Acute Responses: Dose-Response Flashcards
hedonic theory
human behavior is motivated purely by the pursuit of pleasure and the avoidance of pain
hedonic treadmill
while chasing happiness, people tend to stay at the same level of happiness; keeps going on treadmill
How does the hedonic theory apply to exercise?
- 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
When and how often should we assess affect?
- should be assessed before and after every intensity change
- continuous intensity = assessed at regular intervals
- interval training = more frequent assessments
affective rebound
feeling of “oh I don’t have to do this anymore” - no longer an exercise feeling but a relief feeling
What happens after the ventilatory threshold occurs?
the body begins to expel more carbon dioxide than the oxygen it consumes
What happens after the respiratory compensation point?
HR & VO2 blood lactate rise continuously until exhaustion
What happens during moderate intensity?
- approximately 50-60% VO2 max
- allows maintenance of physiological steady-state
- approximately 80% report stable or increasing pleasure
What happens during heavy intensity?
- 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
What happens during severe intensity?
- from RCP to VO2 max
- inability to maintain or re-establish physiological steady-state
- 95-100% report decreases in pleasure
What are some dose-response core affective responses?
- 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
What are some differences between affective and mood state data?
- 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
