    Objective: The purpose of this study was to evaluate the muscle activation patterns of lower limb muscles during 90-second trials at randomly assigned workloads (0 and 100 W) with a constant cadence (60 rpm) in young and older healthy adults. Methods: Twelve healthy, male, novice cyclists classified by age into two groups of young and older. Electromyographic (EMG) data were recorded from rectus femoris (RF), biceps femoris (BF), tibialis anterior (TA), and gastrocnemius medialis (GT). Joints kinematics was also recorded simultaneously. A performance index (PI) was developed to evaluate the characteristics of muscle recruitment between workloads. Results: EMG duration and peak magnitude increased significantly with increased workload in RF and BF in both groups. PI Values indicated that BF and RF had .. View More»
