Ergogenic Aids
simple definition of ergogenic aid
something you believe improves your performance or fitness, other than just standard training
training aids in physiological or fitness context involves the selective targeting of what
- exercise stress
- environmental stress
- nutritional stress
how can ergogenic aids decrease stress (and strain), before, during or after exercise (exercise, environment, nutrition)
exercise : compression garments
environment : supplemental oxygen, cold water immersion
nutrition : sports drinks, energy gels, multivitamins
how can ergogenic aids increase stress (and strain), before, during or after exercise (exercise, environment, nutrition)
exercise : increase force, ankle weights
environment : sauna bathing, altitude training
nutrition : low carbohydrate training
things to consider when deciding on training aids
- remember the purpose of training = to become fitter
- what factors limit fitness
- could your approach have beneficial or harmful effects
- what does research show
- is it relevant / applicable to the person
some environmental stressors are shown to typically enhance endurance fitness (this isnt the case for everyone) what are they
- hypoxia = altitude training for sea level performance
- heat = mixed results but shown to enhance performance
- cold therapy = weight of the evidence is against this
in a sydney study sports drinks enhance …
enhance performance
compression clothing may enhance venous …… and therefore
enhances venous return and therefore cardiac output during exercise
compression clothing may enhance heat….
may enhance heat loss from the body surface
what are customary uses of compression
- lymphoedema
- immobilisation and post surgery
- air travel
what is the rationale of compression clothing
increases venous return and decreased pooling
increased movement efficiency
thermoregulation
compression garments are usually higher where
higher compression peripherally and then lesson compression as you come more proximal to create a pressure gradient to help with the venous return
whats the evidence for compression during exercise
no outstanding evidence
rationale for compression in recovery
- increased muscle metabolic recovery
- decreased muscle damage
