Exclusion criteria
Exclusion criteria: Current exclusion criteria as of 06/03/2023: 1. Athletes or older adults aged 60+ with a history of any surgery or Achilles tendon's ruptures and/or problems (tendinopathies etc) within a 6-month period prior to trial 2. The main athlete’s event category is not jumping, hurdling, sprinting, or running (intervention group) 3. A score of 0, 1, or 2 in any item in the Lower Extremity Functional Scale (LEFS) (Binkley et al., 1999) during the recruitment process as a safety rule to minimise the risk of injury during the trial. A copy of the LEFS score will be sent to the potential participant by email or post in advance and completed at the beginning of the data collection research day Previous exclusion criteria: 1.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Current primary outcome measures as of 06/03/2023: Measured by a dynamometer at baseline (PRE1), again after 20 min of rest (PRE2) and again after the chiropractic intervention (POST) or rest control (PRE3). 1. Maximum voluntary isometric contraction (MVIC) strength of the plantar flexor muscles 2. Slow accuracy motor skill (AMSS) performance of the plantar flexor muscles 3. Fast accuracy motor coordination skill (AMSF) performance of the plantar flexors muscles Previous primary outcome measures from 20/05/2022 to 06/03/2023: Measured by a dynamometer at baseline (PRE1), again after 20 min of rest (PRE2) and again after the chiropractic intervention (POST): 1. Maximum voluntary isometric contraction (MVIC) strength of the plantar flexor muscles 2. Slow accuracy motor skill (AMSS) performance of the plantar flexor muscles 3. Fast accuracy motor coordination skill (AMSF) performance of the plantar flexors muscles Previous primary outcome measure: Measured by a dynamometer at baseline (PRE1), again after 20 min of rest (PRE2) and again after the chiropractic intervention (POST): 1. Maximum voluntary isometric contraction (MVIC) strength of the plantar flexor muscles 2. Slow (60 s) accuracy motor skill (AMS-60) performance of the plantar flexor muscles 3. Fast (15 s) accuracy motor coordination skill (AMS-15) performance of the plantar flexors muscles | — |
