Introduction
A vertical jump test is used, both by athletes and the general public, to determine a variety of functional actions. For example, it is commonly used to determine the development of elastic leg strength (Mackenzie, B., 2007), jumping ability and it may even be used to asses recovery prior to or post-training (Baggett, K., 2004). In this investigation, the vertical jump test is being used to determine whether there is any correlation between leg length and vertical jump height. The vertical jump, sometimes known as the Sargent jump test, can either be performed from standing as is in this investigation, or as a running vertical jump test which allows a run up prior to the jump.
To perform a vertical jump, there is both hip and

Then, using the tape measure, the length of the leg was measured from the hip to the heel of the foot. The length of the leg was then recorded. The participant raised their hand and the vertical leap test equipment was adjusted accordingly. The participant then jumped and hit the measuring component of the vertical jump equipment (see diagram 2) and the height reached was recorded. This process was then repeated a further three times for each participant.
Ethical And Safety Considerations
The primary safety concern during this investigation was injury due to the nature of the investigation and improper use of the equipment. There was potential for muscle injury during the phase in which the participant was jumping, and improper use of the equipment could potentially have caused injury such as concussion. As a precaution, the investigation was conducted in a location where first aid officers were available and the equipment was placed on a level surface and the participants were told how to use the equipment.
Participation in this investigation was voluntary, all results were kept anonymous and the participants had the
To ensure the proposed study is academically, professionally, and ethically sound, researchers shall complete a risk assessment on the proposed method (participants, materials and design) of the study. This risk assessment will form the basis of the application to Swinburne University’s Research Ethics Office for ethical review. This application will address the risks identified with the participants used, including recruitment and informed consent, as well as data and publication arrangements.
To test the athletes' strength, they will be required to perform 1 repetition max on the bench press, squat, dead lift, clean and vertical leap. To test the athletes speed they will be tested by performing a forty-yard dash. To test the athlete's agility, they will be required to perform out the t-test, hexagon test and pro agility, for time. To test endurance, the athlete will be required to perform a mile run for time. At the end of the third cycle of the off-season, the athlete will be tested again to perceive how much strength gain, increase speed, agility and endurance was achieved and it will determine the changes should be made for
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 study design of the research took place within a span of nine weeks. Before and after the nine weeks of resistance training, several tests were administered to determine the level of muscular strength, jumping ability, sprinting ability, RFD, etc. as they were all much needed requirements specific to the job of firefighting. Other factors were also considered, including height, mass, and size of limbs and chest. Upper and lower bodies of the participants were measured via barbell squats and bench press exercises, using the 1RM method until failure. The values were then recorded. Jumping ability was measured using both vertical and horizontal jumping exercises performed in three to five trials. Warm-ups were performed before the test. RFD or rate of muscular development was measured with a calibrated position transducer which utilized the three values from the upper and lower body 1RPM tests. A TENDO unit cord was used during these tests. These tests were administered throughout the span of over a week in
Running, it is the simplest of movements: right foot, left foot, right foot, and the simplest of actions: run, relax, and breathe. Many individuals participate in this form of exercise because they enjoy how good it makes them feel, they enjoy feeling the strength of their body while they run, and they enjoy using it as a way of relieving their stress. There are many other factors to take into consideration that effect a persons running such as, the type of footwear they are using, the distance they are running, and the speed of which they are running at. The objective of the main article was to research and compare the differences in stride length, hip, knee and ankle angles in runners when running two different conditions, shod and barefoot, also while running at two
During World War II, many of the American peoples were terrified about the war coming on to United States soil. Homeland security was at a high concern in the standard American home. The War was a prime time for the United States military to get the average able bodied man to get to work and fuel the military power. The purpose of this propaganda was to get people scared into working for the government to produce weapons and war supplies for the troops overseas. The imagery displays Adolf Hitler and Emperor Hirohito surrounding the United States mainland as if they were going to conquer it. With the text “Warning! Our homes are in danger now!” was to frighten people and to increase the amount of production in the United States. This poster was also a campaign by the United States Military to increase
Respect for human dignity includes two rights; the right to self-determination and the right to full disclosure. When conducting a research study these two rights must be maintained to ensure that the participants are not coerced into participation and that they are making the choice of their own free will. Patients must be provided with all the information necessary to make an informed decision and voluntarily participate. No deception or concealed data collection can be done because it will violate the patients’ rights.

Provided to each subject was a consent form to review and sign before their participation in this study. The researcher excluded any identifiable information from the data collection measures. Subjects received a number as they signed in for the information session. The researcher used these numbers to link the subjects to their surveys and their clinical assessments. Their numbers coordinated with the attendance form which was in the sole possession of the researcher. Institution
Unlike most studies and tests that measure and examine jumping ability and leg muscle power, the vertical jump test is extremely inexpensive to conduct. Although the vertical jump test is simple, easy, and quick to perform, there are numerous disadvantages to the test as well. In the vertical jump test, an individual is asked to attempt to touch the wall at the highest point of their jump. When the individual jumps, their technique and form play a large role in maximizing their jump height. The jump height can be affected by not only how much the individual bends their knees before they jump, but also by how effectively the individual uses their arms.
Summary: The objective of this study was to determine how muscle strength and speed differences of rising from a chair differ from elderly and young women. The subjects examined in the study consisted of two groups, 26 healthy elderly women and 12 heathy young women. There were six trials done, three trials at normal speed and three trials at fast speed. The study involved examining the muscle strengths of the individuals and preforming the actual task of rising from a chair.
Paying college athletes would negate the whole point of a college. Colleges give many citizens across the country a chance to gain an incredible education that will aid them in their life. Colleges accept every person of any age to attend. Sometimes it may be middle aged citizens looking to go to school after waiting years to make a decision, and sometimes it may be a recently graduated teenager out of high school. No matter who it is or where they came from, colleges allow anyone to gain an education that fuels their interests and helps them obtain a job after they graduate. Although most students focus on getting an education, there is a significant amount of students, known as student-athletes, that focus only on playing sports. Through the years, men and women of America have created a controversy surrounding these student-athletes and the colleges they are currently attending. The argument is whether or not colleges should pay their student-athletes for their labors and contributions they give their teams and schools. Citizens of America love college sports.

According to Morgan Freeman (2012), “Marijuana prohibition is just the stupidest law possible...just legalize it and tax it like we do liquor”. Canada has illegalized marijuana in 1923.Since then marijuana has been the most used drug among Canadians .Moreover, Canada has the highest rate of marijuana use in the world. Therefore, many Canadians argue that the time that marijuana gets legalized in has arrived. Marijuana has been proven to be very beneficial to the country. Legalizing marijuana will reduce crimes, benefit the economy and help individuals medically.
Forty surveys were completed successfully which resulted in very conclusive answers.
