Abstract
Dehydration has previously been reported to impair both cognition and sports related performance, with most studies conducted in temperate conditions. To our knowledge there have been no studies focusing on the effect of dehydration on golf related performance in warm and humid conditions. The objective of the present study was to investigate the effects of dehydration on golf related performance including hydration status, motor skill, psychomotor and cognitive performance of golfers in a warm and humid environment (29.42 ± 1.59°C, 80.5 ± 5.9% RH). The study used a double blind randomized controlled trial cross-over design and recruited 17 adult male golf players with handicaps <15. Players were randomly allocated into flights and assigned to one of the following trials: i). no fluid (NF) ingestion, ii). Water (W) ingestion, iii). carbohydrate-electrolyte solution (CES) ingestion. For statistical analysis, non-usually distributed data were analysed using Wilcoxon signed-ranked, while the BRUMS was standardised by z-scores. Repeated measures of one-way ANOVA and post-hoc Bonferroni’s multiple-comparison were used to determine effects of dehydration on selected performance measures between the three trials. The findings of the study revealed a significant body mass loss in the NF trial compared to W and CES trials (p = 0.001). Plasma glucose was significantly reduced in NF (p = 0.012), W (p = 0.004) and CES (p = 0.003) following 18 holes of golf. Thirst rating increased significantly after the game of golf in all three trials (p = 0.001) but was significantly higher in the NF trial compared to W (p = 0.019) and CES (p = 0.007). Analysis of heart rate showed a significant increase during the last six holes in the NF trial at tee-off compared to W (p = 0.005) and CES (p = 0.012) and when players were on the green compared to W (p = 0.004) and CES (p = 0.024).
