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 whyThe 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 whyMuscle’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.)
