Q

What is oxidative stress and free radicals?

A
  • Oxygen in the body splits into single atoms with unpaired electrons. Electrons like to be in pairs, so these atoms, called free radicals, scavenge the body to seek out other electrons so they can become a pair. This causes damage to cells, proteins and DNA

Q

What is an antioxidant?

A

Antioxidants keep free radicals in check. Antioxidants are molecules in cells that prevent free radicals from taking electrons and causing damage. Antioxidants are able to give an electron to a free radical without becoming destabilized themselves, thus stopping the free radical chain reaction

115
Q

What are the general fluid recommendations for men and women?

A
  • We consume ‘fluids ‘via food & beverages
    • 60% of water intake comes from ‘beverage’ sources
    • 40% of water intake comes from ‘food’ sources
  • Many studies conclude we need to consume the following amounts from ‘beverages’ on a daily basis:
    • Males = 12 cups total fluid per day (3 L)
    • Females = 9 cups total fluid per day (2.25 L)
    • (We need to drink 6 bottles per day)
116
Q

What affects fluid loss and hydration?

A
  • Genetics (body size, amount we sweat… different for each)
  • Fitness level (fitter people sweat earlier and > amount)
  • Environment (hot environment = more sweating)
  • Exercise Intensity (intensity up = more sweat = > fluid loss)
117
Q

How much fluid is it common to lose per hour of exercise?

A

It’s common to lose 500mL - 2.0 L of fluid per hour of exercise (sweat)

118
Q

Active people can tolerate drinking 150-300 ml every 15-20 minutes during exercise or competition

122
Q

Studies have shown that after exercise or sport we need how much fluid?

A
  • We tend to only replace 30–70% of sweat & fluid loss
  • We should consume 150% of fluid loss during activity (within 4 hours)
123
Q

Why Don’t We Re-Hydrate Properly?

A
  • We forget (so focused on our training, competition/race/game)
  • Worried about or experiencing stomach upset
  • Lack of beverage availability… doesn’t taste good or is too warm
124
Q

What characteristics should a post-exercise drink have to motivate consumption?

A

Research shows that post-exercise drinks need to be cool, tasty, and available or not enough fluids will be consumed!

125
Q

When is fluid intake enhanced?

A
  • Cool
  • Flavored
  • Contains sodium

This is why ‘sports drinks’, ‘sports waters’ , or ‘vitamin waters’ are an ideal choice immediately before, during, and after exercise

126
Q

How much CHO is in sports drinks?

A

Sports drinks and sports water also contain CHOs (4-8%) that allows for immediate re-fuelling to take place & minerals (lost in sweat)

127
Q

Though plain water is still a suitable option for fluid, what is it missing?

A

it doesn’t stimulate fluid intake or provide CHOs, sodium, or potassium

128
Q

How do you know if you should use ‘sports drinks’?

A
  • Exercise involving very high sweat rates
  • Exercise involving high intensity or long duration
  • Exercise involving hot and/or humid conditions
  • To speed up recovery after exercise
    • Fluid, carbs, sodium, potassium stores replenished
129
Q

What should you look for in a ‘good’ sports drink?

A
  • Non-carbonated water
  • Sodium… prevents muscle cramping
  • Flavor… helps athletes drink more fluids
  • CHOs… sugar improves taste, blood glucose up, helps fuel muscles (30-60 grams of CHO per hour during exercise)
130
Q

What product has become more popular as of late in relation to hydration?

A

Sports water: marketed as Propel, Aquafina Plus, G2, & Vitamin Water

131
Q

  • Has approximately half the kcals of sports drinks
  • Still has added vitamins, & minerals (sodium, potassium)
132
Q

What are key messages related to fluid intake?

A
  • Drink regularly throughout the day leading up to training session or competition (start with water when you wake up!)
  • Start every workout, training session, or competition in a ‘hydrated state’ (urine should be mostly clear)
  • Consume 500-600 ml of fluid within ONE hour before exercise
  • Begin drinking early during exercise and continue with small amounts during… 150-300 ml every 15-20 minutes
  • To account for sweat and urine loss, you should drink 150% of fluid loss in the 4-6 hour window following exercise
133

A
  • Very high concentrations of simple CARBS slows the fluid absorption rates and will hinder re-hydration during due to sweating!
  • High fructose corn-syrup = higher amounts of ‘fat’ created in blood
  • Not a smart strategy to ingest energy drinks before or during exercise… insulin spike and subsequent energy crash!
  • Not suitable after exercise either due to interference of fluid absorption (sports drinks are much better)
  • High concentrations of simple CARBS (fructose) can cause stomach upset and act as a laxative (that’s not good!!!)
144
Q

149
Q

What are some of the other ingredients of concern in energy drinks?

A
  • Pyruvate (a salt of pyruvic acid) claims to fight fatigue and burn fat… ineffective in amounts available in energy drinks
  • Protein & Amino Acids… used sparingly as a muscle fuel and doesn’t not add to glycogen production (no energy!)
  • Creatine, Carnatine, Taurine… amounts added to beverages is too small to be of any benefit to exercise performance
    • Example: you’d have to consume over 170 servings of the beverage to see any benefit from the creatine
  • Lipids… improves taste but fat takes longer to digest and wouldn’t provide ‘quick’ energy before or during exercise
  • Oxygen… some energy drinks add dissolved O2 and claim it accelerates aerobic metabolism, lowers levels of lactic acid, and improves exercise performance… extra ‘oxygen’ consumed in a beverage is ‘exhaled’ (no evidence oxygenized drinks help at all)
  • Hornet’s Saliva (my favorite!!!)… amino acid product found in saliva of baby hornets… claims to decrease lactic acid… absolutely no scientific research to validate this claim!
150
Q

What are the summary suggestions regarding energy drinks?

A
  • People will always be attracted to products that ‘provide more energy’ or ‘give you a boost’
  • Read labels and be cautious… some products can be dangerous - you are only one responsible for what you put into your body
  • Avoid taking ‘herbal additives’ if you are taking prescription medicine… there may be adverse interactions Energy Drinks + Meds, Cold FX, Others? = Risk
  • Avoid any product containing ephedra, yohimbe, and yerba maté… are all unsafe and many times found in ‘energy drinks’!

Informed Sport & Informed Choice: What is the Difference?

A

Informed Sport was developed in 2008 for the elite sports nutrition industry in conjunction with UK Anti-Doping (UKAD). It is the only global third-party testing and certification programme that tests every single batch of a product prior to it being released to market.

Established in 2007, Informed Choice is a global retail monitoring and quality assurance programme that helps reduce the risk of impurities and banned substances entering products. All products bearing the Informed Choice logo or on-pack descriptor allow supplement users to know the product has undergone regular rigorous checks and third party supplement testing.

The key difference between Informed Choice and Informed Sport is the frequency of testing done. Informed Sport certification means every batch/lot of a product is tested before it’s released to market. Informed Choice testing is done through monthly blind sampling.
