Article Synopsis
- The study focuses on the rising rates of obesity and the challenges young adults face with dietary recommendations during the transition to higher education, a time often associated with weight gain.
- Researchers explored whether providing personalized dietary and exercise advice based on individual genotypes would enhance healthy eating motivation among young adults aged 18-25.
- Findings revealed that genotype-based personalized advice did not significantly influence healthy eating motivation compared to non-genotype advice or no advice, suggesting this approach may not be effective in preventing obesity in this demographic.*
Purpose: The effects of low-intensity exercise, heat-induced hypo-hydration and rehydration on maximal strength and the underlying neurophysiological mechanisms are not well understood.
Methods: To assess this, 12 participants took part in a randomised crossover study, in a prolonged (3 h) submaximal (60 W) cycling protocol under 3 conditions: (i) in 45 °C (achieving ~ 5% body mass reduction), with post-exercise rehydration in 2 h (RHY2), (ii) with rehydration across 24 h (RHY24), and (iii) a euhydrated trial in 25 °C (CON). Dependent variables included maximal voluntary contractions (MVC), maximum motor unit potential (M), motor evoked potential (MEP) amplitude and cortical silent period (cSP) duration.
The neurobiology and neurochemistry of bipolar disorder and its different phases are poorly understood. This study investigated metabolite abnormalities in both unmedicated bipolar depression as well as mania using 2D 1H magnetic resonance spectroscopy imaging (MRSI). MRSI data were obtained from 24 unmedicated bipolar disorder (BP) subjects (12 (hypo)manic (BPM)) and 12 depressed (BPD), and 20 closely matched healthy controls.
