Running fatiguing protocol affects peak torque joint angle and peak torque differently in hamstrings vs. quadriceps

Sport Sciences for Health, 2018
The aim of the current study was to investigate the effects of a running fatiguing protocol on the peak torque joint angle and the peak torque in hamstrings vs. quadriceps. Twenty-one male runners underwent a running fatiguing protocol consisting of 40 min at a speed corresponding at first ventilatory threshold. Before and after the fatiguing protocol,

Choice of electrical motor and transmission in mechatronic applications: The torque peak

Mechanism and Machine Theory, 2011
This paper deals with the effect of the torque peak on the choice of electrical motor and transmission suitable for moving a joint. We propose a method that allows us to explain the general form of the resolving diagram and to identify the load conditions that are directly responsible for it.

The Effect of Extraneous Movements on Peak Torque and Constant Joint Angle Torque-Velocity Curves

Journal of Orthopaedic & Sports Physical Therapy, 1996
During isokinetic knee testing, some subjects flex the trunk and contralateral knee during knee extension and the trunk and contralateral knee during knee flexion. This investigation assessed the effect of these extraneous movements on peak and constant joint angle torque (15 degrees below horizontal).

Effects of Warm-up on Peak Torque, Rate of Torque Development, and Electromyographic and Mechanomyographic Signals

Journal of Strength and Conditioning Research, 2012
The purpose of this study was to determine if an active warm-up affects peak torque (PT), rate of torque development (RTD), and the electromyographic (EMG) and mechanomyographic (MMG) signals. Twenty-one men (mean age ± SD: 24.0 ± 2.7 years) visited the exercise physiology laboratory on 2 occasions.

Maximal peak torque as a predictor of angle-specific torques of hamstring and quadriceps muscles in man

European Journal of Applied Physiology and Occupational Physiology, 1991
This study assessed the relationship between the isokinetic peak torque (PT) (speed of movement 1.05 and 3.14 rads-1) and the angle-specific torques (ASTs) at 0.26 and 1.31 rad of knee flexion in multiple contractions of the quadriceps and hamstrings in 70 individuals with a chronic anterior cruciate ligament (ACL) insufficiency and 78 individuals with

Peaked-MMF smooth-torque reluctance motors

IEEE Transactions on Energy Conversion, 1990
The authors investigate the steady-state torque characteristics of reluctance motors with nonsalient stator punchings, but with peaked rotating magnetomotive forces (MMFs). The torque calculation includes the effects of saturation and fringing and groove fluxes.

Implant micromotion is related to peak insertion torque and bone density

Clinical Oral Implants Research, 2009
AbstractObjectives: Measuring peak insertion torque in relation to different bone densities, the present study seeks to determine whether micromotion at the interface is related to primary stability achieved by increasing insertion torque.Material and methods: A total of 120 Ti‐Bone implants were placed in fresh bovine bone samples representing three

Effects of stretching and fatigue on peak torque, muscle imbalance, and stability

The Journal of Sports Medicine and Physical Fitness, 2018
The present study examined the acute effects of hamstrings stretching and fatigue on knee extension and flexion peak torque (PT), hamstrings to quadriceps (H:Q) ratio, and postural stability.Seventeen women (mean±SD age=21.8±2.1 years; body mass=63.0±10.5 kg; height=164.7±6.2 cm) and eighteen men (25.8±4.6 years; 83.6±13.2 kg; 175.3±6.0 cm) took part ...

Fatigue affects peak joint torque angle in hamstrings but not in quadriceps

Journal of Sports Sciences, 2014
Primary aim of this study was to investigate peak joint torque angle (i.e. the angle of peak torque) changes recorded during an isokinetic test before and after a fatiguing soccer match simulation. Secondarily we want to investigate functional Hecc:Qconc and conventional Hconc:Qconc ratio changes due to fatigue.
