8 22 Soccer athletes, for example, regularly repeat short, high-intensity efforts, interspersed with longer intervals of rest or submaximal exercise over ≥30 min. 2 The typical distance covered by top-class centre-midfielders is ∼9 13 km/match, 1 2 which is comprised of 70% low-intensity activity and ∼150 250 brief intense actions (average sprint distances of ∼10 20 m).
As most team sports require athletes to regularly repeat short, high-intensity efforts, interspersed with longer intervals of submaximal exercise, these physiological factors can be broadly described as factors that affect either sprint performance or the ability to recover from maximal or near-maximal efforts (figure 1).
Microglia movements were characterized by long intervals during which the cells moved very slowly interspersed with brief intervals during which they moved more quickly ( Fig. 4A & 4B).
Athletes engaged in these sports are required to repeatedly produce skilful actions and maximal or near-maximal efforts (eg, accelerations, changes in pace and direction, sprints, jumps and kicks), interspersed with brief recovery intervals (consisting of rest or low-intensity to moderate-intensity activity), over an extended period of time (1 2 h).
A reference time course consisting of periods of stimulation interspersed with non-stimulation intervals was created by a "sliding window" [8], [9] of stimulation that cycled repeatedly over the digit surface (Fig. 1).
HIIT refers to brief intervals of vigorous activity interspersed with periods of low activity or rest, and elicits a strong cardiac response compared with moderate continuous exercise [ 12, 13].
Repeated bouts of short-duration, high-intensity exercise interspersed with brief recovery intervals is a hallmark of many invasion games such as Association football, rugby union/league, and field hockey (King et al. 2009; Mohr et al. 2003; Spencer et al. 2004).
Although shorter dives are most common, dives of up to 30 min, generally interspersed with series of shorter surfacings (at 15 to 20 sec intervals), have been recorded.
Interventions prescribing interval training generally took the format of vigorous (rather than high or maximal) intervals lasting 3 4 min interspersed with 2 3 min of active or passive recovery (refer to Table 2 footnotes for details).
For those unfamiliar with the term, high-intensity intervals are just that: bursts of strenuous exercise lasting anywhere from 30 seconds to several minutes, interspersed with periods of rest.
Lots of woods interspersed with huge stretches of water.
