is derived predominantly from sustainable aerobic pathways, 4 , 5 while work above CP requires a greater anaerobic contribution, drawing on a finite capacity of work known as W ′. The precise physiological underpinnings of W ′ remain elusive; initially thought to be a finite amount of energy drawn

Identifying the critical intensity of exercise is a crucial aspect for predicting performance, prescribing exercise training, and evaluating the effectiveness of training interventions. 1 , 2 This critical intensity is thought to represent the upper boundary of sustainable performance (ie

the present study was only 38.3°C (0.4°C). Other high-intensity STHA studies reported similar thermal impulses and also failed to achieve a sustained elevation in body core temperature ≥38.5°C resulting in minimal physiological adaptations. 9 – 11 In combination, these data suggest that short

implication for long-term training adaptations. 33 Interestingly, our findings indicate that for the loaded conditions, RCOD performance were faster at 15-second postwarm-up intervention, and this PAP effect was sustained up to 8-minute postwarm-up intervention. For the unloaded condition, such RCODs

Flat-water sprint kayaking over 200 m is a timed cyclical event with large upper-body physical demands. 1 – 5 Paddlers must generate high levels of sustained muscle power during each stroke from the catch phase to the exit phase to maximize boat acceleration and minimize deceleration. 2 , 6 A

maximal aerobic speed (MAS) is recommended. 8 However, continuous work at MAS can only be sustained for ∼6 minutes in well-trained runners and cyclists. 9 , 10 Therefore, there is a quest for developing HIT sessions that optimize time ≥90% VO 2 max by balancing work and recovery durations and

The critical speed (CS) model describes the capacity of an individual to sustain particular work rates as a function of time, via the demarcation of 2 physiological parameters; CS and the curvature constant ( D ′). 1 – 5 The CS represents the highest speed that can be sustained for an extended

. Numerous studies have suggested that there are at least 2 apparent discontinuities or thresholds in the blood lactate response to incremental exercise. 1 – 3 The first of these is associated with the initial intensity at which there is a sustained increase in blood lactate concentration ([BLa − ]) above
