OBJECTIVE
The purpose of the study was to determine whether a performance difference exists between baseball players with "same" (right-right) and "crossed" (right-left) hand-ocular dominance.
DESIGN
A cohort study design was used.
PARTICIPANTS
Four hundred and ten major and minor league members of the Los Angeles Dodgers professional baseball team.
INTERVENTION
Measurement of ocular dominance.
MAIN OUTCOME MEASURES
Batting average and earned run average (ERA).
RESULTS
Same/crossed dominance (with P values in parentheses) are as follows: Batting averages: major league-0.271/0.251 (0.20); minor league-0.274/0.270 (0.57); ERA: major league-3.34/3.56 (0.66); minor league-4.00/4.20 (0.54).
CONCLUSIONS
Hand-ocular dominance patterns do not have an effect on batting average or ERA.
目的
本研究的目的是确定具有“相同”（右-右）和“交叉”（右-左）手眼优势的棒球运动员之间是否存在表现差异。
设计
采用队列研究设计。
参与者
洛杉矶道奇队职业棒球队的410名大联盟和小联盟成员。
干预措施
测量眼优势。
主要观察指标
击球率和自责分率（ERA）。
结果
相同/交叉优势（括号内为P值）如下：击球率：大联盟-0.271/0.251（0.20）；小联盟-0.274/0.270（0.57）；自责分率：大联盟-3.34/3.56（0.66）；小联盟-4.00/4.20（0.54）。
结论
手眼优势模式对击球率或自责分率没有影响。
