Clinical Question: Is there a greater predisposition to overuse injury, burnout and decreased career longevity when compared to multi-sport athletes in Major League Baseball (MLB) athletes?
Bottom Line: Multi-sport athletes played in significantly more mean total games (362.8 vs 300.8; P < .01) as well as more mean MLB games (95.9 vs 71.6; P = .04) than single-sport athletes. Single-sport athletes had a significantly higher prevalence of upper extremity injuries compared with multi-sport athletes (136 [36%] vs 55 [50%]; P = .009). Single-sport pitchers also had a higher prevalence of shoulder and elbow injuries (86 vs 27; P = .008) and were more likely to have recurrent elbow injuries (33% vs 17% recurrence; P = .002) compared with multi-sport pitchers.
Points to consider: 746 athletes were included in this study: 240 multi-sport and 506 single-sport. Athletes who participated in 1 or more sports in addition to baseball during high school were considered multi-sport, and athletes who participated in only baseball were considered single-sport athletes.
Takeaway: Compelling stuff. Professional MLB players who participated in multiple sports in high school played in MORE major league games and experienced LOWER rates of injuries.
