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

backgroundHigh-intensity interval training (HIT) does not burn fat during exercise. However, it significantly reduces visceral adipose after long-term training. The underlying mechanism may be related to the elevation of fat consumption during the post-exercise recovery period, which is regulated by the hypothalamus-adipose axis. Lactate is a hallmark metabolite of high-intensity exercise, which could mediate significant neuroplasticity through the brain-derived neurotrophic factor (BDNF) pathway. However, whether HIT could enhance hypothalamus activity and adipose catabolism in the recovery period remains to be elucidated. Also, it is worth exploring whether adding lactate administration to prolonged, continuous submaximal aerobic training (AT) could simulate HIT-induced neuroplastic effects and fat loss.

methodsFirst, we compared the influence of 4-week HIT and aerobic training (AT) on the electrophysiology of the ventromedial hypothalamus (VMH), which is deeply involved in the regulation of lipolysis, as well as the 24-hour excess post-exercise oxygen consumption (EPOC), the fat oxidation rate and lipolysis. To further confirm whether excess lactate during AT could reproduce the effect of HIT, we also observed the effects of lactate infusion during AT (AT + Lac) on neuroplasticity and metabolism.

resultsFour-week HIT induced higher BDNF expression and a higher neuronal spike firing rate in VMH than AT, accompanied by elevated EPOC, fat oxidation and visceral fat lipolysis. AT + Lac and HITT could induce similar hypothalamic and metabolic changes. However, power spectral density analysis of local field potentials (LFPs) showed that the AT + Lac group was affected in fewer frequency bands than the HIT group.

conclusionHIT-induced reduction of visceral fat was accompanied by increased VMH activity. Adding lactate administration to AT could partially reproduce hypothalamic plasticity and the metabolic effects of HIT. However, different band changes of LFPs implied that the neuronal subpopulations or pathways influenced by these two methods were not entirely consistent.
