we all know the importance of nutrition
0:02
for supporting our performance and our
0:03
recovery and therefore how we achieve
0:05
our fitness related goals but with so
0:07
much nutrition advice circulating social
0:09
media it can be easy to get confused
0:11
with what nutrition advice to follow
0:15
my name is Elle specialist eating
0:17
disorder and sports dietitian and I'm
0:19
going to break down the purpose of
0:21
pre-intra and post-workout feeling let's
0:23
start by taking a look at pre-workout
0:25
the purpose of pre-workout fueling is to
0:27
ensure that your body is prepared for
0:29
the workout ahead the importance of
0:31
pre-workout nutrition will depend on
0:33
your goals are you training for
0:35
performance or is this Leisure the
0:37
requirements of your spores for example
0:39
is it power or endurance based the
0:42
intensity this will dictate Which
0:44
substrate will be the predominant fuel
0:45
provider the duration this will
0:47
influence how much energy you need the
0:49
timing of the day is your pre-workout
0:51
meal the first meal you've eaten or have
0:53
you been eating regularly throughout the
0:54
day in the lead up to the session your
0:56
digestion and preferences you should be
0:58
doing what works for you and of course
0:59
your overall energy requirements and
1:01
intake in many sports especially high
1:04
intensity ones carbohydrates are the
1:06
preferred fuel source we can store
1:08
carbohydrates in the form of glycogen in
1:10
our muscles and our liver glycogen is
1:12
converted back to glucose us and is drip
1:14
fed into the bloodstream in the absence
1:16
of food when glycogen stores are at full
1:18
capacity they can normally provide us
1:20
with energy for up to 24 hours however
1:22
the rate at which we use glycogen is
1:25
much higher when we are exercising and
1:27
glycogen can be used up pretty quickly
1:29
throughout some sports especially high
1:31
intensity ones and this is why it is
1:33
important to ensure that these stores
1:34
are topped up before we go into a
1:36
training session when it comes to
1:38
pre-workout nutrition the timing of a
1:40
meal is really important to consider if
1:42
you are eating two to three hours prior
1:44
to recession the meals should be high in
1:46
carbohydrates preferably starchy
1:48
carbohydrates to provide longer lasting
1:51
energy it should also contain a source
1:52
of protein to support your overall daily
1:54
requirements and ideally be low in fat
1:57
and fiber to prevent digestive issues if
1:59
you are eating 30 to 60 minutes prior to
2:01
training the meals should be rich in
2:03
carbohydrates but preferably simple
2:04
carbohydrates for fast acting energy it
2:07
should also contain minimal amounts of
2:09
fat as this slows down the digestion and
2:11
the release of energy and ideally it
2:12
should be low in 5 to prevent digestive
2:14
issues now protein is the one
2:16
macronutrient that we cannot store in
2:18
our body which is why it is important to
2:20
spread our intake out across the day
2:22
considering that the purpose of
2:23
pre-workout fueling is to provide energy
2:25
the importance of protein in this meal
2:27
can depend on a few factors protein can
2:29
take longer to digest and slow to
2:31
provide energy but you may choose to
2:33
include some protein with your
2:34
pre-workout meal in order to support
2:36
your overall daily protein requirements
2:38
some research has actually shown that
2:40
the ingestion of protein prior to a
2:42
workout can increase the amount of amino
2:44
acids in the amino acid pool which may
2:46
improve muscle protein repair my protein
2:48
has some snacks which can be useful for
2:50
pre-workout fueling like protein
2:51
Flapjacks and oat bakes caffeine is also
2:54
something that may be considered as part
2:56
of your pre-workout regime to experience
2:58
the benefits of caffeine such as
2:59
improved alertness it is recommended to
3:01
take between three to six milligrams per
3:04
kilo of body weight at least 30 minutes
3:06
prior to your session this would look
3:08
like 210 to 420 milligrams for an
3:11
individual who weighs approximately 70
3:12
kilos and you can get this from a scoop
3:14
of my protein pre-workout or a strong
3:16
coffee everyone responds differently to
3:18
caffeine so the timing and dosages will
3:20
differ among individuals remember your
3:23
pre-workout meal is a small window
3:24
within the day and your overall energy
3:26
intake is important not feeling
3:28
adequately prior to a session can lead
3:30
to fatigue and quicker and feeling
3:31
weaker which can impact our performance
3:33
and our progression coming into sessions
3:35
fasted can be counterproductive for this
3:38
reason especially if your goal is to
3:39
improve your performance or strength
3:41
next up intro workouts the purpose of
3:44
intra-workout feeling is to provide an
3:46
additional source of energy so that
3:48
performance can be sustained in some
