Rodriguez F, Latt E, Jurimae J, Maestu J, Purge P, Ramson R, et al.
Int J Sports Med . 2015 Nov; 37(3):191-6. PMID: 26575404
The VO2 response to extreme-intensity exercise and its relationship with sports performance are largely unexplored. This study investigated the pulmonary VO2 kinetics during all-out 100-m front crawl whole stroke swimming...

Sousa A, Figueiredo P, Oliveira N, Oliveira J, Silva A, Keskinen K, et al.
Int J Sports Med . 2011 Sep; 32(10):765-70. PMID: 21913155
Studies that aim to characterize oxygen uptake kinetics in efforts above maximal oxygen consumption intensity are scarce. Our aim was to analyze the oxygen kinetics in a maximal 200-m front...

Barbosa T, Fernandes R, Keskinen K, Vilas-Boas J
Eur J Appl Physiol . 2008 Jan; 103(2):139-49. PMID: 18214521
The purpose of this study was to analyze the relationships between energy cost (C), swimming velocity (v), stroke frequency (SF) and stroke length (SL) in top-level swimmers. Eighteen elite swimmers...

Fernandes R, Keskinen K, Colaco P, Querido A, Machado L, Morais P, et al.
Int J Sports Med . 2007 Nov; 29(2):145-50. PMID: 17990207
The purpose of this study is to assess, with elite crawl swimmers, the time limit at the minimum velocity corresponding to maximal oxygen consumption (TLim-vVO2max), and to characterize its main...

Rodriguez F, Keskinen K, Kusch M, Hoffmann U
Int J Sports Med . 2007 Oct; 29(2):120-8. PMID: 17960507
Two models of a swimming snorkel connected to a portable metabolic cart (Cosmed K4 b2, Rome, Italy) were assessed using a gas exchange simulation system. Four standardized testing protocols were...

Keskinen O, Keskinen K, Mero A
Int J Sports Med . 2006 Nov; 28(5):407-13. PMID: 17111309
Exercise testing in water has been used to follow the progression of conditioning during regular training in swimmers. The present study examined the effects of pool length in eleven male...

Barbosa T, Fernandes R, Keskinen K, Colaco P, Cardoso C, Silva J, et al.
Int J Sports Med . 2006 Apr; 27(11):894-9. PMID: 16612740
The purpose of this study was to measure and compare the total energy expenditure of the four competitive swimming strokes. Twenty-six swimmers of international level were submitted to an incremental...

Barbosa T, Keskinen K, Fernandes R, Colaco P, Carmo C, Vilas-Boas J
Int J Sports Med . 2005 Dec; 26(10):841-6. PMID: 16320168
The purpose of this study was to identify the relationship between the bioenergetical and the biomechanical variables (stroke parameters), through a range of swimming velocities, in butterfly stroke. Three male...
