That's based on better results for perceived pain and maximal voluntary muscle contraction.

Not exact matches

«The Duchenne smile involves both voluntary and involuntary contraction from two muscles: the zygomatic major (raising the corners of the mouth) and the orbicularis oculi (raising the cheeks and producing crow's feet around the eyes),» according to Adoree Durayappah in Psychology Today.

The cyclists in the Montmorency tart cherry group maintained muscle function (as measured by maximum voluntary isometric contraction) and experienced a reduction in certain inflammatory responses following the simulated cycling race, compared to those consuming the placebo drink.

This Japan Aerospace Exploration Agency study takes a look the health benefits of applying electric stimulation to a muscle opposing the voluntary contraction of an active muscle.

There is another study that showed that the people who visualized their muscles during leg presses while resting, boosted their abilities of doing maximal voluntary contractions.

The maximum voluntary isometric contraction (MVIC) has been measured and recorded by placing electromyography electrolytes on each of the muscles — quads, hamstrings, and glutes.

The cyclists in the Montmorency tart cherry group maintained muscle function (as measured by maximum voluntary isometric contraction) and experienced a reduction in certain inflammatory responses following the simulated cycling race, compared to those consuming the placebo drink.

Every voluntary contraction starts as a signal that the brain sends down the nerves and into the muscle.

The study of electricity in muscles probably began as early as the middle of the 1600s, with the discovery of the electric ray fish and experiments using frog legs (Clarys, 1994; Reaz et al. 2006), although it was not until 1792 that it was discovered that electricity could actually produce muscle contractions (Reaz et al. 2006), and 1849, when it was found that electric potential difference (also known as voltage) could be monitored in voluntary muscle actions (Reaz et al. 2006).

The presence of different levels of muscle activity has been observed both using surface electrodes and fine wire (intramuscular electrodes) and during maximal voluntary isometric contraction (MVIC), resistance training exercises, and normal humans movements such as gait.

After ROM measurements, the subjects were familiarized with the myofascial foam rolling technique, performed the maximum voluntary contraction (MVC) with the interpolated twitch technique (ITT), and received a 100 - Hz tetanic muscle stimulation.

An interpolated twitch ratio was calculated comparing the amplitude of the interpolated twitch with the potentiated twitch to estimate the extent of inactivation during a voluntary contraction (interpolated doublet force / potentiated doublet force × 100 = percent of muscle inactivation)(10).

This study tested muscle activation during maximum voluntary contractions of hip extension, in different hip flexion joint angles while the knee was flexed, and found that gluteus maximus EMG amplitude was reduced by a third when the hip was flexed, compared to when it was fully extended.

They report that the pronated grip pull up produced comparable (120 % vs. 117 % of maximum voluntary isometric contraction (MVIC) levels) latissimus dorsi muscle activity compared with the supinated chin - up exercise.

They reported that the inverted row performed with a supinated grip produced superior (94 % vs. 79 % of maximum voluntary isometric contraction (MVIC) levels) latissimus dorsi muscle activity compared to the pronated grip inverted row variation.

Botton et al (2013) compared the bench press and the smith machine shoulder press, which reportedly ranged between 56 to 70 % maximum voluntary contraction (MVC) for the anterior deltoid muscle activity.
