1
I think you've just split HIIT up into two broad categories.
2
EMOM or EMOM, every minute on the minute,
3
where it was kind of this four minutes of maybe not max intensity,
4
but you're working hard with these different exercises and then you're having a minute off.
5
So four minutes on, one minute off.
6
And you contrasted that with sprint interval training
7
or SIT where it's kind of 30 seconds on as hard as you can and two to three minutes off.
8
You've just been through the specific benefits of sprint interval training.
9
How does that compare to EMOM every minute on the minute?
10
Is it the same?
11
Is it similar?
12
Or are there, you know, some quite significant differences in the adaptations that we are going to get?
13
Yes.
14
So if we're looking at the HIIT interval, so high intensity.
15
Can I just pause you there, Stacey?
16
So I've got this clear in my head.
17
HIIT is the umbrella term, right?
18
Which there's many ways of doing HIIT.
19
One way of doing HIIT is sprint interval training.
20
Another way is EMOM.
21
Is that accurate?
22
B-mom is a type of workout in there.
23
High-intensity interval training is the umbrella term.
24
Sprint interval training is a subset of that umbrella term.
25
The other half of that is what people typically think of as HIIT,
26
where we are doing between one and four minutes of work at 80% to 90%
27
or an eight to nine on the scale of one to 10, and we have one to two minutes recovery between those intervals.
28
So another form of HIIT that is beneficial.
29
Yeah, okay, got it.
30
So when we look at that, it's more, you're spending more time in intensity, that's not quite as high as sprint interval.
31
So you have more of a calorie bearing, which people are concerned about for some weight loss.
32
You also are creating a greater time under stress that's going to improve mitochondrial health.
33
And we're also improving blood flow because we have more time of muscle perfusion.
34
So that means we're gonna get the impetus for building more red cell,
35
more plasma volume, and having better blood pressure control and actual change of blood flow.
36
So when we're looking at what's happening from a little bit lower intensity
37
and having more time under tension or more time under intensity,
38
it is truly a metabolic response for muscle perfusion.
39
So that means more blood flow to the muscle, more oxygen carrying capacity, more calorie burn.
40
And you're also building more lean mass in that time frame
41
because you need more muscle to be able to do the activity.
42
The other thing about that little bit lower intensity, longer duration is the post-exercise response.
43
So we look at post-exercise response.
44
This is the big thing that we hear a lot is perimenopausal, postmenopausal women shouldn't do HIIT training because it increases cortisol.
45
So there's a caveat in there.
46
If you're going to hit class, they try to fill the class up 45 to 60 minutes.
47
You can't hold proper intensity that long.
48
So you will get an increase in cortisol because cortisol is released during exercise.
49
But you won't get the post-exercise response that you need to bring it down.
50
Because in that 45 to 60 minute class, you really aren't doing high intensity work.
51
you're in moderate intensity.
52
You're in that gray zone.
53
So if I bring it back and say, we're going to do it properly, where we're doing two rounds of four minutes with one minute off,
54
and you're going to really work to maintain that intensity.
55
Post-exercise, you get a boost of growth hormone and testosterone, that drop cortisol.
56
So just like your resting heart rate starts to drop as you get fitter over three to four weeks,
57
your baseline cortisol drops over time.
58
So now you are not as sympathetically driven.
59
You can get out of that tired but wired state and have better ability to hit parasympathetic responses.
60
So this is where we have the nuance of what is
61
really high intensity interval training versus what is the fitness world projecting high intensity interval training
62
and that's why i'm like
63
when we're talking about it we have to be very specific in what
64
that intensity is and how long we're holding it
65
because a true hit class shouldn't be any more than 30
66
minutes you have a little bit of warm-up you do true intensity and recovery
67
and they have a little bit of a cool down a
68
true sprint interval session might be 10 minutes total where you
69
have a warm-up you do a couple of true intervals with the recovery
70
and a little cool down it doesn't take a lot of time
71
but they're both very powerful yeah this is great
72
because as we've already acknowledged many people many women feel time pressured and actually
73
a lot of your recommendations are very very time efficient um you know really time efficient
74
and i think there's a really interesting point
75
that i just want to highlight we're basically saying
76
that there are certain hormonal changes
77
that happen as a woman approaches menopause there are things
78
that you can do with specific forms of exercise to mitigate the effects off that.
79
One of those things is this high intensity type work.
80
But if you're not careful, you won't do it correctly and you'll end up in moderate intensity.
81
So moderate intensity is not giving you the stimuli that you are wanting from the high intensity.
82
And I guess relating to what what you just said, because I think a lot about the stress load of exercise in an already busy,
83
stressed out population.
84
I know for me, for example, and we'll probably get to zone two in just a minute,
85
one of the things I enjoy doing is doing one hour on my indoor carol bike at very low intensity.
86
I might listen to a podcast, I might prepare for a podcast, I might whatever, because I know it's a very low stress load on my system.
87
It keeps me pretty parasympathetic and doesn't drive me into sympathetic and it doesn't take me long to recover from that.
88
but what was really interesting what you said true hit true
89
high intensity although it feels very intense actually is not driving you into
90
that sympathetic overly stressed state after the workout it's helping you come down into parasympathetic into
91
that relaxation state that's a kind of critical point i think for people to understand
92
because it's this whole you know stressed out, we're tired and wired, we can't switch off.
93
High intensity is actually going to potentially help with that, isn't it?
94
Absolutely.
95
And that's the thing, that's a messaging that gets mixed up when we talk about it in the fitness world.
96
Because there's this big push for high intensity interval training, because we see that gives the best body composition outcomes.
97
But when it's not done correctly, we see so many women that get overstressed, they get injured, They maintain that tired but wired.
98
They don't see results.
99
But when you pull it back and you actually hit it hard when you need to hit it hard, recover properly from that, then hit it hard again and recover,
100
then you do get that post-exercise response because your body's like, whoa, that was a really strong stress.
101
I need to be able to overcome it.
102
So I need to repair the tissues, drop the inflammation, drop the oxidation,
103
and I need to be able to fully relax to garner that adaptation.
104
So we see women who are doing true HIIT training, then subsequently sleep better.
105
If you sleep better, then everything gets better.
106
Thank you.

Come esercitarsi con questo video

  1. Ascolta tutto il video una volta senza parlare e annota le parole che non conosci.
  2. Fai shadowing frase per frase a velocità normale, ripetendo ognuna finché il tuo ritmo coincide con quello di chi parla.
  3. Registrati e confronta con l’originale, facendo attenzione a parole come interval, sprint, cortisol.

Cos'è la tecnica dello Shadowing?

Shadowing è una tecnica di apprendimento delle lingue supportata da studi scientifici, originariamente sviluppata per la formazione dei traduttori professionisti e resa popolare dal poliglotta Dr. Alexander Arguelles. Il metodo è semplice ma potente: ascolti un audio in inglese di madrelingua e lo ripeti immediatamente ad alta voce — come un'ombra che segue il parlante con un ritardo di solo 1–2 secondi. A differenza dell'ascolto passivo o degli esercizi di grammatica, lo shadowing costringe il tuo cervello e i muscoli della bocca a elaborare e riprodurre simultaneamente i modelli di discorso reale. La ricerca dimostra che migliora significativamente la precisione della pronuncia, l'intonazione, il ritmo, il discorso connesso, la comprensione dell'ascolto e la fluidità del parlato — rendendolo uno dei metodi più efficaci per la preparazione alla prova di speaking dell'IELTS e per la comunicazione reale in inglese.
