San Jose State University looking for female marathoners to participate in a sport nutrition study

Are you a female currently training for a marathon?
Have you ever wondered if you’re eating to optimize your running performance? 
Participate in a sports nutrition study and find out!
We are conducting a graduate research study in sports nutrition and are looking for females at least 18 years of age that have completed at least one previous marathon.
What we want you to do:
  • Email us at womenwhorace26.2@gmail.com and let us know that you would like to participate in our study!
  • We will email you an eligibility determination form which you will complete and return.
  • Eligible participants will be emailed a participation packet that includes:
    • A study consent form
    • Three surveys which will take about 1 hour to complete.
    • Datasheets to maintain a 7-day diet and training log, which will take a total of about 3.5 hours to complete.
What you get out of it:
  • In return for your participation you will receive a dietary intake analysis and a personalized nutrient needs assessment that is created to support your athletic performance.
  • You get to feel good knowing that you are contributing to science.
  • All submitted information will remain confidential.

Coconut water or a sports drink?

 Looks like coconut water and carbo/electrolyte sport drinks didn't reveal a difference with respect to hydration and exercise performance.
Comparison of coconut water and a carbohydrate-electrolyte sport drink on measures of hydration and physical performance in exercise-trained men

Abstract
Background: Sport drinks are ubiquitous within the recreational and competitive fitness and sporting world. Most are manufactured and artificially flavored carbohydrate-electrolyte beverages. Recently, attention has been given to coconut water, a natural alternative to manufactured sport drinks, with initial evidence indicating efficacy with regard to maintaining hydration. We compared coconut water and a carbohydrate-electrolyte sport drink on measures of hydration and physical performance in exercise-trained men.
Methods: Following a 60-minute bout of dehydrating treadmill exercise, 12 exercise-trained men (26.6 ± 5.7 yrs) received bottled water (BW), pure coconut water (VitaCoco®: CW), coconut water from concentrate (CWC), or a carbohydrate-electrolyte sport drink (SD) [a fluid amount based on body mass loss during the dehydrating exercise] on four occasions (separated by at least 5 days) in a random order, single blind (subject and not investigators), cross-over design. Hydration status (body mass, fluid retention, plasma osmolality, urine specific gravity) and performance (treadmill time to exhaustion; assessed after rehydration) were determined during the recovery period. Subjective measures of thirst, bloatedness, refreshed, stomach upset, and tiredness were also determined using a 5-point visual analog scale.
Results: Subjects lost approximately 1.7 kg (~2% of body mass) during the dehydrating exercise and regained this amount in a relatively similar manner following consumption of all conditions. No differences were noted between coconut water (CW or CWC) and SD for any measures of fluid retention (p > 0.05). Regarding exercise performance, no significant difference (p > 0.05) was noted between BW (11.9 ± 5.9 min), CW (12.3 ± 5.8 min), CWC (11.9 ± 6.0 min), and SD (12.8 ± 4.9 min). In general, subjects reported feeling more bloated and experienced greater stomach upset with the CW and CWC conditions.
Conclusion: All tested beverages are capable of promoting rehydration and supporting subsequent exercise. Little difference is noted between the four tested conditions with regard to markers of hydration or exercise
performance in a sample of young, healthy men. Additional study inclusive of a more demanding dehydration
protocol, as well as a time trial test as the measure of exercise performance, may more specifically determine the efficacy of these beverages on enhancing hydration and performance following dehydrating exercise.
