Abstract:

To evaluate the Q/H strength ratio, before and after the isotonic exercises. The Quasi experimental design was selected in this study. 50 female patients with knee osteoarthritis and disturbed Quadriceps – Hamstring (Q/H) ratio were assessed through Visual Analog Scale (VAS), Range Of Motion, Kellgren-Lawrence Scale and Repetition Maximum (RM). All of the patients were assessed at 1st visit, and then 15 sessions of isotonic exercises were given. They were examined again at 15th day to assess the effects of isotonic exercises on Q/H ratio. There was a significant difference in Q/H ratio before

Abstract:

Background and Study Aim. Scientific-methodical literature underlined the importance of improving the effectiveness of physical education’s tools and methods during the scheduled university lessons. Scientists point out the necessity to take into account every factor determining the training effect of lessons with strength exercises. The immediate training effect can be determined by measuring the heart rate during different modes of strength exercises and during recovery. The aim of this study is to analyse the strength exercises’ immediate training effect on a student’s body in the static mo

The aim of the current review is to discuss applications and mechanism of eccentric exercise in training regimes of competitive sports. Eccentric muscle work is important in most sports. Eccentric muscle contractions enhance the performance during the concentric phase of stretch-shortening cycles, which is important in disciplines like sprinting, jumping, throwing, and running. Muscles activated during lengthening movements can also function as shock absorbers, to decelerate during landing tasks or to precisely deal with high external loading in sports like alpine skiing.

Sixteen young participants were required to perform fatiguing sub-maximal isotonic exercises. Postural sway was recorded using a force plate before and after the exercises.

Context: Resistance training exercise prescription is often based on exercises performed at a percentage of a 1-repetition maximum (1RM). Following knee injury, there is no consensus when a patient can safely perform 1RM testing. Resistance training programs require the use of higher loads, and loads used in knee injury rehabilitation may be too low to elicit gains in strength and power.

Abstract:

In the past, the measurement of O2 consumption (O˙2) by the muscle could be carried out noninvasively by near-infrared spectroscopy from oxyhemoglobin and/or deoxyhemoglobin measurements only at rest or during steady isometric contractions. In the present study, a mathematical model is developed allowing calculation, together with steady-state levels ofO˙2, of the kinetics of O˙2readjustment in the muscle from the onset of ischemic but aerobic constant-load isotonic exercises. The model, which is based on the known sequence of exoergonic metabolic pathways involved in muscle energetics, allows

The subjects ( n = 5) performed squatting exercises with a countermovement at varied deceleration rates before lifting the load. The ground reaction force and video images were recor

Abstract:

Electrical Bioimpedance Spectroscopy (EIS) is a technique used to assess passive electrical properties of biological materials. EIS detects physiological and pathological conditions in animal tissues. Recently, the introduction of broadband excitation signals has reduced the measuring time for application techniques such as Electrical Bioimpedance Myography. Therefore, this work is aimed at proposing a prototype by using discrete interval binary sequences (DIBS), which is based on a system that holds a current source, impedance acquisition system, microcontroller and graphical user interface.

Abstract:

The current study proposes an intervention of oral-motor techniques, targeting peripheral stimulation with central-level effects, where synaptic densification is expected to allow a more coordinated motor response, with positive outcomes on the speech inteligibility. The intervention techniques belong to quite different fields: myofunctional techniques (posture determination, isotonic exercises for the oral musculature), oro-facial massage according to the C. Morales method, passive stimulation with a vibrating instrument (z-vibe) and repetitions of diadokokinetics. An ABA (single-subject expe

Abstract:

The objectives of this study were to evaluate the efficacy of two separate countermeasures, exercise and protein supplementation, to prevent muscle strength and lean tissue mass losses during 60 days of bed rest (BR) in women and whether countermeasure efficacy was influenced by pre-BR muscular fitness (strength, endurance, tissue mass). Twenty-four women were assigned to an exercise (EX, n = 8), a no-exercise control (CON, n = 8), or a no-exercise protein supplementation group (PROT, n = 8). EX performed supine treadmill exercise within lower body negative pressure 3–4 days/wk and maximal con

Abstract:

Elbow ligament injuries are commonly caused by overuse; degeneration; and trauma; such as from a fall or collision. The purpose of this study was to present the results of three cases involving patients undergoing early rehabilitation after surgical treatment for complex injury of the elbow medial collateral ligament (MCL) and lateral collateral ligament (LCL). Two patients were non-athlete middle-aged women and one was a recreational judo player. Surgery was performed through open incision or arthroscopically. Rehabilitation consisted of range of motion (ROM) exercise; muscle strength restora
