I would say c) increase crash energy because since they are speeding they are more likely at risk of crashing into things or even people.
The cardiac cycle consists of two phases; a period where the heart muscle is relaxed, called <u>diastole</u>, and a period of contraction, called <u>systole</u>.
These are then divided into four stages. These are;
1.<u>Ventricular Filling Period (VPF)</u>
2. <u>Isovolumetric Contraction Period (ICP)</u>
3. <u>Ventricular Ejection Period (VEP)</u>
4.<u> Isovolumetric Relaxation Period (IRP)</u>
At rest, cardiac diastole lasts for approximately 0.5 seconds, and cardiac systole lasts approximately 0.3 seconds to complete. However, during exercise, when the heart rate is increased the time period of <u>diastole</u> , especially, is reduced.
True,all forms of aerobic activity can promote cardio respiratory fitness.
Answer:
Food is broken down into smaller molecules called nutrients. This process is called digestion. Chemical, energy is stored in the bonds between the molecules that make up food. When the body is active, the energy from food is transformed into heat. This energy is measured in calories
Explanation:
Once the food is in our body, we digest it, that is to say, that we break it down to obtain nutrients that the body can absorb. From this process, we obtain amino acids, lipids, and carbohydrates, which are macromolecules that store energy in their bonds. That is why they store chemical energy. When our body is active and needs energy, it will break these chemical bonds and obtain energy. The chemical energy becomes heat, which is the energy that the body can use. We measure this energy in calories.
