a type or subcategory of physical activity
EXERCISE

referred to as weight-bearing or weight-loading activity; They
produce force on the bones that promotes bone growth and strength.
Bone-stretching activities
Can also be aerobic and muscle-strengthening in nature as they often involve a person’s feet impacting the ground
Bone-stretching activities
BASIC FUNCTIONS OF ENERGY SYSTEMS:
Phosphagen System
Anaerobic glycolysis
Aerobic system
fastest way of acquiring energy for the muscle; short bursts of intense activity such as five-second sprints or jumping are fueled through this energy system.
Phosphagen System
second fastest way of obtaining energy to keep the muscles contracting; does not require oxygen to generate energy
Anaerobic glycolysis
a system needed to generate energy for activities longer than three minutes; requires oxygen
Aerobic system
planned, structured, repetitive bodily movements
that someone engages in for the purpose of
improving or maintaining physical fitness or health
exercise
hiking,skateboarding, brisk walking, etc.
Aerobic activities
most activities in the gym that use weights,
weight machines, etc.
Muscle-strengthening activities
hopping, jumping jacks,skipping, etc.
