Loprinzi et al.1 conducted an experiment to evaluate the potential link between fitness/endurance and episodic memory performance and if there is influence from the post-exercise recovery period. The impetus for this study sprang from mixed findings in the previous literature on the association of cardiorespiratory fitness with general cognitive performance. Cardiorespiratory endurance/fitness – The ability […]

Behm et al. set out to answer this. The researchers conducted a systematic review (a study of studies) with the objective of comparing the effects of static stretching (SS), dynamic stretching (DS), and proprioceptive neuromuscular facilitation (PNF) on performance, range of motion (ROM) and injury risk. This study includes 125 studies incorporating 270 maximal performance
How does static stretching before exercise effect performance, ROM and injury risk? Read More »
Low back pain is the leading cause of disability worldwide. Exercise helps alleviate back pain, which modality, Progressive aerobic or progressive resistance training is superior? Wewege et al.1 conducted a meta-analysis to compare the differences between progressive aerobic training (PAT) and progressive resistance training (PRT) on the treatment of chronic non-specific low back pain (CNSLBP).
Both aerobic and resistance training improve chronic low back pain Read More »
The following are notes from Layne Norton’s conversation with Rhonda Patrick on the FoundMyFitness podcast. Layne, a Ph.D. in Nutritional Sciences, a professional bodybuilder, and a champion powerlifter mentions these as the key factors for growing muscle: Research1 doesn’t appear to show that exercising to failure produces more hypertrophy than exercising close to failure. This

Trott et al.1 conducted a meta-analysis to study the association between total physical activity (PA) levels and academic performance in adults. Only 6 of the 36 studies included were found to be appropriately homogeneous to be included in the meta-analysis. This meta-analysis found a signficiant association between physical activity and academic performance (objective measures: GPA,
An RCT published by Bloch-ibenfeldt et al.1 set out to explore the long-term effects of heavy resistance training in retirement age adults. 369 participants (61% women, mean age 71 years) were randomized to one year of heavy resistance training (HRT), one year of moderate-intensity resistance training (MIT), and a non-exercising control group (CON). The primary
An interesting randomized control trial (RCT) was published by O’Sullivan et al in the journal of Psychiatry Research and found that two 25 minute resistance exercise training (RET) sessions a week for 8 weeks resulted in significant decreases in reported depressive symptoms when compared to a wait-list control group. Compared to the effect size of
Antidepressant effects of exercise are comparable to ssris Read More »
A recent study1 published in JAMA by Stamatakis et al. set out to answer this question. They conducted a prospective cohort analysis of 22,398 people from the UK biobank accelerometry subsample. They found that compared to those who did not engage in vigorous intermittent lifestyle physical activity (VILPA), just 3.4-3.6 minutes of VILPA was correlated
Mitochondrial health is key to health and disease Skeletal muscle plays an instrumental role in mitochondrial function in both health and disease as it is the most bioenergetically active organ with the highest mitochondrial content. mitochondrial dysfunction has traditionally been linked to type 2 diabetes, it is also a hallmark of multiple diseases, including cardiovascular

Skeletal muscle lipid paradox – “A significant histological finding pertaining to skeletal fat metabolism occurs in physically fit individuals as well as in individuals with T2D, where both populations show an accumulation of intramuscular triglycerides. as both physically fit individuals as well as individuals with T2D are characterized by the presence of a “lipid droplet”
