Observation on heart and breathing rate

Introduction:
Exercise is crucial in sustaining a healthy lifestyle. For instance, exercising on a daily basis can increase muscle and help manage weight. Also, exercise can lower cholesterol levels in blood and lower the risk of type 2 diabetes and some cancers. Moreover, while exercising the respiration rate increases because he/she has to expel the carbon dioxide produced by the muscles. Additionally, sweating is used by the body to keep it from overheating and is a great way to get rid of dirt and toxins which are gathered by pores in the skin. Furthermore, Homeostasis is the ability to maintain a constant body temperature in response to environmental changes. The nervous and endocrine systems control homeostasis in the body through feedback mechanisms. Recovery time is a very good indicator of your fitness level. Recovery time refers to the number of beats the heart drops during 1 minute immediately after exercising. In general, the heart rate of a fit person will drop more quickly than that of a less fit person. Likewise exercise causes a person’s heart rate to increase this because the body needs the heart to carry out functions much more rapidly while exercising. Nevertheless, the variables controlled in this experiment included, the intervals at which the athlete’s heart rate and breathing rate were checked and the distance (the width of a class room) the athlete had to run was kept the same. The variables that were measured were the person’s heart and breathing rate and also their production of sweat as the person exercised. In summary exercise can do a number of things to benefit us and is essential for us to exercise in order to remain healthy and strong.
Aim: to investigate the rise in pulse and breathing rate when exercising and the time taken for the pulse and breathing rate to return to normal as well as the

    Introduction- This experiment was conducted in order to use a parachute to reduce the collision force by decreasing the acceleration of which the water balloon is traveling causing it not to burst. When the balloon was dropped without a parachute the force of gravity was pulling it towards the ground therefore causing it to accelerating at such a fast rate that when it hit the ground the amount of force it hit the ground with was so great that the balloon popped. However when the balloon was dropped…

    Introduction Gravity is a force that pulls all objects on Earth to its surface at a rate of 9.8m/sec. Gravity is an acceleration of a free falling object (Encyclopedia Britannica, 2014). Gravitational potential energy (Egp) is a concept from the law of gravity. As an object is positioned with a gravitational field, the object can store energy which is called gravitational potential energy (Physicsclassroom.com, 2014). As the object begins movement or work the energy transfers into kinetic energy…
