Why is speed important in physical education?

What is the Speed definition in PE? – In sporting terms, speed is the rate at which someone can move all or part of their body when performing a movement or covering a distance. Speed in PE is important as it makes up one of the components of fitness.

  • Being able to move your body quickly is one of the signs of physical fitness, and something we can improve to get fitter.
  • Not all sports are dependent on speed, but there are lots where it’s really important.
  • Most people tend to think about running when we consider speed, but there are so many sports that rely on speed.

Think about examples such as tennis or badminton where you need to quickly move to hit the ball or the shuttlecock. Even sports such as swimming and cycling rely on being quick. Building the skill of speed in PE can really help when it comes to sports skills development.

Isokinetic exercise – These exercise are performed on specially designed machines.These exercies are developed by Perrine in 1968. In these exercise, contraction of muscles applies maximum force only at a particular angle of its range of movement, wheras, in isokinetic exercise contraction of force throughout the complete range of movement,

  1. These exercie involve a specific type of muscle contraction which is not involved in games and sports like rowing and swimming.
  2. Speed, its types and method of development Speed is the rate of motion, or the rate of change of position.
  3. It is expressed as distance moved per unit of time.
  4. Speed is measured in the same physical units of measurement as velocity.

Speed is defined as the ability of an individual to perform similar movements consecutively at Fastest rate, e.g., short distance races like 100 metres and 200 metres. Speed as the capacity of an individual to perform successive movement of the same pattern at a fast rate.

Why is speed important?

This is an excerpt from Developing Agility and Quickness by NSCA -National Strength & Conditioning Association,Jay Dawes & Mark Roozen. – Speed Athletes who can move faster than their opponents have an advantage. For example, a faster athlete may be able to get to a ball more quickly than a competitor or may even outrun a pursuer.

  • For this reason, athletes in most sports value speed highly.
  • Speed is often measured by using linear (straight-line) sprinting over a distance between 40 and 100 yards (37-91 m).
  • However, it is important to remember that in most sports, athletes rarely sprint more than 30 yards (27 m) in a straight line before they must make some type of directional change.

Unless an athlete is a 100-meter sprinter, focusing a great deal of time and attention on straight-ahead speed may not result in optimum performance. On the other hand, since most sports require acceleration from a static state or when transitioning between movements, straight-line speed is still a valuable asset that athletes should focus on when testing and training for sports.

Linear sprinting is a physical skill that most people have performed since their second year of life with some level of proficiency.For decades, many coaches believed that linear speed was mostly related to genetics and could not be significantly improved by training. However, appropriate training does improve running speed, even at the elite level.

The combination of stride rate (the number of strides per unit of time) and stride length (the distance covered in a single stride) primarily determines linear speed. So, athletes can improve linear speed by increasing stride rate while maintaining stride length, increasing stride length while maintaining stride rate, or doing a combination of both.

The body should have a pronounced forward lean that results in a lower center of mass. Consequently, momentum in a linear direction increases. This position initiates foot contact with the ground under or slightly behind the center of mass, reducing forces that cause an athlete to slow down or brake. When pushing off the ground during the propulsion phase, the foot touches the ground in a cocked position, with the ankle flexed upward at approximately 90 degrees (dorsiflexion) and the toes pointed back toward the shin. Once the foot makes contact with the ground, the athlete extends the hip, knee, and ankle simultaneously with as much force as possible (see figure 1.1). This movement is known as triple extension. During the recovery phase, the ankle of the free leg should be dorsiflexed while the knee and hip are bent, or flexed. This allows the foot to pass directly under the buttocks and a more rapid turnover at the hip. The athlete should make certain to initiate arm swing at the shoulder with the elbow flexed to 90 degrees. He should work on swinging the arm forcefully backward to let the body’s stored elastic energy and stretch reflex provide much of the arm’s forward propulsion.

In the propulsion phase, the power output and rate of force development of the muscles that make up the hip extensors and the quadriceps muscles contribute to both stride length and frequency. In the recovery phase of the sprint, the hip flexor muscles (located on the front side of the hip) and the hamstring muscles (located on the backside of the upper thigh) are the major contributors to stride frequency.

  1. The strength and power of the hip flexors are important factors in rotating the hip quickly from an extended position to a flexed position in preparation for subsequent foot contact.
  2. The hamstrings have an important role as a multijoint muscle group.
  3. Because the hamstring muscles cross over both the hip and the knee, they are responsible for slowing down, or decelerating, the lower leg during the recovery phase in preparation for contact with the ground.

At the same time, they also immediately transition to help the hip extend for the propulsion phase of sprinting. In contrast to straight-ahead sprinting, during backpedaling, the hamstring muscles are less active and the quadriceps muscles are more active.

Lateral movements involve more activity from the hip abductors than forward sprinting does. These muscles take the leg away from the body. Therefore, programs focused on improving agility performance should pay particular attention to developing strength in the hip flexors, the hamstrings, and the muscles that surround the hips.

Another important factor contributing to optimum speed is joint flexibility. If the hamstrings are excessively tight, athletes may not be able to bring the knee up as high during the recovery phase of sprinting, hindering hip flexion and speed. Furthermore, tight hip flexors may restrict the ability to extend the hip through the full necessary range of motion, thereby reducing power output during the triple-extension phase of propulsion.

Whats the importance of speed?

Why is SPEED So Important? – If you’ve ever kicked around inside of a weight room then you’ve seen them. You have seen those massively muscular dudes who lift weights to look good for the girls. We call it doing “curls for the girls.” But with all of their size, do you think they can keep up in your sport? Do you think they could compete that well on the field or on the court? Do you really even fear or respect their arms-only muscles? If you have been training the right way, then the answer should be “no.” That’s because you know that static strength is only one part of a large list of athletic skills you should develop in order to enhance performance.

