Significance of Body mechanics
Efficient use of the body as a machine, effective functioning, evident in every activity and rest
Concept of body mechanics
The body is typically balanced with correct posture, the wider the base, the better the support. Functioning of the musculoskeletal system.
Guidelines for body mechanics
erect posture, longest and strongest, internal girdle and long midriff, center of gravity closest to the object, slide-roll-push (rather then left), flex knees.
Exercise and Body Movement-Muscle contraction
Isotonic- Muscle shortening, Active movement- walking, free weights
Exercise and Body Movement-Muscle contraction
Isometric- no movement,contraction, no shortening, static conditions- holding
Exercise and Body Movement-Muscle contraction
Isokinetic- muscle contraction with resistance- stationary bike
Effects of Exercise on the body- Cardiovascular
Increase efficiency of the heart, decrease HR and BP, increase blood flow to all body parts, increased circulating fibrinolysin (breaks up small clots)
Effects of Exercise on the body- Respiatory
During exercise, depth of resp, rate, gas exchange, and CO2 excretion are all increased. Regular exercise leads to improved pulmonary functioning.
Effects of Exercise on the body- GI
Increased apetite, intestinal tone increased (improves digestion and elimination), weight control
Effects of Exercise on the body- Urinary
Kidneys work more efficiently, to ore efficiently excrete body wastes
Effects of Exercise on the body- Musculoskeletal
Increased muscle efficiency (strength) and flexibility
Effects of Exercise on the body- Metabolic
Efficient metabolism and body temp. regulation increased.
Effects of Exercise on the body- Integument
overall general health of skin is increased.
Effects of Exercise on the body- Psychological
increased energy, vitality, and general well-being. Improved sleep and appearance (body image)
Positioning :prevention and complications
Fowlers- 45-60 (eating, cardiac, respiratory) Hand edema worsens, pressure ulcers, foot drop
Positioning :prevention and complications
Protective Supine(dorsal recumbent)- face up, surrounded by pillows, foot board
Positioning; prevention and complications
Protective side lying (lateral)- lying on one side, hips and shoulders aligned
Positioning; prevention and complications
Protective Sims- pillow between legs
