Determinants of bronchial hyperresponsiveness in subjects with rhinitis.
2005
Subjects with rhinitis but without asthma may have coexisting bronchial hyperresponsiveness, although the reasons for this are uncertain. To evaluate the factors that determine BHR in rhinitis we examined 410 patients with symptomatic rhinitis with forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC) ≥ 80% of the predicted value. In all subjects a skin prick test (SPT) was performed, a determination of total serum IgE and an eosinophils count in the blood. Of the 410 subjects we found that 161 (39.3%) exhibited a methacholine PD20 of 800 mg or less (Group A), whereas 249 (60.7%) had a methacholine PD20 more of 800 mg (Group B). Despite the matched mean values for FEV…
Acute effects of dynamic stretching on mechanical properties result from both muscle-tendon stretching and muscle warm-up
2019
We investigated the acute effects of dynamic stretching on mechanical properties of plantar flexor muscles and tested the hypothesis that it would result from an interaction between muscle-tendon stretching and muscle warm-up. To test the stretching effect, dynamic stretching (DS) was compared to static stretching (SS). To test the warm-up effect, DS was compared to submaximal isometric muscle activity (SIMA) with similar contraction intensity. A control condition served as reference. These four conditioning activities were time matched (2×20s) and tested on separate days on 13 volunteers. Electrical neurostimulation was applied to investigate muscle mechanical properties (peak doublet torq…
Is It Good To Be Good? Dispositional Compassion and Health Behaviors
2018
Background Despite the documented importance of dispositional compassions for a range of health-related outcomes, its role in predicting health behaviors remains unclear. Purpose This study examined the associations between dispositional compassion and three domains of health behavior, including physical activity, alcohol use, and smoking. Methods The participants (N = 1,279–1,913) were from the Finnish population-based Young Finns study. We collected self-reports of compassion in 1997 and 2011 and health behaviors in 2001, 2007, and 2011. In addition, an objective pedometer measure of physical activity was collected in 2011. Linear and logistic regression models were fitted to estimate the…
Reliability of different models to assess heart rate recovery after submaximal bicycle exercise.
2011
Abstract Objectives : Different models to assess HR recovery have been developed but knowledge of their reliability is poor at different submaximal exercise intensities and recovery durations. Our aim was to determine the reliability of HR recovery after a test on a cycle ergometer. Design : Twenty-one healthy individuals performed a submaximal exercise at 65% and 80% HR max followed by passive recovery. The exercise was repeated (retest) within 2 weeks to assess reliability. Method : HR recovery was assessed by 8 models, based on monoexponential kinetics or absolute recovery (recovered HR at fix time points). Intraclass correlation coefficient (ICC) and standard error of measurement (SEM, …
The influence of high dose intravenous immunoglobulins on immunological and metabolic pattern in newly diagnosed type I diabetic patients
1990
In autoimmune disease the functional deficiency of T suppressor cells, also described in Type I diabetes, may be restored through immunoglobulin (Ig) infusion, which increases antigen phagocytosis, NK activity, cell clones and antibody anti-idiotype responses. Sixteen Type I diabetic patients were studied: eight were treated soon after the initial correction of disease-onset glycemic deterioration with intensive intravenous (i.v.) 7S Ig treatment (0.4 g/kg/BW) for 1 week and once per week for 6 months, whilst the remaining patients constituted the control group. All patients were evaluated during the study for metabolic and immunological parameters. A reduction in insulin requirement compar…
Postactivation potentiation in human knee extensors during dynamic passive movements.
2008
Purpose: Postactivation potentiation (PAP), i.e., the increase in twitch torque following a maximal voluntary conditioning contraction, has been shown to depend on muscle contractile conditions (e.g., muscle length). Few studies, however, have investigated the extent of twitch PAP under dynamic conditions in human subjects. Therefore, the aim of the present experiment was to test the twitch PAP during passive dynamic movements following isometric conditioning contractions on nine healthy men. Methods: Maximal twitches were evoked on the knee extensor muscles before and exactly 5 s after a 3-s conditioning maximal voluntary isometric contraction. PAP was determined at a constant joint angle …
Neurophysiological insights on flexibility improvements through motor imagery
2017
International audience; The efficacy of motor imagery (MI) practice to facilitate muscle stretching remains controversial and the underlying neurophysiological mechanisms unexplored. We evaluated the effects of MI practice during a sit-and reach task. Healthy participants were randomly assigned to a MI practice (n = 15) or Control (n = 15) group and completed 2 blocks of 5 sit-and-reach trials. During the first block (B1), participants performed 5 maximal stretching trials of 10s. During the second block (B2), trials were divided into two consecutive parts: i) reproducing the maximum performance of B1 (10s, B2 part 1), and ii) attempting to outperform the maximum performance of B1 (10s, B2 …
Fatigue and Recovery After High-Intensity Exercise Part II: Recovery Interventions
2004
The purpose of this study was to determine the effect of three types of recovery intervention to neuromuscular function after high-intensity uphill running exercise. The 20-min recovery interventions were (i) passive, (ii) active (running at 50 % of maximal aerobic speed), and (iii) low-frequency electromyostimulation. Evoked twitch and maximal voluntary contractions of knee extensor muscles (KE) and EMG of the vastus lateralis and vastus medialis were analysed immediately after the exercise, 10 min after the end of the recovery periods, and 65 min after the exercise (Post65). An all-out running test was also performed 80 min after the end of the fatiguing exercise. No significant differenc…
Passive exposure to speech sounds modifies change detection brain responses in adults
2019
In early life auditory discrimination ability can be enhanced by passive sound exposure. In contrast, in adulthood passive exposure seems to be insufficient to promote discrimination ability, but this has been tested only with a single short exposure session in humans. We tested whether passive exposure to unfamiliar auditory stimuli can result in enhanced cortical discrimination ability and change detection in adult humans, and whether the possible learning effect generalizes to different stimuli. To address these issues, we exposed adult Finnish participants to Chinese lexical tones passively for 2 h per day on 4 consecutive days. Behavioral responses and the brain's event-related potenti…
Is a female physical empowerment campaign effective in improving positive body image, motivation for physical activity, and physical activity behavio…
2022
This Girl Can is a campaign designed to empower women to increase physical activity. The campaign uses images/videos of women of diverse body weights/shapes, ages and ethnicities being physically active, emphasizing body functionality. First, we examined the effects of multi-session (N = 3) exposures to This Girl Can on body functionality, body appreciation and self-compassion (Study 1). Second, we explored if autonomous motivation for physical activity mediated effects of This Girl Can on physical activity (Study 2). Women (Study 1: N = 186, M (SD) age = 27.55 (14.01); Study 2: N = 153, M (SD) age = 28.31 (11.70)) were randomized to This Girl Can, or control videos/images depicting idealiz…
