Physical activity - an important preanalytical variable

2014

The concentration of several biochemical and hematological biomarkers is strongly influenced by a number of preanalytical variables. Several lines of evidence attest that short, middle, and long-term exercise, as well as the relative intensity of physical effort (from mild to strenuous), may influence a broad array of laboratory variables. The amount of extracellular release and clearance from blood of most of these biomarkers is markedly influenced by the biological characteristics of the molecule(s), level of training, type, intensity and duration of exercise, and time of recovery after training. It is hence noteworthy that test results that fall outside the conventional reference ranges …

P125 Internet-based exercise therapy in patients with systemic lupus erythematodes – systemic lupus erythematodes exercise program (SLEEP)

2020

Background The SLEEP study examines the effect of an exercise therapy against a control group with TAU therapy (Treatment as usual) in SLE to identify the effect of regular physical activity on muscular development. Furthermore, we investigate the effect of physical activity on disease activity and especially on fatigue syndrome. Molecular biological markers such as cfDNA and exosomes also detect the degree of the prostration of the patients. Methods Thirty SLE patients with laboratory as well as clinically stable status were included. The intervention group initially consisted of 24 patients, of which 12 were aerobically and 12 anaerobically active. In contrast, eight patients were include…

Alterations of Neuromuscular Function After Prolonged Running, Cycling and Skiing Exercises

2004

It is well known that impairment of performance resulting from muscle fatigue differs according to the types of contraction involved, the muscular groups tested and the exercise duration/intensity. Depending on these variables, strength loss with fatigue can originate from several sites from the motor cortex through to contractile elements. This has been termed 'task dependency of muscle fatigue'. Only recently have studies focused on the origin of muscle fatigue after prolonged exercise lasting 30 minutes to several hours. Central fatigue has been shown to contribute to muscle fatigue during long-distance running by using different methods such as the twitch interpolation technique, the ra…

Mindful Exercise (Baduanjin) as an Adjuvant Treatment for Older Adults (60 Years Old and Over) of Knee Osteoarthritis: A Randomized Controlled Trial

2020

Background. The postural stability is a major factor that helps prevent developing knee osteoarthritis with aging. The aim of this study was to investigate the effects of Baduanjin qigong on postural control and physical function in older adults with knee osteoarthritis. Methods. Fifty-six individuals over 60 years of age with knee osteoarthritis were randomly assigned to either an experimental group (n = 28) or a control group (n = 28). Participants in the experimental group received a 12-week Baduanjin training, while those in the control group did not receive any additional physical exercise during the study period. The postural control was quantified by perimeter and ellipse area of cen…

Effects of strength and endurance training on thigh and leg muscle mass and composition in elderly women

1995

The effects of 18 wk of intensive strength and endurance training on knee extensor, knee flexor, and lower leg muscle mass and composition were studied in 76- to 78-yr-old women. Muscle cross-sectional area (CSA), lean tissue CSA, and relative proportion of fat were determined using computed tomography. The strength-trained women increased their total muscle lean tissue CSA of the thigh (1.5%; P = 0.035), quadriceps CSA (4.5%; P = 0.021), quadriceps lean tissue CSA (5.8%, P = 0.009), and mean Hounsfield unit of the lower leg muscles (11.2%; P = 0.035) compared with the changes that occurred in the control group during the experiment. The change in quadriceps lean tissue CSA because of the …

Quantitative ultrasonography of muscle: Detection of adaptations to training in elderly women

1996

Abstract Objective: To develop quantitative ultrasonography in studying the adaptation of quadriceps muscle mass and composition to short-term physical training and rehabilitation in elderly women. Design: Randomized control trial. Setting: Measurements in a research laboratory and training in a fitness center and sports hall. Participants: Forty-two women, aged 76 to 78 years, with no indications against intensive physical exercise, randomly assigned to strength ( n = 16), endurance ( n = 15), and control ( n = 11) groups. Twelve subjects from the strength, 12 from the endurance, and 11 from the control group completed the study. Intervention: Supervised physical training 3 times a week fo…

Serum concentrations of collagen degrading enzymes and their inhibitors after downhill running

2001

In the present study the release of proteins degrading extracellular matrix compounds to circulation was measured after damaging exercise in humans. Muscle damage was induced by downhill running; furthermore, the exercise was performed at both cold temperature (5 degrees C) and room temperature (22 degrees C) to study also the possible effect of environmental temperature on serum concentrations of matrix metalloproteinases MMP-2 and MMP-9, tissue inhibitors of metalloproteinases TIMP-1 and TIMP-2, and MMP-2/TIMP-2 complex, and muscle damage monitored by serum creatine kinase measurements. Results were compared with those obtained from patients having rhabdomyolysis, myositis and Becker musc…

AB1367-HPR EFFECTIVENESS OF THE HYPERBARIC TREATMENT ON THE PERCEIVED PAIN, FATIGUE AND FUNCTIONALITY OF WOMEN WITH FIBROMYALGIA

2019

Background Fibromyalgia (FM) is a chronic pain syndrome accompanied by other symptoms such as fatigue or altered functionality1. One of the most common non-pharmacologic treatment is physical exercise because of its known positive influence on pain as a consequence of the physical condition improvement. 2 However, they use to present a lack of adherence to this type of therapeutic programs may be attributable to post-exercise pain 3. For this reason, alternative approaches that do not involve physical efforts, such as hyperbaric therapy, may be effective to reduce pain, fatigue or functionality in women with FM.4 Objectives To compare the effectiveness of hyperbaric therapy and physical exe…

Free Radicals and Antioxidants in Physical Exercise

1998

The beneficial effects of exercise are well documented. Indeed, it ameliorates diabetes mellitus, improves the plasma lipid profile, increases bone density and may help to lose weight. However, as stated in the old medical saying “the beneficial effects of exercise are lost with exhaustion”. It has been known for some time that exhaustive exercise causes muscle soreness, induces an elevation of cytosolic enzyme activities in blood plasma and may be harmful. In the last decade a considerable amount of information concerning production of free radicals in exhaustive exercise has been obtained. An international symposium took place in Valencia, Spain in 1993 and a book was published on the sub…
