Abstract
Explore the fascinating world of energy transfers during sports training, from the energy gained by the body through nutrition to the energy lost through the application of a cold pack. This document provides a comprehensive analysis of the scientific concepts behind these energy transfers, including the role of nutrients, the functioning of cold packs, and the impact of different salts on temperature changes.

[...] to 10 lines) There are two energy transfers related to the coach's recommendations. The first concerns nutrition. When eating a cereal bar, the athlete ingests a source of energy (in the form of nutrients). This energy intake can allow the body to cope with fatigue, making the blood circulation circuit function correctly. The second concerns the placement of a cold pocket. The human body cools down, it loses heat. This heat is transferred to the nearby pocket which it warms up. [...]
[...] Energy Transfers During Sports Training Exploitation of Documents ? What are the substances that provide the body with the energy it converts? How does the body obtain these substances? The substances that provide the body with the energy it converts are called nutrients. The body obtains them through nutrition. ? What allows the energy received by the body? The energy received by the body allows our body to function normally (brain activity, movement, ? What corresponds to the energy associated with a food? [...]
[...] Develop an experimental protocol to validate your hypothesis. (Possible diagrams) Experimental Protocol: - Take 100 mL of distilled water at room temperature using a graduated pipette. - Measure the temperature of the water using a thermometer and note the value. - Dissolve 10 g of ammonium nitrate in the water using a glass stirrer to stir. - Measure the temperature of the mixture and compare with the initial value. - Repeat all the steps of the protocol by replacing ammonium nitrate with calcium chloride and sodium chloride.
