Introduction

Josh Keen Unit 1: The Body in Sport Energy Requirements Scenario, As a work experience student at the local gym you have been asked to produce two information posters for the gym users showing: 1. The energy requirements of 4 different sports. Task. Produce a table to show the calories used in four different sports. (works out the calories used per hour whilst playing) explain why each sport is different. Criteria. M6 Explain the energy requirements of four different types of physical activity. Date set: Date due: Different activities require different amount of energy depending on the amount of muscles you are using. If you are using only three groups of muscles, your body won't need as much energy as it would if you were using five groups of muscles. ...read more.

Middle

This means your body needs to use more energy which means you burn more kcals off. Your body would use the aerobic energy system as the body lasts over 10 seconds and needs a constant supply of oxygen. 100m sprint which lasts around 9 - 12 seconds requires about 20kcals of energy to perform this activity. In a 100m sprint the amount of calories that you burn can vary because of the weather, rain, wind, etc. also it can depend on the clothes you are wearing such as: your trainers may not have metal spikes so your grip may slow you down and meaning you will have to work harder for a few milliseconds longer. ...read more.

Conclusion

The reason why you switch to the aerobic energy system is to get oxygen going around the body and removing the waste products from the body so you can start exercising again. The amount of calories you burn can vary as in a 400m run the conditions may be different such as: wind, rain, clothes and snow. Cycling burns 530kcal per hour and uses the aerobic energy system as it lasts over a minute. The amounts of calories you burn vary as the weather conditions change. If it's raining the wheels will have less grip so you will have to pedal faster. Also the terrain can affect the calories you burn due to harder pedalling as you are going up hills which results in trying harder and working harder. ...read more.
