Adding Intermittent Vibration to Varied-intensity Work Intervals: No Extra Benefit
Int J Sports Med DOI: 10.1055/a-1812-7600Varied-intensity work intervals have been shown to induce higher fractions of
maximal oxygen uptake during high-intensity interval training compared with
constant-intensity work intervals. We assessed whether varied-intensity work
intervals combined with intermittent vibration could further increase
cyclists’ fraction of maximal oxygen uptake to potentially optimise
adaptive stimulus. Thirteen cyclists (V̇O2max:
69.7±7.1 ml·kg−1·min−1)
underwent a performance assessment and two high-intensity interval training
sessions. Both comprised six 5-minute varied-intensity work intervals within
which the work rate was alternated between 100% (3×30-second
blocks, with or without vibration) and 77% of maximal aerobic power
(always without vibration). Adding vibration to varied-intensity work intervals
did not elicit a longer time above ninety percent of maximal oxygen uptake
(415±221 versus 399±209 seconds, P=0.69).
Heart rate- and perceptual-based training-load metrics were also not affected
(all P≥0.59). When considering individual work intervals, no
between-condition differences were found (fraction of maximal oxygen uptake,
P=0.34; total oxygen uptake, P=0.053; mean
minute ventilation, P=0.079; mean heart rate,
P=0.88; blood lactate ...
