Workload And Breathing During Exercise

Workload And Breathing During Exercise


so workload during physical exercise
you’ll often think that you won’t gash you know if you’re breathing through
your nose during intense physical exercise you’re not going to reach a
hundred percent of your capacity because your nose impose the resistance of 50 or
50 percent so they’ve looked at it in studies the benefits of nose breathing
dis in Australian study by the way is that it causes a reduction in the
fraction of expired oxygen if you breathe through your nose during
recreational physical exercise your cells will consume more oxygen the
amount of oxygen delivery to the cells is going to be higher this is probably
because when you breathe through your nose you’ve got higher end tidal co2
with higher end tidal co2 in the lungs in the blood and the tissues the amount
of oxygen that’s delivered to the cells increases so the fraction of expired
oxygen is less meaning – the the amount of oxygen extracted by the longest is
increased while breathing through the nose only all subjects could attain a
work intensity great enough to produce an aerobic effect so on average athletes
will tend to reach 90% of their workload I think that’s pretty good now if you
consider the amount of athletes that every time they go for a run they would
go for a run with their mouths open whereas an actual fact they can attain a
pretty good work rate by nose breathing so you don’t have to run which are might
open to attain a good workplace nose breathing is good this study here was
presented at the Chartered Society of physio turkeys annual Congress in 2009
and it looked at twelve healthy physiotherapy students young people 21
to 27 years of age they were able to attain 85% of their vo2 peak potentially
high training loads so again now you’re these are probably looking at healthy
individuals people would without ask me without chronic obstruction without
chronic obstruction of the nose but again
85 90 percent it’s worth doing it now I would say for you guys who are doing
training do at least some of your runs which are marked closed because it adds
an extra load on body when I was working with the
sprinters in in the United States so they would do for they were doing 200
and 400 meter sprinter and the time of a sprint the time that fatigue comes in is
going to be the last 25 meters so the time to add the extra load here is the
last 25 meters so we had them know his breed I’d stand at about 375 meters this
is 400 meter I had them nose breathe as an are light
sprint and when they seen me at the last 25 meters they had to breathe in breathe
out and hold her breath they had their breath to the last so what I was doing
was pushing them into a hyper coupling hypoxic situation I was pushing them
into a major fatigue to get the body to make adaptations therefore during the
real thing we weren’t going to get to get the same fatigue at the end of the
race does it make sense always when does most fatigue set in you
see two football teams the time of the problems are the last 10 to 15 minutes
that’s when during practice they should be taped up you add an extra load the
last 10 to 15 minutes of practice session so then during the real event
there’s an adaptation after taking place here
