The average peak measured values from the inspiratory muscle strength test to fatigue for each time-point for n = 20 Thoroughbred horses in an inspiratory muscle training (IMT) treatment (Tr, n = 10) or control (Con, n = 10) group.

Data presented as mean ± SEM and analysed using a mixed linear model with P≤0.05 significant. *significantly different from T0. §significantly different from the Tr group.

数据以平均值±标准误（Standard Error of the Mean, SEM）呈现，采用混合线性模型进行统计分析，显著性判定标准为P≤0.05。*表示与T0组存在显著差异；§表示与Tr组存在显著差异。
