Ely et al. (2012a) [67]

32 M, unacclimated

EX; 50 °C; 3 h work/rest



NaCl + water

No effect

  1. Exercise intensity is described as high (H), vigorous (V) or moderate (M), in accordance with classifications outlined by Norton et al. [86]. Values are Hedges’ g effect sizes
  2. Dh dehydration, EX exercise, OSI overall stability index, Total REC time from completing the dehydration protocol to commencing the subsequent task
  3. hDuring the Loughborough Soccer Passing Test (LSPT), participants completed a random sequence of eight short and long passes of a soccer ball towards a target, as quickly as possible with the fewest time penalties
  4. iThe ‘Ghosting Test’ is a squash-specific movement test. Participants were instructed to collect a half-ball that was placed on three racquets positioned around the court, move to the ‘T’, and then to the next racquet at the opposite corner as quickly as possible
  5. jDuring the In the Loughborough Shooting Test (LSST), participants were required to sprint ~12 m, then pass, control and shoot the ball at targets within the goal area
  6. kThe overall stability index (OSI) is an indicator of a subject’s ability to balance on a platform. A higher OSI indicates poorer balance performance
  7. lMean deflection was defined as the average position of the subject during the balance test. A higher mean deflection indicates more displacement and poorer balance performance