Static strength just gives you the ability to lift weights, move couches and look a little stronger. You need other skills in order to take that muscle and be able to compete at a higher level. And one of the most important skills is SPEED, Let’s break this down so that you can understand it a little better.

There is strength. Good old “curls for le girls” static strength. And on the other end of the performance spectrum there is speed. It is the speed that you are used to. It is the speed that burns opponents down the field. But in the middle of the spectrum, there is power.

  • You need a good deal of lean muscle to develop power, but power is different than static strength.
  • You also need a good deal of speed because power is a blend of strength and speed.
  • Power is your ability to throw all that muscular might into useful velocity.
  • It is your ability to turn your muscles into something more than just guns to be put on display at the beach.

Without speed, you muscles lack power, intimidation and might. They are simply for show and helping friends move heavy furniture. The good news is that you can develop speed with the right kind of fitness training. At Core1, we know just how to blend static strength with high-level speed training to develop the best kind of athlete – a fast, strong and powerful one,

What is speed and power?

Power – What It Is and How to Get It By: Kelly Baggett People usually associate power with the thought of some 300 lb Paul Bunyan looking cat struggling underneath a bar bending load of iron – Or a strongman on ESPN picking up a car on and hauling it across a parking lot – all the while looking like he’s going to burst in two.

  1. When the average person hears the word power this is what they typically think of.
  2. Actually though, power is just as dependent upon speed as it is force,
  3. It is synonymous with speed-strength or explosive strength, the holy grail amongst those who desire athletic greatness.
  4. A sprinter displays a lot of power with each foot-strike into the ground as he accelerates down the track.

A baseball pitcher displays power when he throws a pitch. A jumper displays a lot of power when he jumps. The list goes on and on. In fact, because sports movements rely on a combination of force as well as speed, they inherently require more power and the athletes engaging in them often display more power then the guy who lifts a huge load of iron.

  • Power = Force x Distance/Time
  • That’s too difficult lets simplify it even more.
  • Since the terms force and strength are often used interchangeably and distance divided by time is the same thing as speed, power can more simply be defined as strength multiplied by speed. Therefore,
  • Strength x Speed = POWER

If you draw a line from left to right and write “speed” on one side and “strength” on the other side, power would lie just about smack dab in the middle. Since strength and speed are components of power, increasing one while neglecting the other limits total power development.

  1. For example, if a strength score for an athlete was 2, and the athlete’s speed score was also 2, his power rating would be:
  2. 2(speed) x 2(strength) = 4 (power)
  3. Doubling the athletes speed without altering strength would also double his power:
  4. 4(speed) x 2(strength) = 8(power)
  5. If the same athlete made a 50 percent gain in both speed and strength his power rating would be:
  6. 3(speed) x 3(strength) = 9 (power)

So it should be obvious an increase in power will result if you either increase speed, strength, or both. An optimal balance is the key because having or training for too much of one (speed or strength) will tend to cause the other one to decline, which you obviously don’t want.

Basically there are 3 ways to address power development. You can: 1. Focus on the “speed” side of the line. Examples are: plyometric exercises, loadless (bodyweight) exercises, medicine ball tosses, and weight training using 40% of your max or less performed with great acceleration.2. Focus on exercises that inherently require both speed and strength.

(a mix of speed and strength)These include common exercises like the squat and bench press using loads of around 50-65% of max weight performed with great acceleration, or exercises like the Olympic lifts which inherently require quick execution to perform correctly with loads around 80% of your max.

These also can correctly be called “power exercises”.3. Focus on the “strength” side of the line. This could take the form of 2 approaches. They are: A: Using 80-90% of your max in a given exercise for multiple sets of low repetitions. B: Using 60-80% of your max for higher reps in an effort to induce muscle growth.

Now with so many options to choose from which approach should you follow? It’s really quite simple. The optimal approach requires addressing your weak point, whether it is speed or strength (1 or 3 depending on your weakness) and focusing on your weak area while mixing in optimal amounts of exercises in the #2 middle “power” category that inherently require optimal amounts of both speed and strength.

  • So if you were “speed” deficient your program would best focus on speed training, bodyweight type plyometric exercises, and low load accelerative weight training from group #1 to focus on your speed deficiency; along with performing explosive lifts with 50-70% of your max (group #2 power exercises), while performing enough heavy strength training to maintain your strength.
  • This would allow you to boost the “speed” side of the speed x strength = power equation while keeping the other side constant or even increasing it, which would result in a dramatic increase in power.
  • If you were “strength” deficient your program would have you focusing on strength training exercises (group #3), while mixing in optimal amounts of middle ground power exercises from group #2.
  • This would allow you to boost your strength deficiency and boost the strength side of the speed x strength = power equation, while keeping the other side constant or even increasing it, which would also result in a dramatic increase in power.
  • The result in either case is that you now have greater amounts of power and thus more explosiveness, speed, jumping ability, throwing ability, or whatever aspect of explosiveness you need.

This is how 2 different athletes with the same sporting goals can improve, or arrive at the same point through different training means. Now is that an earful or what? For now I will leave you with that to ponder. In future articles I’ll delve into this deeper explaining how to assess your deficiencies and how to set up an optimal schedule depending on where you should focus your efforts.

Who defined speed?

Who discovered Speed ? Answer Verified Hint: To know about the speed and the discoverer of speed, we should go through the whole concept of speed and we will relate distance and time with the speed to know the presence of speed in the surroundings. Complete answer: The Italian physicist Galileo Galilei is credited with being the first to measure speed by considering the distance covered and the time it takes.

Galileo defined speed as the distance covered per unit of time.Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude.The formula of speed is given in the table below:$s = \dfrac $Here, $s$ is the speed in $m.
