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

allowed sustained high fat oxidation during subsequent exercise despite increased insulin concentration and attenuated ketosis during the inter-exercise period. 40 g of maltodextrin intake only partly affected the enhanced exercise induced fat oxidation. Whether intake of protein or carbohydrate in the

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

(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

protocols. 2 Also, a large capacity to sustain high intensities during prolonged submaximal work has been reported. For example, the ventilatory (VT) and respiratory compensation (RCT) thresholds have been measured at ∼70% and ∼90% of VO 2 max, respectively, 1 – 3 and a gross efficiency of ∼24% has been

Considerable research has examined the prevalence of and risk factors for injuries sustained by marching artists ( Beckett et al., 2015 ; Bischof, 1994 ; Harman, 1993 ; Kilanowski, 2008 , Knapik et al., 2007
