Progression of core stability exercises based on the extent of muscle activity
2017
OBJECTIVE: The aim of this cross-sectional study was to evaluate a variety of isometric plank exercises.DESIGN: Twenty university students performed the following eight different variants of plank exercises in random order and with 1-min rest intervals: stable prone plank, suspended prone plank, stable roll-out plank, suspended roll-out plank, unilateral stable prone plank, unilateral suspended prone plank, stable lateral plank, and suspended lateral plank. Surface electromyography signals were recorded for the upper rectus abdominis, lower rectus abdominis, external oblique, lumbar erector spinae, and normalized to the maximum voluntary isometric contraction.RESULTS: The suspended prone pl…
Sarcopenia, Diet, Physical Activity and Obesity in European Middle-Aged and Older Adults: The LifeAge Study
2021
The revised European consensus defined sarcopenia as a progressive and generalized skeletal muscle disorder that is associated with an increased likelihood of adverse outcomes including falls, fractures, physical disability and mortality. The aim of this study was to determine the prevalence of sarcopenia and analyse the influence of diet, physical activity (PA) and obesity index as risk factors of each criteria of sarcopenia. A total of 629 European middle-aged and older adults were enrolled in this cross-sectional study. Anthropometrics were assessed. Self-reported PA and adherence to the Mediterranean diet were evaluated with the Global Physical Activity Questionnaire (GPAQ) and Preventi…
Gender-related differences in serum uric acid in treated hypertensive patients from central and east European countries: findings from the Blood Pres…
2019
OBJECTIVE: Hyperuricemia has been associated with high blood pressure (BP) values, diabetes mellitus, metabolic syndrome and chronic kidney disease (CKD). In the present study, we assessed the gender-related relationships between serum uric acid (SUA) and cardionephrometabolic variables in central and east European hypertensive patients. METHODS: A total of 3206 treated hypertensive patients with available SUA levels from the BP-CARE study was analyzed. Correlations among SUA, BP values, BP control, diabetes mellitus, metabolic syndrome and CKD were performed according to gender. RESULTS: Twenty-five percent of the whole population showed hyperuricemia (28% in women and 23% in men). These p…
Associations of physical activity, sedentary time, and cardiorespiratory fitness with heart rate variability in 6- to 9-year-old children: the PANIC …
2019
Abstract Purpose To study the associations of physical activity (PA), sedentary time (ST), and cardiorespiratory fitness (CRF) with heart rate variability (HRV) in children. Methods The participants were a population sample of 377 children aged 6–9 years (49% boys). ST, light PA (LPA), moderate PA (MPA), vigorous PA (VPA), and moderate-to-vigorous PA (MVPA), and PA energy expenditure (PAEE) were assessed using a combined heart rate and movement sensor, maximal power output per kilograms of lean body mass as a measure of CRF by maximal cycle ergometer exercise test, and HRV variables (SDNN, RMSSD, LF, and HF) using 5 min resting electrocardiography. Data were analysed by linear regression ad…
Serum ionized magnesium levels in relation to metabolic syndrome in type 2 diabetic patients
2006
Objective: To evaluate circulating serum ionized magnesium (i-Mg) concentrations in patients with type 2 diabetes mellitus, and to investigate its relationship with the components of the metabolic syndrome. Design: cross-sectional study. Setting: Outpatients' service for diabetic patients at the University Hospital of Messina, Italy. Subjects: 290 patients with type 2 diabetes mellitus. Measures of Outcome: Serum i-Mg was measured by ion selective electrode. Age, gender, body mass index (BMI), waist circumference, blood pressure, fasting glucose, HbA1c, HDL cholesterol, triglycerides, and urinary albumin excretion rate (UAER) were considered in the analyses. Patients with hypomagnesemia, de…
Balance Confidence Was Associated With Mobility and Balance Performance in Older People With Fall-Related Hip Fracture: A Cross-Sectional Study
2012
Abstract Portegijs E, Edgren J, Salpakoski A, Kallinen M, Rantanen T, Alen M, Kiviranta I, Sihvonen S, Sipila S. Balance confidence was associated with mobility and balance performance in older people with fall-related hip fracture: a cross-sectional study. Objective To study the relationship between balance confidence, a concept closely related to fear of falling, mobility and balance performance, and perceived mobility limitation in older people after a fall-related hip fracture. Design Cross-sectional analyses of pretrial data of 2 randomized controlled trials of physical rehabilitation. Setting University research center. Participants Community-dwelling people aged over 60 years, 6 week…
Polyphenol intake and cardiovascular risk in the PREDIMED-Plus trial. A comparison of different risk equations
2022
Abstract Introduction and objectives Quantification of cardiovascular risk has been based on scores such as Framingham, Framingham-REGICOR, SCORE or Life's Simple 7 (LS7). In vitro, animal, and randomized clinical studies have shown that polyphenols may provide benefits to the vascular system and reduce the inflammatory response. However, some clinical-epidemiological studies have yielded inconsistent results. Our aim was to assess the possible association between intake of the various polyphenol classes and established cardiovascular scores. Methods This cross-sectional analysis involved 6633 PREDIMED-Plus study participants. Food polyphenol content was estimated by a semiquantitative food…
Left Ventricular Hypertrophy in the Spanish Hypertensive Population. The ERIC-HTA Study
2006
Introduction and objectives. Left ventricular hypertrophy (LVH) is the earliest manifestation of cardiac damage in hypertension. Its appearance is associated with a poor cardiovascular prognosis. The objectives of this study were to determine the prevalence of electrocardiographic LVH and to assess the epidemiological characteristics of hypertensive patients receiving primary care. Patients and method. A cross-sectional multicenter study of hypertensive patients aged 55 years or more was carried out in a primary care setting. Blood pressure was measured using the standard method. Cardiovascular history was determined from medical records and LVH was assessed electrocardiographically using C…
Plasma Metabolomic Profiles of Glycemic Index, Glycemic Load, and Carbohydrate Quality Index in the PREDIMED Study
2020
Background The quality of carbohydrate consumed, assessed by the glycemic index (GI), glycemic load (GL), or carbohydrate quality index (CQI), affects the postprandial glycemic and insulinemic responses, which have been implicated in the etiology of several chronic diseases. However, it is unclear whether plasma metabolites involved in different biological pathways could provide functional insights into the role of carbohydrate quality indices in health. Objectives We aimed to identify plasma metabolomic profiles associated with dietary GI, GL, and CQI. Methods The present study is a cross-sectional analysis of 1833 participants with overweight/obesity (mean age = 67 y) from 2 case-cohort s…
Clinical Outcome and Subjective Quality of Life after Photodynamic Therapy in Patients with Age-Related Macular Degeneration
2005
PURPOSE. Whereas the efficacy of photodynamic therapy (PDT) in preventing the progression of age-related macular degeneration (ARMD) is established, its effect on quality of life is under discussion. METHODS. All patientswho underwent PDT during 2000 and 2001 at the University Eye Hospital of Mainz were interviewed using a standardized 82-item questionnaire on quality of life and patient satisfaction in ophthalmologic patients. Information was assessed in terms of 82 questions; global scores ranging from 1.0 (optimum self-estimated quality of life) to 4.0 (worst) were derived. Cataract patients' scores were used to characterize the ARMD patients' subjective outcome; the latter were then rel…
