Descriptive and inferential statistics of the average total ground reaction forces (F tot) and the root mean square accelerations (RMS ISO) that act on the lower back while slalom skiing. Values are reported for two different snow conditions (machine-groomed vs water-injected course), and are based on the data of seven competitive youth alpine skiers (36 slalom turns per athlete and course)
