Comparative StudyGender differences in the fatigability of the inspiratory muscles.
The purpose of the present study was to determine whether gender differences are present in the fatigability of the inspiratory muscles of humans. Based on evidence for a gender difference in the oxygen cost of breathing, we hypothesized that females would result in a greater magnitude and/or faster rate of inspiratory muscle fatigue than males. ⋯ The results provide some evidence that the fatigability of the inspiratory muscles is different between genders. Females demonstrated a slower rate of fatigue during resistive breathing than males, a finding independent of muscle strength.

An analysis of maximum vehicle G forces and brain injury in motorsports crashes.
Traumatic brain injury from automobile crashes is a major source of trauma deaths. The investigation of crashes to understand factors of occupant injuries is an established practice. Our objective was to evaluate the association between vehicle G forces (G) sustained on impact and brain injury in motor sports crashes. ⋯ Findings were that IRL car crashes with peak vehicle G > or = 50 were associated with the development of traumatic brain injuries.

Case ReportsCase report of exertional rhabdomyolysis in a 12-year-old boy.
Exertional rhabdomyolysis has been well characterized, and many case reports exist. No cases of exertional rhabdomyolysis in young healthy children (preteen) have been published. ⋯ Although exertional rhabdomyolysis is rare in young children, it can occur when excessive exercise is spurred on by an adult.
