Table 4: Proposed field-based evaluation protocol for frequent athlete screening and interventions to prevent HIs. Similarly, it is vital to apply specific and individualized exercise prevention interventions to deal with specific impairments (neuromuscular or psychological) captured in structural evaluation. Likewise, effective prevention plans should incorporate adequate exposure to HSR during training [18; 93], strategies to increase athletes' adherence to medical instructions, and strategies for adequate recovery from competition [55; 79]. Finally, it is essential to mention that HI assessment protocols should be incorporated into a more comprehensive protocol that considers the risk factors for the main sports injuries. Although HI is the most prevalent injury [4], other types of injuries represent a considerable percentage of the total injury rate and should not be underestimated [85].
