Week 4 Flashcards
(38 cards)
Valsava maneuver
Holding breath while exercising until they pass out
Overload principle
Fatigue (irritate) the muscle to create strength
Exercise range for most thex training
7-12 reps
3 sets
Concentric contraction
Shortening of the muscle
Eccentric contraction
Lengthening of the muscle
Types of strengthening exercises
Isometric
Isokinetic
Isotonic
Isotonic
Muscle contracts against a constant load
Strain/stabilize muscle
Isokinetic
Muscle contracts and shorten at constant rate of speed
Machine not commonly used
Isometric
Muscle contracts with no change in muscle length or change in joint movement
Resistance against the muscle
Contraindications for strengthening
Inflammation (muscle/joint)
Pain (severe/or longer then DOMS)
Precautions for strengthening
Substitute motions Osteoporosis DOMS Cardiovascular (valsalva, HTN, MI, CVA) Ab surgery/ab herniation Fatigue Geriatrics
Decreasing DOMS
Light warm up
Stretching (warm muscle)
Gradually increase resistance
Exercise range for endurance
3 sets
30-60 reps
Exp: runners
Muscular endurance
Greater # of contradictions
Mod resistance
High reps
General body endurance
Sustained low intensity exercise
- aerobic
- increase HR, blood flow, O2, RR
Effects of muscular endurance training
Increase vascularization of the capillary beds of the muscle
-better blood/O2 supply
Effects of endurance training on the general body
Decreases Resting HR
Recovery HR more rapid
Guidelines to terminate exercise session
- sever breathlessness
- drop in HR/SBP
- rise in HR/SBP/DBP
- light headed, pallor, cyanosis, ataxia
- loss of muscle control/fatigue
- angina/chest pain/arm/leg
- sever claudation in legs
- ECG abnormality
- failure to monitor equipment
Types of joint mobility
AROM
AAROM
PROM
What happens when we don’t stretch
Constant contraction of the muscles causes sarcomeres to shorten
Define stretching
To lengthen (elongate) pathologically shorten soft tissue structures, thereby increasing ROM
Indications for stretching
- ROM limited (adhesions, contractures, scar tissue)
- decrease motions leads to structural deformity)
- muscle weakness
- part of fitness program
- prior/after exercise (decrease DOMS)
Contraindications for stretching
- bony block/end feel
- recent fracture
- acute inflammation/infection
- sharp acute pain
- hematoma/tissue trauma
- hyper mobility
- down syndrome
- tenodesis
Stretching precautions
- no forcing joint pass normal ROM
- osteoporosis
- new fractures/stabilization
- jts that are immobilized
- progress slowly due to inflammation
- tissue with edema
- over stretching weak muscles
