Intriguing results in the science of fitness, nutrition and sports this past week. Trainers from all backgrounds will find something their clients might find helpful including the athletes, the geeks, those training elderly clients or people with back pain.
Here are the highlights:
How diet affects tumors
A new study finds cutting off cells’ supplies of lipids can slow the growth of tumors in mice
Researchers analyzed ketogenic and calorically restricted diets in mice, revealing how those diets affect cancer cells and offering an explanation for why restricting calories may slow tumor growth.

A diet of essential amino acids could keep dementia at bay
Consuming Amino LP7, a specific combination of essential amino acids, could inhibit the development of dementia, shows a study from Japan
Protein intake is known to be vital for maintaining brain function in older individuals. Now, using a mouse model of Alzheimer's disease, researchers have shown that the intake of a specific set of amino acids can inhibit the death of brain cells, protect the connections between them, and reduce inflammation, preserving brain function. Their research suggests that this amino acid combination called Amino LP7 can hinder the development of dementia, including Alzheimer's disease.

Back pain common among astronauts offers treatment insights for the earth-bound
Research reviews show back pain affects more than 50% of space travelers
As more people travel into space, experts expect more physicians will see patients with space travel-related pain.

Skin-inspired sensors show how our body moves
Scientists have created wearable, stitchable, and sensitive sensors from flexible polymers and bundles of carbon fibre. Like our skin, these sensors respond to pressure and can measure body position and movement. They could be used to measure disease progress in Parkinson's disease, or sense joint movement in athletes, for example.

Increased consumption of whole grains could significantly reduce the economic impact of type 2 diabetes
Increased consumption of whole grain foods could significantly reduce the incidence of type 2 diabetes and the costs associated with its treatment.

Fat cells found to play a central role in cognitive decline and neurodegeneration
New findings show that fat cells control the systemic response to brain function, causing impairment in memory and cognition in mice. The activation of Na,K-ATPase oxidant amplification loop affects the expression of important protein markers in fat cells as well as in the hippocampus, which can worsen brain function and lead to neurodegeneration.

Researchers evaluate whether lactate sensors can contribute to sports physiology
A recent article says that despite a recent history of contradictory -- and incomplete -- evidence, sports physiology is zeroing in on whether lactate sensor technology can improve performance while preventing injury.

A good night’s sleep may mitigate infant obesity risks
New research suggests that newborns who sleep longer and wake up less throughout the night are less likely to be overweight in infancy.
