Safe exercises for pregnant women:
|
o Do not increase HR >140 bpm
o Ab work is ok |
|
What happens to cardiovascular system when pregnant?
|
RHR elevated by 16 bpm
o RCO elevated 40% during 1st trimester, decreases by 3rd o SV decreases in 3rd trimester probably due to venous pooling decreasing venous return |
|
Side effects of pregnancy
|
Constipation
o LBP, greater lordosis o Weight gain o Protruding abdomen, wide gait, center of gravity moves forward |
|
Training effect:
|
Reversibility: two weeks, significant decrease in ex. capacity; 20 days bed rest decreases VO2 max by 25%
o Visibility: varies |
|
Psychological effects of exercise:
|
↓ feeling of anxiety, mod depression, severe depression w/ drug therapy, stress
o ↑ self esteem, sleep behavior |
|
What happens when exercise aerobically?
|
↑ # of capillaries
|
|
Calorie
|
amount of heat necessary to raise one Kgm of water one °C
|
|
Joule
|
unit used to represent energy
|
|
Bomb calorimeter
|
method used to determine heat production by food
o Food oxidized (burned) inside the calorimeter o Amt of heat produced is measured directly and called direct calorimetery |
|
Heat production for food/body:
|
o Fat: 9.4 Kcal/gm // same for body
o Carb: 4.2 Kcal/gm // same for body o Protein: 5.65 Kcal/gm // 4.6 for body b/c bomb oxidizes nitrogen and body does not |
|
Creatine supplement and weight lifting:
|
o Thought to replenish ATP for energy like creatine phosphate
o Subjects taking CP shortly before lifting were able to lift 8% more than those who did not |
|
Effects of SCI:
|
o C4: have scapular elevators and diaphragm; no use of extremities
o C5: some function of biceps, deltoid, scapular adductors; no hand fn o C6: have brachioradialis, wrist extensors, pectoralis major, latissimus dorsi; very functional o T1-5: all UE function; not complete innervation of intercostals and abdominals (respiration) o L1-3: have hip flexion and adduction; full fn for muscles of respiration; usually good temp control |
|
Exercises for SCI
|
o Arm ergometer for aerobic training
o Weight training with hand or wrist weights o Water exercise if pt is safe o Pulmonary fn exercises o Slow deep breathing exercises o w/c push-ups |
|
Why do SCI pts have trouble cooling themselves?
|
o Decreased activity of sympathetic nervous system
|
|
Most common way to get a SCI
|
MVA/traumatic
|
|
Traumatic SCI
|
MVA, fall, GSW, diving accident
|
|
Autonomic hyperreflexia:
|
o SCI above T6
o Higher centers not controlling sympathetic NS and may lose control o Painful stimulus (pt not aware), SNS activated, body cannot stop SNS rxn o Result: nausea, sweating, inc. BP, shivering, headache, etc. |
|
Contracture:
|
o Without PROM, SCIs develop shortened muscles that will lead to permanent bony contractures
|
|
Obesity in children:
|
o Higher morbidity and mortality in adulthood
o Higher risk of respiratory impairments, diabetes, orthopedic impairments |
|
Difference in obesity and over weight:
|
o Over weight: based on height/weight tables; 20% mod and 30% severe
o Obesity: based on % of fat in body; males > 25% bf and females > 30% bf |
|
Info included in food intake diary for obese:
|
o Everything eaten
o How much o Time of day o Where person was o Who with o How person felt before eating |
|
Cause of obesity
|
o Eat too much
o Set point too high or low o genetics |
|
What should exercise prescription for obese include?
|
o Sit to stand
o Sitting for UE o Theraband/free weights: curls, overhead press, shoulder abduction and flexion, hip abduction and flexion o Calorie burning: stairs, park far away, walk |
|
Ways to burn calories in obese:
|
stairs, park far away, walk
|
|
Reasons for obesity
|
hypertension, hypercholesterolemia, diabetes
|
|
Guidelines for nutrition for obese
|
o 10 kcal/lb
o reduce sat fat, use of oils, frying, sugars, fast food o increase dietary fiber, fruits, veggies, lean meat o broil or bake |
|
Complications of diabetes mellitus
|
o Increased risk of amputation
o Heart disease o Stroke |
|
Exercise for people with DM:
|
o Aerobic submax
o Morning b/c it tends to be better for glucose control o Type I: monitor glucose levels at any time during ex |
|
Insulin resistant tissue
|
Type II
o Ex will halp make the tissues less insulin resistant |
