Skate Nation (Saturday, BBC Two, 9am) Get your skates on for this high-paced spectacular.

Seven teams of speed, aggressive, hockey and artistic skaters are wheeled up and ready to roll in front of the judges as the entertaining new skating competition, presented by Sam Nixon and Mark Rhodes, continues.

Judges Camilla Dallerup (Strictly Come Dancing reigning champion and professional dancer); Asha Kirby (a professional skater); and Kevin Adams (a fitness instructor from BBC One’s Fame Academy), have to decide which five teams will make it through to Skate Camp and the next stage of the competition.

Each week, the skaters have to learn and perfect a new routine to perform in front of the audience. As the weeks go by, they will get more challenging and the teams must pull out all the stops if they want to win.

The Track and Field Show (Sunday, Channel 4, 8.25am) According to reports in the media, obesity is a growing problem in the UK.

So how should we be combating this? Well, apart from eating less junk food, the obvious answer is to do more exercise.

It can be difficult to motivate yourself to put on your tracksuit and trainers and head for the door for a run, even in good weather.

However, this new series, hosted by T4’s Rick Edwards, may put a spring in your step. It’s a magazine show featuring reports from across the country that aims to give viewers a grassroots look at the UK athletics scene.

And not everybody taking part has lungs like Paula Radcliffe, or a body as honed as a professional footballer. Instead, the show features reports on science, nutrition and equipment that could prove important and inspirational to everyone.

The Supersizers Eat (Monday, BBC Two, 9pm) It’s easy to turn our noses up at some of the bizarre dishes served up during the run of this series, but perhaps we shouldn’t be too quick to judge the food fads of the past.

Who knows, maybe in 30 years’ time, someone will make a programme asking how we ever managed to eat takeaway kebabs or think that a full English breakfast in a can was a good idea?

If you do want some reassurance that we’re currently living in a culinary golden age though, the last in the series of this show should supply it as Giles Coren and Sue Perkins head back to 44BC to look at what was on the menu in Ancient Rome.

While the Romans may have done a lot for us, you’ll probably conclude you can live without the recipe for a sauce made from rotten fish innards. However, the duo do discover the origins of pasta and pizza as they pay a visit to the Colosseum.
