PURPOSE: Snowboarding is a recreational activity with large popularity and is also a sport in the Winter Olympics. Despite its popularity and inclusion in the Olympic program, relatively little remains known about the physiological characteristics of a snowboard session, particularly in field settings. The purpose of this study was to classify physiological responses to recreational snowboarding relative to ACSM daily activity guidelines. METHODS: To date, twenty-one men and women who were experienced snowboarders were recruited from a university community and while snowboarding wore a heart-rate monitor and GPS device. Data were collected at 1-second intervals and analyzed for time spent in moderate and vigorous intensities based on percentage of heart rate maximum (HRMAX) (light ≤ 64% HRMAX; moderate 64–76% HRMAX; vigorous ≥76% HRMAX). Based on this information, the amount of time in each HRZONE was calculated. Data were processed and analyzed using R and SPSS. RESULTS: Participants snowboarded an average duration of ~6 hours, covering ~38 kilometers. Average heart rate over the entire session was 63.3±9.5% of HRMAX (122±19 BPM); during actual snowboarding, average heart rates were ~72% of HRMAX (140±10 BPM). Participants spent a significantly greater amount of time in light and moderate intensity activity during non-snowboarding activity (NS) compared to snowboarding (SN) (p < 0.001 for both),but amount of time in vigorous intensity was not different between conditions (NS: 31.05 ± 35.78 vs SN: 39.36 ± 33.67 minutes, p = 0.478). Total MVPA during SN was 62.33 ± 32.90 minutes compared to 82.86 ± 68.41 minutes for NS, which was not significantly different (p = 0.262). CONCLUSION: The present data suggest that snowboarding can meet ACSM guidelines for moderate-vigorous intensity exercise of at least 30 minutes a day.
