Health related components of fitness

This article is going to look at the health related components of fitness. This is the first point for what is the for the critical question what is the relationship between physical fitness training and movement efficiency? The syllabus for this point asks you to learn about cardio respiratory endurance, muscular strength, muscular endurance, flexibility and body composition.

You learn to to go along with this ask you to analyze the relationship between physical fitness and movement efficiency. And you're going to do that by considering the question to what degree is fitness, a predictor of performance, or you also have to learn to measure and analyze a range of both health related and school related components of physical fitness. And you also need to think critically about the purpose and benefits of testing physical fitness. So the health lady components of fitness are essentially going to be the foundational components of fitness. These are the ones are going to form the basis for any kind of training for any sport to get the athlete ready to go. Normally focused on in the preseason. cardio respiratory endurance is also known as cardiovascular endurance or aerobic fitness. This refers to the body's ability to maintain movement for an extended period of time. It is essentially your heart, lungs, blood vessels, and your muscles all working together to absorb deliver and utilize oxygen in the production of energy, which enables you to move so in other words, this is how well the cardio respiratory system works which you learned about in the last critical question. The cardio respiratory endurance is all about delaying fatigue. It allows for a higher intensities been maintained for longer when it comes to performance.

When you try and measure cardio respiratory endurance, you're going to try and use something like a beat test or you might do a v two max test. When we found a muscular strength, muscular strength is the maximum amount of force that a muscle can produce in one contraction, okay, so don't get confused with muscular endurance muscle strength is one contraction and it's a maximal contraction or greater strength means less effort is needed in order to produce particular movements and to produce a given amount of force. So that obviously beneficial in performance because you are perceiving to be exerting yourself at a lower rate. So I've rated perceived effort relates closely to fatigue. And so muscular strength improve improves movement efficiency by delaying fatigue, it can also improve technique and reduce the chances of injury to the athlete. muscle strength is measured by doing a one RITE one RM or repetition Maximum, or you can use a dynamo meter to do some testing. muscular endurance on the other hand is a muscles or a group of muscles ability to repeat a specific movement over again, muscle endurance is tested using how many times an athlete can perform a specific movement in a set time. So for example, you might do push ups or sit ups How many can you do in one minute? muscular endurance improves your body's movement efficiency, because it helps to delay fatigue, particularly the fatigue there's that burning fatigue in the anaerobic system, particularly that lactic acid buildup. So if you have good muscular endurance that lactic acid buildup takes longer to happen, and that allows you to maintain good posture, good technique for a longer period of time. muscle endurance is tested using a range of different tests, but essentially, you're going to ask the athlete to do as many of something as they can in one minute or until they reach fatigue, whether that be like push ups or sit ups, and those tests are often specific to muscle or muscle groups. When it comes to flexibility, flexibility is the range of motion or movement at your joints, and refers to your body's ability to move freely. Flexibility is joint and or muscle group specific. So if you're flexible at your shoulder, that doesn't mean you can be flexible at your hip flexibility helps to prevent injuries. It is going to improve your posture it's going to decrease back pain, maintain healthy joints, and improve balance during movement. This results in improved movement efficiency through better bio mechanical movement. It's in order to measure flexibility you might use something like a sit and reach test but as I said, each test will be specific to the joint body composition is the different tissue types that make up a person's body and usually focuses on a person's percentage body fat that can be used to determine bone muscle and water composition percentages as well. Now body composition is sports specific as well. So less fat means that you have less weight to move around, allowing you to move for longer periods such as a marathon or allows you to accelerate faster in things like the 100 meter sprint or in football. However, you might want a larger body mass because that means your heart to move, so things like wrestlers as sumo wrestlers or NFL blockers, for example, they want to be quite large so that the other person is has to exert more force in order to move them.ideal body composition is going to be specific to the sport and can improve movement efficiency. As per the examples given.

Body Composition is tested by skin folds, or by using underwater weighing when it comes to testing and performance testing is only good at predicting performance when it is specific to the sport. So for example, if you do strength testing, muscular strength testing, after a weightlifter is going to be really good at predicting performance. If you do cardio respiratory endurance testing for an Iron Man, that's gonna be really good at predicting their performance. But once you move to sports that combine multiple components, especially skill related components, our tests become less accurate in predicting performance. So for example, strength testing a rugby forward helps identify if he's strong, but does not tell you if he can tackle correctly doesn't even catch a ball if you can do repeated movements over and over again for any good length of time. This requires other testing and still will not account for the ability to read the play, or for following instructions from the halfback, all the other things that our forward needs to do on the field to be a good player.
