Influence of Position on Knee Flexor Peak Torque

Journal of Orthopaedic & Sports Physical Therapy, 1988
The purpose of this study was to determine the influence of position on knee flexor peak torque production. Gravity effect torque and knee flexor peak torque were measured in both supine and prone positions for 20 male and female volunteers between the ages of 22 and 35 years with no history of left lower extremity pathology.

Isokinetic Peak Torque and Work Values for the Shoulder

Journal of Orthopaedic & Sports Physical Therapy, 1989
The purposes of this study were to: a) measure peak torque (PKT) at 60 and 180 degrees /sec of angular velocity and work data at 180 degrees /sec of angular velocity for isokinetic muscular performance during external/internal rotation (ER/IR) and modified abduction/adduction (MOD-AB/AD) tests, b) compare the dominant and nondominant upper extremity ...

Shift of Peak Torque Angle After Eccentric Exercise

International Journal of Sports Medicine, 2008
This study aims to investigate the changes in the mechanical properties of quadriceps muscle following a sub-maximal concentric-eccentric stepping exercise protocol. Twenty-four untrained healthy subjects aged 21.9 +/- 0.55 years were asked to perform a 10-minute stepping exercise where the dominant leg worked eccentrically and the non-dominant leg ...

Acute Effects of Static Stretching on Peak Torque in Women

The Journal of Strength and Conditioning Research, 2004
The purpose of this study was to examine the effects of static stretching on concentric, isokinetic leg extension peak torque (PT) at 60 and 240 degrees.s(-1) in the stretched and unstretched limbs. The PT of the dominant (stretched) and nondominant (unstretched) leg extensors were measured on a calibrated Cybex 6000 dynamometer.

A new method of peak torque reduction with redundant manipulators

IEEE Transactions on Automation Science and Engineering, 1997
A new method aiming at reducing peak torques is developed in this paper for kinematically redundant manipulators. The method considers the contributions of both velocity and acceleration to the joint torque. Instead of minimizing the joint torque or kinetic energy at the current station, the method always uses the current torque to approach an optimum ...

Effects of Stretching on Peak Torque and the H : Q Ratio

International Journal of Sports Medicine, 2008
The purpose of the present study was to examine the acute effects of hamstring and calf stretching on leg extension and flexion peak torque (PT) and the hamstrings-to-quadriceps (H : Q) ratio during maximal, concentric isokinetic muscle actions at 60, 180, and 300 degrees . s (-1) in women.

Peak volitional torques for wrenches and screwdrivers

International Journal of Industrial Ergonomics, 1988
Abstract Effects of grip shape (regular, circular, square, and triangular), wrist orientation (3 for screwdrivers and 7 for wrenches) and duration of repeated exertions on the maximum torque males and females could exert in different postures with 4 wrenches and 4 screwdrivers were investigated experimentally.

Relationship Between Isokinetic Average Force, Average Torque, Peak Force, and Peak Torque of the Knee Extensor and Flexor Musculature [PDF]

Isokinetics and Exercise Science, 1994
The purpose of this study was to determine the relationship between average force, average torque, peak force, and peak torque produced by the knee musculature. Twenty women were assessed for isokinetic concentric and eccentric knee extensor and flexor muscular strength at a velocity of 90 deglsec.

Peak torque and OBLA running capacity in male orienteers

Acta Physiologica Scandinavica, 1988
The isokinetic (30, 60, 120 and 1800 s‐1) peak torque of m. quadriceps femoris and m. triceps surae, and the running velocity at the onset of blood lactate accumulation (V0BLa) were determined at three different occasions (November, April and September) during a year in 15 male elite orienteers.

Dynamic Peak Torque Related to Age, Sex, and Performance

Research Quarterly. American Alliance for Health, Physical Education, Recreation and Dance, 1979
Abstract The present study was designed to investigate the isokinetic peak torque at the highest speed of muscle shortening (210 degrees/second) related to age, sex, and physical performance. The subjects were 569 normal boys and girls, 13 to 17 years of age, and 35 swimmers, 11 to 21 years of age.
