Aerobic strength
34
What is linear strength?
Strength variables that increase or decrease together
35
What is nonlinear strength?
Strength variables that do not directly correlate
36
37
What is the strength curve?
The amount of force produced across a range of motion
38
What is an ascending strength curve?
More force produced at the end of ROM
39
What is a descending strength curve?
More force produced at the beginning of ROM
40
What is a bell shaped strength curve?
More force produced in the middle of ROM
41
42
What is the principle of specificity?
Training adaptations are specific to the stimulus applied
43
How does specificity apply to resistance training?
Exercises should match movement patterns and goals
44
What are general exercises?
Foundational exercises that build overall strength
45
What are isolation exercises?
Single joint movements targeting one muscle
46
What are compound exercises?
Multi joint movements using multiple muscles
47
Why are compound exercises important?
They translate to functional and sport movements
48
What are specific exercises?
Skill based movements that directly improve performance
49
50
What are cross body exercises?
Movements that use diagonal and rotational muscle patterns
51
What is the x factor?
The interaction of muscles during trunk rotation
52
What is the serape effect?
Fascial connections creating cross body force transfer
53
Why are cross body exercises important?
They reflect natural human movement
54
55
What are explosive exercises?
Movements performed with maximum speed and force
56
What are the three phases of explosive movement?
Eccentric amortization and concentric
57
What is the stretch shortening cycle?
Rapid eccentric loading followed by concentric contraction
58
59
What is progressive overload?
Gradually increasing training stress to drive adaptation
60
Which variables can be overloaded?
Load volume intensity frequency density and ROM
61
What is reversibility?
Fitness adaptations are lost when training stops
62
What is tapering?
Planned reduction in training to reduce fatigue and peak performance
63
What must remain high during a taper?
