  • ANOVA
  • Changes in indirect muscle damage markers after 30MVEC were compared among the groups by mixed‐design two‐way ANOVA. (deepdyve.com)
  • submaximal
  • Three-dimensional force components were recorded during submaximal isometric wrist extensions on day 0, day 4, and before, during, and after saline-induced pain on day 2. (edu.au)
  • torque
  • The following parameters were evaluated before and after DF contraction:Plantar flexion MVIC, Maximal Rate of Torque Development (MRTD), time of MRTD and the RTD for the period 0-30, 0-50, 0-100 and 0-200 ms after the torque onset. (eqoljournal.com)
  • Specifically, we hypothesised that regular wearing of stilettos would lead to a shortening of the fascicles of the gastrocnemius muscle together with changes in the mechanical properties of the Achilles' tendon (AT), resulting in functional alterations, as seen in the torque-angle and torque-velocity relationships.

  • In humans, one common condition that places muscle-tendon units (MTUs) in a shortened position is high heel (HH) wearing. (biologists.org)
  • tetanus
  • Recent data obtained from Rana temporaria sartorius muscles during an isometric tetanus indicate that the time-course of phosphocreatine (PC) splitting cannot account for the total energy (heat + work) liberation (Gilbert et al. (rupress.org)
  • peak
  • The muscle activation during force was determined as the root mean square (RMS) electromyographic signal normalized to the peak RMS EMG signal of isometric contraction for 10 s. (iospress.com)
  • Ballet dancers spend considerable time during their routines with their heels elevated in the peak-contraction calf raise position. (t-nation.com)
  • intensities
  • Reliability of EMG-force relationship models was higher within than between days, but typically acceptable for all but the lowest contraction intensities, and enables adjustment for measurement imprecision in future studies. (springeropen.com)
  • The aim of this study was to ascertain whether such training influences oxygenation and endurance of forearm muscles at higher as well as lower testing intensities. (springer.com)
  • oxygenation
  • The results revealed that muscle strength-endurance training increased performance of forearm muscles during 150 N contraction with an accompanied increase in oxygenation of the exercising muscles. (springer.com)
  • In contrast, the same training did not influence the performance of forearm muscles during ice-axe-grasping in spite of increased oxygenation. (springer.com)
  • This may be due to oxygenation levels that were below the limit where oxygenation may influence the duration of the contraction. (springer.com)

  • calf
  • Wearing high heels (HH) places the calf muscle-tendon unit (MTU) in a shortened position. (biologists.org)
  • As muscles and tendons are highly malleable tissues, chronic use of HH might induce structural and functional changes in the calf MTU. (biologists.org)
  • Contrary to the experimental conditions used for animal muscles, however, the calf MTU is not immobilised in women wearing HH but is rather coerced to temporarily operate at reduced length. (biologists.org)
  • effect
  • These results demonstrated that the existence of the reversal effect of the antagonists is not appeared always in untrained groups and especially for the joint angle it is affected by the training background only for selective parameters of muscle contraction. (eqoljournal.com)
  • heart muscle cells has been associated with a cardioprotective effect of β 2 -AR agonists, via attenuation of G s -mediated inotropic response. (aspetjournals.org)
  • stiffness
  • At the plateau of the isometric contraction in control solution, the hs stiffness is 22.8 +/- 1.1 kPa nm(-1). (unifi.it)
  • We conclude that long-term use of high-heeled shoes induces shortening of the GM muscle fascicles and increases AT stiffness, reducing the ankle's active range of motion. (biologists.org)
  • neural
  • Plus, isometrics increase the neural drive between the motor cortex in your brain and the trained muscle. (t-nation.com)
  • This is the least effective time to use an isometric because your descending neural drive and largest motor units are already fatigued from the reps that preceded it. (t-nation.com)
  • activity
  • The EMG analyses indicated that muscle activity was significantly increased when additional motivational factors were introduced. (dtic.mil)
  • Associations between the masticatory system and muscle activity of other body districts. (semanticscholar.org)
  • In addition, the EMG signal activity on the muscle belly had less variability than the upper and lower parts (8.55% vs. 15.12% and 12.86%, respectively). (iospress.com)
  • strength
  • Clinical orthopedic measures such as manual muscle testing may provide an indication of muscle strength but no direct insight into the extent a muscle group is being activated. (symbiosisonlinepublishing.com)
  • The strength of shoulder abduction and electronic activities of six muscle groups in the upper body were tested on seven subjects in this study. (semanticscholar.org)
  • Sarcopenia is the age-related loss of muscle mass and strength and has been associated with an increased risk of falling and the development of metabolic diseases. (springermedizin.de)
  • periods
  • For all subjects possible, the investigators will continue to monitor their stimulated muscle forces during their recovery periods or disease progression. (clinicaltrials.gov)
  • participants
  • On day 0, the extensor carpi radialis brevis muscle of healthy participants was injected with nerve growth factor (NGF) to induce persistent movement-evoked pain (n = 13) or isotonic saline as a control (n = 13). (edu.au)
  • On day 2, short-lasting pain was induced by injection of hypertonic saline into extensor carpi radialis brevis muscles of all participants. (edu.au)
