Here are parts of a short paper I wrote on the subject while in physical therapy school. It summarizes recent literature on the subject and includes my opinion with some supporting evidence. While not exhaustive, I feel it provides reasonable discussion:
"I understand the desire to continuously participate in one’s sport of choice. Whether it’s simply for enjoyment of the sport, or the need to hone skills for increased playing time, make the team, or earn a scholarship, the reasons for specialization and year round play are justified. According to Ericsson et al1 becoming an expert in a chosen domain requires 10,000 hours of deliberate practice that coincide with periods of biological and cognitive development. Proponents of early specialization argue that children who specialize enhance skill acquisition through deliberate practice, and receive better coaching and training. However, the literature on early specialization and physical benefit is mixed.2 The pros and cons of early specialization varies from sport to sport. Sports where physiological conditioning is important, sport diversification may be as equally effective. Whereas, athletes in highly technical sports may benefit from specialization."
"Since learning about the intricacies of overload, recovery, and injury, in addition to the physiological and psychological components of development, I find myself challenging my initial views favoring early specialization. While I can’t fault an athlete for loving their sport and wanting to participate and improve their skills, there are detrimental aspects with such a high level of participation. Of particular importance to our profession, is the impact of excessive training during musculoskeletal development. During periods of skeletal growth, there is often inflexibility of the muscles and connective tissue as they don’t grow at the same rate of bones. This creates increased stress to joints during loading and increases susceptibility to repetitive trauma. Associated conditions such as osteochondrosis, Osgood-Schlatters’ and Sever’s diseases can occur as a result.3 Nonetheless, it is important to state that while overuse injuries and developmental abnormalities are linked with sports specialization, there is no direct evidence stating specialization as a cause.2"
"Perhaps more troubling is the psychological detriments early specialization may have on youth athletes. Some negative psychological factors associated with early sports specialization include burnout, loss of motivation, increased stress and pressure, social isolation, missing childhood moments, and decreased sport and fitness participation in adulthood.4 On top of the potential psychological detriments, there are also significant costs and time demands associated with specialization."
"So should youth athletes not focus on a specific sport? Jayanthi et al5 argue that specialization is necessary for elite skill development and that for most sports specialization should begin in late adolescence. Delaying specialization until late adolescence should reduce the risk for injury and psychological stress. To expand, other research suggests early diversification then subsequent specialization of a sport of choice in late adolescence. Supporters of diversification argue that athletes who experience many sports early are not at a disadvantage to those who specialize. Additionally, other sports may augment the physical and cognitive skills needed for their sport of choice.3 Nyland6 agrees that sports specialization should be taken with caution, but argue that late adolescence may be too late to specialize and advocates that athletes should monitor volume to avoid overuse injuries. As discussed earlier, the nature of the sport also has a bearing on what is most suitable."
"While the literature is not in favor of early sports specialization, I don’t necessarily think it should be demonized. The primary problem with early specialization and adverse effects is the disconnect between coaches, parents, and the athlete.6 For example, athletes on multiple teams will have different practice and play schedules with no regard for each other. One can see how this easily leads to excessive training volume. Additionally, there are parents and coaches who may be unaware of proper nutrition, training progression, and proper recovery. The key may not be to curb early specialization, but to shift training volume and recovery into appropriate ranges. Not only while this help the physical and psychological well-being of developing athletes, it may also improve performance! Physical therapists have a role in this education through advocacy and communication with individual athletes, parents, and coaches. Ultimately the goal for youth athletes should be to prevent overuse injuries in any sport involvement, specialized or diverse, through evidence-based progression and recovery."
