Heart rate, activity, duration, and affect in added-purpose versus single-purpose jumping activities

Area of Science:

• Occupational therapy
• Exercise physiology
• Human movement science

Background:

• Occupational therapy research often explores the purposefulness of activities.
• Previous studies, like Kircher's (1984), investigated physiological responses to different jumping exercises.

Purpose of the Study:

• To replicate and extend previous research on the physiological and affective responses to rope jumping versus in-place jumping.
• To compare heart rate increase, duration, affective meaning, and preference between the two jumping modalities.

Main Methods:

• Thirty women (18-31 years) participated in a counterbalanced design, performing rope jumping and in-place jumping on separate days.
• Participants ceased activity at a "very hard" perceived exertion level (Borg Scale).
• Physiological data (heart rate) and subjective data (affective meaning via Osgood Semantic Differential, preference) were collected.

Main Results:

• Heart rate increase was significantly higher (p = .01) during rope jumping compared to in-place jumping at equivalent perceived exertion.
• Jumping duration approached significance (p = .06) with differences in the opposite direction of previous findings.
• No significant differences were found in affective meanings or activity preference between the two jumping methods.

Conclusions:

• Rope jumping elicits a greater cardiovascular response than in-place jumping at similar perceived exertion levels.
• Further research is needed to build occupational therapy literature on the purposefulness of various physical activities.
• Findings contribute to understanding the physiological demands of different occupational therapy interventions.
