VO₂ max is one of the key indicators of physical fitness and endurance. In this article, you will learn what it means, how it is measured, what influences it, and how you can gradually improve it through training, recovery, and proper nutrition. Because better fitness is not just about numbers, but mainly about energy, performance, and the joy of movement.
Creatine is no longer just a concern for bodybuilders. What does science say about it, what forms of creatine can you choose, and why is Creaport a great choice for both professionals and amateurs?
For regular sports activities lasting up to about 60 minutes and at normal temperatures, plain water is sufficient. An electrolyte drink makes sense when you sweat significantly and lose minerals – typically during exertion lasting over an hour, in heat, or during endurance activities. The duration of the activity, intensity, temperature, and how much salt you lose in sweat are all factors. Let's break it down so that you can easily decide what to grab from the fridge next time.
Electrolytes are minerals – primarily sodium, potassium, magnesium, calcium, and chloride – that carry an electric charge in the body and facilitate the transmission of nerve signals, muscle contractions, and water balance. During sports, you lose them through sweat, and if you don't replenish them, performance declines, and cramps and fatigue can occur. Therefore, athletes need them more than people without exertion. This article will explain what electrolytes do, what happens when you have a deficiency, and how to replenish them.
When choosing an electrolyte drink, focus mainly on the sodium content (key for hydration), type based on tonicity (isotonic is universal), amount of sugar depending on whether you need energy, and form – powder, tablets, or ready-to-drink. Choose based on the duration and intensity of your activity, not by the most appealing label.
The difference lies in the concentration of the solution compared to blood. A hypotonic drink is thinner and is absorbed the fastest – it is suitable for quick hydration and in heat. Isotonic has a similar concentration to blood and replenishes fluids and energy at the same time, making it a universal choice for endurance sports. Hypertonic is thicker, rich in carbohydrates, and serves more as a source of energy and replenishment after exercise than for hydration during it.
Calcium and magnesium are minerals that work together in muscles but have opposite roles – calcium triggers muscle contraction, while magnesium relaxes it. Calcium is the main building block of bones, while magnesium contributes to energy production, muscle relaxation, and recovery. Athletes often have a higher need for magnesium because they lose it more through sweat and consume it more quickly. Supplement the one you are deficient in based on symptoms and diet.
The best sources of electrolytes combine food and specific supplements. Sodium is provided by salt and baked goods, potassium by bananas and potatoes, magnesium by nuts and seeds, and calcium by dairy products. During prolonged exertion, especially in heat, it is practical to supplement electrolytes with an isotonic drink, which addresses both minerals and energy at once. For regular activity, a varied diet covers needs, while supplements address specifics based on exertion and symptoms.
Hot days often reduce appetite and lead to meals that are light but sometimes insufficiently filling and nutritionally inadequate. Most often, protein is lacking, which is key for maintaining muscle mass, hormonal balance, and satiety that protects us from snacking on various treats.
Summer brings movement, longer days, and outdoor sports, but high temperatures can significantly hinder performance. Find out what to watch out for when exercising in the heat, how to prevent overheating, and how to support your body to manage an active summer safely and with greater confidence.
A half marathon requires two things at once: enough energy for 21 km and a stomach that won't stop you halfway. Proper nutrition starts several days before the race, continues on the course, and doesn't end at the finish line. We bring you tips on what to eat and when in preparation.
A bar that tastes good doesn't have to be just a candy full of empty calories. The right bar can be a wholesome snack, fuel for our athletic performance, a helper during a diet, or a sensible dessert substitute. And as you rightly suspect, the difference lies not in the appealing color of the bar's packaging, but in the composition and thus the purpose for which the bar was created.
“Wellbeing” is a state in which our mind is naturally calm and our body has enough strength and energy. However, modern life often disrupts this balance. Too little sleep, stress, an overburdened liver from medication, alcohol, or poor diet. It is no surprise that we feel irritable, drained, and lacking motivation. The good news is that balance can be restored relatively quickly – if we decide to take action.
Valentine’s Day is usually associated with romantic dinners, flowers, and chocolate. In the fitness world, we tend to add a protein dessert to the mix – and sometimes a bit of guilt when the “all-you-can-eat celebration” goes a little too far.
Magnesium isn’t just “one” thing – individual forms differ in their effects and absorption. Discover which option is best suited for you.
7 myths that stop you from enjoying its full potential!
Magnesium (Mg) is a mineral that plays a fundamental role in the proper functioning of our body. Although the influence of magnesium on the health of our heart, bones, and muscles is well known, its effects on athletic performance and recovery are often significantly underestimated.
Imagine working out under the open sky, surrounded by the sounds of the forest or flowing rivers. Outdoor exercise is not just about performance itself, but also about how wonderful it is to connect your body and mind with nature.
Discover why creatine is one of the most effective food supplements for strength and performance – when to use it, how it works, and what happens if you stop the supplementation.
Regular movement is the first step toward better fitness, health and mental well-being for all of us. If you are preparing for more demanding outdoor activities such as mountain hiking, trail running or long bike rides, it is a good idea to gradually prepare your body for this type of load.
The secret to the success of runners, as well as all other athletes, lies not only in training but also in a well-thought-out diet, hydration, and recovery. Discover 10 key principles that will help you get the most out of every step!
