2. WHICH IS MORE IMPORTANT FOR GOOD HEALTH:
AEROBIC FITNESS OR MUSCULAR STRENGTH?
-BOTH ARE IMPORTANT
-FITNESS BOOM OF 1970’S & 80’S: EMPHASIS ON AEROBIC FITNESS
-TODAY: BOTH CONTRIBUTE TO:
-HEALTH
-FITNESS
-WORK CAPACITY
-OVERALL QUALITY OF LIFE

3. WHAT SHOULD COME FIRST: AEROBIC EXERCISE OR STRENGTH TRAINING?
-GENERAL RULE OF THUMB: AEROBICS PROVIDES A GOOD LEAD INTO STRENGTH TRAINING
-UNLESS EXTREMELY EXHAUSTING: CAN LEAD TO BAD FORM WHEN LIFTING
-BASED ON FITNESS GOALS & PREFERENCES
-PRIMARY GOAL IS STRENGTH DEVELOPMENT: LIFT FIRST
-PRIMARY GOAL IS DEVELOP CARDIORESPIRATORY SYSTEM: HEAVY LOWER BODY
LIFTING WILL MAKE IT DIFFICULT TO SUSTAIN A GOOD CARDIO WORKOUT

4. DO BIG MUSCLES TURN INTO FAT WHEN THE PERSON STOPS TRAINING?
-MUSCLE TISSUE CAN’T TURN INTO FAT TISSUE (OR VICE VERSA)
-MUSCLE & FAT TISSUE ARE COMPLETELY DIFFERENT TYPES OF TISSUE
-MUSCLE TISSUE INCREASES/DECREASES IN SIZE FROM TRAINING/NOT TRAINING
-FAT TISSUE INCREASES/DECREASES IN SIZE FROM GOOD/POOR DIET & WITH/WITHOUT
PHYSICAL ACTIVITY

5. WHAT STRENGTH-TRAINING EXERCISES ARE BEST TO GET A “6-PACK?”?
-NO MIRACLE EXERCISES TO REDUCE BODY FAT AROUND WAIST
-ABDOMINAL EXERCISES WILL STRENGTHEN ABDOMINAL MUSCULATURE BUT WILL NOT BE
SUFFICIENT TO ALLOW MUSCLES TO APPEAR THROUGH FAT LAYER BETWEEN SKIN &
MUSCLES
-WASHBOARD ABS RECIPE:
-MODERATE TO VIGOROUS AEROBIC TRAINING + STRENGTH TRAINING + MODERARE
REDUCTION IN DAILY CALORIC INTAKE

6. STRENGTH TRAINING?
-A PROGRAM DESIGNED TO IMPROVE MUSCULAR STRENGTH &/OR
ENDURANCE THROUGH A SERIES OF PROGRESSIVE TRAINING EXERCISES
THAT OVERLOAD THE MUSCLE SYSTEM & CAUSE PHYSIOLOGICAL
DEVELOPMENT
WHAT ARE SOME OF THE BENEFITS?
1) OPTIMAL PERFORMANCE IN DAILY ACTIVITIES*
*EVERYDAY BEHAVIORS THAT PEOPLE NORMALLY DO TO FUNCTION
IN LIFE (CARRYING A CHILD, CARRYING GROCERIES, SHOVELING SNOW)
2) DECREASES RISK OF DIABETES BY HELPING CONTROL BLOOD SUGAR
3) IMPROVES POSTURE, PERSONAL APPEARANCE, SELF-IMAGE

7. WHAT IS SARCOPENIA?
-AGE-RELATED LOSS OF LEAN BODY MASS, STRENGTH, & FUNCTION
-IN THE OLDER POPULATION STRENGTH MAY BE THE MOST IMPORTANT HEALTH-RELATED
COMPONENT OF PHYSICAL FITNESS
-GOOD STRENGTH CONTRIBUTES MORE TO INDEPENDENT LIVING THAN ANY OTHER FITNESS
COMPONENT
-GOOD STRENGTH ENHANCES OLDER POPULATION QUALITY OF LIFE IN THAT IT:
1) IMPROVES BALANCE & RESTORES MOBILITY
2) MAKES LIFTING & REACHING EASIER
3) DECREASES THE RISK FOR INJURIES & FALLS
4) DECREASES THE RISK FOR OSTEOPOROSIS*
*DISEASE OF THE BONES WHERE BONE MINERAL DENSITY
IS REDUCED LEADING TO AN INCREASED RSIK IN FRACTURE

8. METABOLISM
“ALL ENERGY & MATERIAL TRANSFORMATIONS THAT OCCUR WITHIN LIVING CELLS”
-NECESSARY TO SUSTAIN LIFE
-MUSCLE TISSUE USES MORE ENERGY THAN FATTY TISSUE
-BODY EXPENDS MORE CALORIES TO MAINTAIN MUSCLE THAN MAINTAIN FAT
-ALL OTHER FACTORS EQUAL, 2 PEOPLE THAT WEIGH THE SAME BUT HAVE
DIFFERENT MUSCLE MASS THE ONE WITH MORE MUSCLE MASS WILL HAVE A HIGHER
RESTING METABOLISM

