Muscle strength before and mortality after a bone fracture in older people

2002

We studied whether muscle strength measured before a bone fracture predicts mortality following the fracture. The participants were a sub-cohort of 82 people of a total of 493 Evergreen project participants initially aged 75- and 80 years, who had participated in knee extension strength tests as part of the baseline examinations, and who subsequently suffered at least one bone fracture. Maximal isometric knee extension strength was measured at baseline using an adjustable dynamometer chair. Fracture surveillance was carried out from patient records for 5 years, and mortality surveillance from population register for 10 years after baseline examinations. Average time till a fracture occurred…

Physical activity compensates for increased mortality risk among older people with poor muscle strength

2006

The aim of the study was to determine whether habitual physical activity can compensate for the increased mortality risk among older people with poor muscle strength. Mortality was followed up for 10 years after laboratory examination in 558 community dwelling 75- and 80-year-old men and women. Maximal isometric strength of five muscle groups was measured and tertile cut-off points were used to categorize participants. Participants, who reported moderate physical activity for at least 4 h a week, were categorized as physically active and the others as sedentary. High muscle strength and physical activity both protected from mortality, but their effect was not additive. Within each muscle st…

Hemofilia: ejercicio y deporte

2011

El ejercicio físico y el deporte constituyen uno de los pilares básicos en el tratamiento de la hemofilia. Este trabajo describe un resumen de las características de la hemofilia y, a través de una exhaustiva revisión bibliográfica, se analiza la importancia de la condición física, en relación con la prevención y el tratamiento de las lesiones musculoesqueléticas en el paciente hemofílico. La hemofilia es una enfermedad hematológica hereditaria, con lesiones ortopédicas características. Afecta a individuos varones y presenta un déficit de factores de la coagulación que provoca hemorragias incluso espontáneas (en pacientes graves sin tratamiento). Las lesiones más frecuentes son: hemartrosis…

Physical exercise and sarcopenia in older people: position paper of the Italian Society of Orthopaedics and Medicine (OrtoMed)

2015

Sarcopenia is the age-associated loss of skeletal muscle mass and function. It is a major clinical problem for older people and research in understanding of pathogenesis, clinical consequences, management, and socioeconomic burden of this condition is growing exponentially. The causes of sarcopenia are multifactorial, including inflammation, insulin resistance, changing endocrine function, chronic diseases, nutritional deficiencies and low levels of physical activity. Operational definition of sarcopenia combines assessment of muscle mass, muscle strength and physical performance. The diagnosis of sarcopenia should be based on having a low appendicular fat free mass in combination with low …

2021

Background Physical activity alleviates chronic stress. The latest research suggests a relationship between resilience and physical fitness. Beneficial adaptations of the hypothalamic-pituitary-adrenal axis, sympathetic nervous system, endocannabinoid system, and tryptophan pathway, which are induced by an active lifestyle, are considered to be conducive to resilience. However, detailed knowledge on the molecular link between the effects of acute and chronic physical exercise and improved resilience to stress in humans is missing. Moreover, the relationship between innate and acquired aerobic capacity and resilience is poorly understood. Objective The aim of this study is to implement a hu…

Muscle performance, sex hormones and training in peri-menopausal and post-menopausal women

2003

Age-related deterioration in muscle performance is one of the major reasons for decreased functional capacity and disability in older people. In women, impaired muscle performance has already been observed during peri-menopause in concert with rapid and dramatic decrease in ovarian hormone production. This observation suggests that female sex steroids may have an important role among other agents in regulating muscle performance in middle-aged and older women. Previous experimental studies have shown that hormone replacement therapy (HRT) and intensive physical training have positive effects on muscle force and explosive power in healthy post-menopausal women. Hormone replacement therapy in…

SP0088 New drugs, but still comorbidity

2017

As the population ages the simultaneous presence of multiple pathological conditions in the form of comorbidity and multimorbidity is more a rule than an exception. Comorbidity is reported in 35 to 80% of all ill people (Taylor et al. 2010). Comorbidity and multimorbidity are challenging researchers, clinicians and policy makers as these persons require more frequent appointments and hospitalizations and are at a greater risk for drug interactions, disability and mortality (Slater 2011). Although numerous chronic disease prevention strategies and treatment guidelines have been developed, they mainly address single conditions and ignore the presence of co-existing conditions (van der Noyen 2…

An Extended Study on Training and Physical Exercise in Esports

2019

This chapter is an extended revision of the authors' earlier study (2016) on the training routines of professional and high-level esport players, with added focus on their physical exercise. The study is methodologically mixed with a quantitative survey sample (n=115) and a qualitative interview sample (n=7). Based on this data, high-level esport players train approximately 5.28 hours every day around the year, and professional esport players at least the same amount. Approximately 1.08 hours of that training is physical exercise. More than half (55.6%) of the professional and high-level esport players believe that integrating physical exercise into their training programs has a positive ef…

Anemia, heart failure and exercise training

2013

We read with interest the recent article by Wang et al. in which theauthors evaluated in anemic patients with heart failure whether exer-tionalperiodicbreathing influences rheological/hemodynamicfunctions[1]. For this purpose, the authors performed an incremental exercisetestusing a bicycle ergometer. In this regard, it has been generally assumedby some researchers, exercise physiologists and scientists that the incre-ment in blood hemoglobin (Hb) content is among the main hematolog-ical adaptations to endurance exercise training. This misconception isbased in the data published in diffe rent studies carried out severalyearsago [2].Inarecentmanuscript byBakeretal. [3],theauthorsdem-onstrated…
