This book was released on 2017-03-03 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: Upper body power (UBP) is one of the most important factors affecting the performance of cross-country skiers during races. Although some initial studies have already attempted to predict UBP, until now, no study has attempted to apply machine learning methods combined with various feature selection algorithms to identify the discriminative features for prediction of UBP. The purpose of this study is to develop new prediction models for predicting the 10-second UBP (UBP10) and 60-second UBP (UBP60) of cross-country skiers by using General Regression Neural Networks (GRNN), Radial-Basis Function Network (RBF), Multilayer Perceptron (MLP), Support Vector Machine (SVM), Single Decision Tree (SDT) and Tree Boost (TB) along with the Relief-F feature selection algorithm, minimum redundancy maximum relevance (mRMR) feature selection algorithm and the Correlation-based Feature Subset Selection (CFS). Several models have been developed to predict UBP10 and UBP60 of cross-country skiers using two datasets. 10-fold cross validation has been performed for model testing. The efficiency of the prediction models has been calculated with their multiple correlation coefficients (R’s), standard error of estimates (SEE’s) and mean absolute percentage errors (MAPE’s). The results emphasize that GRNN-based prediction models show higher performance than the other regression methods. Also, using less number of predictor variables than the full set of predictor variables can be useful for prediction of UBP10 and UBP60 with comparable error rates.

Book excerpt: Doctoral Thesis / Dissertation from the year 2017 in the subject Engineering - Computer Engineering, grade: 100.00/100.00, Çukurova University, language: English, abstract: The purpose of this thesis is twofold. The first purpose is to develop new hybrid feature selection-based maximal oxygen uptake (VO2max) prediction models using for the first time the double and triple combinations of maximal, submaximal and questionnaire variables. Several machine learning methods including Support Vector Machine, artificial neural network-based and tree-structured methods combined individually with three feature selectors Relief-F, minimum redundancy maximum relevance (mRMR) and maximum-likelihood feature selector (MLFS) have been applied for model development. The second purpose is to design a new ensemble feature selector, which aggregates the consensus properties of Relief-F, mRMR and MLFS to produce more robust decisions about the set of relevantly identified VO2max predictors and to create more accurate prediction models. Using 10-fold cross validation on three different datasets, the performance of prediction models has been evaluated by calculating their multiple correlation coefficients (R’s) and root mean squared errors (RMSE’s). The results show that compared with the results of the other regular feature selection-based models in literature, the reported values of R and RMSE of the hybrid models in this thesis are considerably more accurate. Furthermore, prediction models based on the proposed ensemble feature selector outperform the models created by individually using the Relief-F, mRMR or MLFS, achieving similar or ideally up to 12.46% lower error rates on the average.

Book excerpt: In sport disciplines such as running, ice skating, bicycling and cross-country skiing the aerodynamic drag force constitutes the major obstacle to overcome. Furthermore, in ski jumping and in various activities involving a ball the aerodynamic lift force comes in addition into action. This book describes the various sport disciplines on the basis of aerodynamic analysis and also cover the biomechanics part by illustrative performance examples. Such treatment of the underlying physical phenomena of sport activities gives a valuable supplement to existing literature on sport. The reader will also be guided to references which exist for the various topics discussed, so she or he can go into a deeper study of the particular sport activity at wish.

Book excerpt: Hunter Allen and Andy Coggan, PhD have completely revised the book that made power meters understandable for amateur and professional cyclists and triathletes. Power meters have become essential tools for competitive cyclists and triathletes. No training tool can unlock as much speed and endurance as a power meter--for those who understand how to interpret their data. A power meter displays and records exactly how much energy a cyclist expends, which lends unprecedented insight into that rider's abilities and fitness. With the proper baseline data, a cyclist can use a power meter to determine race strategy, pacing, and tactics. Training and Racing with a Power Meter makes it possible to exploit the incredible usefulness of the power meter by explaining how to profile strengths and weaknesses, measure fitness and fatigue, optimize workouts, time race readiness, and race using power. This new edition: Enables athletes to predict future performance and time peak form Introduces fatigue profiling, a new testing method to pinpoint weaknesses Includes two training plans to raise functional threshold power and time peaks for race day Offers 75 power-based workouts tuned for specific training goals This updated edition also includes new case studies, a full chapter on triathlon training and racing, and improved 2-color charts and tables throughout. Training and Racing with a Power Meter, will continue to be the definitive guide to the most important training tool ever developed for endurance sports.

This book was released on 2016-08-22 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the nation's economic activities, security concerns, and stewardship of natural resources become increasingly complex and globally interrelated, they become ever more sensitive to adverse impacts from weather, climate, and other natural phenomena. For several decades, forecasts with lead times of a few days for weather and other environmental phenomena have yielded valuable information to improve decision-making across all sectors of society. Developing the capability to forecast environmental conditions and disruptive events several weeks and months in advance could dramatically increase the value and benefit of environmental predictions, saving lives, protecting property, increasing economic vitality, protecting the environment, and informing policy choices. Over the past decade, the ability to forecast weather and climate conditions on subseasonal to seasonal (S2S) timescales, i.e., two to fifty-two weeks in advance, has improved substantially. Although significant progress has been made, much work remains to make S2S predictions skillful enough, as well as optimally tailored and communicated, to enable widespread use. Next Generation Earth System Predictions presents a ten-year U.S. research agenda that increases the nation's S2S research and modeling capability, advances S2S forecasting, and aids in decision making at medium and extended lead times.
