Cycling gross efficiency (GE) is one of the main factors which define cycling performance, however, the role of muscular strength and muscle tendon-unit mechanical properties in GE variations between elite and amateur cyclists and gender remain unclear. Thus, the aim of this study is to evaluate the role every measured performance variable on cycling efficiency in different groups (male professional vs. male amateur vs. female cyclists). The study’s findings will help us identify the key factors to focus on cycling training for improved performance. Forty-five cyclists (elite male cyclists n= 15, amateur male cyclists n= 15 and trained female cyclists, n= 15) voluntarily participated in this study. Testing procedure was divided in two days. First day, anthropometric measures, TMG for vastus lateralis muscle and VO2max test were performed, while in the second day, passive resistive torque (PRT) and maximal voluntary isometric contraction (MVIC) for knee extensors were performed using Biodex dynamometer, followed by GE test in ergometer at 120W for female and 160W for males and three different intensities from VO2max test (45%, 55% and 65%). Results showed muscle stiffness is the main predictor for amateur male cyclists at each intensity; GE45% (R2 = 0.34), GE55% (R2 = 0.58), GE55% (R2 = 0.49). Main predictor parameters for elite male cyclists were stiffness and MHC-I% for GE45% (R2 = 0.51; R2 = 0.70); GE55% (R2 = 0.52; R2 = 0.63); and just stiffness for GE65% (R2 = 0.70). Main predictors parameters for female cyclists are PPO at GE45% (R2 = 0.32) and stiffness at GE55% and GE65% (R2 = 0.44; R2 = 0.43).
