title: Self-selected speeds and metabolic cost of longboard skateboarding.
abstract: OBJECTIVE
  The purpose of this study was to determine self-selected speeds, metabolic rate, and gross metabolic cost during longboard skateboarding.
  
  
  METHODS
  We measured overground speed and metabolic rate while 15 experienced longboarders traveled at their self-selected slow, typical and fast speeds.
  
  
  RESULTS
  Mean longboarding speeds were 3.7, 4.5 and 5.1 m s(-1), during slow, typical and fast trials, respectively. Mean rates of oxygen consumption were 24.1, 29.1 and 37.2 ml kg(-1) min(-1) and mean rates of energy expenditure were 33.5, 41.8 and 52.7 kJ min(-1) at the slow, typical and fast speeds, respectively. At typical speeds, average intensity was ~8.5 METs. There was a significant positive relationship between oxygen consumption and energy expenditure versus speed (R(2) = 0.69 (P < 0.001), and R(2) = 0.78 (P < 0.001), respectively). The gross metabolic cost was ~2.2 J kg(-1) m(-1) at the typical speed, greater than that reported for cycling and ~50% smaller than that of walking.
  
  
  CONCLUSIONS
  These results suggest that longboarding is a novel form of physical activity that elicits vigorous intensity, yet is economical compared to walking.
