2016/5/16
Background:It is habitual for combat sports athletes to lose weight rapidly to get into a lower weight class. Fluid restriction, dehydration by sweating (sauna or exercise) and the use of diuretics ar...
Concentric and Eccentric: Muscle Contraction or Exercise?
Concentric and Eccentric Muscle Contraction Exercise
2015/5/18
This inclusion considers the use and possible misuse of the terms ''Concentric and Eccentric'' in three possible contexts: first, the origin of terms; second, different approaches; and third, the poss...
Influence of Type of Muscle Contraction and Gender on Postactivation Potentiation of Upper and Lower Limb Explosive Performance in Elite Fencers
Warm-up vertical jump bench-press fatigue isometric plyometric
2015/5/7
The purpose of this study was to evaluate the postactivation potentiation (PAP) effect of isometric and plyometric contractions on explosive performance of the upper and the lower limbs in male and fe...
POSTURAL SWAY RESPONSE TO MAXIMAL EXERCISES WITH DIFFERENT FORMS OF MUSCLE CONTRACTION
form of muscle contraction level running postural stability upslope running
2009/8/26
The study compares parameters of balance after treadmill upslope and level running involving different form muscle contraction. A group of 14 PE students (age 19.2 ± 2.9 years, height 180.0 ± 7.3 cm, ...
Effects of stretching stress on the muscle contraction proteins of skeletal muscle myoblasts
stretching stress muscle contraction proteins skeletal muscle myoblasts
2009/3/2
Several studies have reported that growth and differentiation of cultured myoblasts can be facilitated by applying appropriate mechanical stimulus. However, the effects of mechanical stimulus on the c...
Cavernosus Muscle Contraction During Erection：Is It Voluntary or Reflex, Given the Striated Nature of the Muscles?
Ischio-/bulbo-cavernosus muscle corpora cavernosa intracorporal pressure electromyography
2008/12/24
The bulbo- and ischio-cavernosus muscles (BCM, ICM) contract in the rigid erection phase, leading to a suprasystolic cavernosal pressure. We investigated the hypothesis that the contraction of caver...
In vivo myograph measurement of muscle contraction at optimal length
In vivo myograph measurement muscle contraction
2010/2/26
We present a newly developed myograph, an accurate measuring device for muscle contraction, consisting of three elements. Firstly, an element for adjusting the axle of the device and the physiological...
Mechanism of muscle contraction based on stochastic properties of single actomyosin motors observed in vitro
molecular motor Brownian motion single molecule preferential landing loose coupling
2010/12/2
We have previously measured the process of displacement generation by a single head of muscle myosin (S1) using scanning probe nanometry. Given that the myosin head was rigidly attached to a fairly la...
