1

Why measure musculoskeletal fitness?

- Positively correlated with mobility, independence, glucose homeostasis, bone health and psychological well-being
- Predict overall effectiveness at sport, occupation, or daily functioning
- Prescribe exercise loads in a training program
- monitor progress during training
- Assess the effectiveness of resistance or rehabilitative programs

2

What are the 6 CSEP musculoskeletal tests

3

What is muscle strength

The maximum force that a muscle or muscle group can exert in a single contraction (over a very brief period)

4

What is muscle endurance

The submaximal force that a muscle or muscle group can sustain over a number of repetitions or over an extended period of time

5

What should you consider when assessing muscular strength and endurance

- Joint angle and ROM

7

What type of testing tools are used to measure dynamic muscular strength

What is MVIC

Maximal voluntary isometric contraction

Hand dynomometers measure from _____ to ___ in _____ Increments

0-100 kg in 1kg increments

13

Back and leg dynomometers measure from __ to ___ in ___ increments

14

Do cable tensiometers has a given scale?

no have a variety of scales

15

What are 3 other types of equipment that measure muscular strength

Digital dynamometers, load cells, strain gauges

16

Why is grip strength important

required for many ADL's and movements related to sport and occupational requirements

17

What is grip strength a measure of

Measure of isometric strength and widely used as an indicator of total body strength

18

Grip strength is shown to be predictive of...

functional limitations later in life

19

What is the goal of dynamic strength testing

To determine an individual's maximal force generating capacity (within 1-3 repetitions)

20

What in 1RM

maximum weight that can be lifted for one complete repetition of the movement

21

ACSM recommends ___ and ___ for assessing upper and lower body strength

bench press and leg press

22

What is an alternative for bench and leg press for assessing upper an lower body strength

6-item strength testing batter
upper body: bench press, arm curl, lat pulldown
Lower body: leg press, leg extension, leg curl

23

What are the warm up sets that should be completed prior to completing a 1RM

- 1 set of 5-10 reps at 40-60% of estimated 1RM
- 1-2 sets of 3-5 reps at 60-80% estimated 1RM

24

What are 3 important things to remember when doing a 1RM

- Breathing
- Technique
- Spotting

25

how do you increase weight following a 1RM

conservatively
- 5-10% for upper body exercises
- 10-20% for lower body exercises

26

How much rest should be in between attempts of 1RM

3-5 minutes

27

1RM should be determined within ___-___ maximal efforts

3-5

28

What is your final 1Rm

Weight lifted in the last successful repetition

29

How are maximal strength values most commonly expresseed

in absolute or relative values

30

What is absolute strength

Maximum amount of force measured by a strength test with no adjustment for body mass

31

What is relative strength

- Ratio method of adjustment
- Divide test outcome by body mass

32

There is a strong relationship between 1RM and ____

muscle endurance

33

Can predict __ from muscle endurance tests

1RM

34

how do you predict 1RM from muscle endurance testing

Test the number of repetitions to failure and calculate the corresponding 1RM

35

What do muscle endurance tests measure

The ability of a muscle or muscle group to perform repeated contractions or sustain a contraction over a period of time

36

With muscle endurance testing, you lift _____ until ____

body weight
failure

37

How do you measure static muscle endurance

maintain a specific position for as long as possible

38

What are the two forms of scoring for a push up test

- Max # in 1 minute

39

What is the partial curl-up protocol (including equipment)

- Equipment: mat with 2 pieces of tap and a metronome
