Topics range greatly in this week's collection of studies from the world of fitness, nutrition and exercise science. Whether that's proof of aerobic exercise positively affecting cognitive function in older adults, interesting theory of the evolution of taste or how considering emotions when trying to help overweight and obese people improves their chances to succeed in improving their heart health, all personal trainers can find something their client might find useful.
Here are the highlights:
Memory biomarkers confirm aerobic exercise helps cognitive function in older adults
Study conducted on older adults with familial and genetic risk for Alzheimer's disease
Until now, systemic biomarkers to measure exercise effects on brain function and that link to relevant metabolic responses were lacking. A study shows a memory biomarker, myokine Cathepsin B (CTSB), increased in older adults following a 26-week structured aerobic exercise training. The positive association between CTSB and cognition, and the substantial modulation of lipid metabolites implicated in dementia, support the beneficial effects of exercise training on brain function and brain health in asymptomatic individuals at risk for Alzheimer's.

Persistence pays off in the human gut microbiome
The human gut microbiome is a complex community of trillions of microbes that are constantly interacting with each other and our bodies. It supports our wellbeing, immune system and mental health -- but how is it sustained?

The evolution of good taste
Does evolution explain why we can't resist a salty chip? Researchers found that differences between the elemental composition of foods and the elemental needs of animals can explain the development of pleasing tastes like salty, umami and sweet.

Obesity and hypertension: Researchers discover novel mechanisms
Researchers have succeeded for the first time in demonstrating the role of hypothalamic astrocytes in obesity-related hypertension. In addition, they showed that the hormone leptin is involved in the increase of blood vessels in the hypothalamus of obese mice, contributing of hypertension.

Link found between gut microbes and stroke
Findings lay the groundwork for new stroke treatments, prevention strategies
New findings show that the gut microbiome impacts stroke severity and functional impairment following stroke. The results lay the groundwork for potential new interventions to help treat or prevent stroke.

Focus on emotions is key to improving heart health in people living with obesity
People living with obesity who attended a non-judgemental and personalized lifestyle modification program improved their cardiovascular and mental health during just 10 weeks, according to a new study. Participants lost weight and achieved benefits in anxiety and depression and physical measurements including blood pressure.
