Runners

Almost all novice runners take fewersteps than the oft-cited ideal stridefrequency of 180 steps per minute (spm).So researchers got a group of newbies to
run at a frequency 10 per cent higher than their usual step rate. The results were startling: a 14 per cent reduction in peak joint force on the knee.

Coffee helps you run faster, for further – and now it seems it might help you recover faster too. After a dose of caffeine, volunteers were able to perform more reps of a
weight-lifting exercise but paradoxically reported less muscle soreness over the next two days. It's not clear exactly why cof ee might help keep DOMS at bay...

Sometimes less really is more – according to new research, a daily workout of 30 minutes shifts more blubber from a novice exerciser than a full hour's effort. It might seem counterintuitive, but the shorter sessions left volunteers full of energy,which tipped over into more activity over the rest of their day. The long slogs, meanwhile, just tired the exercisers out so they became far more sedentary.

As temperatures plummet, new research gives runners a reason not toresent the chill. In a study published in the Journal of Clinical Investigation, volunteers spent two hours a day sitting in a room set to 17C. Six weeks later, and they'd raised their energy expenditure enough to lose 5.2 per cent of their body fat.

Another reason to do as you're told and eat your greens. Sulforaphane, a compound found in broccoli, helped protect against cartilage deterioration in a recent University of East Anglia study. The researchers say that sulforaphane might one day help treat – and even prevent – painful conditions such as osteoarthritis. Sulforaphane is less bioavailable the longer broccoli is cooked, so lightly steam yours to keep things crunchy.
