Relationship between quadriceps muscle fiber architecture and lunges performance

The purpose of this research was to ascertain the relationship between architectures lower body muscles and lunges performance. Thirty recreationally active, untrained males (mean age: 17±1.25 years) were recruited participated in two testing sessions: anthropometrics muscle architecture, one-repetition maximum (RM) test. B-mode ultrasonography used assess thickness, pennation angle, fascicle length vastus lateralis (VL), medialis (VM), rectus femoris (RF). 1RM performance estimated using multiple-RM testing. studied correlation analysis. Overall, positively correlated with thickness all muscles. Pennation on other hand, shown be inversely associated results suggested that having a thicker, longer length, angle quadriceps is important for improving performance, which one most specific motions strength development enhanced
