La période d’affûtage est une des phases essentielles dans la préparation physique d’un athlète, qui désigne les derniers jours ou les dernières semaines avant une échéance sportive importante. La difficulté de cette période cruciale réside dans l’équilibre que doit trouver l’entraîneur ou le préparateur physique, entre le repos nécessaire pour diminuer la fatigue accumulée et les stimulations nécessaires pour atteindre une performance optimale.
Quand doit-elle commencer ? Quelle est la stratégie la plus efficace ? Quels sont les éléments à prendre en compte pour l’adapter à chaque athlète ? Quels sont les gains attendus ?
Ce sont à toutes ces questions qu’ont tentés de répondre les auteurs de cet ouvrage, Iñigo Mujika et Laurent Bosquet, experts en physiologie de l’effort et mondialement reconnus en préparation physique.

Paratriathlon will debut at the Rio 2016 Paralympic Games, but research documenting the physiological attributes and training practices of elite paratriathletes is lacking. This case study reports on the physiology and training of a Long Distance World Champion male paratriathlete (below the knee amputee) over 19 months. His body mass and skinfolds declined respectively by ≈4 kg and 30% in 2 months, and remained relatively constant thereafter. His swim test velocity increased by 4.4% over six months, but declined back to baseline thereafter. His absolute and relative cycling maximal aerobic power improved progressively by 21.8% and 32.6%, respectively. His power output at the individual lactate threshold (ILT) improved by 39.5% and 51.6%, and his power output at the onset of blood lactate accumulation (OBLA) by 59.7% and 73.4%. His maximal running aerobic velocity improved by 12.8%, and his velocity at ILT and OBLA increased by 38.9% and 44.9%, respectively. Over 84 weeks he performed 813 training sessions (248 swim, 229 bike, 216 run, 120 strength), i.e. 10±3 sessions/week (mean±SD). Swim, bike and run volumes were 709 km (8±3 km/wk), 519 h (6±4 h/wk) and 164 h (2±1 h/wk). Training at intensities below ILT, between ILT and OBLA, and above OBLA for swim were 82%±3%, 14%±1%, 4.4±0.4%; bike 91%±3%, 6.2%±0.5%, 3.3%±0.3%; run 88%±1%, 8.0%±0.3%, 3.5%±0.1%. The training volume for each discipline was lower than previously reported for competitive able-bodied Olympic distance triathletes. He won the Long Distance World Championship in 8h 14min 47s, nearly 30 min faster than his nearest competitor.

The January 2015 issue of Volata Magazine publishes a central report dedicated to Basque cycling, one year after the disappearance of the team Euskaltel Euskadi. In this issue, there is an article I wrote in which I describe my perception about the team and my own experience working in it. I hope you like it.

No blog posts since September 2nd! I’ve been meaning to post something for a while now, but I never seemed to find the time, the energy or the inspiration to do it. The main reason for this dry spell is that I have been lecturing and consulting away lately, and going around the world (several times, I should say) while doing so.
Let’s see: on September 2nd I flew to Bogotá, Colombia, to lecture at the 4th International Congress on Sports Training; still in September, I lectured for the medical doctors of the Netherlands Olympic Committee not far from Amsterdam; and at the Gatorade Sports Science Institute International Congress in Mexico City.

Leeds welcomes Le Tour de France (Photo: Inigo Mujika)
A couple of weeks ago I had the great pleasure to participate in the Second World Congress of Cycling Science in Leeds. Magnificently organized by Dr. James Hopker, Professor Louis Passfield, Dr. John Dickinson and Sarah Coakley of the University of Kent and endorsed by the Union Cycliste Internationale, the conference coincided with the Grand Depart of the Tour de France 2014 and was an opportunity to share knowledge and research from the world of cycling science.
In addition to being a member of the Scientific Committee, I did a keynote presentation entitled “A scientific approach to training and tapering for road cycling events” (see abstract below), and I also organised a symposium on “The role of strength training within endurance cycling” (see abstract below), in collaboration with my friends Bent Rønnestad from Lillehammer University College, Norway, and David Martin of the Australian Institute of Sport. Last but not least, we had the opportunity to ride part of the opening stage of the Tour de France 2014.

Detailed accounts of the training programs followed by today’s elite triathletes are lacking in the sport-science literature. This study reports on the training program of a world-class female triathlete preparing to compete in the London 2012 Olympic Games. Over 50 wk, she performed 796 sessions (303 swim, 194 bike, 254 run, 45 strength training), ie, 16 ± 4 sessions/wk (mean ± SD). Swim, bike, and run training volumes were, respectively, 1230 km (25 ± 8 km/wk), 427 h (9 ± 3 h/wk), and 250 h (5 ± 2 h/wk). Training tasks were categorized and prescribed based on heart-rate values and/or speeds and power outputs associated with different blood lactate concentrations. Training performed at intensities below her individual lactate threshold (ILT), between the ILT and the onset of blood lactate accumulation (OBLA), and above the OBLA for swim were 74% ± 6%, 16% ± 2%, 10% ± 2%; bike 88% ± 3%, 10% ± 1%, 2.1% ± 0.2%; and run 85% ± 2%, 8.0% ± 0.3%, 6.7% ± 0.3%. Training organization was adapted to the busy competition calendar (18 events, of which 8 were Olympic-distance triathlons) and continuously responded to emerging information. Training volumes were 35–80% higher than those previously reported for elite male and female triathletes, but training intensity and tapering strategies successfully followed recommended best practice for endurance athletes. This triathlete placed 7th in London 2012, and her world ranking improved from 14th to 8th at the end of 2012.
