Association between Lower Body Qualities and Change-of-Direction Performance: A Meta-Analysis

Int J Sports Med DOI: 10.1055/a-2117-9490The aim of the present study is to determine the associations between lower body muscle strength qualities and change of direction (CoD) performance. Three databases were used to perform a systematic literature search up to September 30, 2022. Based on the studies that met the inclusion criteria, we calculated Pearson’s r correlation coefficient to examine the relationships between muscle strength qualities and CoD performance. The quality of the studies included was evaluated by the modified version of the Downs and Black Quality Index Tool. Heterogeneity was determined via the Q statistic and I 2, and Egger’s test was used to assess small study bias. The results revealed that lower body maximal strength (pooled: r=− 0.54, dynamic: r=− 0.60, static: r=− 0.41), joint strength (pooled: r=− 0.59, EXT-ecc: r=− 0.63, FLEX-ecc: r=− 0.59), reactive strength (r=− 0.42) and power (pooled: r=− 0.45, jump height: r=− 0.41, jump distance: r=− 0.60, peak power: r=− 0.41) were negatively and moderately related to CoD performance. To conclude, the results highlight that a number of muscle strength qualities are associated with CoD performance and are pertinent to spec...
