Resistance Exercise (PTA 102)

loading
A lot of the force generated by an isometric contraction with be ___________ in nature?
TRANSLATORY (HELPS KEEP THE JOINT TOGETHER)
(NO ROTATION)
What is the MVIC?
MAXIMUM AMOUNT OF FORCE WITH ONE CONTRACTION
MVIC
-MAXIMAL VALICINAL ISOMETRIC CONTRACTION
Patients have to exert what percent of the muslces capacity during an isometric contraction?
60-80%
Same length, no change in length in muscle?
ISOMETRIC CONTRACTIONS
What is the only real disagvantage of isokinetics?
CAN ONLY DO CONCENTRIC EXERCISES.
Offers variable resistance?
ISOTONIC RESISTANCE
Offers accommodating resistance?
ISOKINETIC RESISTANCE
What are some precautions associated with eccentric contractions?
-EXCESIVE STRESS ON CARDIOVASCULAR SYSTEM
-DOMS CAN BE MORE SEVERE AND LAST LONGER COMPARED TO CONCENTRIC
Describe eccentric contractions?
-INVOLVE NEGATIVE WORK
-PROVIDE A SOURCE OF SHOCK ABSORPTION
-CAN GENERATE MORE TENSION THAN ISOMETRICS
-CONSUME LESS O2 AND FEWER ENERGY STORES (GLYCOGEN) THEREFORE DEMONSTRATE GREATER RESISTANCE TO FATIGUE
To burn calories you would do __________ contractions, and to build muscle you would do ___________ contractions?
-CONCENTRIC CONTRACTIONS (BECAUSE YOU HAVE TO RECRUIT MORE MOTOR UNITS)

-ECCENTRIC CONTRACTIONS
True/False

A concentric cannot produce as much force and takes more energy?
TRUE
In order to do a concentric contraction you have to recruit what?
MORE MOTOR UNITS
A greater number of motor units are recruited with what kind of contractions?
CONCENTRIC CONTRACTIONS
Concentric contractions generate?
POSITIVE WORK
Eccentric contractions generate?
NEGAGIVE WORK
Contracting muscle is subjected to varying amounts of resistance through the ROM to effectively load the muscle at multiple points in the range?
VARIABLE-RESISTANCE EXERCISE
Describe an isotonic resistance exercise?
-USES A FIXED LOAD
-MAX MUSCLE TENSION ACTUALLY DEVELOPS AT ONLY ONE POINT IN THE ROM.
Isotonic exercises are dynamic exercises meaning?
THERE IS MOVEMENT
What is an example of transfer of training?
SWIMMING WHICH WILL ALSO HELP CARDIOVASCULAR IN RUNNING

-CARRY OVER EFFECTS
What is an example of specificity of training?
A VERY SPECIFIC EXERCISE THAT HAS TO DO WITH THE PATIENTS GOAL.
EX: 6 MILE RUN
Acture muscle soreness?
-OCCURS AS MUSCLE BECOMES FATIGUED DURING ANAEROBIC EXERCISE
-TRANSIENT AND SUBSIDES QUICKLY
Occurs as muscle becomes fatigued during anaerobic exercises?
ACUTE MUSCLE SORENESS
A patient with a RTC tear, it is important to do what kind of contractions?
CONCENTRIC
(ECCENTRIC CONTRACTIONS CAN FURTHER DAMAGE THE MUSCLE)
DOMS is more commonly seen with what kind of exercise?
ECCENTRIC EXERCISES
DOMS
DELAYED ONSET MUSCLE SORENESS
True/False

Glycogen is replaced over several days after a workout?
TRUE
While waiting 3-4 minutes between sets, what happens?
-ENERGY STORES AND O2 ARE REPLENISHED
-LACTIC ACID IS REMOVED
-GLYCOGEN IS REPLACED OVER SEVERAL DAYS
How long should you relax between sets?
3-4 minutes
Characterized by decline in peak torque and soreness in muscle?
MUSCLE FATIGUE
A break down of myelin on the nerves?
POLIO
What will cause muscle fatigue?
A DECREASE OF ENERGY STORES (GLYCOGEN), INSUFFICIENT O2, BUILDUP OF LACTIC ACID.
Patients often want to hold their breath during what kind of exercises?
STATIC EXERCISES (ISOMETRIC)
Epiglottis closses over windpipe and causes BP to go up will result it?
VALSAVA MANEUVER
If someone is holding their breath during exercise what will happen?
VALSAVA MANEUVER
What is power?
AMOUNT OF FORCE YOU CAN PRODUCE IN A PERIOD OF TIME.
What is endurance?
YOUR ABILITY TO MAINTAIN A CERTAIN LEVEL OF FORCE BEFORE IT FATIGUES OUT.
What is strength?
THE MAXIMUM AMOUNT OF TORQUE THAT A PERSON CAN PRODUCE ONE CONTRACTION.
What are the goals of resistance exercises?
-INCREASE STRENGTH
-INCREASE MUSCLE ENDURANCE
-INCREASE POWER
Dynamic
WITH MOVEMENT AKA ISOTONIC
Static?
NO MOTION
(ISOMETRIC CONTRACTION)
Any form or active exercise in which a dynamic or static muscle contraction is resisted by an external force (manually or mechanically)
