This systematic review and meta-analysis of randomized controlled trials suggests that aerobic exercise may reduce cardiovascular disease risk as predicted by some lipid biomarkers and ratios, when it is prescribed as treatment or prevention.
- The study conducted a meta-analysis of RCTs comparing the effects of at least 12 weeks of cardio achieving a minimum aerobic intensity (> 40% V'O2MAX), against no exercise on apolipoproteins, lipoprotein sub-fractions, associated ratios and lipid ratios...
...in sedentary adults free of chronic diseases other than the CVD risk factors comprising metabolic syndrome.
- It was found that aerobic exercise is likely to improve TC/HDL-C, LDL-C/HDL-C and Apo B100/Apo A1 ratios, as well as Apo B100 and VLDL values.
Estimating the Effect of Aerobic Exercise Training on Novel Lipid Biomarkers: A Systematic Review and Multivariate Meta-Analysis of Randomized Controlled Trials (open access)
In this one, 4 weeks of HIIT improved macrovascular function, as measured by flow-mediated dilation, but 2 weeks of detraining were enough to reverse the improvements induced by the training back to pre-training values in adolescent boys aged 12–14 years.

This review provides an update to the position stand of the International Society of Sports Nutrition (ISSN), integrating current literature on energy drinks and energy shots in exercise, sport, and medicine.
This is extremely extensive, or should I say exhaustive.
I can only include *some* of the concluding keypoints:
- Energy drinks can enhance acute aerobic exercise performance, largely influenced by the amount of caffeine (> 200 mg or >3 mg∙kg bodyweight [BW−1]) in the beverage.
This systematic review and meta-analysis suggests that even though the Range Of Motion (ROM) during resistance training appears to have at most a modest impact on musculoskeletal function and morphology, different ROMs may be appropriate for different goals.
- ROM during RT appears to have at most a modest impact on outcomes of interest (strength, muscle size, body composition, power, or sport performance proxies).
- The impact of ROM was found to be trivial to small, favoring a full or long ROM compared to partial ROM.
This one in rats suggests that long-term exercise preserves pancreatic islet structure and β-cell mass through may directly or indirectly attenuate islet fibrosis and protects the pancreatic islets through anti-inflammatory and anti-fibrotic actions.
- After 60 weeks (~14 human years) of exercise, it was found to lead to a 68% and 45% reduction in islet fibrosis in the normal and high-fat diet groups and was correlated with a lower serum blood glucose.
- Fibrotic islets were characterized by irregular shapes and substantial loss of β-cell mass, but these were reduced in the exercise groups.
This meta-analysis of large prospective studies suggests dose-dependent associations between increased non-occupational physical activity and a wide range of mortality, cardiovascular disease and cancer outcomes.
- In general, higher activity levels were associated with lower risk of all outcomes.
- Evidence of dose-dependent associations between increasing non-occupational physical activity and a wide range of mortality, CVD and cancer outcomes was observed.
