Peripheral Nerve Responses to Muscle Stretching: A Systematic Review
2021
Stretching is commonly used to increase range of motion and flexibility. Therefore, investigations are usually oriented towards the muscle-tendon unit. Limited evidence exists regarding potential effects of stretching on peripheral nerves which lie within muscles. The objective of this investigation will be to elucidate the responses of peripheral nerves to stretching. A literature search was performed using the following databases: Scopus, NLM Pubmed and ScienceDirect. Studies regarding the effects of stretching protocols on responses of peripheral nerves were retrieved for investigation. The NHLBI tool was used for quality assessment. Outcomes included nerve stiffness, nerve displacement,…
Mechanical Coupling Between Muscle-Tendon Units Reduces Peak Stresses
2017
The presence of mechanical linkages between synergistic muscles and their common tendons may distribute forces among the involved structures. We review studies, using humans and other animals, examining muscle and tendon interactions and discuss the hypothesis that connections between muscle bellies and within tendons may serve as a mechanism to distribute forces and mitigate peak stresses. peerReviewed
Contribution and effectiveness of ski and pole forces in selected roller skiing techniques on treadmill at moderate inclines
2023
BackgroundMost of the studies about the effects of incline on cross-country skiing are related to the metabolic efficiency. The effective skiing biomechanics has also been indicated to be among the key factors that may promote good performance. The aims of this study were to provide biomechanical characteristics and investigate the relative contribution and effectiveness of ski and pole forces in overcoming the total external resistance with double poling (DP) and Gear 3 (G3) techniques at varying moderate uphill inclines.Methods10 male cross-country skiers participated in this study. Custom-made force measurement bindings, pole force sensors, and an 8-camera Vicon system were used to colle…
Effects of Different Sports Shoes and Bare Feet on Static and Dynamic Balance In Healthy Females: A Randomized Clinical Trial
2022
Static and dynamic balance can be influenced by many factors. However, there is limited evidence regarding the effects that shoe sole hardness may have on balance. The aim of our study was to investigate effects of different sports shoes and bare feet on static and dynamic balance in healthy female individuals. Seventeen female participants were included in our study. All participants were assessed with bare feet, hard-support sports shoes and soft-foam sports shoes. The order of the assessment for each participant was randomly determined using an online random allocation software. The SportKAT 3000® device was used to assess dynamic double feet, static double feet, dominant foot and non-do…
Retos y oportunidades de la tecnología móvil en la educación física (Challenges and opportunities of mobile technology in physical education).
2019
La educación física (EF) y su profesorado están llamados a seguir procesos de inmersión digital, voluntarios o involuntarios, asociados al consumo masivo de medios y servicios digitales y a las demandas de la sociedad y de la institución educativa. El uso de tecnología, especialmente la móvil, social y ubicua, se generaliza personal y profesionalmente, aunque la escuela sigue sin encontrarle acomodo. Reconoce su potencial didáctico, pero no logra alcanzarlo. En la EF el uso de tecnologías tradicionales y fijas han demostrado su utilidad en la fase preactiva y postactiva del acto didáctico, sin embargo, los aprendizajes en movilidad propios de la fase activa, aconsejan explorar alternativas …
The Relationship between Motivational Climate and Personal Treatment Satisfaction among Young Soccer Players in Norway: The Moderating Role of Suppor…
2020
Motivational climate and coach-behaviour seem important to understand sport involvement and participation. However, less is known about the potential interaction between these facets, and how it relates to athlete satisfaction. This study&rsquo
Validity and Reliability of a New Optoelectronic System for Measuring Active Range of Motion of Upper Limb Joints in Asymptomatic and Symptomatic Sub…
2019
The aim of this study was to evaluate the validity of the Veloflex infrared dynamic angle-meter (Veloflex-IDA) and the intra- and inter-rater reliability when measuring the ranges of motion (ROMs) of the upper limb joints. Thirty-five healthy and 20 symptomatic participants were evaluated. Twelve upper limb movements were measured in two sessions with the Veloflex-IDA, which is a device composed of a camera that tracks the trajectory of retro-reflective markers. In addition, a goniometer was used in the first session to evaluate concurrent validity. Validity and agreement were evaluated by Pearson correlation coefficient (r) and Bland&ndash
Predictive Strength of Physical Education-Centered Physical Literacy Indicators on Physical Activity
2021
This study examined the predictive strength of selected physical education (PE)-centered physical literacy indicators on elementary school students’ accelerometer-measured moderate to vigorous intensity physical activity (PA). The study was a cross-sectional study with a sample of 450 Finnish children (M = 11.26 [0.32]; nfemales = 194; nmales = 256). Data on a set of predictor variables (motor competence, in-class PE moderate- to vigorous-intensity PA [MVPA], health-related fitness, and PE motivation and enjoyment) and total MVPA as a single outcome variable were collected. The entire model explained almost 30% of MVPA (R2adj = .298). Cardiorespiratory endurance (β = 0.42, 95% confidence in…
Development of accelerometer-based light to vigorous physical activity in fitness profiles of school-aged children.
2021
This study examined the developmental trajectories of light (LPA) and moderate-to-vigorous physical activity (MVPA) in fitness profiles derived from motor competence, perceived motor competence, health-related fitness, and MVPA behaviour. Locomotor, stability, and object-control skills, muscular and cardiovascular fitness, and physical activity were assessed in 510 (girls 285, boys 225) Finnish school-aged children (Mage = 11.26 ± .33 years) over three years. Physical activity was measured using hip-mounted accelerometers. Fitness profiles were identified using latent profile analysis and the development of physical activity levels across four assessments was analysed with latent growth cur…
Finnish students’ enjoyment and anxiety levels during fitness testing classes
2020
Background: Fitness testing is a commonly applied learning and teaching practice implemented in both secondary and elementary school physical education (PE). Many teachers believe that by using a variety of different tests, they are able to provide students with feedback regarding their fitness status, and furthermore, increase students’ willingness to be physically active later in their lives. However, empirical evidence concerning students’ affective responses during fitness testing classes is limited. Purpose: The primary aim of the study was to investigate whether students’ perceptions of enjoyment and anxiety differed between two different types of fitness testing classes and PE in gen…
