New research confirms the superior health benefits of cross-country skiing

I have been writing lately about cross-country skiing and also previously about its great effects on fitness and health. There has also been large epidemiological studies showing its benefits.

New research from Finland also confirms this as it shows that cross-country skiing is actually superior to other sport and physical activity habits in terms of health (all-cause mortality). This is because researchers in this recent study took also into consideration other and total physical activity habits (as well as numerous other confounding factors that could have affected the results), and showed that cross-country skiing showed independent effects on mortality, thus skiers lived longer.

Like I have previously written, cross-country skiing activates basically all of our muscles stimulating cardiovascular function and metabolism substantially. It is also great “natural” interval training, even when practised at slow pace, particularly when you are skiing in mountaneous terrain. Therefore, if you have a chance, cross-country skiing is really something that could be practised to be physically active and fit!

Roller skiing- what a perfect way to get fit!

Cross-country skiing is well known to be one of the best exercises to get fit and improve health. Cross-country skiing activates basically all of your muscles (legs, gluts, abdomen, back and arms etc.), and thus creates great metabolic and circulatory demands for whole body simultaneously, which is the reason why it increases fitness very effectively. An indication of this is that world’s best cross-country skiers are known to have the highest maximal oxygen consumption values of all human beings. Cross-country skiing requires snow, but skiing can be done also by roller skiing, which is enjoyable and perfect way to exercise particularly during summer time. An interesting thing also is that skiing not only activates your skeletal muscles, but also your brain.

Roller skiing is enjoyable exercise activity and perfect way to be outside and get fit!

A picture of Tour de France rider shows what extreme training can do for your blood volume and vasculature

Most remarkable sport event in July, Tour de France, is over and was again won by Chris Froome. This blog is not so much focused on which rider or athlete wins or loses in some competition and I will therefore leave those things for the journalists. During the Tour an interesting and memorable picture was however taken and posted on Instagram by one of the riders, which nicely shows what endurance training is capable of doing in our body. Some said that rider should see his doctor, but his legs are not neccesarily showing any bad injuries or fatigue but are simply a result of extreme endurance training caused mainly by two main physiological factors.

How fit is your fat?

I wrote in my previous blog that I last week attended Exercise Metabolism congress in Gothenburg, Sweden. After a first mountain bike race for the season (what a struggle) on Saturday followed by a families get-to-together with my wife’s uni friends over the weekend, I also had close to 7 hours on Sunday during an easy cycling session over 170 kilometers to sort out my thoughts regarding the topics covered in the meeting. Thus, here are my major thoughts based on the congress that I was thinking when trying to improve my fat metabolism, muscle capillarization and heart’s stroke volume by low intensity, long-duration cycling yesterday.

Exercise, metabolism and aging

Exercise has numerous effects on bodily functions and the current state-of-the-art knowledge in the field will be updated in a Cell symposium that starts today in Gothenburg, Sweden.  Recent Cell Metabolism issue also deals with the topics in more detail also in a written form beforehand and looks like it will be an exciting meeting again with world-leading professors talking about their research and that of others.

High-intensity interval training and glucose uptake and blood flow in skeletal and cardiac muscle

High-intensity interval training is powerful and time-efficient training method to improve fitness and health. According to recent results high-intensity interval training is as effective as continous moderate intensity aerobic training to improve insulin-stimulated glucose uptake in skeletal muscles in middle-aged men, while neither of these training modes improved free-fatty acid uptake studied at resting baseline.
