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.

This book was released on 2021-12-03 with total page 145 pages. Available in PDF, EPUB and Kindle. 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 Synopsis Upper Body Characteristics Related to Double Pole Performance in Female Cross Country Skiers by :
Download or read book Upper Body Characteristics Related to Double Pole Performance in Female Cross Country Skiers written by and published by . This book was released on 2016 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The purpose of the current study was to correlate upper body (UB) lean mass (UBLM), UB maximal strength (UBMS), and average power production during a 3-min ski ergometer (SERG) test to predict the dependent variable, a one-kilometer uphill double pole time trial (DPTT) on snow. We hypothesized UBLM would be most important to performance. All tests were conducted within four weeks of completing the championship phase of a Division I cross country (XC) ski season. Skiers (n=10; all females) performed the mass-start DPTT on snow (i.e., criterion measure), SERG, and UBMS separated by at least a few days recovery. Lastly, body composition was determined via dual-energy x-ray absorptiometry (DXA) with a focus on UB mass characteristics (i.e., trunk + arm lean mass). A significant (p = 0.02) correlation was observed between DPTT and UBLM. No significant (p > 0.05) correlations were observed for UBMS or SERG vs. DPTT. Thus, our hypothesis was supported and we suggest female, competitive cross country skiers work to build functional UB lean mass to best prepare for utilizing the ever popular and evolving double pole technique."--Abstract.
