Q

Cardiorespiratory endurance

A

Ability of heart and lungs to deliver blood and oxygen to working muscles during exercise.

34
Q

Three processes to provide adequate blood and nutrients to the tissues?

A
  • getting oxygen into blood (pulmonary ventilation)
  • delivering oxygen to active tissues from cardiac output.

35
Q

Oxygen carrying capacity is determined by what two principles?

A
  1. ability to adequately ventilate alveoli in the lungs

2. the hemoglobin concentrations in blood.

a protein in red blood cells that is specifically adapted to bond with oxygen molecules.
anemic people

38
Q

A

Delivery of blood to active cells from cardiac output.

39
Q

What is the equation for cardiac output?

A

Cardiac output = HR X SV

40
Q

How do HR and SV increase when exercising?

A

HR increases in linear fashion up to maximal exercise.

SV increases to 40-50% of maximal capacity and then plateaus.

41
Q

The amount of oxygen extracted is a function of what?

Q

Which type of muscle fibers are designed for oxygen extraction?

A

Slow twitch muscle fibers.

43
Q

What is the Endocrine System?

Release Parathyroid hormone

69
Q

Where is the adrenal gland located and what hormones does it release?

A

Located on border of each kidney
Catecholamines
aldosterone
cortisol

70
Q

the pancreas is located where and what hormones does it release?

A

Just below the stomach
insulin
glucagon

71
Q

How does exercise effect catecholamine output?

A

Catecholamine output decreases significantly during the first couple weeks of exercise because of lower resting heart rate and lower rise in blood pressure.

72
Q

How does Exercise impact Cortisol levels?

A

Cortisol levels increase slightly

73
Q

How does exercise impact Insulin?

A

Increased muscle sensitivity to insulin. the normal decrease in insulin in untrained individuals reduces with training.

74
Q

How does exercise impact Glucagon?

A

smaller increase in glucose levels during exercise.

75
Q

How does Exercise impact Growth Hormone?

A

No effect on resting values, and less dramatic rise during exercise.

76
Q

How does Exercise impact Testerone?

A

Resistance training causes more testerone to be released.

77
Q

What are the 3 stages of the general adaption syndrome?

A
  • Shock or alarm phase- cortisol released
  • Adaption or resistance, where body repairs
  • Stage if exhaustion, repairs are made
78
Q

What happens i the Shock phase?

A

Strength gains are contributed to neurommuscular adaptions

79
Q

What happens in the adaption or resistance phase?

A

Progressive increase in muscle size and shape

80
