Long term effects of Cardiovascular & Respiratory System

Long term effects of Cardiovascular & Respiratory System & Muscular-Skeletal System




Cardiovascular System

During exercise the cardiovascular systems is called upon to assist the body in many ways, they assist by delivering oxygen to the hard working muscles,blood is then returned to the lungs to be re-oxygenated. 

Another long term effect of the cardiovascular system is the decrease in your resting heart rate it decreases because during the period of time the body adjusts to the exercise sedentary periods become much more easier for the heart to handle making it easier to pump more blood. 

When resting the stroke volume also tends to increase due to the training of the heart being able to pump a large quantity of blood with every beat through out the body.

Circulation also improves due to the demand of more oxygen during the period of exercise, the number of capillaries increase also existing capillaries open up wider. 

The heart also gets bigger and stronger during the period of time this is needed to support the level of blood your heart pumps out with less stress, also making it easier for your muscles to work with out stress as well.   


Respiratory System


The Respiratory System controls the breathing within the body it begins when you draw in air through your nose and mouth. air travels through your wind pipes into both of your lungs giving the lungs a sufficient amount of air to breath in and out.

The diaphragm is the muscle in the body the controls the  respiration contracts when you inhale, when the diaphragm relaxes your chest is forced to release carbon dioxide when you breath in.

During exercise your lungs will start to become exposed to a stronger rush of airflow aerobic exercises in particular expose your lungs to the stronger rush of airflow, aerobic exercise can help clear mucus with in your lungs, mucus build up with in your lungs can decrease the performance of your lungs causing bacterial infections.

During intense exercises the diaphragm becomes much stronger over a period of time making it's self capable of storing a larger amount of air.

Long term effects during long terms your body will begin to adapt to long term exercises by increasing its number of capillaries, capillaries are tiny blood vessels that pass down blood from the arteries into the veins the increase in capillaries in beneficial because when the body will begin to under go a demand of blood the more capillaries there are the more blood different parts of the body will receive.




Long Term Effects Of The Muscular-skeletal System 


- Muscular  Hypertrophy 
Muscle hypertrophy occurs through high chronic Anerobic training at a high intensity such as lifting weights.

Over a long period of weeks (3 - 5) your muscles increase size muscular hypertrophy occurs during the third week of training resistance training sessions it also helps in the increase of muscle size also making them more efficient.

Muscle tone is also beneficial because it makes you stronger over the period of time you've been training, the increase in strength is better because during training sessions you will start to find daily work outs much more easier.

Another long term effect is that muscles become capable to store larger amounts of glycogen for energy, glycogen is a substance stored in the body for later usage when it is needed, glycogen provides extra energy for the body when it is most needed.

  1. You have described the long term effects of exercise for the cardiorespiratory system and explained why the adaptations have occurred. For P3 and M3 you need to describe and explain the long term adaptations to the musculoskeletal system.
    P4 achieved.
