Nitric oxide and exercise: what is the deal?

ninaNitric oxide is a gas which is soluble in the human body, and scientists who studied and elucidated physiological role of nitric oxide were awarded a Nobel Prize in 1998. While nitric oxide is responsible for a variety of functions such as mediation of neurotransmitters in memory and learning, it has received a great deal of attention in exercise physiology. Some have suggested that nitric oxide could be ergogenic aid, or in other words, enhance athletic performance.

Why do some people get fitter than others?

Two women running outdoorThe response to exercise training is often described in general terms, with the assumption that the group average represents a typical response for most individuals. However, in reality, it is more common for individuals to show a wide range of responses to identical exercise programs. In 1999, a large study published by Claude Bouchard and colleagues, reported that 20 % of us show little or no gain in maximal oxygen consumption (VO2max) with exercise training. This is a concern, since a high VO2max is associated with decreased rates of cardiovascular morbidity and mortality. Exploring the phenomenon of high responders and low responders following the same exercise program may provide helpful insights into mechanisms of training adaptation and methods of training prescription.

Hvordan trener skiskytere?

Junior VM i skiskyting 2015I dag, 18. febrauar, startet Junior-VM i skiskyting, og i år går den av stabelen i Minsk, Hviterussland. 16 utøvere fra Norge, åtte jenter og åtte gutter, drar med baggen stappfull av forventinger, forhåpninger, spenning, nervøsitet og glede. Baggen er også stappfull av fysisk og mental kapasitet som disse unge utøverne mellom 19 og 21 år allerede har rukket å bygge opp. Det ligger utallige timer trening i solskinn, øs pøsende regn, snøfokk og i gnistrende vakkert vintervær, både uti løypa og på standplass. Utøverne som drar til Junior-VM i Minsk er unge og de fleste har ikke deltatt i et stort internasjonalt skirenn tidligere. De viktigste målene for er glede, opplevelse og læring.

Periodically we hear from the media about footballers who incur heart complications during soccer matches, but watching exciting matches on TV may prove to be just as risky a “sport”. During the football World Cup which was held in Germany in 2006, German scientists studied the incidence of acute cardiac complications in the Munich area to determine whether the incidence of such events was increased in the days when the German team played one of their World Cup matches. Incidences of myocardial infarction, arrhythmias, cardiac arrest or activation of implanted defibrillators were examined.

The Greatest Game On Earth

Guest blogger Martin MaguireGuest blogger: Martin Maguire is the editor and author of Mersey Reds. Read why he thinks soccer is The Greatest Game On Earth

Football, soccer, the world game, the beautiful game, whatever you would like to refer to it as, has been played in some form for around 3000-5000 years.

However, football as we know it today was formed by eleven representatives from London clubs and schools at the Freemason’s Tavern on October 26, 1863. The outcome of the meeting was the formation of the Football Association, who amongst themselves created a single set of rules used to officiate over matches.

The first ever football match was played on 19th December 1863 on Barnes common at Mortlake, London between Barnes and Richmond Football Clubs. The game ended in a 0-0 draw.

Hilsen fra landslagssamling

Da har vi (kvinnelandslaget i fotball) vært i Albania en snartur og er tilbake i Norge for siste kamp i VM-kvaliken mot Nederland på onsdag. I kampen mot Albania var det kun nødvendig med ett poeng for å sikre deltakelse i VM-sluttspillet i Canada neste sommer. Dette gjorde laget med glans og sørget for en solid 11-0-seier der nede. Og det kunne vært enda mer.

Although Norway is not going to be playing this time, it is certain that the World Cup vibration will be felt here as well. Great matches and nice tricks are always fun to watch, even when your country is not playing.

Along with the regular schedule for the matches, this edition brings new features to the World Cup. Did you know that this will be the first time that referees can stop the match up to three times if “extreme weather” occurs? Heat can be very intense in many cities hosting the matches, especially in the north of Brazil where temperatures can reach up to 40 degrees Celsius…. during the winter. Heat, humidity and intense exercise is the perfect combination for dehydration, that is why the referees will be allowed to stop the matches for the players to rest a little, drink some water and run back to the field.

This will also be the most expensive football World Cup in history. The estimated cost of 15 billion Dollars is the sum of the three previous World Cups together. Differently from the 2002 and 2006 editions when the bill was paid mostly by private businesses, this time it is financed by the Brazilian government. This is the actual motivation for the protests occurring in Brazil, where the population advocates that this money should be used to improve education and public health, two major problems in the country.

It is also the first time the players will not be allowed to show anything hidden under their football shirts. You may think that it is all about the organization and to prevent unwanted messages, but the real reason is very clear: if the player lifts the t-shirt, the slogan of the sponsors (stamped on the shirt) will not appear on global television.

Finally, the most interesting news of this World Cup is that a paraplegic person will take the very first kick of the championship. Even though it was unimaginable a few years back, a group of scientists led by Brazilian researcher Miguel Nicolelis made it possible by developing a mind-controlled exoskeleton. A paralyzed teenager will stand up from the wheelchair, walk towards the midfield and take the first kick of the starting match Brazil vs. Croatia, tomorrow at 10pm (Norway time). It is not just a fancy machine, but a medicinal cornerstone that symbolizes new hopes for paralyzed patients.
