Coding: n/N = number of significant associated relationships divided by total number of relationships investigated. The number of relationships is reported with the study reference number in brackets
Data removed from univariate analyses’ data synthesis due to poor methodological quality and/or high risk of bias included the following: body composition measures (3 relationships [85]), muscular strength (2 relationships [65]), muscular endurance measures (2 relationships, [65]), and coordination measures (1 relationship [71]). Data removed from multivariate analyses’ data synthesis due to poor methodological quality and/or high risk of bias included the following: balance measures (1 relationship [71], 1 relationship [88]), body composition measures (1 relationship [88], 2 relationships [71]), coordination measures (5 relationships [71]), flexibility (1 relationship [88], 2 relationships [71]), and muscular strength measures (3 relationships [88])
