Occurring above a stationary base; movement of the body around its own axis
Movement exercise
Physical activity that is planned, structured and repetitive
Seven basic human body movements
Pull
Push
Squat
Lunge
Hinge
Rotation
Gait
Body mechanics
The ways we move as we go about our daily lives, including how we hold our bodies when we sit, stand, lift, carry, bend, and sleep
Poor body mechanics are often the cause of back problems

Posture
The position in which someone holds their body when standing or sitting
Types of posture
Static posture
Dynamic posture
Static posture
The body and its segments are aligned and maintained in certain positions. Examples include standing, sitting, lying, and kneeling.
Dynamic posture
The body or its segments are moving—walking, running, jumping, throwing, and lifting.
Good posture
The proper alignment of your body when standing or sitting
Importance of having good posture
It allows one to work more efficiently with less fatigue and strain on your body ligaments and muscle
Base of support (BOS)
The area beneath an object or person that includes every point of contact that the object or person makes with the supporting surface
Muscle group
There is no right or wrong way to create a strength training routine. However, pairing certain muscle groups together can help make your workouts more efficient.
Physical fitness
Ability to execute daily activities with optimal performance, endurance, and strength with the management of disease, fatigue, and stress and reduced sedentary behavior

Components of physical fitness
Agility
Balance
Cardiovascular endurance (aerobic power)
Coordination
Flexibility
Muscular endurance
Power/explosive strength (anaerobic power)
Reaction time
Agility
Ability to change position in a shortest period of time
Balance
Ability to maintain their line of gravity within their Base of support (BOS)
Cardiovascular endurance
Ability of the heart and lungs to deliver oxygen to working muscles during continuous physical activity
Coordination
Ability to execute smooth, accurate, controlled motor responses (optimal interaction of muscle function)
Flexibility
Ability of a joint or series of joints to move through an unrestricted, pain free range of motion
Muscular endurance
Ability of a muscle or group of muscles to perform repetitive contractions against a force for an extended period of time
Power
Ability to exert force in the shortest period of time
Reaction time
Ability to respond to a stimulus quickly
Blister
Small pocket of fluid in the upper skin layers, common response to injury or friction
How to cure blister
1. Clean a sharp needle with rubbing alcohol
2. Use the needle to prick the blister in several spots near the edge
3. Let the fluid drain, but leave the overlying skin in place
4. Apply an ointment such as petroleum jelly to the blister and cover it with a nonstick gauze bandage
Tips to cure blister
Cover the blister
Usepadding
Avoidpopping or draining a blister
Keep the areaclean and covered
Muscle soreness
Feeling muscles ache or stiffen for a few days after exercise, known as delayed onset muscle soreness (DOMS)
Muscle soreness can be a deterrent to exercising, but it's temporary and the more you exercise, the less it will occur
Tips to reduce muscle soreness
Warm up
Drinkwater
Limitedrest
Usepropertechnique
Cool down
Staywithinyourlimits
Sprain
Injury to the ligaments and capsule of a joint
Strain
Injury to muscles or tendons
First aid for sprains and strains
1. Use RICEtherapy (Rest, Ice, Compress, Elevate)
2. Rest the injured area
3. Ice the injured area, 20 minutes at a time, 4 to 8 times a day
