Q

What happens when tendon is inserted farther away from the joint?

A
  • Should be able to lift heavier weights because of the longer moment arm.
  • Will be a loss in the speed of movement because of the need for more contractions

Q

Muscle doesn’t change its length at all

A

Isometric

21
Q

How does intra-abdominal pressure work when lifting?

A

Deep torso muscles and the diaphragm contract which creates pressure within the abdominal cavity. The pressure supports the vertebral column during resistance training. Weight belts can increase intra-abdominal pressure

22
Q

What reduces risk for injuries while resistance training?

A
  1. warm-up with lighter weights (knee and should prove to be two of the most important joints to warm-up
  2. Don’t ignore pain in or around any joints
  3. Take care when adding in plyometric drills
  4. Exercise within full range of motion
  5. Use light weight when try new exercises or return from extended time off
  6. Never lift max loads without gradually working up to it
23
Q

What does ATP stand for and what is it composed of?

A

Adenosine triphosphate (one adenosine and 3 phosphate groups)

24
Q

What is adenosine made up of?

A

Adenine (nitrogen) and ribose (5 carbon sugar)

25
Q

Breakdown of one ATP molecule for the yield of energy

A

Hydrolysis

26
Q

What are the energy pathways

A
  1. Phosphagen
  2. Glycolysis
  3. Oxidative
27
Q

Short term and high intensity activities present for the beginning of all exercise

A

Phosphagen

28
Q

Used as an energy reserve for rapid replenishment of ATP

A

Creatine

29
Q

Concentrations of products, reactants, or both, within a solution will drive the direction of the reactants

A

Law of mass action

30
Q

Energy system that breaks down carbs

A

Glycolysis

31
Q

What is the end product of glycolysis

A

Pyruvate

32
Q

Pyruvate can be converted into what?

A

lactate or taken to the mitochondria

33
Q

What happens when is pyruvate is converted into lactate?

A

The cori cycle will be used to take the lactate to the liver via blood and convert again to glucose

34
Q

What happens when pyruvate is converted to the mitochondria?

A

Go to the krebs cycle and we concvert to Acetyl-CoA and make NADH.

35
Q

Main source of ATP when at rest or exercising at lower intensities

A

Oxidative

36
Q

This energy system relies on carbs and fats to resynthesize ATP

A

Oxidative

37
Q

0-6 seconds and extremely high intensity

A

Phosphagen

38
Q

6-30 second and very high intensity

A

phosphagen and fast glycolysis

39
Q

30 second-2 minutes and high intensity

A

Fast glycolysis

40
Q

2-3 minutes and moderate intensity

A

Fast glycolysis and oxidative

41
Q

More than 3 minutes and low intensity

A

Oxidative

42
Q

Needed to replenish the levels of oxygen in the blood

A

EPOC (Excess postexercise oxygen consumption)

43
Q

Three types of training?

A
  1. Interval
  2. High intensity Interval
  3. Combination
44
Q

Predetermined exercise and rest intervals

A

Interval training

45
Q

Briefs periods of all out exercise with some intermittent recovery times

A

High intensity interval training

46
Q

Aerobic endurance to anaerobic athlete training for enhanced recovery

A

Combination training

47
Q

What training is the most effective way to improve athletic performance?

A

High intensity interval training

48
Q

What training may result in overtraining?

A

Combination training
