SOC 9 Flashcards
Aeronic exercise
working at a moderate intensity level with oxygen
Anaerobic exercise
working at a high intensity level without oxygen.
Effects of the musculo-skeletal system
When someone gets fit, you can often see that their muscles are toned and they look
strong. Exercise brings a number of benefits for your musculo-skeletal system – some
of which you can’t see
Effects on the cardio-respiratory system - your heart
Decreased resting heart rate: Your heart gets bigger/ stronger with training
Faster recovery rate: Heart recovery rate is the speed at which your heart returns to RHR after your exercise
Increased resting stroke volume: stroke volume is the amount of blood pumped by your heart per beat.
Maximum cardiac output : the amount of blood ejected from your heart in one minute
Size and strength of the heart: Training increases the heart muscles in size, thickness and strength.
Effects on cardiox repiratory system
Capillaries: improved fitness increases the number of capillaries in your heart muscle and helps your blood vessels more elastic, flexible and efficient
Increased number of red blood cells: these cells carry oxygen to the muscles, so having higher red blodd cell count can improve their performance
Drop In resting blood pressure: regular exercise reduces blood pressure due to the nuscular wall of the veins and arteries becoming more elastic.
Effects on the repiratory system
Increases lung capacity/volume and vital capacity
Increased number of alveoli
Increased strength of the diaphragm and external intercostal muscles.
Adaptation meaning
Your body’s response to training and how your body changes to cope with new activity.
Aerobic meaning
Working at a moderate intensity level with oxygen.
Anaerobic meaning
Working at a high intensity level without oxygen.
Alveoli meaning
Tiny sacs within our lungs that allow oxygen and carbon dioxide to move between the lungs and bloodstream.
Diaphragm meaning
The primary muscle used in the process of inspiration or inhalation.
Cardiac output meaning
The amount of blood ejected from your heart in one minute (CO) = (SV) × (HR)
Resting stroke volume meaning
The amount of blood pumped per beat.
Recovery rate meaning
The speed at which your heart returns To RHR after you exercise.
Extra musculo-skeletal system
Increased strength of ligaments and tendons.
Increased bone density - helps prevent osteoporosis (weakening of bones).
Muscle hypertrophy: is a term for the growth and increase of the size of muscle cells.
Adaptation: the body adapts to training loads imposed on it by increasing the ability to cope with those loads.
