the effects of pickle juice for a female recreational marathon runner by annaliese anderson
pickle juice is mostly associated with exercise associated muscle cramps (EAMCs)
what are the theories behind EAMCs?
dehydration theory
electrolyte depletion theory
altered neuromuscular control theory
the effects of pickle juice for a female recreational marathon runner by annaliese anderson
what is the altered neuromuscular control theory?
muscle cramps occur due to a disruption in the balance between excitatory and inhibitory signals within the neuromuscular system. This imbalance leads to an overactive and sustained contraction of the muscle, resulting in cramping.
acetic acid plays a role here…

what is the altered neuromuscular control theory; acetic acid role?
acetic acid can cause a neuromuscular stimulation in the oral cavity which stimulates a reflex that inhibits the firing of alpha motor neurons in the cramping muscle

study on altered neuromuscular control theory
- participants were elicited a flexor hallucis brevis cramp in a dehydrated state.
what was the pickle juice effect?
pickle juice inhibited muscle cramps in hypohydrated humans
so…..
yes, pickle juice did help resolve cramps by 60 seconds faster compared to deionized water. Thus pickle juice does support the altered neuromuscular control theory

study on unacclimatized individuals exercised vigorously iin a hot environment. what were the results on plasma and electrolyte responses to pickle juice?
no difference in electrolyte concentration
the effects of pickle juice for a female recreational marathon runner by annaliese anderson
study on multiple doses, participants over course of 3 days received none or 1 or 2 pickle juice. exercise 30min, rest, exercise again, What were the results ?
no change in osmolarity or volumed

pickle juice cons:
will it drastically change plasma electrolyte imbalance?
no
pickle juice cons
it will help with muscle cramps?
most likely not
pickle juice provide adequate kcal?
no
superstitions, biopsychosocial aspects, routine, and sports ethic will likely have a bigger impact on the runner’s mentality than anything the research says
true

meta analysis have reported that supplementation can improve performance by _________ in various _________-____________ activites
2-3%
high-intensity
efficacy of sodium bicarbonate on athletic performance by brianna
what is the recommended dosage for sodium bicarbonate?
0.3g/kg body mass
efficacy of sodium bicarbonate on athletic performance by brianna
the supplement appears most beneficial during ___________ _______-_________ exercise lasting over 4 minutes (4-10 minutes)
prolonged high-intensity
efficacy of sodium bicarbonate on athletic performance by brianna
what is the ergogenic effect of sodium bicarbonate?
the ergogenic effect appears to work by delaying intracellular acidosis that typically occurs at around 60% of peak power output
efficacy of sodium bicarbonate on athletic performance by brianna
sodium bicarbonate can cause _______ distress
Gi distress
efficacy of sodium bicarbonate on athletic performance by brianna
study by hilton serched for sodium bicrabonate delivery methods to aid or lessen GI distress, what were the results
enteric coated supplement found less gi distress symptoms
efficacy of sodium bicarbonate on athletic performance by brianna
Maurten is a supplement brand, what are their claims on sodium bicarbonate and body’s buffering capacity?
can improve the body’s buffering capacity by increasing blood bicarbonate and blood pH concentrations
efficacy of sodium bicarbonate on athletic performance by brianna
Maurten is a supplement brand, what are their claims on sodium bicarbonate and ability to reduce GI distress?
can reduce GI distress by mixing CHO hydrogel to encapsulate the mini bicarb tablets, making it easier to take higher doses. this method allows to bypass the stomach and for a slower release of bicarbonate in the intestine and lengthen the duration of the bicarb effect

Maurten is a supplement brand, what are their claims on sodium bicarbonate and athletic performace?
designed to help athletes push the boundaries of effort and power during high - intensity exercise
efficacy of sodium bicarbonate on athletic performance by brianna
Maurten conducted their own study on enteric coated sodium bicarbonate on cycling performance, what were their results?
Which coating had fewer GI symptoms?
performance improved by 8.5 sec enteric and 9.6 sec gelatin
Enteric-coated supplement had fewer GI symptoms

Alkaline water for hydration and performance
alkaline water and short term hydration. study by Heil D.Pd acid base balance and hydration status following consumption of mineral-based alkaline bottled water. measured urine and blood output. results?
alkaline water group had significantly …. suggesting…
alkaline water group had significantly lower values in urine output and blood osmolality suggesting greater hydration status and water retention
values returned to pretreatment values after not drining alkaline water
Alkaline water for hydration and performance
study on alkaline water and rehydration. Weidman J Holsworth effect of electrolyzed high pH alkaline water on blood viscosity in healthy adults. results?
exercise can make blood thicker making it harder to circulate due to water loss
AW group viscosity dropped faster and lower therefore better water retention and rehydration making them spend less energy to pump blood
