“…Twenty-one studies that measured asymmetries during dry-land tests used statistical tests (e.g., t test, Wilcoxon’s, ANOVA, Mann-Whitney, or multiple regression) to analyze the between-limb differences (Table 1). Twelve studies reported no significant side-to-side differences ( p > 0.05) (6,16,17,32,39,45,47,49,50,72,75,85), whereas 9 showed a significant difference ( p < 0.05) in at least one tested variable (21,43,56,59,60,63,67,83,84). The specific metrics that presented significant interlimb differences included the following: triceps electromyographic activity (reported as a % of maximal voluntary load), shoulder medial and lateral rotation (°), subacromial bursa thickness (mm), scapula-humeral rhythm ratio (°), shoulder extension peak of torque (N.m), shoulder external rotation (°), shoulder isolated and composite internal rotation (°), shoulder total arc of motion (°), power output (W), scapula lateral displacement (cm), scapula retraction peak force (N), and scapula protraction:retraction ratio (N).…”

The objectives of this review were to (a) map the studies analyzing bilateral asymmetries in specific (in-water tests) and nonspecific (dry-land tests) swimming contexts and (b) investigate the effects of interlimb asymmetries on swimming performance. Searches were systematically conducted on 4 databases. Of 768 studies examined, 60 were eligible for the final selection (https://osf.io/46gya). Twenty-eight studies analyzed asymmetries during in-water tests, with asymmetry values ranging from 2.7 to 60.0%, and most studies (n = 18) reported significant between-limb differences (p < 0.05). Asymmetries were also analyzed during dry-land tests in 24 studies, with asymmetry values ranging from 1.1 to 16.6%. Interestingly, most of these studies (n = 12) did not verify any significant between-limb differences (p > 0.05). Eight studies measured asymmetries in both contexts and reported asymmetry values from −24.1–17.4%, with 4 studies finding significant differences between body sides (p < 0.05). Seven of the 60 studies selected investigated the relationship between asymmetries and swimming performance, with 5 reporting no meaningful associations. In conclusion, significant asymmetries in swimming are more evident during in-water than during dry-land tests. In addition, the few studies investigating asymmetries' influence on swimming performance reported that asymmetries rarely impact swimming performance.
