Health Behavior in Hypochondriasis
2015
The relationship between health behavior and hypochondriasis has not yet been sufficiently examined, as previous studies investigated only individual dimensions of health behavior. In the present study, we extend current literature by examining multiple dimensions of health behavior. One hundred twenty-six participants, consisting of 40 participants with a primary diagnosis of hypochondriasis, 41 participants with a primary diagnosis of anxiety disorder, and 45 healthy controls, completed a multidimensional questionnaire for the assessment of health behavior and other measures for the evaluation of general psychopathology, illness anxiety, depression, and general anxiety. Patients with hypo…
Preferences of Physical Education Profiles Among Polish Adolescents
2020
The purpose of this study was to examine the association of preferred profiles of Physical Education (PE) classes with gender and school level among Polish adolescents. In the cross-sectional survey study, participated 1,340 Polish students (including 50% of girls), attending middle and high schools, aged between 13–19 years old. The participants selected one of four preferred profiles of PE classes. The majority (n = 845, 63%) of students participated in PE for "fun – pleasure – entertainment", whereas only one third of students (n = 419, 31%) preferred "exercise – sweat – fitness" as a profile of PE classes. The preference of "fun – pleasure – entertainment" decreased about 41% for boys a…
Dose-dependent absorption and elimination of cefadroxil in man.
1991
The pharmacokinetic behaviour of cefadroxil was dose-dependent in healthy male volunteers following the oral administration of single doses of 5, 15, and 30 mg.kg-1. As the dose of cefadroxil increased from 5 to 15 and 30 mg.kg-1, the peak plasma concentrations, normalized to 5 mg.kg-1, decreased significantly from 15.1 to 10.7 and 7.6 mg.l-1, while the corresponding normalized areas under the plasma concentration-time curves from 0 to 2 h decreased significantly from 1258 to 946 and 801 min.mg.l-1. When the same subjects were given 5 mg.kg-1 of cefadroxil together with 45 mg.kg-1 of cephalexin, the absorption of cefadroxil was slowed to a similar or greater extent than with the high dose o…
Cortico-bulbar fibers to orofacial muscles: recordings with enoral surface electrodes.
1997
A new recording technique was developed to eliminate current problems on recording transcranial evoked facial muscle responses. A fork-shaped device equipped with 2 pairs of Ag/AgCl-electrodes was inserted enorally at the buccinator muscle level. Advantages offered by this method comprise clearly defined negative deflection of the compound muscle action potential, lack of relevant volume conduction from adjacent muscles, reliability of amplitude criteria, absence of interfering stimulus artifacts, easy achievement of preactivation, and noninvasive recording by surface electrodes. In 43 healthy subjects transcranial magnetic stimulation evoked contralateral responses at a mean latency and me…
Age-associated changes in skeletal muscles and their effect on mobility: an operational diagnosis of sarcopenia.
2003
Sarcopenia, the reduction of muscle mass and strength that occurs with aging, is widely considered one of the major causes of disability in older persons. Surprisingly, criteria that may help a clinician to identify persons with impaired muscle function are still lacking. Using data from a large representative sample of the general population, we examined how muscle function and calf muscle area change with aging and affect mobility in men and women free of neurological conditions. We tested several putative indicators of sarcopenia, including knee extension isometric torque, handgrip, lower extremity muscle power, and calf muscle area. For each indicator, sarcopenia was considered to be p…
Mentally represented motor actions in normal agingII. The influence of the gravito-inertial context on the duration of overt and covert arm movements
2007
Here, we address the question of whether normal aging influences action representation by comparing the ability of 14 young (age: 23.6 +/- 2.1 years) and 14 older (age: 70.1 +/- 4.5 years) adults to mentally simulate arm movements under a varying dynamic context. We conducted two experiments in which we experimentally manipulated the gravity and inertial components of arm dynamics: (i) unloaded and loaded vertical arm movements, rotation around the shoulder joint, (ii) unloaded and loaded horizontal arm movements, rotations around the shoulder and elbow joints, in two directions (inertial anisotropy phenomenon). The main findings indicated that imagery ability was equivalent between the two…
Physical activity at age of 20-64 years and mobility and muscle strength in old age: a community-based study.
2012
Background. Physical activity in midlife has been related to lower mortality and better health in old age. The present study evaluated whether physical activity at age of 20–64 years was associated with mobility and muscle strength in old age. Methods. A random sample of 1,000 persons was extracted from all the ≥75-year-old people living in Kuopio, Finland, and 679 community-dwelling participants were included in the present analyses. Data on health status, ability to walk outside or 400 m, and physical activity level were obtained through structured interviews. Participants’ walking speed, grip strength, and knee extension strength were measured by physiotherapists. Relationship between ph…
Factors associated with maximal walking speed among older community-living adults.
2011
Background and aims: The relative contribution of different domains on walking speed is largely unknown. This study investigated the central factors associated with maximal walking speed among older people. Methods: Cross-sectional analyses of baseline data from the SCAMOB study (ISRCTN 07330512) involving 605 community-living ambulatory adults aged 75–81 years. Maximal walking speed, leg extensor power, standing balance and body mass index were measured at the research center. Physical activity, smoking, use of alcohol, chronic diseases and depressive symptoms were self-reported by standard questionnaires. Results: The mean maximal walking speed was 1.4 m/s (range 0.3–2.9). In linear regre…
Maximal force, force/time and activation/coactivation characteristics of the neck muscles in extension and flexion in healthy men and women at differ…
2002
This study examined the force production characteristics, activation/coactivation and endurance capacity of the neck extension and flexion muscles in healthy men (n=29) and women (n=28) divided into three age groups (18–26 years, 30–37 years and 45–55 years). Force and electromyography (EMG) measurements were performed during the maximal voluntary isometric extension and flexion actions. This was followed by an endurance test (ET; 60% force level of maximal voluntary contraction sustained until exhaustion), after which the force and EMG recordings were repeated. Men were both stronger and had higher values (P<0.001) for explosive force (rate of force development, RFD) than women in both act…
Heavy resistance exercise training and skeletal muscle androgen receptor expression in younger and older men
2010
Effects of heavy resistance exercise on serum testosterone and skeletal muscle androgen receptor (AR) concentrations were examined before and after a 21-week resistance training period. Seven healthy untrained young adult men (YT) and ten controls (YC) as well as ten older men (OT) and eight controls (OC) volunteered as subjects. Heavy resistance exercise bouts (5 × 10 RM leg presses) were performed before and after the training period. Muscle biopsies were obtained before and 1h and 48 h after the resistance exercise bouts from m.vastus lateralis (VL) to determine cross-sectional area of muscle fibers (fCSA) and AR mRNA expression and protein concentrations. No changes were observed in YC …
