Objectives: Engaging in dance of various styles confers health benefits among adults; however, additional studies on free-form dancing are needed to quantify its intensity and advance research on dance and health. This study characterized the absolute and relative physical activity (PA) intensities of solo, free-form dancing at self-determined moderate and vigorous intensities in adults.
Method: Participants (N = 48) ages 18 to 83 years old, with 0 to 56 years of dance training experience, engaged in 5-minute free-form dance bouts at respectively self-determined moderate and vigorous intensities, both with and without music. Absolute intensity was measured during bouts using indirect calorimetry (metabolic equivalents; METs = [Formula: see text]O2 ml·kg-1·min-1/3.5). Relative intensity was measured by ratings of perceived exertion (Borg scale) and heart rate. Linear mixed effects models were used to assess the relationship between absolute and relative intensity metrics and model covariates.
Results: On average, the relative intensity of self-determined moderate-to-vigorous intensity dancing, with and without music, was 76% of the age-predicted maximal heart rate; 74% of the heart rate reserve (HRR); and 13 on the Borg scale. By measure of %HRR, all adults reached at least a moderate PA intensity across all dance bouts. The mean absolute intensity of self-determined moderate intensity free-form dancing without music was 5.6 METs, and the presence of music (β = 0.6) and the intention to dance at a vigorous intensity (β = 1.1) were both significantly positively associated with METs, as participants engaged in free-form dance; METs were significantly inversely associated with age (β = -0.05) and BMI (β = -0.10).
Conclusions: When characterized using HRR, engaging in free-form dance at self-determined moderate-to-vigorous PA intensities provided a sufficient stimulus for all adults to reach a moderate PA intensity, which provides evidence that dancing however one wishes at such perceived intensities may support adults in accumulating the recommended weekly dose of 3150 minutes of moderate intensity PA.
