Figure 1. S100B Changes after non-contact exertion and sports-related concussion.

Figure 1

A: Absolute (Left) and proportional (right) changes in S100B levels after non-contact exertion among individal athletes. The proportional change is defined as (post-exertion or 3-hour post-SRC S100B – baseline S100B)/baseline S100B (range: −35% to +50%; mean proportional change  = +2.7%). The mean post-exertional S100B concentration (0.071±0.03 µg/L) was not significantly different from mean baseline (0.070±0.03 µg/L, *p = 0.87, Middle). B: Absolute (Left) and proportional (right) changes in S100B levels within 3 hours of SRC among individual athletes. The mean post-SRC S100B concentration within 3 hours of concussion (0.099±0.008 µg/L) was significantly higher than that at baseline (0.058±0.006 µg/L, **p = 0.0002, Middle). Proportional change (right) ranged from −14% to +180%; mean proportional change +81.2%). Munich athletes are designated in red, Rochester athletes in black.
