The aim of this study was investigate the effects of different intrasession exercise orders in the neuromuscular adaptations induced by concurrent training in elderly. Twenty-six healthy elderly men (64.7 ± 4.1 years), were placed into two concurrent training groups: strength prior to (SE, n = 13) or after (ES, n = 13) endurance training. Subjects trained(More)
The purpose of the present study was to investigate the relationship between echo intensity, neuromuscular and cardiorespiratory performances in the elderly. Thirty-one healthy elderly men (65.5±5.0) participated in this study. Echo intensity of rectus femoris and quadriceps femoris muscle thicknesses was determined by ultrasound images. Lower-body(More)
Eleven subjects performed isometric knee extensor contractions at maximum voluntary contraction (MVC), and at 70% of MVC preceding and following a fatigue test. The fatigue test consisted of a continuous isometric knee extensor contraction at 70% of MVC. The purpose of this study was to describe and compare the behavior of electromyographic (EMG) and(More)
The goal of this study was to evaluate if isolated sarcomeres and half-sarcomeres produce a long-lasting increase in force after a stretch is imposed during activation. Single and half-sarcomeres were isolated from myofibrils using micro-needles, which were also used for force measurements. After full force development, both preparations were stretched by(More)
According to the force-length relationship, cat soleus optimal sarcomere length should lie between 2.3-2.5μm. Rack and Westbury (1969) found optimal sarcomere length around 2.8- 3.0μm. The purpose of this study was to repeat their study to check for these discrepancies between the expected and the measured optimal length. The soleus muscle of both hindlimbs(More)
Strength training seems to be an interesting approach to counteract decreases that affect knee extensor strength, muscle mass and muscle quality (force per unit of muscle mass) associated with ageing. However, there is no consensus regarding the changes in muscle mass and their contribution to strength during periods of training and detraining in the(More)
Information Technology (IT) is strategic for organization management (Stair & Reynolds, 2005), although, many companies lack IT governance and planning, skilled people, defined and institutionalized methods and procedures, internal controls and indicators, and structures for agreement service levels and information security, legality, and economy. In this(More)
The effects of length changes in the in-situ cat soleus muscle on vibromyographic (VMG) signals were assessed using electrical stimulation of the soleus nerve in three adult male cats. Force and VMG signals were measured using an E-shaped force transducer and a miniature, unidirectional accelerometer, respectively. In each test, the soleus nerve was(More)
