Physiological and skeletal muscle responses to high-intensity interval exercise in Thoroughbred horses.

Introduction: The purpose of this study was to determine whether acute high-intensity interval exercise or sprint interval exercise induces greater physiological and skeletal muscle responses compared to moderate-intensity continuous exercise in horses.

Methods: In a randomized crossover design, eight trained Thoroughbred horses performed three treadmill exercise protocols consisting of moderate-intensity continuous exercise (6 min at 70% VOmax; MICT), high-intensity interval exercise (6 × 30 s at 100% VOmax; HIIT), and sprint interval exercise (6 × 15 s at 120% VOmax; SIT). Arterial blood samples were collected to measure blood gas variables and plasma lactate concentration.

Phase angle is associated with sarcopenic obesity in post-stroke patients.

Background & Aims: Evidence is limited concerning the association between bioimpedance analysis-derived phase angle and sarcopenic obesity. This study examined this association in patients who underwent convalescent rehabilitation after stroke.

Methods: This cross-sectional study included hospitalized patients with post-acute stroke.
