteria of the ball would also be compromised. The ball being wet could make the grip of the ball less than ideal. On the other hand testing the performance of these balls in certain conditions such as rain would be beneficial for testing to see which ball would be better in less than ideal situations. This test could be added in future experiments to get more feedback making it easier to see which ball is more superior. It is suggested to test the balls performance in simulated wet conditions because testing this could attribute to the superiority of a ball. Also keep in mind the time of day. Due to the limited time our group had to conduct the experiment a lot of testing methods were over looked. After the experiment was conducted our group thought of several ways that our criteria could be tested. For instance, to test the grip we could have asked our participants to palm the ball and time them for how long they could hold it with out it slipping. Our group suggests that these tests be implemented in future attempts of this experiment. Also due to the time limitation we could have gotten a larger sample size with an equal proportion of males and females, which could have changed our results.
