Predictors of decline in self-assessments of health among older people--a 5-year longitudinal study.
2001
Within the framework of the Evergreen project we examined how changes in several indicators of health and functioning and physical activity predicted a decline in self-assessments of health evaluated over a 5-year period in older people by two different measurements: self-rated health (SRH) and self-assessed change in health (SACH). The study group comprised all 75-year-old persons born in 1914 (N = 382) and living in Jyvaskyla, a town in central Finland. At baseline in 1989, 91.6%, and at follow-up 5 years later in 1994, 87.3% of those eligible participated in the interview and 77.2 and 71.3%, respectively, in the examinations in the study centre, focusing on different domains of health an…
Associations Between the Residential Environment and Physical Activity in German College Students and the Role of Self-Efficacy as a Mediator
2014
Social-ecological models suggest that influences on physical activity should be examined on multiple levels, but most of the empirical studies in this area have investigated the different levels separately. To integrate the different levels, we examined self-efficacy with respect to physical exercise as a mediator of the relation between environmental characteristics and physical activity. In a cross-sectional German study, 1,292 college students completed a questionnaire that included measures of their perceived residential environment, self-efficacy, and physical activity. Structural equation modeling was used to assess direct and indirect effects on physical activity. The cycling and wa…
Rilevazione statistica della diffusione e della conoscenza di sostanze dopanti, integratori e dell' Exercise Addiction
2014
I benefici derivanti dalla pratica dell'esercizio fisico sono stati ampiamente documentati. Tuttavia, l’eccessivo ricorso alla attività fisica può condurre alla messa in atto di pattern compulsivi di allenamento che possono evolversi in una vera e propria patologia: l' exercise addiction. Studi recenti suggeriscono l'espansione di due fenomeni: il doping amatoriale e l'abuso di integratori per lo sport. Sono stati somministrati 686 test. I partecipanti allo studio sono stati scelti tra studenti di scuola media superiore, studenti universitari e frequentatori di ambienti sportivi. Il 42,5% degli intervistati dichiara di assumere sostanze per migliorare le prestazioni sportive e quindi di dop…
Modifications of atrial natriuretic peptide and vasopressin peptides in the rat hypothalamic supraoptic nucleus during resistance training
2010
Many studies have demonstrated the involvement of atrial natriuretic peptide (ANP) and vasopressin (VP) in the homeostasis of body fluids, but few studies have regarded the hypothalamic magnocellular neurosecretory system during physical exercises. The aim of the present immunohistochemical work is to study the activity of ANP and VP secreting neurons of the hypothalamic supraoptic nucleus during and after resistance training. The study was carried out in Wistar rats trained by a physical resistance-type exercise, using a rung ladder and a varying load fastened to the tail of each rat; the exercise lasted 20 min everyday for periods of 15, 30 and 45 days. Animal groups were sacrificed at th…
Extracellular Vesicles: Delivery Vehicles of Myokines
2019
Movement and regular physical activity are two important factors that help the human body prevent, reduce and treat different chronic diseases such as obesity, type 2 diabetes, heart diseases, hypertension, sarcopenia, cachexia and cancer. During exercise, several tissues release molecules into the blood stream, and are able to mediate beneficial effects throughout the whole body. In particular, contracting skeletal muscle cells have the capacity to communicate with other organs through the release of humoral factors that play an important role in the mechanisms of adaptation to physical exercise. These muscle-derived factors, today recognized as myokines, act as endocrine and paracrine hor…
Pediatric exercise programs in children with hematological cancer: a systematic review
2013
In the world today, there are roughly 25 million cancer survivors. Progress in treatments have greatly improved cure rates, with 5-year survival now approaching 80%, but are associated with numerous negative physical and psychological side-effects and a deterioration in the quality of future life. Cancer survivors are at increased risk for second cancers, other forms of comorbidity (e.g., cardiovascular disease, diabetes, osteoporosis), and functional decline. Lifestyle factors, such as a healthy diet, regular exercise, and smoking cessation may prevent these conditions and improve survivors’ quality of life. Observational research has shown that the physical activity levels of survivors of…
RUOLO DELL’ESERCIZIO FISICO NELLA QUALITÀ DI VITA DI SOGGETTI CON SCLEROSI MULTIPLA. ROLE OF EXERCISE IN THE QUALITY OF LIFE IN SUBJECTS WITH MULTIPL…
2012
La sclerosi multipla è una patologia neurodegenerativa cronica che ha un impatto considerevole sullo stato fisico, psicologico e sociale dei pazienti, influenzando negativamente la loro qualità di vita. Tra i fattori contribuenti ad una ridotta qualità di vita sono inclusi la presenza di dolore, spasmi, sindromi depressive, l’aumento della fatica e la riduzione della forza muscolare, mobilità ed autonomia nella deambulazione. Accanto alla medicina convenzionale, varie forme di medicina complementare ed alternativa, tra cui l’esercizio fisico, sono utilizzate dai soggetti con sclerosi multipla. Tuttavia, poche sono le prove scientifiche a sostegno della loro efficacia nel ridurre i sintomi d…
The use of protein supplementation among fitness center attendees. The protein project
2014
Nowadays, in a gym context we may find three people among ten who declare protein supplements consumption. Health, physical fitness, self esteem, performance and muscle hypertrophy are usually the main reasons inducing such kind of consumption. It well documented that particularly active individuals use supplements to build muscle, gain strength or prevent future diseases and illnesses. Furthermore, scientific researchers have shown that in general people have different opinions about the use of supplements and the appropriate food to eat. As reported by Bianco and colleagues in 2011, proteins are the most widely ingested supplements in people attending commercial gyms and supplement users …
Effects of conjugated linoleic acid and endurance training on peripheral blood and bone marrow of trained mice
2007
Fat supplements, es- pecially conjugated linoleic acid (CLA), are increasingly popular ergogenic aids among endurance athletes. To evaluate the im- portance of fat supplementation in the practice of endurance sports, we investigated the effects of CLA supplementation on body weight, muscle hypertrophy, peripheral blood composition, and bone marrow composition in healthy, young, endurance- trained mice. Young, healthy mice were subdivided into control, trained, and treated groups, according to their running atti- tudes. Training was performed over a period of 6 weeks on a treadmill, at a gradually increasing duration and speed. CLA- treated groups were gavaged with 0.425 mg·d 1 CLA supplemen…
Lactate level and handgrip test in migraine and fibromyalgia after self-myofascial release treatment
2019
The Aim of the study was to determine the effect of self-myofascial release (SMFR) treatment on handgrip test score in patients with fibromyalgia and migraine, investigating also if the lactate levels influenced the result. Twenty-five subjects affected by migraine (age 49.7±12.5; height 164.9±6.62 cm; weight 68.6±16.9 kg) and ten subjects affected by fibromyalgia (age 43.7±21.2; height 158±5.65 cm; weight 70±28.9 kg) were enrolled in the study. The assessments included a handgrip test, in order to evaluate isometric strength of both hands and forearm muscles and the lactate levels evaluation. The treatment was performed in the three most painful trigger points indicated from subjects as to…
