Comparison of ventilatory and oxygen consumption measurements of yearling Thoroughbred colts and fillies exercising unridden on an all-weather track
Sex effects on ventilatory and oxygen consumption (V̇O ) measurements during exercise have been identified in humans. This study's aim was to evaluate the hypothesis that there are sex effects on ventilatory and V̇O measurements in exercising, untrained yearling Thoroughbreds (Tb). Forty-one Tb...

| description | Sex effects on ventilatory and oxygen consumption (V̇O
) measurements during exercise have been identified in humans. This study's aim was to evaluate the hypothesis that there are sex effects on ventilatory and V̇O
measurements in exercising, untrained yearling Thoroughbreds (Tb). Forty-one Tbs (16 colts, 25 fillies; 19.8 ± 1.4 months old) were recruited. Physiological, ventilatory and exercise data were gathered from horses exercising unridden at high intensity on an all-weather track from a global positioning-heart rate unit and a portable ergospirometry system. Data were analysed with an unpaired Student's t-test and the Benjamini-Hochberg correction for multiple testing (P ≤ 0.05 significant). Mean bodyweight (BW, P = 0.002) and wither height (P = 0.04) were greater for colts than fillies. There were no differences in physiological and exercise data and absolute peak V̇O
between groups. However, fillies had a higher mass specific peak V̇O
(P = 0.03) than colts (121.5 ± 21.6 mL/kg.min vs. 111.9 ± 27.4 mL/kg.min). The peak breathing frequency was greater for fillies (P |

; P = 0.01) were greater for colts; there were no differences for peak V

Further research is required to investigate the ventilatory differences and how they may change with maturation and impact performance.</description><identifier>ISSN: 1090-0233</identifier><identifier>EISSN: 1532-2971</identifier><identifier>DOI: 10.1016/j.tvjl.2023.106041</identifier><identifier>PMID: 37931872</identifier><language>eng</language><publisher>England</publisher><subject>air ; air flow ; Animals ; body weight ; exercise ; Exercise Test - veterinary ; Female ; Heart Rate ; Horses ; Humans ; lungs ; Male ; Oxygen ; Oxygen Consumption ; Respiration ; t-test ; Thoroughbred ; tidal volume ; Weather ; yearlings</subject><ispartof>The veterinary journal (1997), 2023-10, Vol.300-302, p.106041-106041, Article 106041</ispartof><rights>Copyright © 2023 The Authors.