9. DOES METABOLISM SLOW DOWN WITH AGE?
-METABOLISM DOESN’T SLOW DOWN, WE SLOW DOWN
-LEAN BODY MASS DECREASES WITH SEDENTARY LIVING WHICH IN TURN SLOWS
DOWN THE RESTING METABOLISM RATE
-IF PEOPLE CONTINUE EATING AT THE SAME RATE AS THEY AGE BODY FAT WILL
INCREASE
-PARTICIPATING IN A STRENGTH-TRAINING PROGRAM CAN REDUCE EXCESS BODY
FAT
-SMALL INCREASES IN MUSCLE MASS HAVE A LONG-TERM POSITIVE EFFECT ON
METABOLISM

10. WHAT IS THE DIFFERENCE BETWEEN MUSCULAR STRENGTH
& MUSCULAR ENDURANCE?

11. MUSCULAR STRENGTH
-THE ABILITY OF A MUSCLE TO EXERT MAXIMUM FORCE AGAINST
RESISTANCE
-WHAT IS ONE REPITION MAXIMUM (1RM)?
-THE MAXIMUM AMOUNT OF RESISTANCE AN INDIVIDUAL IS ABLE TO
LIFT IN A SINGLE EFFORT

12. MUSCULAR ENDURANCE
-THE ABILITY OF A MUSCLE TO EXERT SUBMAXIMAL FORCE REPEATEDLY OVER TIME
-TYPICALLY DETERMINED BY THE NUMBER OF REPETITIONS AN INDIVIDUAL CAN
PERFORM AGAINST A SUBMAXIMAL RESISTANCE OR BY THE LENGTH OF TIME A
GIVEN ACTION IS SUSTAINED
-STRENGTH & ENDURANCE GO HAND-IN-HAND
-WEAK MUSCLES CANNOT REPEAT AN ACTION SEVERAL TIMES OR SUSTAIN IT

13. WHY DO WOMEN NOT ACHIEVE THE SAME AMOUNT OF MUSCLE SIZE AS MEN?
-THE QUALITY OF MUSCLE IN MEN & WOMEN IS THE SAME, BUT ENDOCRINOLOGICAL
DIFFERENCES DO NOT ALLOW WOMEN TO ACHIEVE THE SAME AMOUNT OF MUSCLE
HYPERTROPHY (SIZE) AS MEN
-MEN ALSO HAVE MORE MUSCLE FIBERS, & BECAUSE OF THE SEX-SPECIFIC MALE
HORMONES, EACH INDIVIDUAL FIBER HAS MORE POTENTIAL FOR HYPERTROPHY
-ON AVERAGE, AFTER 6 MONTHS OF TRAINING, WOMEN CAN ACHIEVE UP TO A 50%
INCREASE IN STRENGTH BUT ONLY A 10% INCREASE IN MUSCLE SIZE

14. “OUCH! WEIGHT ROOM BLUNDERS THAT CAN REALLY HURT”
BY: MICHELLE HAMILTON
WOMEN’S HEALTH

15. 1) A new study found that weight-training injuries among women have jumped by what %?
-63%
2) Working cold, stiff muscles can lead to what?
-SPRAINS & TEARS
3) How does warming up prep your muscles & joints for action?
-INCREASES CIRCULATION & IMPROVES RANGE OF MOTION
4) What type of warm-up can decrease your risk for injury?
-DYNAMIC WARM-UP (STRETCHING WITH MOVEMENT)
-OPINIONS ABOUT STATIC STRETCHING DIFFER
5) When working out, what is the single most important factor in injury prevention?
-PROPER FORM
6) Why are women more at risk for form-related injuries than men?
-NATURALLY WIDER HIPS

16. 7) What does S.E.A.K. stand for?
-Stand straight, Eyes on the horizon, Abs tight, Knees over your second toe
8) Women who lift weights tend to have less-stable what than women who don't lift at all?
-SHOULDER JOINTS (DOING TOO MANY EXERCISES IN WHICH YOUR ELBOWS ARE PULLED BEHIND YOUR BODY CAN
OVERSTRETCH THE CONNECTIVE TISSUE IN FRONT OF THE JOINTS)
9) You shouldn't allow your elbows to extend more than how many inches behind your body?
-2 INCHES
10) What do many women have that can make them more prone to injury?
-STRENGTH IMBALANCES
11) What prevents injuries such as torn ligaments and tendinitis, because your muscles and connective tissues have time to
adapt?
-GRADUAL CONDITIONING
12) What is the three-step progression when starting a workout routine?
1)LEARN TO DO A MOVE USING ONLY YOUR BODY WEIGHT
2)STICK TO ONE SET WITH LIGHT WEIGHTS FOR 2 WEEKS OR UNTIL YOU FEEL COMFORTABLE
3)WHEN YOU CAN COMPLETE NEARLY ALL YOUR REPS WITH PROPER FORM, ADD ANOTHER SET OR MORE WEIGHT
(APPROX. 10% EACH TIME)

