Exercise Meaningful in Having Good Mental Health

In this cross-sectional study, we analysed data from 1 237 194 people aged 18 years or older in the USA from the 2011, 2013, and 2015 Centers for Disease Control and Prevention Behavioral Risk Factors Surveillance System survey. We compared the number of days of bad self-reported mental health between individuals who exercised and those who did not, using an exact non-parametric matching procedure to balance the two groups in terms of age, race, gender, marital status, income, education l...

 Evidence on Creatine

Strong scientific evidence for this use Enhanced muscle mass / strength: Several high-quality studies have shown an increase in muscle mass with creatine use. However, some weaker studies have reported mixed results. Overall, the available evidence suggests that creatine does increase lean body mass, strength, and total work. Future studies should include the effect of individual differences such as fitness levels, sex, and age. Unclear scientific evidence for this use Athletic performance...

 Exercise Rejuvenates the Body

As noted earlier, mitochondrial degradation is a primary culprit in dwindling muscle mass. But recent evidence indicates that exercise can slow down this effect. According to Mark Tarnopolsky, a professor of pediatrics and medicine at McMaster University in Hamilton, Ontario, resistance training activates a muscle stem cell called a satellite cell. In a physiological process known as ‘gene shifting,' these new cells cause the mitochondria to rejuvenate. Tarnopolsky claims that after six mon...

 Exercise with your Children

This rise in pediatric obesity is painful to hear in the brain science community, especially because we know so much about the relationship between physical activity and mental acuity. Exercise—especially aerobic exercise—is fanastic for the brain, increasing executive function scores anywhere from 50 percent to 100 percent. This is true across the life span, from young children to members of the golden-parachute crowd. Strengthening exercises do not give you these numbers (though ther...
