1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

purposeThe present study examined the effect of reducing sprint interval training (SIT) work-interval duration on increases in maximal and submaximal performance.

methodsSubjects (n = 36) were assigned to one of three training groups: endurance training (ET; 60 min per session for weeks 1-2, increasing to 75 min per session for weeks 3-4), or sprint interval training consisting of either repeated 30 (SIT 30) or 15 (SIT 15) second all-out intervals (starting with 4 bouts per session for weeks 1-2, increasing to 6 intervals per session for weeks 3-4). Training consisted of cycling 3 times per week for 4 weeks.

resultsWhile there was a significant main effect of training on VO₂peak such that VO₂peak was elevated post-training, no significant difference was observed in the improvements observed between groups (ET ~13%, SIT 30-4%, SIT 15-8%). A significant main effect of training was observed such that lactate threshold and critical power were higher during post-testing across all groups (p < 0.05). There was a main effect of training (p < 0.05) on Wingate peak power with no differences observed between groups at post-training.

conclusionsTogether, these results indicate that reducing SIT work-interval duration from 30 to 15 s had no impact on training-induced increases in aerobic or anaerobic power, or on increases in lactate threshold (absolute) and critical power.