3:50
cases inter-workout nutrition can be
3:51
essential in other cases it may be
3:54
beneficial and in some it's just not
3:55
necessary at all ensure workout
3:57
nutrition may be required when sessions
3:59
or events last longer than 90 minutes or
4:01
60 minutes if they're at a high
4:02
intensity if you haven't had adequate
4:04
feeling before a training session if
4:06
you're training twice in a day or having
4:08
sessions close together as this makes it
4:10
harder to ensure glycogen stores are
4:12
primed again for the next session or if
4:14
you are participating in multi-day
4:15
events where again the time for glycogen
4:18
resynthesis is limited ensure workout
4:20
nutrition is similar to pre-workout
4:22
nutrition except the emphasis is really
4:24
on the consumption of carbohydrates in
4:26
order to provide fast acting energy
4:27
digestion is also an important factor to
4:30
consider with inter-workout nutrition as
4:32
changes in our digestion is common with
4:34
exercise examples of suitable
4:36
intra-workout Foods include dried fruit
4:38
like dates or raisins fruit toast and
4:40
rice cakes and honey sports drinks and
4:42
energy gels can also be useful or you
4:44
could add carbohydrate to your drink
4:46
throughout the session by using my
4:47
protein dextrose glucose carb mix and
4:50
finally post-workout the purpose of
4:52
post-workout nutrition is to enhance the
4:54
recovery process exercise is a stress on
4:57
the body especially if it's intense so
4:59
it's important to support recovery
5:00
through nutrition and hydration what you
5:02
do in the hours following one session
5:03
can really play a crucial role in how
5:05
you perform in subsequent sessions and
5:07
this applies to both recreational gym
5:09
goers and athletes I often advise that
5:12
there are four r's to remember member
5:13
when it comes to recovery number one
5:15
repair our body is in a constant state
5:18
of muscle protein breakdown and repair
5:20
but the rate of this is elevated after
5:22
exercise in order to promote muscle
5:24
protein synthesis AKA repair and growth
5:27
a certain amount of amino acids from
5:31
quantity of protein consumed is not only
5:33
important for recovery but also the
5:35
quality a specific amino acids play
5:37
important roles in muscle growth and
5:39
recovery for example three to four grams
5:41
of leucine is required to stimulate
5:43
muscle protein synthesis this is usually
5:45
easily obtained through animal protein
5:47
sources such as whey protein milk yogurt
5:50
and chicken a multitude of studies
5:51
suggests that approximately 20 to 40
5:53
grams of protein is a sufficient amount
5:55
to maximally stimulate muscle protein
5:58
synthesis post-workout this looks like
6:00
one to two scoops of my protein impact
6:02
way which provides 20 grams of high
6:04
quality protein per scoop number two
6:06
replenish during exercise muscle
6:09
glycogen stores become depleted and the
6:11
body's ability to resid the size
6:13
glycogen is at its peak during the
6:15
initial few hours following exercise but
6:17
this can continue over a longer period
6:19
it is important to consume carbohydrates
6:21
within this post-workout window to
6:23
replenish the stores in order to prevent
6:24
fatigue and promote recovery number
6:26
three rehydrate depending on how much we
6:29
sweat there is a loss of both fluid and
6:31
electrolytes during training and it's
6:33
important to rehydrate after to prevent
6:35
electrolyte imbalances and number four
6:38
re-nourish exercise can cause increased
6:41
levels of oxidative stress which
6:42
produces free radicals which can cause
6:44
inflammation and play a role in impaired
6:46
muscle repair and thus performance
6:49
antioxidants are molecules found in
6:51
fruit and vegetables and can help to
6:52
protect against free radical damage by
6:54
neutralizing free radicals fruits and
6:56
veg are often overlooked when it comes
6:58
to post-workout nutrition as we can
7:00
become very focused on macronutrients
7:02
like carbs and protein and forget about
7:04
the micronutrients however these are so
7:06
important for providing vitamins a c and
7:08
e which are all antioxidants I know it
7:11
sounds as though fats are not important
7:13
when it comes to fueling workouts but
7:15
the main reason as to why fats are
7:17
limited around training times is because
7:19
they are slow to be digested which isn't
7:22
ideal when we need fast acting energy
7:24
for performance or we want carbs and
7:26
protein to start the repair process ASAP
7:28
fats are super important in our diet so
7:31
and should be included in all of our
7:33
other meals fats provide us with energy
7:35
but are also a key nutrient for
7:36
supporting our hormonal health so I hope
7:39
this simplifies the aims of pre-intra
7:41
and post-workout nutrition and gives you
7:43
some ideas of how your diet can support
7:45
your goals as always if you have any
