“…The High group reported greater levels of agreement with the statements "Sport beverages are superior to water in meeting the hydration needs of exercisers" and "Drinking sport beverages with carbohydrates and electrolytes before or during exercise can improve performance for runs of greater than 1 hour compared to water" than did the Low and Mod groups. Experienced endurance athletes drink more sport beverage (even when a least-liked flavor is given) than water during prolonged exercise when both beverages are continuously available 22 and when drinking opportunities are limited. 23 The High group's greater level of agreement with "Drinking sport beverages with carbohydrates and electrolytes before or during exercise can improve performance for runs of greater than 1 hour compared to water" is supported by scientific evidence.…”

Context:The behaviors and beliefs of recreational runners with regard to hydration maintenance are not well elucidated.Objective: To examine which beverages runners choose to drink and why, negative performance and health experiences related to dehydration, and methods used to assess hydration status.Design: Cross-sectional study. Setting: Marathon registration site. Patients or Other Participants: Men (n = 146) and women (n = 130) (age = 38.3 ± 11.3 years) registered for the 2010 Little Rock Half-Marathon or Full Marathon. Intervention(s):A 23-item questionnaire was administered to runners when they picked up their race timing chips.Main Outcome Measure(s): Runners were separated into tertiles (Low, Mod, High) based on z scores derived from training volume, expected performance, and running experience. We used a 100-mm visual analog scale with anchors of 0 (never) and 100 (always). Total sample responses and comparisons between tertile groups for questionnaire items are presented. Results:The High group (58±31) reported greater consumption of sport beverages in exercise environments than the Low (42 ± 35 mm) and Mod (39 ± 32 mm) groups (P < .05) and perceived sport beverages to be superior to water in meeting hydration needs (P < .05) and improving performance during runs greater than 1 hour (P < .05). Seventy percent of runners experienced 1 or more incidents in which they believed dehydration resulted in a major performance decrement, and 45% perceived dehydration to have resulted in adverse health effects. Twenty percent of runners reported monitoring their hydration status. Urine color was the method most often reported (7%), whereas only 2% reported measuring changes in body weight.Conclusions: Greater attention should be paid to informing runners of valid techniques to monitor hydration status and developing an appropriate individualized hydration strategy.Key Words: dehydration, sport beverages, hydration monitoring Key Points• Most runners had experienced performance decrements that they attributed to dehydration. Almost half the runners had sustained heat-related illness symptoms that they related to dehydration.• Despite these adverse events, few participants monitored their hydration levels or used specific hydration plans.• Better dissemination of accurate scientific information about appropriate hydration practices may increase runners' safety.

“…Flavoring beverages at cold temperatures has less effect on consumption (12% increase in consumption compared with water; Hubbard et al, 1984;Szlyk et al, 1989) than flavoring warm beverages (which increased consumption by 38% compared with water; Hubbard et al, 1984;Jung et al, 2007;Szlyk et al, 1989). A benefit of flavoring on consumption has been reported by others (Passe, Horn, & Murray, 2000) and may relate to low concentrations (<0.5 M) of warmer sucrose solutions being perceived as sweeter than similar solutions served at cooler temperatures (Bartoshuk, Rennert, Rodin, & Stevens, 1982;Calvino, 1986). Flavoring and the interaction between temperature, flavoring, and palatability deserve further investigation.…”

Beverage palatability is known to influence fluid consumption during exercise and may positively influence hydration status and help prevent fatigue, heat illness, and decreased performance. Purpose: The aims of this review were to evaluate the effect of beverage temperature on fluid intake during exercise and investigate the influence of beverage temperature on palatability. Methods: Citations from multiple databases were searched from the earliest record to November 2010 using the terms beverage, fluid, or water and palatability, preference, feeding, and drinking behavior and temperature. Included studies (N = 14) needed to use adult (≥18 yr) human participants, have beverage temperatures ≤50 °C, and measure consumption during exercise and/or palatability. Results: All studies reporting palatability (n = 10) indicated that cold (0-10 °C) or cool (10-22 °C) beverages were preferred to warmer ones (control, ≥22 °C). A meta-analysis on studies reporting fluid consumption (n = 5) revealed that participants consumed ~50% (effect size = 1.4, 0.75-2.04, 95% CI) more cold/cool beverages than control during exercise. Subanalysis of studies assessing hydration status (n = 4) with consumption of cool/cold vs. warm beverages demonstrated that dehydration during exercise was reduced by 1.3% of body weight (1.6-0.9%, 95% CI; p < .001). Conclusion: Cool beverage temperatures (<22 °C) significantly increased fluid palatability, fluid consumption, and hydration during exercise vs. control (≥22 °C).

“…This finding agrees with those previously reported by Coombes and Hamilton [29] who suggested that no given commercial sports drink is superior to other sports drinks. The current study was designed so that participants were required to consume identical amounts of drink (P, ISO or CHO) thus the effects of drink palatability [32] and ad libitum consumption could not have been the underlying mechanism for the differences observed. Even though the investigators attempted to mask the type of drink consumed by using a nose clip and opaque drinking bottles, it is possible that participants experienced a 'placebo effect' on performance during the ISO trial.…”

Effectiveness of Commercial versus Homemade Sports Drinks on Fluid Balance and Exercise Capacity during High-intensity Intermittent Exercise

Commercial sports drinks are used widely by athletes involved in high-intensity intermittent (HII) exercise. However, little has been reported on their relative effectiveness compared to simple homemade drink formulations. The purpose of this study was to investigate the effects of different sports drink formulations (commercial v homemade), water and no drink on fluid balance and exercise capacity during HII exercise. Twelve trained men (age: 27 ± 2.1 y) performed a 90-min HII running protocol designed to simulate activity experienced during a football match. The protocol was arranged in six 15-min stages where running speeds ranged between 55% and 120% of VO 2max . The HII protocol included half-time and a run to fatigue post 90 min. Using a single-blind, randomized, cross-over design, participants ingested a preload of 5 ml⋅kg -1 10 min before HII exercise and 3 ml⋅kg -1 every 15 min of either Isostar® (ISO), a homemade sports drink (CHO), placebo (P) or no drink (ND). Blood lactate (Hla), blood glucose (B gluc ), heart rate (HR) and ratings of perceived exertion (RPE) were measured before, during (every 15 min) and after the 90-min HII protocol. Changes in plasma volume were measured at half-time and post 90 min. Sweat rate and fluid balance were calculated post each trial. Time to fatigue (TTF) was recorded at exhaustion. In the ND trial, TTF decreased by approximately 17%, 28% and 43% compared to P, CHO and ISO, respectively (p<0.01) and HR was highest at 90 min following ND trial (p<0.05). TTF was 20% longer in the ISO trial compared to CHO, but this difference was not statistically significant (p>0.05). No differences were noted in HLa, RPE, PV or SR between the trials (p>0.05) but there were significant effects of time (p<0.05). B gluc peaked at 30 minutes in ISO and CHO, but dropped by ~27% in ISO and by ~30% in CHO after half time. Absence of fluid ingestion surprisingly had no significant effect on altering plasma volume or decreasing sweat rate despite causing noticeable decreases in exercise capacity. The homemade drink improved exercise capacity in a similar manner to that of the commercial drink, but neither sports drink achieved superior hydration compared to water. Ingestion of exogenous carbohydrate through sports drink consumption caused an exercise-induced glycemic response when exercise was restarted after half-time. This decline in blood glucose after half-time appears to be marginally attenuated in P trial. A possible suggestion for team sports could be to drink water rather than sports drink prior to half-time period.
