Do You Need Salt Tablets?

Many endurance athletes take salt tablets, but do we really need them? I spoke with the sodium and hydration master aka Alan McCubbin to break down everything you need to know about sodium, hydration and endurance exercise.

Here’s what we discussed:
 

Why is sodium is important for sports like triathlon?

• When we sweat during exercise, sodium is the main mineral we lose along with chloride
• The main electrolyte in our blood is also mainly sodium, and this plays a big role in moving water around the body

 Are there currently any guidelines around sodium replacement?

• The guidelines are currently very vague
• There aren’t really any specific guidelines around sodium replacement during exercise apart from a broad statement from the American College of Sports Medicine indicating that people should replace sodium when large losses occur, but they don't define what a large loss is

What research is currently underway to find some answers?...

How to Lose Weight & Maintain Energy for Ironman Training

Most athletes are looking to be in peak physical condition for their A race. For endurance events like Ironman where you have to carry your weight across a long distance, performance can be improved with a good power to weight ratio. But it’s a delicate balance between being light, strong and fast and falling into a hole because you’ve under fuelled too aggressively to get there.

Here are my 7 Tips To Drop Body Fat While Still Maintaining Energy Levels And Performance Through An Ironman Build:

1. Eat Strategically

• Have a periodised approach to your nutrition
• You shouldn’t eat the same thing every day – your nutrition should match your training load
• Your nutrition should look completely different on your lighter training days vs a double session hard training day vs a long endurance ride & run off the bike type day
• Without a specific nutrition plan perfect for you, you run the risk of getting...

With Cairns Ironman just around the corner, I’m deep into writing race nutrition plans for our athletes. This morning on Coffee & Questions I wanted to share with you some strategies to assist with training and racing in the heat.

One of the biggest impacts of heat exposure when exercising is its effects on the gut. This is exacerbated when our core temperature gets >39°C

What happens to the gastrointestinal tract (GIT)?

• Redistribution of blood flow away from the GIT towards working muscles and peripheral circulation
• Results in decreased perfusion of organs in the abdominal cavity causing GIT ischemia (lack of oxygen)
• PLUS sympathetic activation – fight or flight response – you don’t want to spend energy digesting food when you’re trying to run away from a lion
• Suppressed gastric emptying, digestion and absorption

All of this happens with exercise – the longer and more intense – the worse it is. And it is...

A question I get asked frequently in the clinic – What do I eat before a race?

Generally, I'd suggest organising a specific RACE NUTRITION PLAN for your specific event as everyone is different, but here are a few general guidelines to help you get started...

Pre-Race Meal Timing - How long do you have?

What you eat before a race depends on how long you’ve got to digest and absorb it. If you have multiple hours (for e.g. Byron Bay OD which doesn't start to lunchtime), something heavier and more solid is probably going to be ok.

Compared to a shorter time-frame i.e. 1 hour or less, something smaller and easily digestible will work best. In saying that, everyone is different and you need to figure out what works best for you.

If you know you are a nervous racer and food sits in your stomach for a while, I'd suggest getting up a little earlier to ensure you have something to eat 2-2.5 hours prior to the race start.

Go for a smaller volume but...

Happy Fri-Yay !!

When it comes to Sports Drinks, there are far too many choices!

Which sports drink has the most electrolytes? Which sports drink has the most sodium? Which sports drink is isotonic? What sports drink has the least sugar? Which sports drink is the best for hydration?

And most importantly, what sports drink is the best choice for optimal performance? Let’s have a look… 

What are we looking for in a sports drink?

Ultimately, we’re looking for a product that helps meet our fuelling and hydration needs. Sports drinks should be designed with a combination of different carbohydrates, electrolytes and of course fluid to keep you hydrated and performing at your best. But not all sports drinks are created equal…

Carbohydrate

As a general rule, most sports drinks contain between 6-8% carbohydrate. So, in 100mL of the product (made up to the correct concentration), they contain between 6-8g of carbohydrate. Anything higher can delay the rate your stomach empties...

We lose water on a daily basis. We exhale water when we breathe, we lose water through our skin as sweat and we excrete water in our urine. Without regularly replacing this fluid we become dehydrated. We can’t train our bodies to adapt to dehydration, unfortunately. It’s not something you can become good at. Even mild dehydration can have noticeable negative effects. Let’s take a look…

1. Fatigue

Perhaps the most noticeable effect of dehydration is a general feeling of fatigue. Being dehydrated is often the cause of headaches or headache-type symptoms such as reduced focus, dizziness, light-headedness, feeling tired and low mood. If you are feeling these effects, try drinking more water before jumping straight to taking painkillers.

2. Mental function

As dehydration increases, mental performance decreases. There is a noticeable impairment in short-term and working memory and our visual-motor function. Dehydration also impacts concentration and the ability to...

I often see endurance athletes struggling to manage their body composition. They strive to be leaner so drastically cut calories and then suffer for it with reduced energy levels, poor training performance and increased risk of illness and injury...

I despise the word ‘diet’ and don’t even get me started on ‘detox’. The idea of a quick fix is appealing but unfortunately, there is no magic pill for weight loss... 

Diets are often gimmicky, unsustainable and are not going to provide adequate fuel to keep up with the often-high load of triathlon training. There are some very real consequences to inappropriate weight loss such as altered hormones, reduced immune function, impaired growth and development and don’t forget warped psychological state (Yes, being ‘hangry’ is a real thing).

You’ll notice decreased muscle strength, anaerobic power and endurance capacity; none of which are helpful when training or racing. Success as a...

I can’t be the only one that’s noticed Bioelectrical Impedance Analysis (BIA) scans popping up in just about every gym 12-week challenge, or ‘get fit for summer’ promo. These scans are advertised as a ‘new’ and ‘improved’ way to accurately measure your body composition that’s not going to cost you an arm and a leg. But should you be relying on this measure when it comes to achieving your goals?

It’s a BIG NO from us. Let me tell you why…

How BIA works:

This method of body composition measurement relies on different types of tissue in our bodies having different levels of conductivity. The machine sends a small current between the body parts in contact with the machine (either two or four points) and creates a measure of body composition depending on the response to this current. This is where we start to run into issues...

BIA machines with only two contact points (i.e. hand-to-hand, or foot-to-foot)...
