In athletes, concussions were followed by changes in hip, knee, and leg stiffness, potentially contributing to post-concussion injuries below the hip.

Modest weight gain was associated with a decreased ability to taste sweet and salty flavors for male college students, but not for females.

People are more motivated to run and can run faster when they are racing with someone they consider a rival (compared to a competition without perceived rivals).

Scientific Reports

In an analysis of 33 NBA playoff series, teams facing elimination were more likely to lose than expected, suggesting that adding extreme pressure does not improve performance.

Active cyclists over 55 years old were more similar to young adults in many measures of immune system performance than less active people their age.

Declines in physical abilities related to aging were apparent in adults as early as their 50s. This suggests that efforts to maintain basic strength and endurance should not wait until later years.
