Paper accepted in Applied Physiology, Nutrition, and Metabolism

The paper entitled “Estimating peak oxygen uptake based on postexercise measurements in swimming“, authored by Diego Chaverri, Thorsten Schuller, Xavier Iglesias, Uwe Hoffmann, and Ferran A. Rodríguez has been accepted for publication in Applied Physiology, Nutrition, and Metabolism (JCR IF: 2.339).

The study assessed the validity of postexercise measurements in estimating VO2peak in swimming. The authors compared VO2 measurements during supramaximal exercise with various commonly adopted methods: 1) first 20-s average; 2) linear and semilogarithmic backward extrapolation at different time intervals; and 3) a recently developed HR- VO2 modelling procedure. The results confirmed that the new modelling procedure based on postexercise VO2 and HR measurements is a valid and accurate procedure for estimating VO2peak in swimmers and avoids the estimation bias produced by other methods.

This project was carried out in collaboration with the Institut für Physiologie und Anatomie, Deutsche Sporthochschule Köln, Germany.

Congratulations to all!

Paper accepted in Applied Physiology, Nutrition, and Metabolism

The paper entitled “The effects of intensity on V̇O2 kinetics during incremental free swimming“, authored by Kelly de Jesus, Ana Sousa, Karla de Jesus, João Ribeiro, Leandro Machado, Ferran A. Rodríguez, Kari L. Keskinen, João Paulo Vilas-Boas, and Ricardo J. Fernandes has been accepted for publication in published ahead of print in Applied Physiology, Nutrition, and Metabolism (JCR IF: 2.225).

The study showed that the fast and slow components of VO2 kinetics changed from low to severe swimming intensities (i.e. progressively greater amplitudes and faster time constants) across a 7×200 m incremental protocol. Within the bouts performed at low-moderate intensity swimmers showed great stability in all kinetics parameters, whereas at the heavy and severe intensities, faster kinetics and a pronounced slow component occurred.

The study was carried out in the Centre of Research, Education, Innovation and Intervention in Sport of the Faculty of Sport, and the Porto Biomechanics Laboratory, LABIOMEP, University of Porto, Portugal, in collaboration with the Finish Society of Sport Sciences, Helsinki, and our research group.

Congratulations to all!

Paper published in Experimental Physiology

The paper entitled Exercise modality effect on VO2 off-transient kinetics at VO2 intensity”, authored by Ana Sousa, Ferran A. Rodríguez, Leandro Machado, João P. Vilas-Boas and Ricardo J. Fernandes has been published ahead of print in Experimental Physiology (JCR IF: 2.871).

The study shows that the on and off-transient VO2 kinetics responses from rest to a square-wave transition exercise at the severe-intensity exercise domain (i.e. 100% of VO2max) in four groups of athletes (swimmers, runners, rowers and cyclists) of comparable level are well described by a double exponential model and are symmetrical in shape. However, a larger off-transient amplitude in running compared to cycling, associated to larger VO2peak, and a slower rate of VO2 decrease during the fast phase of recovery in swimming comparing to rowing and cycling, appear to corroborate the hypothesis that sport discipline- or exercise-related differences would contribute to somewhat distinct off-transient VO2 kinetics pattern at this particular exercise domain.

The study was carried out in the Centre of Research, Education, Innovation and Intervention in Sport of the Faculty of Sport, and the Porto Biomechanics Laboratory, LABIOMEP, University of Porto, Portugal.

ALTITUDE Project. Paper published in Medicine & Science in Sports & Exercise

The paper entitled Altitude Training in Elite Swimmers for Sea Level Performance (Altitude Project)”, authored by Ferran A. Rodríguez, Xavier Iglesias, Belén Feriche, Carmen Calderón-Soto, Diego Chaverri, Nadine B. Wachsmuth, Walter Schmidt, and Benjamin D. Levine, has been published ahead of print in Medicine & Science in Sports & Exercise (JCR IF: 4.459).
This controlled nonrandomized parallel groups trial, involving 61 elite swimmers from 8 nations, investigated the effects of performance, VO2 and hemoglobin mass of 4 training interventions: living and training at moderate altitude (2,320 m) for 3 and 4 weeks (Hi-Hi3, Hi-Hi), living high and training high and low (Hi-HiLo, 4 weeks), and living and training at sea level (SL) (Lo-Lo, 4 weeks). We conclude that a well-implemented 3- or 4-week training camp may impair performance immediately, but clearly improves performance even in elite swimmers after a period of SL recovery. Hi-HiLo for 4 weeks improves performance in swimming above and beyond altitude and SL controls, through complex mechanisms involving altitude living and SL training effects.
Congratulations to all!

Rodríguez, Xavier Iglesias, Belén Feriche, Carmen Calderón-Soto, Diego Chaverri, Nadine B. Wachsmuth, Walter Schmidt, and Benjamin D.

Aquest estudi controlat de grups paral·lels, en el que participaren 61 nedadors de 8 països, investiga els efectes sobre el rendiment, el VO2 i la massa d’hemoglobina de 4 tipus d’entrenament: viure i entrenar a altitud moderada (2,320 m) durant 3 0 4 setmanes (Hi-Hi3, Hi-Hi), viure en altitud i entrenar en altitud i més baix (Hi-HiLo, 4 set manes), i viure i entrenar a nivell del mar (SL), (Lo-Lo, 4 setmanes). Es conclou que un camp d’entrenament ben implementat de 3 o 4 setmanes pot perjudicar el rendiment de forma immediata, però millorar-lo clarament després d’un període de recuperació a nivell del mar. Hi-HiLo durant 4 setmanes millora el rendiment en natació per sobre i més enllà dels altres grups que viuen i entrenen en altitud o a nivell del mar, a travès de complexos mecanismes que impliquen efectes de la permanencia en altitud i l’entrenament a nivell del mar.

Paper published in the European Journal of Sport Science

The paper entitled Training load quantification in elite swimmers using a modified version of the training impulse method”, authored by Amador García-Ramos, Belén Feriche, Carmen Calderón, Xavier Iglesias, Anna Barrero, Diego Chaverri, Thorsten Schuller and Ferran A. Rodríguez, has been published in  the European Journal of Sport Science (JCR IF: 1.314).
The study compares Banisters original TRIMP method (1991) and a modified calculation procedure (TRIMPc) based on the cumulative sum of partial TRIMP, and to determine how each model relates to the session rating of perceived exertion (s-RPE), a HR-independent training load indicator.

2014 in review

The WordPress.com stats helper monkeys prepared a 2014 annual report for this blog.

Here’s an excerpt:

A New York City subway train holds 1,200 people. This blog was viewed about 5,700 times in 2014. If it were a NYC subway train, it would take about 5 trips to carry that many people.
