Vinyasa yoga involves moving continuously through poses versus holding poses which is present in other forms of yoga. However, the energy cost of Vinyasa yoga has not been well-established.
PURPOSE: This study compared energy expenditure (EE) and heart rate (HR) during acute bouts of Vinyasa yoga and two treadmill walking protocols.
METHODS: Complete data were available for analysis on 28 participants (15 males, 13 females) who performed 60-minute bouts of yoga (YOGA) and treadmill walking, with EE assessed via indirect calorimetry. Treadmill walking consisted of two sessions: 1) participants walked at their self-selected brisk pace (SELF), 2) participants walked at pace that matched their HR to that of their yoga session (HR-Match).
RESULTS: EE was significantly lower in YOGA compared to both the HR-Match (difference=82.2±42.1 kcal; p<0.001) and SELF (difference=44.1±70.0 kcal; p=0.003), and in SELF compared to HR-Match (difference=38.1±75.3 kcal; p=0.012). HR was lower in SELF compared to HR-Match (difference=9.9±13.7 bpm; p=0.001) and YOGA (difference=9.2±14.6 bpm; p=0.003), with no difference between HR-Match and YOGA (0.8±2.9 bpm; p=0.166). RPE was lower in SELF compared to YOGA (difference=2.0±1.6; p<0.001) and HR-Match compared to YOGA (difference=1.0±1.6; p=0.002), but no difference in RPE between HR-Match and SELF (difference=1.0±2.1; p=0.022). Analyses were repeated using only the initial 45 minutes from each of the sessions. Results showed EE was significantly lower in YOGA compared to HR-Match (difference=72.0±37.5 kcal; p<0.001) but not compared to SELF (difference=8.8±53.9 kcal; p=0.393); however, EE was lower in SELF compared to HR-Match (difference= 63.2±60.8 kcal; p<0.001). HR data revealed a significantly lower HR in SELF compared to HR Match (difference=16.6± 13.9 bpm; p<0.001) and YOGA (difference=16.3 ± 14.6 bpm; p<0.001), but no significant difference in the HR between YOGA and HR-Match (difference=0.2±3.7 bpm; p=0.796). Gender did not significantly influence the pattern of the results observed.
CONCLUSIONS: Across a 60-minute period, EE in YOGA is significantly lower than both SELF and HR-Match. When the restorative component of YOGA was removed from the analysis, EE in YOGA was comparable to SELF. Thus, the non-restorative component of YOGA may be a viable alternative to SELF physical activity to achieve physical activity public health guidelines.
