While exercising with a friend can make it more motivating and fun, beginning a new exercise program requires a visit to your doctor.
The physician can help and guide you in assessing your fitness level and recommend (if necessary) you to professionals that will help in designing your fitness program. The doctor can also help monitor your progress and may assist in adjustments.
Please explain further as I can not answer this question without something to pick from.
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.
