Measurements of respiratory exchanges in genuine exercise conditions are undoubtedly of interest to further define the energy needs of endurance horses. However, the equine K4b 2 , the gas exchanges portable device validated for equines, has not been used in Arabian endurance horses yet. Therefore, the objective of this study was to implement field cardio-respiratory measurements in such horses using the equine K4b 2 in order to assess energy expenditure (EE). Measurements of heart rate (HR), oxygen uptake (VO 2 ), carbon dioxide production (VCO 2 ), respiratory frequency (RF), tidal volume (VT) and minute expired volume (VE) were carried out at rest and during a 20-min submaximal incremental field exercise in five trained Arabian endurance horses equipped with the K4b 2 system. The relationship between HR and VO 2 was determined for each horse. EE of the exercise session was calculated from direct VO 2 measurements and individual HR-VO 2 regression. Out of the five horses, four tolerated the equipment. Respiratory and metabolic variables at rest and during exercise, as well as EE measured at the different gaits, were consistent with reported values in exercising horses: VO 2 ranged from 4.8 to 54.1 ml/min per kg from rest to canter, respectively, and EE from 82 to 1095 J/min per kg BW. The 20-min exercise session EE accounted for 6258 and 6332 J from direct VO 2 measurements and individual HR-VO 2 regression, respectively, which did not differ significantly. Providing an adaptation period and several technical adjustments, the present equine K4b 2 could be used to assess EE in Arabian endurance horses in a controlled environment. The prediction of EE from the individual VO 2 -HR relationship might be an alternative method to evaluate EE when VO 2 measurements are not possible.

Kinematical changes in swimming front Crawl and Breaststroke with the AquaTrainer® snorkel

et al. 2010

The aim of the present study was to assess the kinematical changes when swimming maximal bouts in Front Crawl and Breaststroke with the AquaTrainer snorkel. Thirteen male swimmers (7 at Breaststroke and 6 at Front Crawl) of national level performed randomly two maximal bouts of 100-m swims: one bout using the AquaTrainer snorkel (snorkel swim) and another one without the snorkel (free swim). The swims were videotaped in sagittal plane with a pair of cameras providing 2D kinematics evaluation. The following measures were assessed: swimming performance (T100), stroke cycle period (P), stroke rate (SR), stroke length (SL), swimming velocity (v), swimming efficiency as estimated by the stroke index (SI), speed fluctuation (dv) and the mathematical characterisation of dv. T100 was significantly higher when swimming with the snorkel than in free swimming at Breaststroke (Delta = 6.26%) and at Front Crawl (Delta = 4.75%). P, SR and SL, as well as SI and dv did not present significant differences. The main finding of the study was that changes in the swimming velocity imposed by the use of the Aquatrainer do not seem due to changes in general kinematics or swimming efficiency.

Summary In the last decade there have been significant technological advances and increases in the availability of portable diagnostic equipment for use in the assessment of athletic performance. The design and application of appropriate exercise tests are critical factors for the diagnosis of conditions affecting equine performance and it is therefore necessary for veterinary surgeons using such equipment to develop an understanding of appropriate exercise testing methods. This is the first in a series of three papers covering exercise testing in the equine athlete, interpretation of heart rate and rhythm during exercise and interpretation of dynamic upper respiratory tract function. In this first paper, both performance and clinical exercise testing in the equine athlete are reviewed.

Validation of a portable equine metabolic measurement system

Abstract: The K4b2 system could be used to improve knowledge of the energetic cost in different equine sports disciplines and offer the opportunity to undertake performance tests with genuine track conditions, on ridden or harnessed horses, rather than under laboratory conditions.
