The aim of the study was to establish relations between the acute and chronic fatigue of workers, and between chronic fatigue and age dynamics of indices of health. In 859 women, white-collar workers, with normal fatigue at work of various degree and different physiological labor intensity there was determined an annual gain of professional risks (GPR): syndromes of motor, visual, and non-specific chronic fatigue; indices of the physical performance; morbidity with temporary disability. During the year the health is deteriorating both in 59% of women who are very tired at work, and 63% of wome

Fatigue is a frequent symptom reported by persons living with HIV disease and one that affects all aspects of quality of life. To improve quality of care of persons with HIV disease, it is important to address all factors that contribute to fatigue.

Much of the spotlight for coronavirus disease 2019 (COVID-19) is on the acute symptoms and recovery. However, many recovered patients face persistent physical, cognitive, and psychological symptoms well past the acute phase. Of these symptoms, fatigue is one of the most persistent and debilitating. In this “perspective article,” we define fatigue as the decrease in physical and/or mental performance that results from changes in central, psychological, and/or peripheral factors due to the COVID-19 disease and propose a model to explain potential factors contributing to post-COVID-19 fatigue.

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a chronic illness that is defined and diagnosed by its symptoms: extreme fatigue made worse by physical and mental activity, pain and decreased mental stamina, among others. A long-held, erroneous belief that ME/CFS is not a physiological illness has persisted among some clinicians, leading to the denial of a patient’s physical illness and attributing the symptoms to other causes. The debilitating effects of ME/CFS in the pediatric population can affect all aspects of academic, social, emotional, and physical development. ME/CFS ha

It has a profound long-term impact on the life of the affected person. ME/CFS is diagnosed primarily by the exclusion of other fatigue illnesses, but the availability of multiple case definitions for ME/CFS has complicated diagnosis for clinicians.

Wildland firefighters perform physical work while being subjected to multiple stressors and adverse, volatile working environments for extended periods. Recent research has highlighted sleep as a significant and potentially modifiable factor impacting operational performance. The aim of this review was to (1) examine the existing literature on firefighters’ sleep quantity and quality during wildland firefighting operations; (2) synthesise the operational and environmental factors that impact on sleep during wildland firefighting; and (3) assess how sleep impacts aspects of firefighters’ health

Glycolytic flux in white muscle can be increased several-hundredfold by exercise. Phosphofructokinase (PFK; EC 2.7.1.11) is a key regulatory enzyme of glycolysis, but how its activity in muscle is controlled is not fully understood. In order not to neglect integrative aspects of metabolic regulation, we have studied in frogs (Rana temporaria) a physiological form of muscle work (swimming) that can be triggered like a reflex. We analysed swimming to fatigue in well rested frogs, recovery from exercise, and repeated exercise after 2 h of recovery. At various times, gastrocnemius muscles were tes

As a systematic process of data collection and evaluation, the monitoring of recovery can be implemented for various purposes. It may help prevent negative outcomes of training or competition, such as underrecovery, overtraining, or injuries. Furthermore, it aims to establish routines and strategies necessary to guarantee athletes’ readiness for performance by restoring their depleted resources.

Many of these signs and symptoms represent the same alterations that are usually attributed to the process of ageing.

The main criteria for the functioning of agronomic phytocoenosis are indicators of their economic and energy efficiency. In particular, the issues of manufacturability and rational use of sown areas during the growing season characterize the level of agronomic culture in a particular geographical area. Under these conditions, it is important to study the possibility of joint cultivation of agricultural plants, which will reduce energy consumption, improve the phytosanitary condition of crops and increase the profitability of agricultural production.

Abstract Introduction. When evaluating the swimming technique of people with disabilities, a particularly important factor, besides physiological aspects, is the efficiency of the effort expended. This suggests that assessing and monitoring the effectiveness of swimming should be a regular part of training for swimmers with disabilities. Therefore, it seems important to distinguish how changes occur in the parameters that determine the effectiveness of swimming. This is especially true of anaerobic lactic exercise as the lactic acid concentration in the blood increases significantly. The aim o

Over the last 2 to 3 years these systems have evolved rapidly with the development and use of algorithms which permit the autonomous regulation of basal insulin. Correct control and administration of basal insulin is often the greatest stumbling block in multiple daily injection therapy as basal insulins cannot replicate t
