An Optoelectronic System for Measuring the Range of Motion in Healthy Volunteers: A Cross-Sectional Study.

2019

Background and Objectives: Within the clinical evaluation of multiple pathologies of the lower limb, the measurement of range of motion (ROM) of its joints is fundamental. To this end, there are various tools, from the goniometer as a reference to more recent devices such as inclinometry-based applications, photo capture applications, or motion capture systems. This study aimed to assess the validity, intra-rater, and inter-rater reliability of the VeloFlex system (VS), which is a new camera-based tool designed for tracking joint trajectories and measuring joint ROM. Materials and Methods: Thirty-five healthy volunteers (16 females

Effects of muscle activation on shear between human soleus and gastrocnemius muscles

2015

Lateral connections between muscles provide pathways for myofascial force transmission. To elucidate whether these pathways have functional roles in vivo, we examined whether activation could alter the shear between the soleus (SOL) and lateral gastrocnemius (LG) muscles. We hypothesized that selective activation of LG would decrease the stretch-induced shear between LG and SOL. Eleven volunteers underwent a series of knee joint manipulations where plantar flexion force, LG, and SOL muscle fascicle lengths and relative displacement of aponeuroses between the muscles were obtained. Data during a passive full range of motion were recorded, followed by 20° knee extension stretches in both pass…

LE BÉNÉVOLAT POUR DES ÉVÉNEMENTS SPÉCIAUX: COMPARAISON ENTRE LA VALEUR ATTENDUE ET LA VALEUR PERÇUE

2016

Resumen: El fenómeno del voluntariado, como parte del sector no-lucrativo, puede ser estudiado desde una perspectiva de marketing como un comportamiento de consumo en el contexto de la realización de eventos especiales. En este estudio se busca explorar la dimensionalidad de la experiencia de ser voluntario en un megaevento religioso a través del concepto valor analizado con un enfoque diacrónico: pre-uso (valor esperado) vs. post-uso (valor percibido). Para ello, proponemos un estudio longitudinal sobre 711 voluntarios a través de dos análisis de componentes principales diferentes, antes y después del evento, sobre las mismas escalas de las dimensiones de valor. La estructura propuesta es …

Shorter recovery time following high-intensity interval training induced higher body fat loss among overweight women

2018

Background: High intensity interval training (HIIT) has been widely employed as an exercise protocol to reduce fat, and also in addition, interval recovery periods are the most important factors which can have great impact on weight loss. Therefore, the aim of this study was the evaluation of different recovery time between HIIT program on metabolic responses and weight loss in overweight women. Methods: Twenty-four overweight (BMI 29.5±3.5 kg/m2) volunteer women were randomly assigned into three groups (n=8/group) to study the effects of different recovery times: (group 1; HIIT with 60/60 activity-rest ratio (sec), group 2; HIIT with 60/30 activity-rest ratio (sec), and group 3 was set as …

Hobby, career or vocation? Meanings in sports coaching and their implications for recruitment and retention of coaches

2020

Rationale/Purpose: Traditional European sports clubs are facing increasing pressures to professionalise their services, while also encountering difficulties in the recruitment and retention of the coaching workforce. We used the concept of meaningful work to explore why coaching is worthwhile to coaches and how they have responded to the changes in the structural and narrative context of their work. \ud \ud Methodology: Drawing on narrative inquiry, we explored the various meanings and justifications that athletics (track and field) coaches assign to coaching in Finland and England. Twenty-three coaches (8 women, 15 men) aged 22 – 86 participated in narrative interviews that were analysed u…

Oxidative stress and antioxidant levels in patients with anorexia nervosa: A systematic review and exploratory meta-analysis.

2015

Objective To systematically review and meta-analyze oxidative stress and antioxidant markers in anorexia nervosa (AN). Methods Electronic PubMed search from database inception until 12/31/2013. Out of 1062 hits, 29 studies comparing oxidative stress/antioxidant markers between patients with AN and healthy controls (HCs) with a total of 1,729 participants (AN-=-895, HCs-=-834) were eligible. Data about oxidative stress and antioxidant markers, independent of their source, were extracted. We calculated random effects standardized mean differences (SMDs) as effect size measures for outcomes reported in ≥5 studies; others were summarized descriptively. Results Compared to HCs, AN patients showe…

Psychometric properties of the Assessment Tool for Perceived Agency (ATPA-22) - utility for the rehabilitation of young adults not in education, empl…

2020

Background: Promoting and supporting agency have been at the heart of the debate multidisciplinary. To promote self-awareness of young people’s agency and identify persons in need of support the Assessment Tool for Perceived Agency (ATPA-22) was developed. Aim: This study aims to evaluate the psychometric properties of the ATPA-22. Participants were young adults not in education, employment or training (NEETs) and students in higher education (HEI). Materials and methods: The main data analysis was implemented by Many Faceted Rasch (MFR) analysis. Results: The ATPA-22 items defined a unidimensional construct with reasonable internal consistency and separation ability. The ATPA-22 was capabl…

Social engagement from childhood to middle age and the effect of childhood socio-economic status on middle age social engagement: results from the Na…

2016

ABSTRACTSocial engagement has powerful effects on wellbeing, but variation in individual engagement throughout the lifecourse is wide. The trajectories may differ by gender and be affected by socio-economic status (SES). However, long-term development of social engagement is little studied and the effect of childhood SES on later-life social engagement remains obscure. We aimed to describe the social engagement development from childhood to middle age by gender and test the effect of childhood SES on middle age social engagement. Data (N=16,440, 51.3% male) are drawn from the on-going National Child Development Study, following British babies born in 1958. Social engagement was measured by …

Vapaaehtoistyöntekijöiden kokemuksia vastavuoroisuudesta ikääntyneiden ihmisten vapaaehtoistyössä

2019

Sosiaalisen vaihdon teorian mukaan vastavuoroisuus on tärkeää ikääntyneiden ihmisten suhteissa. Vapaaehtoistyössä vastavuoroisuus on oleellista, mutta sitä ei ole juuri tutkittu eläkeikäisten vapaaehtoistyöntekijöiden kannalta. Tämän tutkimuksen tarkoituksena on selvittää, kuinka eläkeikäiset vapaaehtoistyöntekijät kokevat vastavuoroisuuden vapaaehtoistyössä. Kolme kuukautta kestäneen toimintajakson aikana vapaaehtoistyöntekijät auttoivat liikkumiskyvyn ongelmista kärsiviä ikäihmisiä osallistumaan kodin ulkopuoliseen toimintaan osana Vapaaehtoistyö, ulkoliikunta ja vanhusten hyvinvointi (VAU) -tutkimushanketta. Tämän laadullisen osatutkimuksen 17 osallistujaa olivat 61 - 72-vuotiaita. Tutki…
