Ex Testing Test 1 (quiz 3)

which of the following best describes muscular STRENGTH

• rate at which mechanical work is performed

• peak force or torque developed during an MVC

• ability to exert sub-maximal force repeatedly, or sustain a static contraction without fatigue

• maximal amount of force one can exert in the least amount of time (force/time)

Answer explanation

rate at which mechanical work is performed = POWER

-maximal amount of force one can exert in the least amount of time (force/time) = ALSO POWER

ability to exert sub-maximal force repeatedly, or sustain a static contraction without fatigue = ENDURANCE

why is grip strength the main measure of strength in the CSEP PATH

• it is strongly correlated with body strength

• good for measuring overall strength for health outcomes

• it doesn't require any specific equipment

• good for determining upper and lower body strength

T or F: MSK tests are the hardest to standardize but more helpful for designing prescriptions b/c they're specific

• T

• F

what does each letter in SMART stand for

what are the benefits of a 1-RM test

Answer explanation

1) very specific to a target muscle group

2) easy to control variables like ROM, speed, type of contraction - e.g. biodex

3) can provide health status - muscle strength is correlated with ADLs

- can determine strength threshold (amount of force needed for ADLs)

4) can determine appropriate workloads for exercise prescriptions

what are the limitations of a 1-RM test

Answer explanation

- injury, puts joints at risk

- technique, have to have extensive knowledge about proper form to safely observe a client

- economy, extremely taxing, need equipment that can test at different levels of strength

which of the following tests are not suitable for someone with osteoporosis

• push-ups

• sit and reach

• vertical jump

• forearm plank

• one leg stance

detraining timeline:

metabolic changes: __-__ weeks at level of muscle tissue

vo2 max: __ weeks in trained people, __ in untrained people

MSK: __ weeks

why does it take longer to see detraining in MSK strength

Answer explanation

- it is a neurological change not a muscular change

- created a motor program in your brain to create a large force of contraction, hard to get rid of

describe the overload principle

Answer explanation

-right after a training session, there is a period where capacity decreases

- the body adapts to build capacity back stronger, this is where you introduce a training stimulus that is greater than the previous one

- challenges the system at an increased intensity, frequency, duration, etc
