Q

the effects of pickle juice for a female recreational marathon runner by annaliese anderson

what is the altered neuromuscular control theory?

A

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…

Q

the effects of pickle juice for a female recreational marathon runner by annaliese anderson

what is the altered neuromuscular control theory; acetic acid role?

A

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

Q

the effects of pickle juice for a female recreational marathon runner by annaliese anderson

study on altered neuromuscular control theory

  • participants were elicited a flexor hallucis brevis cramp in a dehydrated state.

what was the pickle juice effect?

A

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

Q

efficacy of sodium bicarbonate on athletic performance by brianna

meta analysis have reported that supplementation can improve performance by _________ in various _________-____________ activites

A

2-3%

high-intensity

18
Q

efficacy of sodium bicarbonate on athletic performance by brianna

what is the recommended dosage for sodium bicarbonate?

A

0.3g/kg body mass

19
Q

efficacy of sodium bicarbonate on athletic performance by brianna

the supplement appears most beneficial during ___________ _______-_________ exercise lasting over 4 minutes (4-10 minutes)

A

prolonged high-intensity

20
Q

efficacy of sodium bicarbonate on athletic performance by brianna

what is the ergogenic effect of sodium bicarbonate?

A

the ergogenic effect appears to work by delaying intracellular acidosis that typically occurs at around 60% of peak power output

21
Q

efficacy of sodium bicarbonate on athletic performance by brianna

sodium bicarbonate can cause _______ distress

A

Gi distress

22
Q

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

A

enteric coated supplement found less gi distress symptoms

23
Q

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?

A

can improve the body’s buffering capacity by increasing blood bicarbonate and blood pH concentrations

24
Q

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?

A

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

25
Q

efficacy of sodium bicarbonate on athletic performance by brianna

Maurten is a supplement brand, what are their claims on sodium bicarbonate and athletic performace?

A

designed to help athletes push the boundaries of effort and power during high - intensity exercise

26
Q

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?

A

performance improved by 8.5 sec enteric and 9.6 sec gelatin

Enteric-coated supplement had fewer GI symptoms

27
Q

efficacy of sodium bicarbonate on athletic performance by brianna

Maurten conducted their own study on the effects of CHO hydrogel system for the delivery of bicarbonate tablets on acid-base buffering and GI symptoms in male cyclists. results?

A

maurten bicarb found significantly lower total GI symptoms following supplementation

28
Q

A

high pH 8-9

32
Q

Alkaline water for hydration and performance

how is AW made?

A

pass water through ionizer to split H2O into H and OH. H+ ions are removed or mineral are added to raise pH

33
Q

Alkaline water for hydration and performance

Ergogenic aids

A
  1. increased hydration
  2. reduced oxidative stress
  3. acid-base balance
34
Q

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…

A

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

35
Q

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

A

AW group viscosity dropped faster and lower therefore better water retention and rehydration making them spend less energy to pump blood

36
Q

Alkaline water for hydration and performance

study on alkaline water and performance… improve exercise induced metabolic acidosis and enhance anaerobic exercise performance in conbat sport athletes by chyck

A

significant improvements in mean limb peak power and total work

blood ph increased

37
Q

Alkaline water for hydration and performance

alkaline water and oxidative stress

Lee M fadriquela AW on exercise induced oxidative stress and fatigue in young male healthy adults processes

Aw can effect free radicals

A

AW reduced nitric oxide levels more than pure water

may benefit as an antioxidant

allow athletes to sustain exercise longer and recover faster

38
Q

Alkaline water for hydration and performance

alkaline eater and muscle acidosis

Zajac anaerobic performance and acid base balance in basketball player after consumpton of highly alkaline water

Aw can increase acid base buffering and help in muscle acidosis

A

AW had higher blood pH and bicarb concentrations

longer endurance test results

39
Q

Alkaline water for hydration and performance

Risks

A

GI distress

blood pH imbalance or alkalosis

bitter taste

understudied

kidney disease

PPIs proton pump inhibitor
