Q

In fitness terms, strength is the ability to exert musculoskeletal force against and external object and it comes from what 4 main sources?

A
  1. How the body is put together as an efficient machine
  2. How the internal systems work to create energy and promote repair, remodeling, and growth in response to training
  3. How skills, attitudes, belief systems, and tolerance to pain interrelate to allow the body to function at peak efficiency
  4. How factors external to the body can be manipulated to produce greater force output

Q

What is limit strength?

A

Absolute strength enhanced by hypnosis, electrotherapy, ergogenic substances(nutritional supplements or drugs), or other techniques. Such aids increase the potential for strength above normal capacity

Q

What is absolute strength?

A

The amount of musculoskeletal force you can generate for one all-out effort. Developed through heavy weight training, typically involving above the 80-85% of maximum effort for each lift

Q

What is speed strength?

A

The ability of the neuromuscular system to produce the greatest possible impulse in the shortest possible time. Defined by Work/Time, where Work is defined as Force x Distance.

16
Q

What is aerobic strength?

A

Musculoskeletal force and energy production that requires oxygen

17
Q

What is general strength?

A

The quality of being physically strong

18
Q

What is specific strength?

A

Limit strength obtained specific to the particular muscle groups that will be most involved in the performance of the events/activities in which are to be performed

19
Q

What is special strength?

A

Specialized type of strength gained that is specific to a particular sport or activity skill/event.

20
Q

What is the strength curve?

A

Graphical representation of how the human body generates and applies force in a specific direction

21
Q

Define force.

A

The interaction that creates work, action, or physical change. Such as a push, pull or lift

22
Q

What is Fmax?

A

Aspect of the strength curve that stands for force max. Fmax divided by Tmax is the definition of explosive strength.

23
Q

What is Tmax?

A

Aspect of the strength curve that stands for time max. Measurement of how long it takes from the beginning of upwards(concentric) movement to exert maximum force.

24
Q

What is the equation for power?

A

P = fd/t

Power is equal to force times the distance per unit of time

25
Q

What is the equation for explosive strength?

A

Explosive strength = Fmax/Tmax

26
Q

What is functional strength?

A

Category of strength that can improve the ability to perform everyday tasks or sports skills, builds overall strength and balance, and augments resistance to injury

27
Q

What is the amortization phase?

A

“Transistion Phase”; represents the brief time between concentric and eccentric movement

28
Q

What is ballistic stress?

A

Commonly used by individuals to help them to develop and improve explosiveness and power in the body. Achieved by accelerating and releasing weight into space

29
Q

What is ballistic movement?

A

Muscle contractions that exhibit maximum velocities and accelerations over a very short period of time

30
Q

What are plyometrics?

A

Exercises in which muscles exert maximum force in short intervals of time, with the goal of increasing both speed and power

31
Q

What is compensatory acceleration training(CAT)?

A

Weight lifting technique used to develop explosive strength whereby you accelerate the bar as leverage improves through the movement
