Year 12/13 Physiology of Fitness

Assignment One – The body’s response to acute Exercise

Handed out Friday June 9th during lesson 1 and 2

Due In Thursday 22nd June 3pm

Name ______

Insert here a picture of your favourite Footballer/favourite team

Introduction.

This part of the assignment asks you to look carefully at the data you have collected for one single bout of exercise. The data will then allow you to look at the responses that take place in response to acute exercise.

You are an elite football player on trial for a top flight football team. They are going to carry out a basic fitness test to assess your level of cardiovascular fitness. You can choose the following machine to do this test on.

1.  Treadmill

2.  Cross Trainer

3.  Rower

The level you choose to work at must be one you can maintain for 12 minutes.

When you start this test your body will make changes to cope with the demands of the exercise. What is meant by an immediate response?

As you are performing the task certain things in your body have to change to allow you to complete the task. Certain systems will have to make changes.

Take each system in turn and describe (Pass) and Explain (Merit) what these changes are.

Skeletal System

Answer the following questions.

What effect does your task above have on / P1 - Effect / M1- Explanation why
The bones
Ligaments
Synovial Fluid
Mobility of the joint capsule

Muscular system

Answer the following questions

What effect does your task above have on / P1 - Effect / M1- Explanation why
Muscle’s work rate
Metabolic activity within the muscle
Temperature within the muscle
Tendons
Risk of micro tears within the muscle

Energy Systems

Describe and explain what happens to the energy contribution as the exercise progresses to 12 minutes. ( Remember at some point there will be steady state activity.)

Respiratory System (P2 and M1)

What effect does your task above have on / P2 - Effect / M1- Explanation why

Work rate of the diaphragm and intercostal muscles as the exercise becomes steady state
Oxygen uptake as the exercise begins
Oxygen uptake as the exercise becomes steady state
Carbon Dioxide production at the start of the exercise
Carbon dioxide production as the exercise becomes steady state
Gaseous Exchange as the exercise begins
