Changes to Physiological Responses Depending on Environment

Question 1

During an Increase in Altitude what Changes Occur to Heart Rate?

Answer 1

Initial: Increases
Acclimatization: Increases

Question 2

During an Increase in Altitude what Changes Occur to Blood Pressure?

Answer 2

Initial: Increases
Acclimatization: Normal

Question 3

During an Increase in Altitude what Changes Occur to Stroke Volume?

Answer 3

Initial: No Change
Acclimatization: Decreases

SV Decreases to balance out increasing HR to normalize CO

Question 4

When coming down from training in high altitude to coming down to sea level what physiological changes occur?

HR/BP/SV/CO

Answer 4

HR and BP Stabilize

Higher CO and Higher SV

Question 5

Cardiovascular Effects to Aquatic Therapy? HR/BP/SV/CO

Answer 5

HR: Decreases
BP: Decrease
“Body is Happy State”

SV: Increases
CO: Increases

Question 6

Respiratory Effects to Aquatic Therapy?

Answer 6

Vital Capacity: Decreases
Work of Breathing: Increases

[Vital capacity decrease, therefore it is harder to take oxygen in, work of breathing must now increase]

Question 7

MSK Effects to Aquatic Therapy?

Answer 7

Weight Bearing: Decreases
Edema: Decreases

Question 8

Effects of Beta-Blockers and HR

Answer 8

Decreases HR and Contractility

• Lowers the myocardial oxygen demand
• Lowers HR during submax and maximal exercise
