MuhtasariThe Training Impulse (TRIMP) model, developed by Eric Banister and colleagues (1975), quantifies the physiological stimulus of a training session by combining duration and intensity. The Banister fitness-fatigue model proposes that training effects on performance follow two opposing dynamics: fitness (beneficial) accumulates with time constant tau_f (~42 days) and fatigue (temporary decrement) accumulates faster but decays quickly (tau_d ~5-10 days). By tracking TRIMP and modeling these two processes, coaches can predict performance trajectories and optimize training load. Although superseded by newer frameworks, the Banister model remains influential and intuitive.Lactate threshold, also termed the onset of blood lactate accumulation (OBLA), is the exercise intensity at which blood lactate concentration increases rapidly and non-linearly. Initially defined by Klaus Wasserman in 1973, the concept describes the physiological transition from aerobic to anaerobic metabolism. As exercise intensity increases, lactate production and clearance remain balanced until a critical threshold is exceeded, after which lactate rapidly accumulates in the blood, signaling a shift toward anaerobic energy pathways. This parameter is crucial in endurance sports and clinical exercise assessment.
