Abstract

ObjectivesTo profile performance and physiological responses to typical patterns of match-day activity for second-half soccer substitutes.DesignDescriptive.MethodsFollowing a warm-up, 13 male team sports players underwent ∼85 min of rest, punctuated with five min rewarm-ups at ∼25, ∼50, and ∼70 min,...

Despite increased ratings of perceived exertion and elevated blood lactate concentrations (p&#x2009;&#x2264;&#x2009;0.05), sprint times were maintained throughout exercise, whereas peak power increased (&#x223C;7.8%, +294&#x2009;W; p&#x2009;=&#x2009;0.006) pre- to post-exercise.ConclusionsAt the point of simulated pitch-entry, body temperature and physical performance responses were not maintained from warm-up cessation despite typical substitute-specific match-day practices being employed in thermoneutral conditions.
