Acute Responses: Dose-Response

Question 1

hedonic theory

Answer 1

human behavior is motivated purely by the pursuit of pleasure and the avoidance of pain

Question 2

hedonic treadmill

Answer 2

while chasing happiness, people tend to stay at the same level of happiness; keeps going on treadmill

Question 3

How does the hedonic theory apply to exercise?

Answer 3

• people maximize pleasurable activities and minimize painful activities
• if people find exercise pleasurable = they do it
• if people find exercise painful = they don’t
• if someone enjoys exercise, they are likely to exercise more often

Question 4

When and how often should we assess affect?

Answer 4

• should be assessed before and after every intensity change
• continuous intensity = assessed at regular intervals
• interval training = more frequent assessments

Question 5

affective rebound

Answer 5

feeling of “oh I don’t have to do this anymore” - no longer an exercise feeling but a relief feeling

Question 6

What happens after the ventilatory threshold occurs?

Answer 6

the body begins to expel more carbon dioxide than the oxygen it consumes

Question 7

What happens after the respiratory compensation point?

Answer 7

HR & VO2 blood lactate rise continuously until exhaustion

Question 8

What happens during moderate intensity?

Answer 8

• approximately 50-60% VO2 max
• allows maintenance of physiological steady-state
• approximately 80% report stable or increasing pleasure

Question 9

What happens during heavy intensity?

Answer 9

• approximately 75-85% VO2 max
• possibility of re-establishment of physiological steady state after 15-20 minutes
• some individuals report increases and others decreases in pleasure

Question 10

What happens during severe intensity?

Answer 10

• from RCP to VO2 max
• inability to maintain or re-establish physiological steady-state
• 95-100% report decreases in pleasure

Question 11

What are some dose-response core affective responses?

Answer 11

• exercise below ventilatory threshold/at a self-selected intensity = positive affect
• exercise near ventilatory threshold = pleasant for some/unpleasant for others
• exercise above ventilatory threshold = negative influence on affect for most people

Question 12

What are some differences between affective and mood state data?

Answer 12

• enduring mood state effects likely different intensity relationship from the affective dose-response curves
• in-exercise affect may be useful in predicting future behavior
• mood state effects may be important for particular conditions or specific areas of interest (ex. reducing depression)
• intensity has a greater influence on core affect
