Over the last 10 years, there’s been a wide-spread emphasis on “high intensity interval training” to improve conditioning in team sport athletes.
Recently, there’s been more attention paid to the importance of repeat sprint ability (i.e. clustered maximum efforts with incomplete rest before longer periods of lower intensity activity or complete rest), either as the predominant characteristic of sport or as a key characteristic during critical moments of competition.
Unfortunately, a byproduct of these trends is that the benefits of aerobic training have been either largely overlooked or actively dismissed.
Short sprints rely heavily on the PCr (Phosphocreatine) system as an energy source. One of the major limiting factors to repeat sprint ability is the resynthesis of PCr, which is depleted from max efforts lasting more than few seconds (or short efforts repeated within condensed time periods…like a typical hockey shift).
Aerobic training is one of the primary methods of improving PCr resynthesis rates.
Below is a quote from a paper I reference often:
“High-intensity interval training (6–12·[2 minutes at ~100% VO2max:1minute rest]), can significantly improve PCr resynthesis during the first 60 seconds following high-intensity exercise. In contrast, no changes in the rate of PCr resynthesis have been reported following interval (8·[30 seconds at ~130% VO2max:90seconds rest]), or intermittent-sprint training (15·[6-second sprint: 1-minute jog recovery]), or training involving repeated, 30-second, all-out efforts (4–7·[30 seconds ‘all-out’: 3–4 minutes rest]).“
While the authors use “high-intensity interval training” to describe the 6-12 x 2:00/1:00 interval, this is not a method commonly used by those relying on high intensity conditioning (the later examples in the quote are more representative).
The point here is that even if your goal is SOLELY to support maximum speed efforts, aerobic training plays a KEY role in allowing the athlete to repeat those outputs.
