Abstract

It has been hypothesized that one mechanism through which physical activity provides benefits to cognition and mood is via increasing brain‐derived neurotrophic factor (BDNF) concentrations. Some studies have reported immediate benefits to mood and various cognitive domains after a single session of exercise. This meta‐analysis sought to determine the effect of a single exercise session on concentrations of BDNF in peripheral blood, in order to evaluate the potential role of BDNF in mediating the beneficial effects of exercise on brain health. MEDLINE, Embase, PsycINFO, SPORTDiscus, Rehabilitation & Sports Medicine Source, and CINAHL databases were searched for original, peer‐reviewed reports of peripheral blood BDNF concentrations before and after acute exercise interventions. Risk of bias within studies was assessed using standardized criteria. Standardized mean differences (SMD s) were generated from random effects models. Risk of publication bias was assessed using a funnel plot and Egger's test. Potential sources of heterogeneity were explored in subgroup analyses. In 55 studies that met inclusion criteria, concentrations of peripheral blood BDNF were higher after exercise (SMD = 0.59, 95% CI: 0.46–0.72, P < 0.001). In meta‐regression analysis, greater duration of exercise was associated with greater increases in BDNF. Subgroup analyses revealed an effect in males but not in females, and a greater BDNF increase in plasma than serum. Acute exercise increased BDNF concentrations in the peripheral blood of healthy adults. This effect was influenced by exercise duration and may be different across genders.

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

  • Dose is an essential factor for triggering neurobiological processes, such as release of neurotrophins including BDNF, which in turn lead to neuroplastic changes.

    “Since dose is an essential factor for triggering neurobiological processes (e.g., release of neurotrophins such as BDNF; Dinoff et al., 2017), which in turn lead to neuroplastic”
  • Neurobiological processes triggered by exercise, such as release of neurotrophins like BDNF, lead to neuroplastic and cognitive changes.

    “for triggering neurobiological processes (e.g., release of neurotrophins such as BDNF; Dinoff et al., 2017), which in turn lead to neuroplastic and cognitive changes (Cotman et al., 2007; Voss et al., 2011, 2013a; Lucas et al., 2015; Zimmer et al., 2015; Basso and Suzuki, 2017; Stimpson et al., 2018)”
  • Increased BDNF concentrations were observed after longer bout durations, more than 30 minutes versus less than 30 minutes, in those with higher cardiorespiratory fitness, and the findings were selective to males, although 75% of participants across studies were male.

    “Findings further indicated that increased BDNF concentrations were observed following longer bout durations (>30 min relative to <30 min) in those who had higher cardiorespiratory fitness (i.e., > VO2 peak), and that the findings were selective to males (although 75% of participants across studies were male) (74).”
  • A meta-analysis indicated higher concentrations of peripheral blood BDNF after an acute bout of physical activity, for both aerobic and resistance bouts.

    “However, a meta-analysis examining a blood-based biomarker has indicated higher concentrations of peripheral blood BDNF following an acute bout of PA (both aerobic and resistance bouts).”

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.
