Q

How does the hedonic theory apply to exercise?

A
  • 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

Q

When and how often should we assess affect?

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

Q

What happens during moderate intensity?

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

Q

What happens during heavy intensity?

A
  • 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

Q

What happens during severe intensity?

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

Q

What are some dose-response core affective responses?

A
  • 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

Q

What are some differences between affective and mood state data?

A
  • 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
