title: [EFFECTS OF VOLUNTARY INTAKE OF FLUIDS (WATER AND SPORTS DRINK) IN AMATEUR MOUNTAIN RUNNERS].
abstract: BACKGROUND
  21 K and 1 000 m ascent trail-running races can be dangerous if an appropriate liquid replacement isn't maintained.
  
  
  OBJECTIVE
  know trail-runners level of dehydration and assess the differences between ad libitum water (CcA) and sport drink (CcB) hydration after a trail running race.
  
  
  METHODS
  18 subjects, mean age 31.9 (±2.8) and %MG 10.53 (±2.8), completed CcA or CcB. CcA and CcB effects on Weight (P), Fat Mass (MG), Glucose (GL), Lactate (LT), Systolic (TAS) and Diastolic Arterial Tension (TAD), Heart Rate (PPM) and Tympanic Temperature (Tª) were assessed. All measurements were taken at the start (T1) and the finish (T2) of each race. A Friedman ANOVA test was used to calculate the effect of CcA and CcB on each variable. Differences between race time (TC), % bodyweight loss (%PP) and liquid ingestion (LI) were assessed with a Wilcoxon test. All statistical analysis were conducted with SPSS version 20.0 (IBM, Somers, NY, USA).
  
  
  RESULTS
  mean %PP was 2.967 (± 0.969) and 2.883 (± 0.730) for CcA and CcB respectively. No significant differences were found between %PP and LI (p > .05) between races. Significant changes were found in P, %MG, GL, L, TAS and PPM between T1 and T2 in CcA condition. While only significant changes in P and PPM were stabilised between T1 and T2 in CcB condition.
  
  
  CONCLUSIONS
  neither water or sport drink ingestion avoid trail-runners to reach a dehydrated state. However, dehydration effects seems to be more serious when only water is ingested.
