Abstract

Skeletal muscle primarily relies on carbohydrate (CHO) for energy provision during high-intensity exercise. We hypothesized that sprint interval training (SIT), or repeated sessions of high-intensity exercise, would induce rapid changes in transport proteins associated with CHO metabolism, whereas changes in skeletal muscle fatty acid transporters would occur more slowly. Eight active men (22 ± 1 yr; peak oxygen uptake = 50 ± 2 ml·kg−1·min−1) performed 4–6 × 30 s all-out cycling efforts with 4-min recovery, 3 days/wk for 6 wk. Needle muscle biopsy samples (vastus lateralis) were obtained before training (Pre), after 1 and 6 wk of SIT, and after 1 and 6 wk of detraining. Muscle oxidative capacity, as reflected by the protein content of cytochrome c oxidase subunit 4 (COX4), increased by ∼35% after 1 wk of SIT and remained higher compared with Pre, even after 6 wk of detraining ( P < 0.05). Muscle GLUT4 content increased after 1 wk of SIT and remained ∼20% higher compared with baseline during detraining ( P < 0.05). The monocarboxylate tranporter (MCT) 4 was higher after 1 and 6 wk of SIT compared with Pre, whereas MCT1 increased after 6 wk of training and remained higher after 1 wk of detraining ( P < 0.05). There was no effect of training or detraining on the muscle content of fatty acid translocase (FAT/CD36) or plasma membrane associated fatty acid binding protein (FABPpm) ( P > 0.05). We conclude that short-term SIT induces rapid increases in skeletal muscle oxidative capacity but has divergent effects on proteins associated with glucose, lactate, and fatty acid transport.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • During exercise, glycolytic flux in the skeletal muscles can be dramatically increased.

    “During exercise, glycolytic flux in the skeletal muscles can be dramatically increased [127,128].”
  • This study extends previous literature showing beneficial effects of high-intensity interval training by showing that sprint number and duration can be substantially reduced whilst still maintaining positive effects.

    “This study extends the previous literature showing the beneficial effects of HIT (Burgomaster et al. 2007;Babraj et al. 2009;Richards et al. 2010;Whyte et al. 2010;Rakobowchuk et al. 2008;Trilk et al. 2010) by showing that the sprint number and duration can be substantially reduced whilst still maintaining positive effects.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
