Philip Marron recently undertook a VO2 max test using a treadmill in Tallaght Sports Centre. The testing involved analysing his specific VO2 and determining at what heart rate his body crossed the threshold of aerobic and anaerobic intensity. Once this was measured, Philip's training workout zones could be calculated much more accurately. The objective of all this is to fine tune his training to ensure he peaks for target competitions. Using a heart monitor will enable him to be certain he is training in the correct workout zone and not just be relying on how he "feels " on any given day. Well worth considering having this done irrespective of what standard you are competing at.
