  1. Notes: n = number of individuals or (for RS scores) number of teams (small numbers of participants failed to attend for some study assessments leading to individual ‘n’ values lower than the number of participants in the study at the time); SD = standard deviation; all P values calculated with (independent group) t-tests except those marked *, where t-tests with Welch’s correction were used due to significantly different standard deviations between study groups; † = positive value for difference indicates Intervention group superior, negative value indicates Control group superior; scores and times rounded to one decimal place, P values rounded to two decimal places, percentages rounded to nearest whole percent.
