Etäteknologiaa sisältävien liikunnallisten kuntoutusinterventioiden vaikuttavuus maksimaaliseen hapenottokykyyn : järjestelmällinen kirjallisuuskatsa…

2017

Hengitys- ja verenkiertoelimistön kunnon on todettu olevan yhteydessä useisiin sairauksiin ja eliniänodotteeseen. Etäteknologiaa sisältävillä interventioilla on todettu olevan yhteys fyysiseen aktiivisuuteen ja hengitys- ja verenkiertoelimistön kuntoon, mutta tutkittua vaikuttavuustietoa on vähän. Maksimaalinen hapenottokyky on yleisesti käytetty hengitys- ja verenkiertoelimistön kunnon mittari, ja se kuvaa hengitys- ja verenkiertoelimistön kykyä kuljettaa happea lihaksille. Tämän järjestelmällisen kirjallisuuskatsauksen tavoitteena oli selvittää etäteknologiaa sisältävien liikunnallisten kuntoutusinterventioiden vaikuttavuutta maksimaaliseen hapenottokykyyn. Kirjallisuushaku tehtiin (2000–…

The relationship between vigilance capacity and physical exercise: a mixed-effects multistudy analysis

2019

We thank to all the participants who took part in the experiment.

2019

Background: Physical inactivity is a major risk factor for nonalcoholic fatty liver disease (NAFLD). Exercise-based prevention interventions for improving cardiorespiratory fitness are a recommended complementary treatment for NAFLD. Achievement of minimally effective physical activity to improve cardiorespiratory fitness among patients typically involves high personal and financial expenses in face-to-face settings. We designed an eHealth approach for patients with NAFLD to improve the cardiorespiratory fitness and report the first results of the HELP (Hepatic Inflammation and Physical Performance in Patients With NASH [nonalcoholic steatohepatitis]) study. Objective: We aimed to assess th…

Effects of high-impact training and detraining on femoral neck structure in premenopausal women: a hip structural analysis of an 18-month randomized …

2013

Purpose: This study evaluated the training effects of an 18-month exercise intervention and subsequent 3.5-year follow-up on femoral neck structure in premenopausal women. Methods: Of 98 women who participated in this randomized controlled study, 84 (39 trainees and 45 controls) completed the 18-month intervention. At both 18 months and 3.5 years, dual-energy X-ray absorptiometry data on 22 trainees and 22 control participants (ages 35–45 y) were available for hip structural analysis. The section modulus (Z), cross-sectional area (CSA), and subperiosteal width at the femoral neck were analyzed. Lower-leg explosive power and estimated maximal oxygen uptake (Vo2max) were assessed by vertical…

Physical Fitness in Postmenopausal Women with Fibromyalgia

2007

The purpose of this study was to compare physical fitness and health-related quality-of-life between twenty-three postmenopausal women with fibromyalgia (age 58 +/- 3 years) and eleven healthy women (58 +/- 5 years). Aerobic fitness and isometric force of different muscle groups were measured. Functional performance was assessed by walking and stair-climbing times. Symptoms were assessed by visual analog scale and quality-of-life by RAND-36 questionnaire. Women with fibromyalgia had significantly lower isometric force in bilateral leg extensors (1285 vs. 1898 N), unilateral knee extensors (414 vs. 502 N) and flexors (197 vs. 235 N) than healthy women, but no differences were observed in for…

Effects of concurrent strength and endurance training on physical fitness and symptoms in postmenopausal women with fibromyalgia: a randomized controlled trial. Objective To examine the effectiveness of concurrent strength and endurance training on muscle strength, aerobic and functional performance, and symptoms in postmenopausal women with fibromyalgia (FM). Design Randomized controlled trial. Setting Local gym and university research laboratory. Participants Twenty-six women with FM. Intervention Progressive and supervised 21-week concurrent strength and endurance training. Main Outcome Measures Muscle …

The Relationship Between Maximal Exercise-Induced Increases in Serum IL-6, MPO and MMP-9 Concentrations

2012

The aim of this study was to test the hypothesis that exercise would induce inflammatory response characterized by increased pro-inflammatory cytokines - interleukin-6 (IL-6) and tumour necrosis factor-α (TNF-α), adhesion molecule, matrix metalloprotease-9 (MMP-9) and myeloperoxidase (MPO) levels. Additional aim was to elucidate the possible source of maximal exercise-induced increase in MMP-9 concentration. To examine our hypothesis, 26 professional male ice hockey players [age 25 ± 1 (mean ± SEM) years; BMI 25.8 ± 0.4 kg/m(2) ] performed an incremental bicycle test until exhaustion, when maximal oxygen consumption was recorded. Venous blood samples were collected 30 min before and 2 min a…

Immobilization increases interleukin-6, but not tumour necrosis factor-α, release from the leg during exercise in humans

2013

Data on interleukin-6 (IL-6) and tumour necrosis factor-α (TNF-α) release during acute exercise are not conclusive, and information is lacking about the impact of physical inactivity. Some studies have shown an increase, but others report no changes in IL-6 and TNF-α release during exercise. We have now studied the temporal relationship of leg IL-6 and TNF-α release before and during isolated two-legged exercise after 14 days of one-leg immobilization (IM) while the other leg served as the control (CON) leg. Fifteen healthy male subjects (mean ± SEM age, 23 ± 1 years; body mass index, 23.6 ± 0.7 kg m(-2); and maximal oxygen uptake, 46.8 ± 1.4 ml kg(-1) min(-1)) performed 45 min of two-legge…

AbstractBackgroundAdjuvant therapy may cause multiple sideeffects on long term health, including reduced cardiorespiratory fitness (CRF) in patients with breast cancer (1, 2). However, there is currently limited knowledge regarding the effect of different types of adjuvant cancer treatment on CRF in other cancer populations. The primary objective of the present study was to assess whether previously known correlates (age, diagnosis, initial CRF, physical activity level), type of adjuvant treatment and cancer-related fatigue were associated with changes in$$ \dot{V}{O}_2\mathit{\max} $$V̇O2maxin patients with breast, prostate or colorectal cancer.MethodsProspective study with two time points…
