CON | TEN | RUP | p Value† | |

Age (years)* | 36.8 (9.9), n = 91 | 40.5 (13.7), n = 70 | 40.7 (11.5), n = 37 | 0.078 |

Height (cm) | 176 (10), n = 95 | 177 (9), n = 66 | 175 (8), n = 37 | 0.623 |

Weight (kg) | 72.0 (12.1), n = 97 | 78.4 (14.1), n = 69 | 85.2 (15.4), n = 37 | <0.001‡ |

BMI (kg/cm^{2}) | 23.3 (2.8), n = 95 | 24.9 (3.4), n = 66 | 27.8 (3.7), n = 37 | <0.001‡ |

Gender (% males) | 67.0, n = 97 | 73.0, n = 74 | 73.0, n = 37 | 0.644 |

Country of birth (% South Africa) | 74.2, n = 97 | 73.2, n = 71 | 78.4, n = 37 | 0.837 |

Gender and country of birth are summarised as a percentage (%), while the remaining variables are expressed as mean (standard deviation). BMI, body mass index.

*The age of the TEN and RUP groups are the age of the onset of the initial symptoms of Achilles tendon injury, which were on average 7.8 (SD 8.0) and 7.5 (SD 8.9) years prior to recruitment in this study respectively.

†p Value = Global, so CON vs TEN vs RUP.

‡Except for the weight difference between the TEN and RUP groups (p = 0.033), all other pairwise differences in weight and BMI were highly significant (p<0.01).
