TL;DR: It is concluded that several genes involved in theMyostatin pathway, but not the myostatin gene itself, are important QTLs for human muscle strength.

TL;DR: Gymnasts have clearly defined adolescent spurts in height, estimated leg length, and sitting height that occur approximately 1 year later and are slightly less intense than in nonathletic adolescent girls.

TL;DR: The amount of variance of adult fitness levels explained increased significantly when other characteristics observed during adolescence entered the regressions or discriminant functions, indicating that in addition to fitness scores, anthropometric dimensions, and skeletal maturation, behavioural characteristics also added significantly to the prediction of adult Fitness levels.

TL;DR: For endomorphy, which represents a relative measure of subcutaneous adipose tissue, the results suggest heritability may be considerably lower than most values reported in earlier studies on adolescent twins, and it may be questioned whether studying the Genetics of BMI will eventually lead to a better understanding of the genetics of fatness, obesity and overweight.

TL;DR: The two-staged fine mapping of a previously identified linkage peak for knee strength on chr12q12-14 is described, and genetic variants in the ACVR1B gene account for genetic variation in human muscle strength are identified.
