1. Nutritional Aids & Human performance

2. Learning goals
We are learning to identify the pros and cons of various ergogenic aids.
We are learning the types of ergogenic aids athletes use.

3. Ergogenic aids
various substances and techniques by which athletes attempt to improve performance and recovery

4. Nutritional aids and dietary supplements, e. g
Nutritional aids and dietary supplements, e.g., vitamin and mineral supplements, energy drinks, protein supplements, caffeine
Pharmacological aids, e.g., anabolic steroids
Physiological aids, e.g., blood doping
Technological aids, e.g., performance-enhancing fabrics, materials, clothing, and equipment
categories

5. Nutritional Aids Do they work? Can they be regulated?
They claim the product is “natural”, does that make it healthy?
Long term effects of use?

6. products ingested by athletes and other active people in hopes of enhancing performance and recovery
product knowledge is critical
Dietary supplements

7. no scientific proof loading of vitamin/mineral supplements will aid in performance
supplements only beneficial when clear deficiency
healthy, well balanced diet is key
Vitamins & minerals

8. Protein & AA supplements
goal to increase muscle mass, strength and endurance
protein powders, supplements, bars, drinks
contradictory research and conflicting evidence
healthy diet – again…
Protein & AA supplements

9. Protein powders
taken when the goal is to gain muscle mass (2g/kg body weight)
when taken in excess, burned as fuel, stored as fat or excreted during urination
benefit – used as energy
carbs instead!?

10. carnitine advertised as fat burner
made to decrease lactate production, increase VO2 max, delays fatigue, spares glycogen stores and induces loss of body fat
synthesized in kidneys and found in foods: liver, meat, poultry, fish and milk products

11. creatine for athletes that’s require short burst of energy
Creatine is stored in the muscle tissue and any excess creatine is excreted
Creatine has not been tested for safety for teenagers
creatine

12. caffeine stimulates the central nervous system
can increase mental alertness, reduce fatigue and spare glycogen stores
may have an effect on calcium transportation and glycogen breakdown

13. Energy drinks
energy drinks and highly caffeinated “energy shots” are marketed to supply mental and physical stimulation
Health Canada regulates amount of caffeine these beverages contain
most healthy adults can safely consume up to 400 mg of caffeine per day
children under 12 should have less than 85 mg of caffeine per day

15. Guidelines for consumption
children, pregnant women, and breastfeeding women should not consume energy drinks
never drink excessive amounts of energy drinks and never mix them with alcohol
avoid energy drinks when exercising
always drink enough water to stay well hydrated
talk to your doctor before using energy drinks if you are taking medication or other supplements
report any adverse reactions to your doctor or to the Canada Vigilance Program operated by Health Canada
