The ACTN3 R577X (rs1815739) genotype has been associated with athletic status and muscle phenotypes, although not consistently. Our objective was to conduct a meta-analysis of the published literature on athletic status and investigate its associations with physical capability in several new population-based studies. Relevant data were extracted from studies in the literature, comparing genotyp...

BACKGROUND Low-volume high-intensity interval training (HIT) appears to be an efficient and practical way to develop physical fitness. OBJECTIVE Our objective was to estimate meta-analysed mean effects of HIT on aerobic power (maximum oxygen consumption [VO(2max)] in an incremental test) and sprint fitness (peak and mean power in a 30-s Wingate test). DATA SOURCES Five databases (PubMed, ME...

A plethora of research has examined bilateral and reciprocal concentric strength relationships of the thigh musculature in a variety of athletic populations. However, little research has reported strength values of the trunk and hip musculature. Thus, the purpose of this investigation was to examine concentric and eccentric strength of the trunk and hip flexor and extensor muscle groups in fema...
