Soc 9 Long Term Effects Of Exercise Flashcards
Effects on the musculo skeletal system
Increased strength of ligaments and tendons
Increased bone density
Muscular Hypertrophy
Adaptation
Effects on the cardio-respiratory system- your heart
Decreased resting heart rate:Heart gets bigger/stronger with training
Faster recovery rate
Increased resting stroke volume
Maxiumum cardiac output
Size and strength of the heart
Effects on the cardio respiratory system- your blood
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 blood cell count can improve their performance.
Drop in resting blood pressure: regular exercise reduces blood pressure due to the muscular wall of the veins and arteries becoming more elastic.
Effects on the respiratory system
Increased lung capacity/ volume and vital capacity
Your lungs will become more efficient, and they will be better at delivering oxygen to your working muscles, so your body will cope better during exercise.
Increased number of alveoli
More alveoli will become available for gaseous, exchange after regular exercise, so more oxygen can be absorbed by the capillaries and more carbon dioxide taken from them.
Increased strength of the diaphragm and external intercostal muscles.
Exercise increases the strength of the diaphragm and the external intercostal muscles – the muscles that work to increase airflow during physical activity.
Adaptation
Your body’s response to training and how your body changes to cope with new activity.
Aerobic
Working at a moderate intensity level with oxygen.
Anaerobic
Working at a high intensity level without oxygen.
Alveoli
Tiny sacs within our lungs that allow oxygen and carbon dioxide to move between the lungs and bloodstream.
Diaphragm
The primary muscle used in the process of inspiration or inhalation
Cardiac output
The amount of blood ejected from your heart in one minute (CO) = (SV) X (HR)
Resting stroke volume
The amount of blood pumped ber beat
Recovery rate
The speed at which your heart returns to RHR ( resting heartrate) after you exercise
Increased lung capacity/volume and vital capacity
Your lungs will become more efficient, and they will be better at delivering oxygen to your working muscles, so your body will cope better during exercise.
Increased number of alveoli
More alveoli will become available for gaseous, exchange after regular exercise, so more oxygen can be absorbed by the capillaries and more carbon dioxide taken from them.
Increased strength of the diaphragm and external intercostal muscles
Exercise increases the strength of the diaphragm and the external intercostal muscles – the muscles that work to increase airflow during physical activity.
