sleep the most powerful performance enhancer

sleep is totally underrated when we are talking about sports performance, and it was not something that started nowadays that sleepless type of behaviour come from a long time ago, by the nineteenth century people were obcessed with performance in the olympic games thus athletes were submitted into a fierce training schedule were they would work out five times a week and have little or zero care about their sleep hygiene, the saying at the time was work when they are sleeping and you should achieve what they are only dreaming! thus this mentality were deeply placed in the whole sports community, this have only changed by early two thousands when neurologists and brain scientists started researching more about the effects of sleep in our brain furthermore in our life and hormones, the results were incredible, sleep not only helped maintain a healthy brain activity such as in mathematical tasks logical problems together with faster reflexes, but also helped memory and muscle skills deeply related to sports training! experts have taken 3 elite athletes and put them into different sleep patterns to see how they would perform, the first slept only 4 hours a night the second 6 and the third 8, as recommended, after just only one night the difference in performance of the three marathonists  were bewildering! the one who slept 4 hour had a forty five percent reduction in his max Vo2 performance with is the capability of the body to absorb and send Co2 waste product out and rapidly absorb O2! the second had a 20 percent reduction in his, and the third had a 10 percent increase in his vo2 max in comparison to the benchmark which was taken a day before! amazing results that only now we are starting to see all types of athletes doing their part to have a regular sleep! after this experiment scientists have continued to do such tests and they have also discovered that not only one night interfere to your aerobic performance but also with your hormones! especially in men who thoroughly need testosterone in order to maintain and grow muscle mass the results of sleep deprivation in hormonal level were shocking as well! man who sleep less than 6 hours have a testo level compared to a man ten years older! furthermore there is also a increased risk in Alzheimer and dementia! in those who do not sleep well! this risk is not solved after a night of good sleep as one may think! scientists have found that our brain does not work like a bank saving sleep to spend another day! each day that you do not sleep well it makes a difference in our health and performance! hence we are seeing even the militaries hire some sleep experts such as Doc Mathew Hoffman to help them increase the performance of their soldiers since they are the ones who have to be ready to combat each and every time! thus experts are trying to solve sleep problems or disrupted sleep schedules using techniques such as naps in determined hours to boost your brain when you know you may have a shorter night! however until the present moment there is no pill no counter side effect to sleep deprivation! the effects still happen even if you have a 6 hour sleep and a 2 hour nap during the afternoon the side effects still happen! thus is crucial that we try to maintain a sleep hygiene at the best that we can! experts have some tips when you are trying to sleep! a colder room will always be better than a hotter one! our body need at least a 2 degree Celsius reduction in our average temp to start sleep procedure! moreover they recommend a regular sleep patern which means if you go to sleep 10 pm try as best as you can to sleep everyday at 10 pm and wake up 7 am! your body syncs your internal body clock!thus you will be always sleepy at the same time! and work out! is paramount for you to exercise and move your muscles to burn some calories and improve your hormonal levels! by following those tips you should see a real improvement in your sleep as well as your life!! sleep is the best!

Resposta: 2,4 · [tex]10^{12}[/tex] N

Explicação: Usando a fórmula da força elétrica que indica as duas cargas em análise, sobre a distância entre elas ao quadrado, multiplicando pela constante eletrostática.

Força elétrica = K · q1 · q2 / d²

K = 9·[tex]10^{9}[/tex]

A distância deve ser convertida para metros.

Força elétrica = (9 * 10^9) * (1,6 * 2,4)/(0,12)^2

Força  elétrica = (9 * 10^9) * (3,84)/(0,0144)

Força  elétrica = (34,56 * 10^9)/(0,0144)

Força  elétrica = (2400 * 10^9)

Força  elétrica = 2,4*10^12N
