One of the aims of performance analysis is to provide an opportunity to predict sport performance in order to be well prepared for the future competitive scenarios ( Volossovitch, 2013 ). In fact, a fundamental question in this topic is whether research can be reliable enough to predict the future performance, rather than merely recounting the past ( Sampaio and Leite, 2013 ).
Unsurprisingly, the matches are widely discussed amongst fans, sports journalists, academic experts and elite coaches, sometimes using player and team evaluation

distances such as a multi-stage Ironman triathlon covering ten times the Ironman distance within ten days, performance progressively declined over the days ( Herbst et al., 2011 ; Knechtle et al., 2014 ).
In that regard, a Double Iron ultra-triathlon covers 7.6 km of swimming, 360 km of cycling and 84.4 km of running, a Triple Iron ultra-triathlon covers 11.4 km of swimming, 540 km of cycling and 126.6 km of running, a Quintuple Iron ultra-triathlon covers 19 km of swimming, 900 km of cycling and 211 km of running and a Deca Iron ultra-triathlon covers 38 km of

strongly influenced by anthropometric features, it is also possible that developmental changes of the body build modulate the relationship between balance and skiing results to some extent ( Claessens et al., 1999 ).
The aim of this study was to explore the relationship between balance ability and skiing performance among young alpine-skiers. Namely, the study examined skiing competition results and their relationship with balance ability and anthropometric variables over two competitive seasons. Additionally, the relationships between the main anthropometric features
phenomenon ( Ng et al., 2011 ) can be improved by a regular resistance or weight training program. In addition to the aforementioned merits, anaerobic performance was enhanced after regular resistance training ( Fatouros et al., 2005 ; Santos and Janeira, 2012 ).
Considering the aspect of muscular performance, multiple sets or sessions of resistance training were superior to one single set or session of resistance training because of more training volume or loading ( Bottaro et al., 2011 ; Krieger, 2010 ). However, in contrast to the above-mentioned studies regarding

Many athletes use dietary supplements in an effort to maximize performance. It is widely accepted that ingestion of dietary supplements that may nutritionally affect intracellular and extracellular buffering capacity are an evidence-based strategy for improving sports performance ( Maughan, 2014 ).
Consumption of dietary sodium bicarbonate (SB) prior to exercise induces alkalosis by increasing blood bicarbonate pool and pH. This in turn enhances the buffering capacity of the extracellular space in the working muscle by influencing the efflux of

Numerous studies have described the importance of muscle strength and power generated by the arms and legs in swimming performance and showed that those variables were highly correlated with the results of speed tests ( Maglischo et al., 1985 ; Morrison et al., 2005 ; Maszczyk et al., 2012 , 2014), mainly in short-distance events. Furthermore, a linear relationship has been reported between maximum power and performance in 25-m and 50-m swimming events (Hawley and Williams, 1991, 1992).
Previous studies have recommended that various training

Soccer, with millions of licenses, is probably the world’s most popular sport. Player’s performance has been associated with technical, tactical, physical, physiological and mental factors ( Stølen et al., 2005 ). Regarding physical/physiological elements, strength and power have been considered equally important as endurance ( Mohr et al., 2003 ), and significant relationships have been observed between strength, acceleration and movement velocity ( Wisløff et al., 2004 ). Furthermore, an increase in players’ strength has been linked to
