Type 2 diabetes patients find exercise more difficult
All of the women exercised on a stationary bicycle at a low to moderate intensity similar to the work needed to walk one mile in 25 minutes. During the exercise, women reported how difficult it felt while also having blood drawn to test for lactate levels. Those levels are an important measure of effort because they increase in proportion to the level of exertion.And guess what.... eating fruit before exercising makes this worse.
The researchers found significantly higher lactate levels during low to moderate intensity exercise in people with Type 2 diabetes than their counterparts without the disease. They also tended to score higher on the Rating of Perceived Exertion that measures how difficult people rate the exercise.
"Exercise effort is an important barrier to physical activity because it is modifiable," the study said, "and the perception of more intense effort during exercise has been associated with lower levels of usual physical activity."
According to Huebschmann, these findings suggest that common household activities like climbing stairs or carrying groceries would feel more difficult to people with Type 2 diabetes than to their counterparts without diabetes.
Sheesh.
Here's a great one from Denise.
Losing Neutrality: The Neural Basis of Impaired Emotional Control without Sleep
Sleep loss is known as a robust modulator of emotional reactivity, leading to increased anxiety and stress elicited by seemingly minor triggers. In this work, we aimed to portray the neural basis of these emotional impairments and their possible association with frontal regulation of emotional processing, also known as cognitive control of emotion. Using specifically suited EEG and fMRI tasks, we were able to show that sleep deprivation alters emotional reactivity by triggering enhanced processing of stimuli regarded previously as neutral. These changes were further accompanied by diminished frontal connectivity, reduced REM sleep, and poorer performance. Therefore, we suggest that sleep loss alters emotional reactivity by lowering the threshold for emotional activation, leading to a maladaptive loss of emotional neutrality.
Emotional volatility. Sounds familiar for some reason... wish I could remember.... ha.
