the activity regularly. If you're only cross-training occasionally, use heart rates 10-15bpm below your usual levels as a starting guide and adapt them as necessary. If, however, it's going to be a more regular feature on your schedule, you should start to use
machinery with strong electric currents – motorised treadmills affect many watches, often to the point where just walking elicits heart rates above 200! Similarly, runners who live on the flight path to an airport can experience strange readings when low
on your first few runs back, to give them a chance to strengthen up. Your resting heart rate may have risen, and your pace for each of your training heart rate zones will almost certainly have dropped. You should pay attention to what your HRM tells you
though, it does the basics well enough.Contact www.timex.comTimex BodyLink Trail Runner £180 Tested by Big KevFeatures Simultaneous display of heart rate and speed distance, 2 linked interval timers, latitude, longitude and altitude, navigation
Q I know three ways of calculating maximum heart rate (MHR): 220 – age; 214 – (0.8 x age); and 205 – 1/2 age. For a 30-year-old, they all come out at 190, but for a 60-year-old, the results are 160, 166 and 174 – a large range. Which is the most
for someone in their 40s, because maximum heart rate declines as we get older. The rough rule of thumb for estimating your age-predicted maximum heart rate is to subtract 0.8 times your age from 214 for men, or subtract 0.9 times your age from 209 for women
Q Following your advice, I did a treadmill test using a heart rate monitor to work out my maximum heart rate. The result was 177bpm. However, during 40-minute steady runs my pulse easily reaches 165bpm, about 94 per cent of max! Am I training too
Q During a recent race, while I was running very comfortably, my heart rate suddenly shot up to nearly 40 beats above my usual level and remained there for the rest of the run. At no time did I feel ill or even out of breath, but understandably I
at a slower pace, rather than fewer at a faster tempo. A good rule of thumb devised in the USA is to train up to a heart rate calculated by taking your age from 180. So at 40 you train up to a HR of 140. If you have to walk occasionally to keep your HR
