The researchers used the data set to tabulate the typical, desirable VO2 max for a healthy person at every age from 20 to 90, creating specific parameters for fitness age. The concept is simple enough, explains Ulrik Wisloff, the director of the K. G. Jebsen Center of Exercise in Medicine at the Norwegian University and the senior author of the study. “A 70-year-old man or woman who has the peak oxygen uptake of a 20-year-old has a fitness age of 20,” he says. He has seen just this combination during his research.
The researchers have used all of this data to create an online calculator that allows people to determine their VO2 max without going to a lab. You’ll need your waist measurement and your resting heart rate. To determine it, sit quietly for 10 minutes and check your pulse; count for 30 seconds, double the number and you have your resting heart rate. Plug these numbers, along with your age, sex and frequency and intensity of exercise, into the calculator, and you’ll learn your fitness age.
The results can be sobering. A 50-year-old man, for instance, who exercises moderately a few times a week, sports a 36-inch waist and a resting heart rate of 75 — not atypical values for healthy middle-aged men — will have a fitness age of 59. Thankfully, unwanted fitness years, unlike the chronological kind, can be erased, Dr. Wisloff says. Exercise more frequently or more intensely. Then replug your numbers and exult as your “age” declines. A youthful fitness age, Dr. Wisloff says, “is the single best predictor of current and future health.”
Skip the queue for fat loss with this strategic workout by March 2017 cover model Claudia Jovanoski.Words/workout: Claudia Jovanovski (pictured)Photography: James PatrickTime-poor gymmers are all too familiar with supersetting to save time. Pushing out two moves successively with little or no rest between is among the best fitness hacks going – especially for impatient types.Tri-sets step things up again, running together three fatiguing moves, meaning the workout is performed at high intensity for a shorter duration than standard circuits.According to a study at the Catholic University of Brasilia and the Eastern Illinois University, multiple sets (MS) and tri-sets (TS) were found to impact neuromuscular variables and body composition.The results of the study indicate that a multi-set regimen burns more body fat than circuit-like training.In tri-sets, the usual rest period between sets is used to complete a set of another move.Research also shows that the hormonal response to such unrelenting exertion favours optimal muscle growth (which in the real world equals tone and a faster metabolism).You can either pair exercises that are noncompeting (i.e. work opposing muscle groups), or you can pair exercises that target the same muscle group.The downside of this fast, furious method is a power penalty, which reduces the amount of resistance you can use and hence limits potential for strength gains.While some experts claim that staggering moves with opposing muscle group pairings circumvents this risk, the nervous system’s response to this training method necessarily inhibits power. Most experts maintain that classic training is best for strength goals.For more advanced users, tri-sets can be combined with classic sets by incorporating one or two strength moves performed classically (with or without intervening moves that keep the body moving without inviting fatigue).This workout uses sprints, so factor that in, whether you want to do a bike sprint in the gym or a dash on the track.On your marks, get set…1.
