The benefits of HIIT training

The benefits of HIIT training

There’s an ongoing debate about cardio: which one is more beneficial? HIIT or steady state cardio? It depends on your goal and even your bodytype. Some people can get away with the mind numbing steady state cardio – which is a lot more comfortable, let’s be honest. However it doesn’t work for everyone. If you have been doing that for quite some time it might have stopped working for you – because let’s be honest, your body will get used to most things and will adapt in time. Then it might be a wise idea to step it up to HIIT cardio.

Anyone can benefit from HIIT cardio: elite athletes and everyday people who just want to lose a bit of weight.

So what are the benefits of HIIT?

#1 When you perform high intensity training, glycogen is your preferred fuel that is stored in your muscles. To do more high intensity workouts we need a bigger reserve of muscle glycogen stores. This will allow you to train harder for longer. In addition it will allow for a greater carbs tolerance which means you can eat more carbs and store them as refuel, instead of fat.

#2 Improved aerobic fitness: your body can take in more oxygen and deliver it to your muscles, enabling you to perform faster for longer.

#3 Greater fat burning: some time ago it was the ‘fat burning zone’ on the cardio machine. If you wanted to burn fat, you had to be in the fat burning zone. HIIT burns more fat, because the quicker you deplete your muscle glycogen stores, the sooner your body will tap into your stored fat for fuel. HIIT training depletes muscle glycogen stores because the main fuel for HIIT is glycogen.

#4 Improved capacity for exercise: if you’re doing high intensity – or I could call it metabolic type – weight training, HIIT can increase your capacity for exercise. By increasing our aerobic capacity we can go harder for longer which can help you burn more calories = lose more weight.

#5 Improved insulin sensitivity: One major risk factor for developing type 2 diabetes is reduced insulin sensitivity. If you have normal insulin sensitivity, then insulin can help you shuttle the carbs into your muscles, instead of your fat cells.

#6 You boost your metabolism and get an afterburn: Resistance training has a different effect on your body opposed to endurance training. Resistance training increases excess post exercise oxygen consumption (EPOS). EPOS describes the calories you burn immediately after the training session, also known as the ‘afterburn’ effect.

Soy: good or bad?

Soy contains 26% protein. It has the highest protein content amongst the plants. It is also the highest quality protein amongst the legumes.
Grains are typically low in lysine, beans are typically low in sulfur, methionine and cysteine. However the level of sulfur amino acids is higher in soy than in other beans.
Soybeans are high in fats, too. Most legumes (except peanut) contains 2-14% of fat, soy contains 31% of fat. Most fats in soy is unsaturated.
A serving of soy provides about 8 gr of dietary fibre. However some soy foods are processed in a way that decreases the fibre content, like tofu or soy milk. Processing soy at a high temperature can denature some of the proteins and reduce their quality.
Soy provides important nutrients: calcium, vitamin B12, iron, magnesium and selenium.

Interestingly, whole soybeans are rarely consumed in Western countries. The majority of soy in the diet comes from the refined products that are processed from the soybeans.

The fatty acids in soybeans are mostly Omega-6 polyunsaturated fats. This can be problematic because too many Omega-6s in the diet can lead to inflammation and all sorts of health issues. For this reason, it is very important to avoid soybean oil (and other vegetable oils high in Omega-6) and processed foods that contain it.

The nutrition composition of soy products depends on the type of soy food. Refined soy products, like soy protein and soy bean oil might not be that nutritious at all.

There is some evidence that soy can lower cholesterol levels, although studies show conflicting results. Men who consume soy are at a lower risk of developing prostate cancer in old age.

Soy contains large amounts of biologically active compounds called isoflavones, which function as phytoestrogens… that is, plant-based compounds that can activate estrogen receptors in the human body. These isoflavones are classified as endocrine disruptors, chemicals that interfere with the normal function of hormones in the body. The key isoflavones in soy are genistein, daidzein and glycitein. This can cause reduced estrogen activity due to the isoflavones blocking the actual, more potent estrogen from binding, or it can lead to an increased estrogen activity due to the isoflavones activating the receptors.

Animal studies show that soy isoflavones can cause breast cancer. There are also human studies showing that soy isoflavones can stimulate the proliferation and activity of cells in the breasts.
This may indicate an increased risk of breast cancer, which is the most common cancer in women.

Even though men have some amount of estrogen, having significantly elevated levels is not normal. Therefore, it seems logical that increased estrogen activity from soy isoflavones could have some effects on men. Many believe that soy can reduce testosterone levels, but the effect appears to be weak and inconsistent.

The isoflavones in soy also function as goitrogens, which are substances that interfere with thyroid function. They can inhibit function of the enzyme thyroid peroxidase, which is essential for production of thyroid hormones.

It is important for women who are pregnant, plan on becoming pregnant, or are breastfeeding, to avoid soy and other sources of endocrine disrupting compounds.
