Proteolytic capacity in mouse cardiac muscle following strenuous exercise

1981

Proteolytic capacity in mouse cardiac muscle was analyzed 1, 3, and 6 days after exhaustive intermittent or submaximal prolonged running. No significant changes were recorded in the activities of acid or alkaline proteases, β-glucuronidase or trypsin inhibitor. Similarly, no changes were found in the rates of acid or neutral autolysis.

Effects of the type of recovery training on the concentric strength of the knee extensors

1997

The aim of this study was to examine the effects of specific concentric and eccentric training on concentric muscular strength following an initial standardized period of excessive training that combined concentric and eccentric actions. For a period of 12 weeks, 37 young elite female basketball players performed standardized training, which included concentric and eccentric actions at 70% and 110% of one-repetition maximum (1-RM), respectively. They were then divided into three groups that followed 12 week programmes which included concentric (C-E/C, n = 13), eccentric (C-E/E, n = 13) or a combination of both concentric and eccentric (C-E/-E, n = 11) exercises. The standardized and specifi…

Impact or No Impact for Women With Mild Knee Osteoarthritis: A Bayesian Meta‐Analysis of Two Randomized Controlled Trials With Contrasting Interventi…

2022

Objective We aim to predict the probability of a benefit from two contrasting exercise programs for a woman with a new diagnosis of mild knee osteoarthritis (OA). The short and long-term effects of aquatic resistance training (ART) and high-impact aerobic land training (HLT) compared with the control will be estimated. Methods Original data sets from two previously conducted randomised controlled trials (RCT) were combined and used in a Bayesian meta-analysis. Group differences in multiple response variables were estimated. Variables included cardiorespiratory fitness, dynamic maximum leg muscle power, maximal isometric knee extension and flexion force, pain, other symptoms and quality of l…

Physical exercise neuroprotects ovariectomized 3xTg-AD mice through BDNF mechanisms.

2014

Postmenopausal women may be more vulnerable to cognitive loss and Alzheimer's disease (AD) than premenopausal women because of their deficiency in estrogens, in addition to their usually older age. Aerobic physical exercise has been proposed as a therapeutic approach for maintaining health and well-being in postmenopausal women, and for improving brain health and plasticity in populations at high risk for AD. To study the neuroprotective mechanisms of physical exercise in a postmenopausal animal model, we submitted previously ovariectomized, six-month old non-transgenic and 3xTg-AD mice to three months of voluntary exercise in a running wheel. At nine months of age, we observed lower grip s…

Lifestyle interventions targeting dietary habits and exercise in bipolar disorder: A systematic review.

2015

Abstract Background Bipolar disorder (BD) is a serious mental illness associated with a high risk of medical comorbidities, long-term disability and premature death. This systematic review examined the current literature on therapeutic interventions targeting nutrition, physical activity and wellness in BD and collecting health-related measures such as mood and course of illness. Methods Scopus (all databases), Pubmed and Ovid Medline were systematically searched with no language or year restrictions, up to June 2015, for studies focusing on lifestyle interventions in BD. Search terms were related to bipolar disorder, nutrition, physical activity, wellbeing, psychosocial interventions and c…

Is cell salvage safe in liver resection? A pilot study

2007

Abstract Study Objective To investigate the quality of cell salvaged (CS) blood in patients undergoing hemihepatectomy (study group) and compare it with CS-blood from aortic surgery (control group). Design Observational study. Setting Operating room in a university hospital. Measurements 6 patients undergoing hemihepatectomy or aortobifemoral bypass with intraoperative blood loss of more than 800 mL. Samples were drawn from the central venous catheter, from the reservoir of a CS recovery system, and from the processed blood in each patient to determine interleukin (IL)-6, IL-8, IL-10, tumor necrosis factor (TNF), complement C3a, and the terminal complement complex C5b-9. Microbiological ana…

The Effectiveness of Physical Exercise on Bone Density in Osteoporotic Patients

2018

Physical exercise is considered an effective means to stimulate bone osteogenesis in osteoporotic patients. The authors reviewed the current literature to define the most appropriate features of exercise for increasing bone density in osteoporotic patients. Two types emerged: (1) weight-bearing aerobic exercises, i.e., walking, stair climbing, jogging, and Tai Chi. Walking alone did not appear to improve bone mass; however it is able to limit its progressive loss. In fact, in order for the weight-bearing exercises to be effective, they must reach the mechanical intensity useful to determine an important ground reaction force. (2) Strength and resistance exercises: these are carried out with…

Cardiac troponin release during and after endurance exercise: epidemiologic health implications.

2020

Measuring physical activity with activity monitors in patients with heart failure: from literature to practice. A position paper from the Committee o…

2020

The aims of this paper were to provide an overview of available activity monitors used in research in patients with heart failure and to identify the key criteria in the selection of the most appropriate activity monitor for collecting, reporting, and analysing physical activity in heart failure research. This study was conducted in three parts. First, the literature was systematically reviewed to identify physical activity concepts and activity monitors used in heart failure research. Second, an additional scoping literature search for validation of these activity monitors was conducted. Third, the most appropriate criteria in the selection of activity monitors were identified. Nine activi…

Physical exercise program, a strategy to prevent cardiotoxicity in early breast cancer: A literature review

2018

Breast cancer, the most common in women, is a cancer of good prognosis. During this last decade, the improvement of cancer screening and treatment has significantly increased disease-free and overall survival. However, the chemotherapy, especially based on anthracyclines, and targeted therapies like trastuzumab have a toxicity to the cardiovascular system. If physical exercise is recognized as beneficial in tertiary prevention, especially by reducing fatigue, improving the physiological capacities of exercise, muscle strength and ultimately quality of life, conversely, few data are available on the effects of exercise on treatment-induced cardiotoxicity. This review, based on the PubMed dat…
