Long Term Leisure Time Physical Activity Has a Positive Effect on Bone Mass Gain in Girls

2009

The purpose of this 7-year prospective longitudinal study was to examine whether the level and consistency of leisure-time physical activity (LTPA) during adolescence affected the bone mineral content (BMC) and bone mineral density (BMD) attained at early adulthood. The study subjects were 202 Finnish girls who were 10 to 13 years of age at baseline. Bone area (BA), BMC, and BMD of the total body (TB), total femur (TF), and lumbar spine (L2–L4) were assessed by dual-energy X-ray absorptiometry (DXA). Scores of LTPA were obtained by questionnaire. Girls were divided into four groups: consistently low physical activity (GLL), consistently high (GHH), and changed from low to high (GLH) and fro…

The pain threshold of high-threshold mechanosensitive receptors subsequent to maximal eccentric exercise is a potential marker in the prediction of D…

2017

Background Delayed-onset muscle soreness (DOMS) refers to dull pain and discomfort in people after participating in exercise, sport or recreational physical activities. The aim of this study was to detect underlying mechanical thresholds in an experimental model of DOMS. Methods Randomised study to detect mechanical pain thresholds in a randomised order following experimentally induced DOMS of the non-dominant arm in healthy participants. Main outcome was the detection of the pressure pain threshold (PPT), secondary thresholds included mechanical detection (MDT) and pain thresholds (MPT), pain intensity, pain perceptions and the maximum isometric voluntary force (MIVF). Results Twenty volun…

Strength training in treatment of chronic neck pain

2022

Background: Chronic non-specific neck pain is common in modern industrialized countries causing suffering, disability and considerable economical losses for individuals and society. Treatment is commonly advice for stretching and strength exercises in primary health care. However, if improvements are not satisfactory, patients may seek specialist care. The purpose of this study was to evaluate the effectiveness of multimodal rehabilitation in treatment of chronic neck pain. Methods: The study group comprised of 56 patients with chronic neck pain, who participated rehabilitation for three weeks and one-week follow-up period after eight months at an inpatient rehabilitation facility. The aim …

A classification of motivation and behavior change techniques used in self-determination theory-based interventions in health contexts

2020

While evidence suggests that interventions based on self-determination theory have efficacy in motivating adoption and maintenance of health-related behaviors, and in promoting adaptive psychological outcomes, the motivational techniques that comprise the content of these interventions have not been comprehensively identified or described. The aim of the present study was to develop a classification system of the techniques that comprise self-determination theory interventions, with satisfaction of psychological needs as an organizing principle. Candidate techniques were identified through a comprehensive review of self-determination theory interventions and nomination by experts. The study…

Decreasing muscle performance associated with increasing disease activity in patients with rheumatoid arthritis

2018

Objectives Increasing evidence suggests that inflammation has a detrimental effect on muscle strength. Our objective was to analyse the association between muscle performance and different disease activity levels in patients with rheumatoid arthritis (RA). Method A total of 199 consecutive outpatients were subject to cross-sectional assessment. Measurements of grip strength, endurance of the upper and lower limbs and trunk strength were combined as a muscle performance composite score (MPCS), using a standardised method. The disease activity for 28 joints (DAS28), radiographs of small joints (Larsen score), rheumatoid factor, body mass index (BMI), comorbidities and anti-rheumatic drugs wer…

Interactive multiobjective optimization for finding the most preferred exercise therapy modality in knee osteoarthritis

2022

Abstract Background There are no explicit guidelines or tools available to support clinicians in selecting exercise therapy modalities according to the characteristics of individual patients despite the apparent need. Objective This study develops a methodology based on a novel multiobjective optimization model and examines its feasibility as a decision support tool to support healthcare professionals in comparing different modalities and identifying the most preferred one based on a patient’s needs. Methods Thirty-one exercise therapy modalities were considered from 21 randomized controlled trials. A novel interactive multiobjective optimization model was designed to characterize the effic…

Reasons for Exercise Inventory koulukyselyssä : mittarin reliabiliteetti- ja rakennevaliditeettitarkastelua

2005

Tässä artikkelissa raportoidaan aikuisille kehitetyn Reasons for exercise inventory:n (REI) käyttökokeilua yläkoululaisilla. Mittaria esitestattiin WHO-Koululaistutkimuksen vuoden 2006 kyselyä varten osana esi- ja luotettavuustutkimusta, joka toteutettiin Itä- ja Länsi-Suomen lääneissä helmikuussa 2005. Oppilaat täyttivät kaksi samansisältöistä kyselyä kahden viikon välein. REI-mittarin väittämiin vastasi 194 seitsemäs- ja yhdeksäsluokkalaista peruskoululaista. REI-mittarin pysyvyyttä arvioitiin testi-uusintatesti-korrelaatioiden (Intraclass-korrelaatiokerroin, Spearmanin järjestyskorrelaatio, Pearsonin tulomomenttikorrelaatio) avulla. Pääkomponenttianalyysin avulla saaduista liikuntasyiden…

Changes in Fat Oxidation and Body Composition after Combined Exercise Intervention in Sedentary Obese Chinese Adults.

2022

(1) Background: Evidence suggests that aerobic exercise and high-intensity interval training (HIIT) might increase fat oxidation and reduce fat. However, limited research has examined the effects of combining progressive aerobic exercise and HIIT interventions in sedentary adults with overweight and obesity, and differences in its effects between men and women remain unclear. The purpose of this study was to investigate the effects of combined progressive aerobic exercise and HIIT (CAEH) on fat oxidation and fat reduction in sedentary Chinese adults and compare sex differences in sedentary adults after seven weeks. (2) Methods: Eighty-four sedentary obese adults were enrolled and allocated …

Power Loading-Induced Fatigue is Influenced by Menstrual Cycle Phase

2022

Purpose To examine the effects of fatiguing power-loading on neuromuscular properties, force production, and metabolic capacities during four phases of the menstrual cycle (MC); menstruation (M), mid-follicular (mid FOL), ovulation (OV), and mid-luteal (mid LUT). Methods Sixteen eumenorrheic women performed sessions of maximal explosive leg press (2x10 at 60%1RM load with 2 min recovery between sets). Serum hormones and neuromuscular responses were measured. Results The loading protocol significantly decreased power (between -14.2% and -12.5%; p < 0.001) and maximal force production (between MVC; -15.0% and -7.8%; p < 0.001–0.05), while decreasing activation level (between AL; -6.9% and -2.…
