Pe component 1 Flashcards
What is flexion
Decrease angle at a joint
bending and arm or leg
What is extension
Increase angle at a joint
the elbow when throwing a shot put
what is abduction
movement away from middle of body
what is adduction
movement toward middle of body
returning arms and legs back to their original position from a jumping jack movement
What is plantar flexion
pointing of toes
Dorsi flexion
pulling toes towards shins
What is rotation
movement around a point
what is circumduction
movement in a circle
Joints for movement
for example joints at the elbow allows the arm to bend and straighten creating movement allowing player to catch the ball
Blood production
plasma / platelets / red and white blood cells
for example if you have a cut during the game white blood cells will help fight off disease and the platelets will form a scab
Muscle attachment
for example muscles in legs contract to pull on a bone causing leg to move allowing them to kick
protection of vital organs
for example allows vital organs to be protected so if they are tackled rib cage will protect the heart and lungs
Mineral storage
both calcium and phosphorus keeps bones strong reducing the risk of bones breaking when a player is tackled hard
long term effect - - increased tidal volume
an increase in tidal volume and vital capacity allows more oxygen to be taken into lungs more co2 to be removed
long term effect - increased number of alveoli - respiratory
more alveoli means that more oxygen can be exchanged between alveoli and capillaries and co2 removed therefore an athlete can work aerobically for longer
long term effect - increased strength of diaphragm and intercostal muscles - respiratory
all adaptations to the respiratory system allow more oxygen can be breathed in and transported to working intercostal muscles
long term effect - increase size of muscles - muscular system
slow and fast twitch will get bigger
long term effect - increased muscular strength - muscular
increase in strength will allow us to produce more force in aerobic activity
long term effect- increased tolerance to lactic acid - muscular
an increase in tolerance to lactic acid allows to muscles to carry on exercising at a high intensity without getting tired
long term effect - increased bone density - skeletal
weight bearing activities lead to stronger bones less chance of injury and osteoporosis
long term effect - increased strength of tendons and ligaments - skeletal
stronger ligaments and tendons means that joints and more stable and less likely to have an injury of tendon
short terms of exercise - respiratory system
tidal volume - amount of air inhaled per breath
minute ventilation- amount of air inhaled and exhaled per minute
frequency - no. of breaths taken per minute
vital capacity - amount of exhaled air after a capacity inhalation = temperature and sweat rate increases
short terms of exercise - muscular system
lactic acid - as muscles temperature and lactate production increase this causes increased fatigue
short terms of exercise - cardio vascular system
-cardiac output - amount of blood pumped out per min
-number of beats per min will increase
-stroke volume increase
-cardiac output will also increase
-as there is a high volumes of blood pumping around blood pressure increase
equations for cardiac output
cardiac output = stroke volume x heart rate
Q= SV x HR
what is plyometric training
a form of interval training using exercises against a resistance
improves muscular endurance
What is weight training
high intensity explosive exercises where the muscles is lengthened and then rapidly shortened
improves muscular strength
what is circuit training
performing a series of station with different exercises a form of interval training with rest between exercises perform each exercises set number of reps and sets.
improves cardiovascular
