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.

Answer:
What are plyometrics?
Plyometrics, also known as jump training or plyos, are exercises in which muscles exert maximum force in short intervals of time, with the goal of increasing power.
What is one example of a plyometric exercise?
Vertical and broad jumps, Skipping rope, jumping squats, single leg hopping, etc...
What is speed loading?
Speed loading = moving a load as rapidly as possible. • Isokinetic exercise = exerting force at a constant speed against an equal force. CREATING A SUCCESSFUL WEIGHT TRAINING PROGRAM • Choosing equipment: Weight machines versus free weights • Resistance is provided by both types.
What is one example of a speed loading exercise?
Add balance exercises, Leg press, Squat jump, etc...
A condition marked by pain in the throat, typically caused by inflammation due to a cold or other virus!
