Dodgeball Lab Report

The value behind entertainment depends on each individual and their likings, implying that not every single human being enjoys playing sports. However, people who do seek enjoyment through athletic activities should know that such vigorous movement can permit various benefits. Competing 5 on 5 on the basketball court involves teamwork and a game plan. The 5 players on each team must create a clever strategy for allies to follow through on court. Possibly achieving a blind pass, jab step or block can make a victorious battle. Communication, team cooperation and interpreting the opponent’s next

In her article, Michelle Voss explains that professional athletes have better-developed imaginations. Research showed that the excitable part of the mind in elite basketball players while watching their competitors was the same area that controlled their shooting hand. Voss explains that the basketball players subconsciously pictured themselves doing their opponents’ moves in order to produce an accurate prediction of the outcome. In doing this, researchers concluded that the players were able to predict free-throw outcome within 30 percent accuracy while expert viewers were only able to make predictions within 10 percent accuracy (par 5).

The task that will be performed in the lab is a football snap toward a target. The subject will face way from the target, place their feet about shoulder length apart, place the ball between their feet, bend over and snap the ball through their legs to hit the target. For the experiment, the target is a wall. The wall is marked in increments of 20cm; a center space with five spaces above and below.

When a pitcher throws a faster straight ball, a batter, his opponent, is less likely to hit the ball, because he should prepare for the second pitch, maybe a slow breaking ball. After getting used to the eyes in the fast ball, a batter is hard to react to slow ball.

When two people run up and down the basketball court for 10 minutes, they were sweating. The body also loss much fluid, sugar and electrolytes. After running, their reaction time are similar, around 21,7 – 35,7. Next, one person drink 200 ml of Gatorade and another person drink 200 ml of water. After running, they measure the reaction time again. Person who was drinking water, has higher reaction time (left hand : 18,3 ; right hand : 28,3). Person who was drinking Gatorade, has lower reaction time (left hand : 9,0 ; right hand : 16,3 ).

Hawk-eye is a simulation which is provided by numerous cameras. By tracking the flight of the ball and projecting its path, Hawk-eye is able to triangulate the ball’s potential location. Sport has been notable throughout the years of attempting to eliminate human error using technology, in order to deliver fair sport to the public. The brand has continued to grow extremely quickly, and is synonymous with modern day sport. Initially used in Cricket at the turn of the century, it has spread to numerous sports, most recently football. Whilst both are at differing ends of the spectrum, in terms of experience in the game, they draw huge contention within the media and amongst players. Fallibility is a matter discussed widely in sport, and not just in Tennis. This report will thoroughly examine the article 1by Suzi Gage and discuss the claim presented that Hawk-eye is not as infallible as people think. Therefore, the accuracy of Hawk-eye, its weaknesses and any potential advances that would help progress the technology used in sport will be discussed. Gage bases most of her article findings on the journal by Harry Collins and Robert Evans2 and the Hawk-eye website3, both of which will be thoroughly scrutinised in order to best determine the validity of the claim.

Dodgeball is an important part of students health. First of all, dodgeball benefits hand-eye coordination. Players have to catch and throw. They need to throw accurate, but also know where they will need to catch near them. Second, this activity improves flexibility. Dodging the ball improves the body’s flexibility when jolting out of its way. Dodgeball also includes the release of endorphins. This means happy chemicals are released from the body and that makes you happy.

The goal behind this experiment was to estimate the distance a ball would travel after it falls a certain distance and bounces off a metal plate which has an angle of 45 degrees. To find this we had to take the basic equations for kinematics which are (1/2)at2=x and v=v0+at and combine them to make an equation that will help us solve for the distance the ball will travel after hitting the bounce plate. The equation came out to be R=g*(sqrt(2)/sqrt(g))*(sqrt(H)*sqrt(h)), as that g is acceleration of gravity, h is the height of bounce plate, and H is the height of where the ball will be dropped. After completing this experiment the result was that the standard deviation was +/- 2.3 cmfrom the

Land (2009) suggests that three executive systems are responsible for visually guided movements, namely gaze, vision and action, and these are overseen by a fourth system labelled the schema system. Figure 2.12 is an illustration a particular model that has been developed to explain visually guided movement in natural environments, so it is relevant to sport.

In the Bouncy Ball Lab, my team conducted two experiment that looked at how rebound height was affected by different independent factors. In the first experiment, we chose six different starting heights and measured the rebound height in order to calculate how bouncy our given ball was, also called the rebound ratio. We then graphed our data and found an equation to model the relationship between starting height and rebound height. In the second experiment, we allowed our bouncy ball to continue bouncing after an initial height of 200cm. Again, we graphed the rebound height as the dependant variable on the y-axis, but our independent variable was the number of times the ball had bounced. we also found an equation to model this relationship.

During recess, "W" was observed about three times per week during the observation period. Recess is always outside rain or shine and there is not a choice to play inside. During almost every observation, "W" was playing a game of four square with the same group of three boys. He seems well-coordinated. School-aged children are usually quite skilled at controlling their bodies and are generally good at physical activities (Davidson 2011). He was able to hit the ball without being too clumsy. "W" usually moves quickly outside. At this age, children’s large motor

The horizontal displacement (in centimeters) of each throw in each condition was measured. Researchers found that during the PRE trials, the younger adults performed better than the older adults. When the prism goggles were first put on at the start of the PRI trials, accuracy decreased for both age groups. However, this decrease in accuracy was larger for the older adults compared to the younger adults. As the PRI trials continued, the younger adults’ accuracy improved faster compared to the older adults’ accuracy. For both age groups, there was an aftereffect when the prism googles were removed at the start of the POS trials. This aftereffect was larger for the older adults. Finally, the persistence of this aftereffect was longer for the older group compared to the younger group (i.e. the aftereffect lasted longer for the older adults). These results support the theory of visual-motor adaption. For both age groups, there was evidence of adaption to the prism goggles. When the prism goggles were first put on at the beginning of the PRI trials, there was an initial decrease in accuracy for both age

snooker cue balls and they were painted with spray of matt colors {black, gray, white (achromatic)}and {blue,red,green,lilac and turquoise (chromatic)}. The design was connecting each ball with every other balls to have 28 pairings. Every participant completed 2 blocks of trail and in one block they indicated which was the heaviest and in the other block they indicated which was the lightest. Procedure was all the participant has indicated the weight in 3 conditions, first the vision and they were not allowed to touch the ball. Second, participant hefted each ball while they were still looking at it. Third, by using their thump and first finger of their right hand, they hefted the balls in any sequence and as many as they wanted but the ball was hid by black curtains.

The accuracy of a person can be improved by playing video games that involves shooting and aiming at other objects. Shooting in a game is similar to shooting or throwing objects in real life. It takes predictions and precision. Not only in video games, but accuracy is a very important key factor in many sports as well. For example, soccer requires aiming the ball at a certain angle or direction to pass it to another player. (Frankl, 2000) This compares to the weapon shooting a bullet at a certain angle or direction in order to “snipe” another playing running or jumping. A group of participants helped with a study at the Ohio State University to test whether shooting games helped improve a player’s accuracy in real life shooting. In this experiment,
