A Descriptive Exploration of Heart Rate Response to Live Professional Irish Dance Performance

Area of Science:

• Sports Science
• Physiology
• Performing Arts Medicine

Background:

• Limited data exist on the physiological demands of live dance performances, especially across diverse genres.
• Previous studies often rely on simulated conditions or rehearsals, not real-time audience performances.
• Understanding the specific demands of Irish dance is crucial for dancer health and training.

Purpose of the Study:

• To quantify the physiological demands of live professional Irish dance performance.
• To describe exercise intensity, work-rest cycles, and heart rate responses during a live show.
• To investigate variations in physiological load based on dancer role (troupe vs. lead) and sex.

Main Methods:

• Descriptive, cross-sectional study involving 24 professional Irish dancers from Riverdance.
• Heart rate monitors recorded data every 5 seconds during live matinee and evening performances.
• Video analysis was used to determine time spent in work and rest intervals.

Main Results:

• Dancers performed at hard to very hard intensities (mean >72% HRmax) for approximately 3-minute intervals.
• Significant variation in overall physiological demand was observed, influenced by role-specific on-stage time and intensity.
• Mean on-stage times varied by role, with male leads performing the longest durations.

Conclusions:

• Individual Irish dance numbers are short, high-intensity bouts.
• The overall physiological burden varies greatly among dancers due to role-dependent performance durations and recovery practices.
• Future research should incorporate individual roles and full show duration for accurate physiological demand assessment.
