Science of Training Young Athletes Part 2

30 个评分

In this course you will learn how to design the type of training that takes advantage of the plastic nature of the athlete’s body so you mold the right phenotype for a sport. We explore ways the muscular system can be designed to generate higher force and power and the type of training needed to mold the athlete's physical capacity so it meets the energy and biochemical demands of the sport. We also examine the cost of plasticity when it is carried beyond the ability of the body to adjust itself to meet the imposed training stresses. The cost of overextending plasticity comes in the form injuries and chronic fatigue. In essence, a coach can push the athlete’s body too far and it can fail. Upon completion of this course you will be able to assemble a scientifically sound annual training plan.

Sport specific strength and power

Training an athlete’s strength and power so it improves their sport performance is a challenging aspect of coaching. Here is the important knowledge you must have: First, you must understand the important terminology such as strength, torque, work and power. Second, you must be able to apply the principle of specificity and transfer of training effects to the athlete’s strength and power development. Third, you must know what peripheral structural adaptations and central adaptations you are trying to accomplish.

Behind me is the University of Florida's state of the art facility for

orthopedic medical care and rehabilitation.

It includes a health sport performance and

human dynamics lab that is a cutting edge research facility.

The most modern technology is used in this lab to help athletes of all levels,

from kids, to recreational adults, to elite athletes.

And to help them gain a greater insight into how they can improve their

performance.

Research that takes place in facilities like this one can help us understand how

and why high levels of training can cause an athlete's body to succeed and

also how it can fail.

Let's take a look inside here and see the research that's going on.

This is Trevor Lavett and he's the sport performance program manager.

And Trevor has a degree in excercise physiology with a specialty in

biomechanics.

And he organizes much of the research that's going on here in this lab.

Now this is a really neat lab, Trevor.

You've got some great projects going on, and I see a treadmill back here.

What kind of work are you doing on this particular piece of equipment?

>> So our treadmill we use it for is mainly to have people run on it.

We do a majority of our running studies and tests for our running athletes.

Our athletes they have their limits that they can push it to, and

many times what we're testing for is a test called the VO2 max.

We push them to their max exertion.

And really test out their limits.

A VO2 marks test allows us, in a controlled lab setting,

to push an athlete to their limits while monitoring metabolism,

heart rate, oxygen consumption, levels of lactic acid, and

even their mental drive to push their body to the max exertion.

From the test,

we can then analyze the results to see how they can improve their performance and

change the type of training they are doing to help them prepare for their events.

We even have the same technology to measure the same results in

real race conditions with our portable metabolic device.

With this, we can compare it to the lab tests and

see how different the body reacts to different elements that it's exposed to.

Whether it be environmental with humidity, rain, temperature, and things like that,

to really test the athlete's performance.

In fact, one of the other tests that we have for performance is

our body composition that we can analyze the person's body and muscle.

Would you want to learn more about it right now?

>> That would be great.

Let's go take a look.

>> Let's go.

Well, here we are with body composition.

Building muscle is a key component of any strength and power training.

Measuring the increase or

decrease of muscle mass is key to any strength training plan.

In a modern sport performance lab we can use the technology of body composition or

a BOD POD device to measure body composition.

The BOD POD uses air displacement technology and

is considered the gold standard of body composition measurement.

It can be used to detect the small changes in body fat and

lean body mass which is your muscle, bones and organs.

Adding this to any strength training or

power program helps measure the success of the program for the athlete.

So do you think bows and arrows are just for kids?

Let's go check out the archery and see what we have going there.

One of our current studies in the lab is focused in youth archers.

We are looking at the body's response to the repetitive stress of shooting arrows,

and the injuries and syndromes that result from the improper biomechanics.

We have archers aim and shoot their arrows to the target.

While the archers shoot, we collect biomechanical data on their shooting form.

From that form we then can analyze and compare the angles to proper

biomechanics and look for possible indicators for injury.

40% of the archers that we have tested have reported shoulder injury

that was related to improper shooting technique and a lack of core and

stabilizing muscles to reduce the demands of repetitive shooting.

Now to really get to the point, let's use our heads and

let's go talk about concussions.

So jumping straight into it, in modern sports performance lab,

force plates are used as common technology.

Force plates can measure the amount of force applied in either a single direction

or three dimensions.

One type of testing used in our lab is a simple box jump landing task,

like I just performed.

This is used to test the ability of the participant to perform a jumping task and

how the body responds to the task.

We measure the body mechanics and also force data during the trials.

We have used this test in multiple studies to test reaction to landing

on different surfaces, assess the possibility of knee ligament injury, and

investigating the effects of concussion on performing the jump landing task.

>> Thanks a lot Trevor.

This is a really interesting place.

Do you have a website where the students can go and

learn more about what's going on here?

>> Yeah, they can just go to UFSportsPerformance.com.

And there's plenty of links on that page that they can learn about the current

studies that we're conducting in the lab.

Also, all the services that we offer to the community for

sports performance type activities.

>> That's great. Thanks Trevor.

We'll put the link under this video clip, students, so you can go and click

on it and take a look at what's going on in a modern sports performance lab.

Wow, what a great lab.

And it's places like this that contribute to our knowledge about how to take

an athlete to their optimum performance.

Now let's move on to the next topic.
