Metabolic equivalents during scooter exercise.

The purpose of this study was to determine the metabolic equivalents (METs) for scooter exercise (riding a scooter, scootering) and to examine the energy expenditure and the heart rate response, so that the results can be used in health promotion activities. Eighteen young adults (10 males and 8 females) participated in scootering on a treadmill at three different speeds for six minutes each. Before, during, and after the exercise, pulmonary ventilation, oxygen uptake (VO(2)), carbon dioxide product, respiratory exchange ratio (R), and heart rate (HR) were measured.

Energy expenditure in maximal jumps on sand.

The purpose of this study was to comparatively investigate the energy expenditure of jumping on sand and on a firm surface. Eight male university volleyball players were recruited in this study and performed 3 sets of 10 repetitive jumps on sand (the S condition), and also on a force platform (the F condition). The subjects jumped every two seconds during a set, and the interval between sets was 20 seconds.

Cardiorespiratory response to dynamic and static leg press exercise in humans.

The purpose of this study is to examine the cardiovascular and metabolic responses between dynamic and static exercise when a leg press exercise is performed. Seven participants (20-21 yrs) were recruited for the experiment. Four modes of dynamic or static leg press exercise were assigned in two combined conditions: a unilateral or a bilateral condition and two exercise intensities with 20% and 40% of maximal voluntary contraction (20% MVC, 40% MVC).

Heart rate response and perceived exertion in college students during riding a scooter.

The purpose of this research is to examine the heart rate responses and the perceived exertion in college students during scootering, and to examine if scootering possibly makes heart rate increase up to the level that can contribute to maintaining or developing cardiorespiratory fitness. Five male students (20-23 yrs) participated in this research, mainly assigned to scooter on an official 400 m-tartan track. Each session of scootering was six minutes.
