Mission<\/h2>\n<\/div>

Since the age of 14, when I was given my first mountainbike (MTB), I was addicted to this new kind of cycling sport. Many years later this yielded to my first participation and completion of one of the most important MTB stage races in the world, the Transalp Challenge (TAC) 2003. This was the beginning of a new chapter in my life \u2013 the bikeeXtreme project was born. bikeeXtreme has been realized within the framework of my postgradual study of Sport Science to reach the degree of Doctor of Science (PhD) and peaked in the publication of my homonymous book: bikeeXtreme \u2013 Performance determining factors and vegan nutrition pattern to successfully complete the Transalp Challenge (ISBN: 978-3-8381-0912-1).<\/p>\n

This project was the first to enable an investigation to<\/h3>\n

i) study an extreme MTB stage race,
\nii) determine the exercise intensity of the TAC 2004,
\niii) study a female athlete during this difficult multi\u2013day MTB marathon race and
\niv) report the vegan dietary intake during the TAC 2004.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Start<\/strong> of project on 1st<\/sup> April 2004: Design and organisation of the field study as the core of data source.<\/p>\n

Completion<\/strong> of the field study (16th<\/sup> \u2013 24th<\/sup> July 2004) performed under the authentic race burden of the TAC 2004, officially held during 17th<\/sup> \u2013 24th<\/sup> July 2004.<\/p>\n

Collection<\/strong> of data sets recorded by subjects (25th<\/sup> July \u2013 30th<\/sup> September 2004) and subsequently evaluation and analysis of data.<\/p>\n

Presentation and promotion<\/strong> of results and findings at international scientific meetings and congresses in the area of Sport Science as well as publications in international peer\u2013reviewed journals and publishers in the area of Sport Science, Sport Medicine and Physiology since 2005, continuing into 2009.<\/p>\n

Being awarded<\/strong> of Young Reseracher Award, category \u201cSport Training\u201d (University of Prague, 2005), and of Doktoratsstipendium (University of Innsbruck, 2006).<\/p>\n

End of project<\/strong> was also the end of study on 21st<\/sup> April 2009.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
