Chapter3 Flashcards
any movement that makes the body use energy
physical activity
being able to handle physical work and play each day without getting tired
fitness
planned physical activity done regularly to build or maintain one’s fitness
exercise
the ability of a muscle to repeatedly use force over a period of time
endurance
ability of a muscle to repeatedly use force over a period of time
muscle endurance
the measure of how well your heart and lungs work during moderate-to-vigrous physical activity or exercise
cardio vascular
the ability of your muscle to use force
strength
the ability to move joints fully and easily through a full rang of motion
flexibility
rhythmic moderate-to-vigurous activity that uses large amounts of oxygen and works the heart and lungs
aerobic exercise
anaerobic exercise- intense physical activity that builds muscle but does not use large amounts of oxygen
anaerobic exercise
properties of faty bone, muscle, and fluids that make up body weight
body composition
the framework of bones and other tissues that supports the body
skeletal system
the places were two or more bones meet
joints
a type of connection tissue
tendon
a type of connecting tissue that holds bones to other bones at the joint
ligaments
a strong, flexible tissue that allows joints to move easily, cushions bones, and supports soft tissues
cartilage
tissues that move parts of the body and control the organs
muscular system
the force of blood smashing against the walls of the blood vessels
blood pressure
gentle exercise that gets heart muscles ready for moderate-to-vigours activity
warm up
gentle exercise that lets the body adjust to ending a work out
cool down
the number of days you work out each week
frequency
how much energy you use when you work out
intensity
the number of heart beats per minute that you should aim for during moderate-to-vigours aerobic to help your circulatory system the most
target heart rate
the excessive loss of water from the body
dehydration
substances that cause muscle tissue to develop an an abnormally high rate
anabolic steriods
training to get into shape for physical activity or a sport
conditioning
conditioning to hard or to often without enough rest between sessions
overworking
an injury to the ligament connecting bones at the joint
sprain
a painful inflammation and swelling of a tendon caused by overuse
tendonitis
a major injury that happens when bone is forced from its normal position with a joint
dislocation
a break in a bone
fracture
a small fracture caused by repeated sprain on a bone
stress fracture
the group of organs and tissues that acts as transfer stations carrying needed materials to cells and removing their waste products
circulatory system
blood vessels that carry blood away from the heart to various parts of the body
arteries
blood vessels that carry blood from all parts of the body back to the heart
veins
when blood travels from the heart through the lungs and back to the heart
pulmonary circulation
when oxygen-rich blood travels to all body tissue except the lungs
systemic circulation
