VerifiedPhysical fitness is the ability to respond to routine physical demands,with enough reserve energy to cope with a sudden challenge.You can consider yourself physically fit if you meet your daily energy needs,can handle unexpected extra demands,and re protecting yourself against potentialhealth problems,such as heart disease.One component of physical fitness is cardio respiratory fitness,which refers to the ability of the heart to pump blood through the body efficiently.Cardio respiratory fitness is achieved through aerobic exercise-any activity,such as brisk walking or swimming,in which sufficient or excess oxygen is continually supplied to the body.In other words,aerobic exercise involves working out strenuously without pushing to the point of breathlessness.Metabolic fitness is also a component of physical fitness.Metabolic fitness,which is linked to a reduced risk for diabetes and cardiovascular disease,can be achieved through a moderate-intensityexercise program even with little or no improvement in cardiorespiratory fitness.
Summarize the PRICE prescription for coping with an exercise injury.
(76) VerifiedThe PRICE prescription for treating an injury resulting from exercise suggests that you:Protect the area with an elastic wrap,a sling,splint,cane,crutches,or an air cast.Rest to promote tissue healing.Avoid activities that cause pain,swelling,or discomfort.Ice the area immediately (but not directly on the skin),even if you're seeking medical help.Repeat every 2 or 3 hours while you're awake for the first 48 to 72 hours.Cold reduces pain,swelling,and inflammation in injured muscles,joints,and connecting tissues and may slow bleeding if a tear has occurred.Compress the area with an elastic bandage until the swelling stops.Begin wrapping at the end farthest from your heart.Loosen the wrap if the pain increases,the area becomes numb,or swelling is occurring below the wrapped area.Elevate the area above your heart,especially at night.Gravity helps reduces welling by draining excess fluid.After 48 hours,if the swelling is gone,you may apply warmth or gentle heat,which improves the blood flow and speeds healing.
