6 sekunders all out sprint på cykelergometer kan måle hvor høj den maksimale kraft vedkommende kan udføre.

Hvad måler testen?

  • Peak Power Output (watt) (PPO) - Den højeste kraft som gerne skulle måles i løbet af de første 5 sekunder.
  • Cadence peak (RPM)

Gentagen 6 sekunders test

Ved at gentage testen kan man måle den anaerobe kapacitet; altså evnen til at genopbygge sine CrP-depoter og ATP-depoter rigtig hurtigt.

Testen laves 5 x 6 sekunder, hvor pausen er 24 sekunder så man kan restarte testen hver 30’e sekund.

Testen kan måle følgende:

  • Samlede arbejde i perioden
  • Faldet i kraft over de fem sprints

Det må forventes at power falder hen over de 5 sprints.

Peak power output during a 5x6 sec repeated-sprint cycling test performed in the morning and evening. Note that in the evening, peak power was higher during the first sprint, but not different in the latter sprints, which produced a higher calculated sprint decrement (indicated by *) [modified from Racinais et al.[41]].

(Girard 2011)

Som det ses her, så ville man med fx 2 minutters pause i højere grad kunne genopbygge CrP og ATP-depoterne og kunne køre all out.

Graph showing the effects of rest duration on maximal 4 sec, cycle sprint performance. Intermittent sprints were performed every 2 min,[19] whereas repeated sprints were executed every 30 sec.[20] * Significantly different from sprint 1 in the repeated-sprint condition.

Når sprints gentages vil andelen af det aerobe arbejde i sprinten være relativt højere hen over de fem sprints.

Changes in metabolism during (a) the first and (b) the last sprint of a repeated-sprint exercise. [55,62,93] Note that the area of each circle represents the total absolute energy used during each sprint. ATP = adenosine triphosphate; PCr = phosphocreatine.

As sprints are repeated, there is an increase in the aerobic contribution to individual sprints. The dashed line represents the maximal oxygen uptake ( . VO2max) [adapted from McGawley and Bishop [95]]. AOD= accumulated oxygen deficit; . VO2= oxygen uptake
