Question 1

What is muscle fitness?

Answer 1

an integral part of not only health related fitness, but also performance related fitness

Question 2

What is muscle endurance?

ability to perform multiple contractions at a SUB-MAXIMAL load
- more reps means more endurance

Question 3

what is muscle power?

Answer 3

Ability to exert force per unit of time

Question 4

why test muscular fitness?

Answer 4

• it reduces all cause mortality risk beyond what is observed w/ aerobic only Exercise
• provides baseline level of physical fitness
• useful tool for designing exercise training program

Question 5

tests of muscular strength

Answer 5

• can be measured statically (like isometric) or dynamic (like range of motion)
• expressed as resistance overcome (kg or pounds)
• example: static muscle strength test: Handgrip Dynamometer: can predict mortality, and used more in older individuals

Question 6

dynamic muscle strength test

Answer 6

1-RM Testing

• maximal resistance moved through full ROM w/ good posture
• 5-RM and 10-RM tests are also valid for measuring maximal muscle strength

Question 7

when would we use a 5 or 10-RM test as opposed to 1?

Answer 7

for high risk

5 rm would be able to squat or bench heavier loads

Question 8

what is power?

Answer 8

work/time=forcexdisplacement/time
power=forcexdisplacement/time
power=forcexvelocity

Question 9

What is flexibility?

Answer 9

ability to move a joint through a complete, pain free ROM

Question 10

what is balance?

Answer 10

ability to maintain desired position

Question 11

when would you use to assess patients CV endurance and Muscular fitness?

Answer 11

-submax, Astrand rhyming, for cv endurance
-5 rm for his muscular fitness
for high risk: 10 RM (Which is submax)
maybe grip strength for him

Question 12

Astrand rhyming test workload:

Answer 12

Based on gender and whether patient is conditioned or unconditioned
