The purpose of this work is to develop VO2max prediction models by using non-exercise, submaximal and hybrid variables by using Support Vector Machines (SVM), Multi-layer Feed-forward Artificial Neural Networks (MFANN) and Multiple Linear Regression (MLR) on different data sets. Using 10-fold cross validation on four different data sets, the performance of prediction models has been evaluated by calculating their multiple correlation coefficients (R’s) and standard error of estimates (SEE’s). The results show that SVM-based VO2max prediction models perform better (i.e. yield lower SEE’s and higher R’s) than the prediction models developed by MFANN and MLR. We also propose a new approach based on the elimination of irrelevant samples during the training phase for improving the performance of SVM and MFANN models for prediction of VO2max. The performance of the proposed approach has been compared with the two widely used outlier detection algorithms. The results show that the improved SVM-based and MFANN-based VO2max prediction models yield noticeable decrements in error rates compared to that of regular and outlier-based SVM and MFANN VO2max prediction models.

MAX O2 reinvents aerobic training....and makes it better! MAX O2 represents an exciting breakthrough in aerobic training, offering a completely new approach based on the combined effect of VO2 max and something called the lactate threshold. Building on this revolutionary concept, MAX O2 will help you squeeze every last ounce of benefit out of your aerobic workouts. Learn: * How the FITTprinciple (Frequency, Intensity, Time, and Type) can help you see the same progress in your cardiovascular training as in other parts of your workout! * How to build aerobic training into any conditioning program including HFL's own bodybuilding and martial arts workouts. Also, benefits and myths of crosstraining. * How to avoid injuries that can be caused by high-intensity aerobic work by using great new exercises like slideboarding...today's hottest solution for low-impact, high-intensity conditioning. * How to take advantage of new reasearch about the three different muscle fiber types, which ones are used for which sports, and what's the best way to train them. (Bodybuilders, here's the secret to dropping bodyfat without losing muscle mass!) Now, using the scientific guidelines and approach revealed in MAX O2, you can have the ideal aerobic program for your individual goal and body type. "For the past ten years, Health for Life has been one of our most dependable sources of scientifically based literature, providing information on methods of training in a concise and easy to understand manner...a gold mine of useful information for the athlete..." Mike Woicik, Strength and Conditioning Coach Dallas Cowboys, Super Bowl Champions

The smaller-sized fēnix 6S Pro and fēnix 6S Sapphire multisport GPS watches let you add mapping, music, intelligent pace planning and more to your workouts — without adding bulk to your wrist. Advanced training status, running/cycling dynamics and environmentally adjusted VO2 max estimates are right at your fingertips. Plus, a first-of-its-kind Pace Pro™ feature keeps your pacing strategy on track with grade-adjusted guidance as you run a course. Designed for all-day wearability, these versatile watches come with preloaded TOPO maps and ski maps for more than 2,000 worldwide ski resorts. Other highlights include enhanced wrist heart rate (the data and information provided by these devices is intended to be a close estimation of your activity and metrics tracked, but may not be precisely accurate), smart notifications (when paired with a compatible smartphone), Pulse Ox (this is not a medical device and is not intended for use in the diagnosis or monitoring of any medical condition) sensing and Garmin Pay™ contactless payments (not all countries and payment networks are eligible). To maximize on-wrist use time, customizable power manager modes let you see and control how various settings and sensors impact battery life.
