The effects of aerobic and anaerobic respiration on the heart rate Introduction In this experiment i will be investigating the effects of aerobic and anaerobic exercises on people’s recovery rate. Respiration is a series of reactions in which energy is released from glucose. There are two different types of respiration which will be mentioned: aerobic respiration and anaerobic respiration. Aerobic respiration is a process of cellular respiration that uses oxygen in order to break down molecules, which then release electrons creating energy. In the process, aerobic respiration creates a substance known as adenosine triphosphate (ATP). This is responsible for storing and carrying most of the energy to other body cells [1]. Aerobic respiration can be summarized by the following equation: Glucose + oxygen → carbon dioxide + water (+ energy) On the other hand, anaerobic respiration occurs in the absence of oxygen. Anaerobic respiration involves the incomplete breakdown of glucose. It releases around 5% of the energy released by aerobic respiration, per molecule of glucose. The waste product is lactic acid rather than carbon dioxide and water: glucose → lactic acid (+ little energy) [2] The heart rate during exercise is an indicator of intensity, or in other words how hard you are working. As you get fitter, your heart rate decreases for any given exercise workload. Aerobic exercise has the aim of improving the body's consumption of oxygen whereas the aim of anaerobic exercise is to build power, strength and muscle. The muscles are exercised at high intensity for short durations [3]. Different types of exercises are either aerobic or anaerobic. In the investigation, I will be using four different types of exercises; these include star jumps, skipping, sit-ups and jogging on the spot. Star jumps, skipping and jogging on the spot are aerobic exercises and
