The participants were tested during two exercises (leg press and knee extension) after two conditions: stretching and control. The data were collected on four days (counterbalanced with a 24-hour rest period). In the stretching condition, the quadriceps muscle was stretched (knee flexion) for three sets of 30 s with 30 s rest intervals. No significant difference was detected for peak force and peak rate of force development during the single- and multiple-joint exercises, regardless of the following interactions: condition (stretching and control) vs. time (pre x post x 10 x 20 x 30 minutes post; P > 0.05) and exercise vs. time (P > 0.05). Additionally, no significant interaction was found for the iEMG activity (condition vs. time; P > 0.05) in the single- and multiple-joint exercises. In conclusion, a small amount of stretching of an agonist muscle (quadriceps) did not affect the peak force, peak rate of force development and EMG activity in older women during single- and multiple-joint exercises. © 2013 Copyright Taylor and Francis Group, LLC.690-698engagingisometric force-time curveperformancewarm-upagedcontrolled clinical trialcontrolled studyelectromyographyexercisefemalehumanjointlegmiddle agedmuscle isometric contractionmuscle strengthphysiologyquadriceps femoris musclerandomized controlled trialstretching exerciseAgedElectromyographyExerciseFemaleHumansIsometric ContractionJointsLower ExtremityMiddle AgedMuscle StrengthMuscle Stretching ExercisesQuadriceps MuscleArtigo10.1080/02640414.2012.746727WOS:000319095200002Acesso restrito2-s2.0-848758580049868835271822421
