High intensity training (HIT) is a variant of single-set training. It is becoming increasingly popular in strength training practice. Contrary to the large number of research on multiple-set training, empirical investigations addressing HIT are rare. There is evidence that an important factor for muscle hypertrophy is the muscle time under tension (TUT). However, scientific knowledge about the optimal length of the TUT is lacking. Therefore, the aim of the present study was to compare the effects of a rather short TUT (20–40 s) with a rather long TUT (50–70 s) during HIT strength training. Nine experienced recreational sportsmen completed a ten week HIT strength training either with the short or the long TUT.

In 2008, the World Anti-Doping Agency officially launched the biological passport. The first validated module to operate was the blood module to fight erythropoietin (EPO) and blood transfusion abuse. It has been quite efficient to catch some doped athletes, but above all, was very good in reducing the prevalence of doping. It is unclear if athletes stopped doping or have adapted and are taking micro doses of EPO or transfusing small blood volumes. More recently, the steroid module was released, but until now, the number of urine adverse passport cases is very low.

Long term storage of the anti-doping samples and their reanalyses becomes today more and more a trend in the anti-doping community. The procedure has been implemented by the anti-doping authorities for the samples of the Tour de France and for the Olympic Games since Athens 2004 and has been always presented as a good tool to deter doping habits in top level sport. Recently, the World Anti-Doping Code introduced the possibility for anti-doping organizations to store the athletes’ samples up to ten years.

The Athlete Biological Passport detects the effect of doping on the organism through longitudinal monitoring of biomarkers. The first quantitative analysis is performed by a software algorithm based on the Bayes theorem, taking into account previous values of the athlete. Profiles which have been found as abnormal with this technique are submitted for qualitative analysis to an expert panel regarding potential causes for the abnormality. Possible causes include analytical shortcomings, Pathologies, extremes of physiological regulation or doping.

Created in 2008, the Cycling Anti-Doping Foundation (CADF), is a non-profit organization acting under Swiss law that became fully independent in 2013. Unique model for a sporting organization, the CADF’s role is to manage autonomously the Anti-Doping programme, on behalf of the Union Cycliste Internationale (UCI). The relationships between UCI and CADF are regulated by a contract signed by the CADF Foundation Board and UCI management. The CADF activities are conducted in compliance with the World Anti-Doping code [1], the UCI Anti-Doping rules [2].

Poor governance of sport, in particular all the policy implications that take the place of sport are causing many negative headlines in the press today. We have to do with doping, corruption, violence, rigging the competition, trafficking of players and all this corresponds to only the visible part of the iceberg. Sports ethics must be promoted to ensure good governance in sport suffers and this is undoubtedly these ethical issues are in the center of the concerns and challenges ahead for the IOC and for all national sports federations.
