Muscle Strength
|
Ability of contractile tissue to produce tension and a resultant force based on the demands placed on the muscle.
|
|
Strength training –
|
systematic procedure of a muscle of muscle group lifting, lowering, or controlling heavy loads for a relatively low number of repetitions or over a short period of time
|
|
Muscle Power –
|
defined as work produced by a muscle per unit of time (force x distance/ time)
|
|
Power training –
|
power can be enhance by either increasing the work a muscle must perform during a specified time or by reducing the amount of time required to produce a given force
|
|
Endurance –
|
ability to perform low-intensity, repetitive, or sustained activities over a prolonged period of time
|
|
Endurance training –
|
characterized by having a muscle contract and lift or lower a light load for many repetitions or sustain a muscle contraction for an extended period of time
|
|
Overload prinicple
|
Muscles must be challenged to perform at a greater level that to which it is accustomed in order for performance to increase
Focuses on progressively loading a muscle In strength training, amount of resistance is increased In endurance training, the time of contraction or the number of repetitions must be increased |
|
What does SAID stand for?
|
Specific adaptation to imposed demands
|
|
SAID
|
Extension of Wolff’s law – body systems adapt over time to the stresses placed on them
|
|
Specificity of training
|
Whenever possible, exercise incorporated in a program should mimic the anticipated function
|
|
Transfer of training
|
Reported to occur on a very limited basis
|
|
Reversibility principle
|
Changes made through strength/endurance training are short-lived unless training-induced changes are used regularly for functional activities or unless individuals participate in a maintenance program of resistance exercise
Detraining begins within a week or two after stopping a resistance exercise program If you don’t use it, you lose it!!!! |
|
Derminants of a Resistance Exercise Program
|
Alignment
Stabilization Intensity Volume Exercise order Frequency Rest interval Duration Mode of exercise Velocity of exercise Periodization Integration of exercises into functional activities |
|
Alignment
|
segements of the body during exercise
|
|
Stabilization
|
Prevent subsitution
|
|
Intensity
|
Level of resistance
|
|
Volume
|
repititions and sets multiplied by resistance used
|
|
Exercise order
|
Large muscle groups before small muscle groups
Multi-joint before single-joint muscles Higher intensity exercises before lower intensity exercises |
|
Frequency
|
How often you exercise
|
|
Rest interval
|
time between sets to allow body to recuperate
The higher the intensity the longer the rest |
|
Duration
|
total time frame (weeks, months)
|
|
Mode of exercise
|
type of exercise, muscle contraction, position of pt, etc
|
|
Velocity
|
how quick a muscle fires
|
|
Periodization
|
Variation of intensity and volume during specific periods of resistance training
Prevents overtraining and mental staleness; more high level |
|
Integration into functional activities
|
use of resistance exercises that approximate or replicate functional demands
|
|
Valsalva maneuver
|
Defined as an expiratory effort against a closed glottis
Increases intra-abdominal and intra-thoracic pressure, which in turn forces blood from the heart, causing and abrupt temporary increase in arterial pressure Make sure this is avoided when pt’s are exercising |
|
Precautions for Resistance Exercise
|
Valsalva maneuver
Substitute motions Exercise-induced muscle soreness Overtraining Overwork pathological fx |
|
Exercise-induced muscle soreness
|
Acute
DOMS – 12 – 24 hours after exercise; tenderness to palpation; local edema and warmth; stiffness |
|
Overtraining
|
A decline in physical performance in healthy individuals participating in high-intensity, high-volume strength and endurance training programs
|
|
Overwork
|
Progressive deterioration of strength in muscles already weakened by nonprogressive neuromuscular diseases
|
|
Valsalva maneuver
|
Defined as an expiratory effort against a closed glottis
Increases intra-abdominal and intra-thoracic pressure, which in turn forces blood from the heart, causing and abrupt temporary increase in arterial pressure Make sure this is avoided when pt’s are exercising |
|
Precautions for Resistance Exercise
|
Valsalva maneuver
Substitute motions Exercise-induced muscle soreness Overtraining Overwork pathological fx |
|
Exercise-induced muscle soreness
|
Acute-during or directly ater stenuous exercise performed to the point of muscle exhaustion.
DOMS(delayed onset muscle sorness) – 12 – 24 hours after exercise; tenderness to palpation; local edema and warmth; stiffness |
|
Overtraining
|
A decline in physical performance in healthy individuals participating in high-intensity, high-volume strength and endurance training programs
Brought on by inadequate rest intervals between exercise sessions, too rapid progression of exercises, and inadequate diet and fluid intake |
|
Overwork
|
Progressive deterioration of strength in muscles already weakened by nonprogressive neuromuscular diseases
|
|
Pathological fracture
|
Fracture resulting from minor stress in an already weakened bone (i.e. pt’s with osteoporosis)
|
|
Contraindications
|
Pain
If pain is present with any type of resistance exercise, stop that exercise!! Inflammation Absolutely contraindicated in inflammatory neuromuscular disease Dynamic resistance exercise contraindicated in acute inflammation of a joint; gentle static exercises are permitted Severe cardiopulmonary disease Wait up to 12 weeks after heart attack or bypass surgery Pt must be cleared by physician |
|
Progressive resistance exercise (PRE)
|
Delorme
Oxford DAPRE |
|
Circuit weight training
|
Pre-established sequence (circuit) of continuous exercise performed in succession at individual exercise stations that target a variety of major muscle groups
|
|
Plyometric training
|
A system of high-velocity resistance training characterized by a rapid eccentric contraction during which the muscle elongates, immediately followed by a rapid reversal of movement with a resisted shortening contraction of the same muscle
|
|
Resistance Exercise
|
any form of active exercise in which dynamic or static muscle contraction is resisted by an outside force applied manually or mechanically.
