Methods— Data were extracted and filtered from electronic databases PubMed (MEDLINE), CINAHL, Embase, PsycINFO, and Scopus. Intervention effects were represented by Hedges’ g and combined into pooled effect sizes using random effects models. Heterogeneity was evaluated using the Chi-squared (Q) and I-squared statistics.
Results— Five studies met inclusion criteria, representing data from 182 participants. The primary analysis produced a positive overall effect of aerobic exercise on cognitive performance (Hedges’ g [95% confidence interval]= 0.42 [0.007–0.77]). Effects were significantly different from zero for aerobic interventions combined with other physical activity interventions (Hedges’ g [CI] =0.59 [0.26 to 0.92]), but not for aerobic interventions alone (P= 0.40). In specific subdomains, positive moderate effects were found for global cognitive function (Hedges’ g [CI] =0.79 [0.31 to 1.26]) but not for attention and processing speed (P=0.08), executive function (P= 0.84), and working memory (P=0.92).
Conclusions— We determined that aerobic exercise combined with other modes of training produced a significant positive effect on cognition in adults after stroke in the subacute and chronic phases. Our analysis supports the use of combined training as a treatment option to enhance long-term cognitive function in adults after stroke. Further research is needed to determine the efficacy of aerobic training alone.
Health and Wealthness is a podcast where your hosts, Emily Weigel and Hanaa Khan discuss pressing and trending topics about health and wealth that everyone should know about. Our first four episodes focus on the opioid crisis. Both the science and healthcare sides. We then go on to talk about burnout and mental health in a conversational episode.
The purpose of this study was to examine the validity of a modified Assisted Cycling Therapy bicycle for improving depression in children with Down Syndrome (DS). Seven participants completed 2x/week for 8 weeks, 30 minutes at a time of ACT, in which participants’ voluntary pedaling rates were augmented via the bicycle motor, ensuring that they were pedaling at a rate greater than their self-paced rate. Depression was measured using a modified version of the Children’s Depressive Inventory, called the CDI-2. Our study demonstrated that the scores from the CDI-2 decreased, demonstrating less depressive symptomatology after the conclusion of the 8 week intervention. Our results were interpreted via our model of the mechanisms involved in influencing the success of ACT. Future research would include a greater sample size, a more relevant measure of depressive scores, and a consistent data collection environment. However our initial pilot study showed promising results for improving mental health in children with DS.
Our current understanding of the mitochondrial genome was revolutionized in 2015 with the discovery of short open reading frames (sORFs) that produced protein products called mitochondrial-derived peptides (MDPs). Interestingly, unlike other proteins produced by the organelle, these MDPs are not directly involved in the electron transport chain but rather serve the role of metabolic regulators. In particular, one of these peptides called MOTS-c has been shown to regulate glucose and fat metabolism in an AMPK-dependent manner. With its capacity to enter the mitochondria and impact gene expression, MOTS-c has also displayed the ability to increase aerobic exercise performance by triggering elevated synthesis of the HO-1 antioxidant. Overall these findings position MOTS-c as a promising treatment for metabolic diseases as well as a potential dietary supplement to boost ATP availability.
