Q

Myotest

A

triaxial accelerometer

18
Q

Dynamic Strength Testing

A

Tendo or Myotest: force, velocity, and power

19
Q

Relative strength:

A

Relative strength:
1-RM / body mass
Make sure units are the same!

20
Q

Steps for 1-RM Testing

Warm-up sets

A

Warm-up sets
5-10 reps at 40%-60% of estimated 1-RM
3-5 reps at 60%-80% of estimated 1-RM

Attempt 1-RM

2-4 min rest between attempts

Increase weight conservatively
5%-10% upper body
10%-20% lower body

Attempt until failure

21
Q

Spotting Free-Weight Exercises

Primary role:

Exercises requiring spotter:

A

Primary role: protect lifter

Exercises requiring spotter: bar over head or face

Spotter ≥ strength and height of lifter

22
Q

Spotting Free-Weight Exercises

A

Alternating grip to lift and lower bar to lifter
✓Stable base of support and flat back
✓Dumbbells: spot close to the weight
✓Assist liftoff and racking the weight
✓Be vigilant during 1-RM attempts
Spotting Free-Weight Exercises

23
Q

Dynamic Muscular Endurance Testing

A

Repetitions to failure at a given % of body mass or 1-RM

24
Q

Dynamic Isokinetic Muscle Testing

Measures

A

Measure peak torque, total work, and power

Lab/Clinic tool

Note Testing velocities

Isokinetic means constant velocity

25
Q

Dynamic Muscular Endurance Testing

Standardized tests
YMCA bench press

Men

Women

A

Men: 80lbs

Women: 35lbs

26
Q

Battery of Tests why it is not recommended?

A

Because it ends with sit ups and they are awful

27
Q

TWO

The “noninvasive”
Gold Standard

Know I think

A
  • Cybex isokinetic dynamometer
  • Biodex isokinetic dynamometer
28
Q

Dynamic Endurance Tests:

Calisthenics

A
  • Pull-ups
  • Push-ups
  • Trunk curl
29
Q

Assessing Muscular Power Three Test

A

Vertical jump (extensor muscles of leg and back)

Standing long jump

Bosco test (for jumping
athletes)
- endurance too

30
Q

Dynamic Endurance Tests: Calisthenics

Sahrmann Core Stability Test

A

5 Levels

Legs moving while laying down

Moving hip flexors more than core muscles

31

Muscular Fitness Testing: Sources of Error

A

Client

Equipment

Technician

Environment

32
Q

Muscular Fitness Testing: Sources of Error

Client

Equipment

Technician

Environment

A

Client
Practice time
Maximal effort

Equipment
Adjusted to client

Technician
Knowledge
Detect client errors

Environment
Room temperature

33
Q

Assessing Muscle Balance

Contralateral differences

A

“symmetry”
Less than 15%

34
Q

Assessing Muscle Balance

Upper body to lower body ratio must be

A

at least 40% to 60%

35
Q

Muscular Fitness Testing of Older Adults

Above 60

Strength:

Functional Fitness:

Power:

A

Strength:
Submaximal estimate of 1-RM

Functional Fitness:
Arm curl
30-sec chair stand

Power:
Tendo: explosive chair stand

Random test:

Get up and go test

36
Q

Muscular Fitness Testing for Children

Strength:

Endurance:

Power:

A

Strength:
1-RM testing is appropriate
One-on-one supervision
Child-sized resistance machines

Endurance:
Multiple-rep body resistance (e.g., push-ups, pull-ups)

Power:
Standing long jump

37
Q

Resistance Training Programs
Goals – to develop:

A

muscle strength
muscle size (hypertrophy)
endurance
power

38
Q

Table 1.2 do we need to know? On Monday Week 10 Slides

A
39
Q

Types of Resistance Training

A
  • Static (isometric)
  • Dynamic
    Concentric
    Eccentric
  • Isokinetic
40
Q

Static (Isometric) Training

Advantages and Disadvantages

A

Advantages:
Minimal or no equipment
Can be performed anywhere
Can exercise while immobilized

Disadvantages:
Strength gains limited to joint angle trained
BORING!!!!

Recent Finding:
Low-intensity (30-40% 1RM)
isometric training can reduce BP

41
Q

New Finding on Meta Analysis

A

all forms of exercise talked about help lower SBP and DBP

42
Q

Dynamic Resistance Training Variables

A

Intensity (load/resistance)
Sets
Frequency
Volume
Order of exercises
Rest