17. MYTHS OF WOMEN’S STRENGTH TRAINING
1) ) WEIGHT LIFTING MAKES WOMEN BULKY
-BECAUSE TESTOSTERONE IS RESPONSIBLE FOR A MUSCLE’S BULK, IT IS
IMPOSSIBLE FOR WOMEN TO GAIN HUGE AMOUNTS OF MUSCLE MASS
2) IF YOU STOP WORKING OUT YOUR MUSCLES WILL TURN TO FAT
-MUSCLE & FAT ARE 2 DIFFERENT TYPES OF TISSUE & ONE CANNOT BE
TURNED INTO THE OTHER
-WHEN YOU STOP LIFTING WEIGHTS THE MUSCLE-FAT RATIO CHANGES
3) WOMEN SHOULD CONCENTRATE MORE ON CARDIO
-WOMEN NEED TO LIFT WEIGHTS IN ORDER TO PREVENT LOSS OF MUSCLE
TISSUE
4) WOMEN SHOULD ONLY LIFT LIGHT WEIGHTS
-MUSCLE RESPONDS TO RESISTANCE & IF THE RESISTANCE IS TOO LIGHT
THERE WILL BE NO REASON FOR THE BODY TO CHANGE
-WOMEN LOSE 10% OF THEIR STRENGTH PER DECADE OF LIFE & WEIGHT
TRAINING CAN SLOW THIS

18. FACTORS THAT AFFECT STRENGTH
1) NEURAL STIMULATION
2) TYPE OF MUSCLE FIBER
3) OVERLOAD
4) SPECIFICITY OF TRAINING
5) TRAINING VOLUME
6) PERIODIZATION

19. 1) NEURAL STIMULATION
MOTOR NEURONS
-NERVES CONNECTING THE CENTRAL NERVOUS SYSTEM TO THE
MUSCLE
MOTOR UNIT
-THE COMBINATION OF A MOTOR NEURON & THE MUSCLE FIBERS THE
NEURON STIMULATES TO ACTION
-AS THE # OF FIBERS STIMULATED & FREQUENCY OF STIMULATION
INCREASES, SO DOES THE STRENGTH OF THE MUSCLE
CONTRACTION

21. ELECTRICAL STIMULATION THERAPY

22. 2) TYPES OF MUSCLE FIBER
WHAT ARE THE 2 TYPES OF MUSCLE FIBER?
1)SLOW-TWITCH (RED) FIBERS
1)FAST-TWITCH (WHITE) FIBERS

23. 1) SLOW-TWITCH FIBERS
-MUSCLE FIBERS WITH GREATER AEROBIC POTENTIAL & SLOW SPEED OF
CONTRACTION
-TAKE LONGER TO GET GOING, BUT CAN GO FOR A LONGER PERIOD OF TIME
WITHOUT GETTING TIRED (MARATHONER)
2) FAST-TWITCH FIBERS
-MUSCLE FIBERS WITH GREATER ANAEROBIC POTENTIAL & FAST SPEED OF
CONTRACTION
-FIRE EXTREMELY QUICKLY, BUT GET TIRED EASILY (SPRINTER)
-DURING MUSCULAR CONTRACTION SLOW-TWITCH FIBERS ARE RECRUITED
FIRST
-FAST-TWITCH FIBERS ARE ACTIVATED WHEN THE ACTIVITY IS INTENSE &
POWERFUL
-TRAINING INCREASES THE FUNCTIONAL CAPACITY OF BOTH, BUT…
-THE PROPORTION OF EACH ARE DETERMINED GENETICALLY

24. 3) OVERLOAD
WHAT ARE THE 2 WAYS THAT STRENGTH GAINS ARE
ACHIEVED?
1) THROUGH INCREASED ABILITY OF INDIVIDUAL MUSCLE
FIBERS TO GENERATE A STRONGER CONTRACTION
1) BY RECRUITING A GREATER PROPORTION OF THE
TOTAL AVAILABLE FIBERS FOR EACH CONTRACTION

25. OVERLOAD PRINCIPLE
TRAINING CONCEPT THAT THE DEMANDS PLACED ON A SYSTEM
(CARDIORESPIRATORY OR MUSCULAR) MUST BE INCREASED
PROGRESSIVELY OVER TIME TO CAUSE PHYSIOLOGICAL ADAPTATION
(DEVELOPMENT OR IMPROVEMENT)
-TO INCREASE IN PHYSICAL CAPACITY, MUSCLES HAVE TO BE TAXED
REPEATEDLY BEYOND THEIR ACCUSTOMED LOADS
