Objective: to compare the different adipose tissue (AT) compartments, muscle mass, muscle fat infiltration, coronary calcium, as well as associations among changes in different AT compartments between frail and robust nonagenarians. Materials and methods: Forty-two elderly subjects took part in this study: 29 institutionalized frail elderly (92....
Article
OBJECTIVE In adults, there is evidence that improvement of metabolic-associated fatty liver disease (MAFLD) depends on the reduction of myosteatosis. In children, in whom the prevalence of MAFLD is alarming, this muscle-liver crosstalk has not been tested. Therefore, we aimed to explore whether the effects of a multicomponent intervention on hepati...

Background Falls represent important drivers of intrinsic capacity losses, functional limitations and reduced quality of life in the growing older adult’s population, especially among those presenting with frailty. Despite exercise- and cognitive training-based interventions have shown effectiveness for reducing fall rates, evidence around their pu...
Article

Chapter
Aging is an unavoidable process but the benefits of regular exercise have been proven to have a major impact on maintaining quality of life. A combination of factors at cellular and molecular level, the presence of conditions such as obesity or malalignment problems, together with a history of past injuries (cartilaginous, ligamentous, meniscal as...
Article
Frailty is an important concept in clinical and demographic research in the elderly because of its incidence level and its relationship with adverse outcomes. Functional ability declines with advanced age, likely due to changes in muscle function. This study aimed to examine the relationship between muscle quality and muscle power with kinematics f...

Article
It is generally accepted that preadolescents have a limited capacity to develop muscle hypertrophy in response to exercise compared with older populations; however, studies are scarce and conflicting. The main aim of the present study was to assess if playing tennis is associated with the hypertrophy of dominant pectoralis muscles (PM) in professio...
Article
Background: Frailty has become the center of attention of basic, clinical and demographic research because of its incidence level and the gravity of adverse outcomes with age. Moreover, with advanced age, motor variability increases, particularly in gait. Muscle quality and muscle power seem to be closely associated with performance on functional t...
Article
Most hospitalized older adults have reduced functional and physiological reserves, rendering them more vulnerable to the effects of a series of circumstances beyond the existence of health conditions unrelated to the reason for the hospitalization, usually worsening the hospitalization outcome. Despite the theoretical support for the idea that mobi...

This study examined the effects of heavy resistance training on physiological acute exercise-induced fatigue (5 x 10 RM leg press) changes after two loading protocols with the same relative intensity (%) (5 x 10 RM(Rel)) and the same absolute load (kg) (5 x 10 RM(Abs)) as in pretraining in men (n = 12). Exercise-induced neuromuscular (maximal stren...

Increased circulating adiponectin and insulin sensitivity are usually observed after body fat loss induced by a weight-loss diet. Progressive resistance training (PRT) without a concomitant weight-loss diet significantly decreases visceral fat, thus improving insulin sensitivity. Therefore, the purpose of this study was to ascertain the effects of...

Although ultrasound guidance is extensively used in percutaneous interventional procedures, the limitations of B-mode, gray-scale sonographic guidance can restrict clinical use. Little attention has been paid to the use of color Doppler sonography during such procedures. There are several ways in which color Doppler sonography can facilitate percut...
