sustainment of performance output, while also minimizing excessive muscle damage. Along with NMF having an effect on the ability to sprint, decreases were observed within the mediolateral vector (PL1D side ) and anteroposterior vector (PL1D fwd ). This may mean that either directly, or due to modifications in

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 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

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

(Figures  4A and 4B ), indicating a close pattern of physiological demand. A relatively large plateau in V ˙ O 2 versus workload relationship was observed for most of the tests. Foster et al 22 pointed out to the remarkable ability of the skaters to rapidly attain and sustain maximal level of V ˙ O 2

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

LT and LTP were visually obtained by plotting blood lactate against running velocity and were approved by 2 independent reviewers. LT was accepted as the first sustained
