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,…
Propulsion Calculated by Force and Displacement of Center of Mass in Treadmill Cross-Country Skiing
2022
This study evaluated two approaches for estimating the total propulsive force on a skier’s center of mass (COM) with double-poling (DP) and V2-skating (V2) skiing techniques. We also assessed the accuracy and the stability of each approach by changing the speed and the incline of the treadmill. A total of 10 cross-country skiers participated in this study. Force measurement bindings, pole force sensors, and an eight-camera Vicon system were used for data collection. The coefficient of multiple correlation (CMC) was calculated to evaluate the similarity between the force curves. Mean absolute force differences between the estimated values and the reference value were computed to evalua…
Compulsive exercise as a mediator between clinical perfectionism and eating pathology
2017
The aim of this study was to examine whether compulsive exercise mediates the relationship between clinical perfectionism and eating pathology, based on the cognitive behavioral model of compulsive exercise. Participants were 368 adults who participated regularly in sport/exercise and completed online measures of perfectionism, compulsive exercise and eating disorders. In support of the well-established link between perfectionism and eating disorders, clinical perfectionism predicted eating pathology both directly and indirectly mediated by compulsive exercise. In addition, there were also direct effects of clinical perfectionism on the avoidance/rule-driven behavior, weight control, and mo…
LEARNING THE VALUE OF TIME IN PHYSICAL EDUCATION
2021
El presente artículo analiza las prácticas pedagógicas de la Educación Física de un contexto específico para describir cómo promueven el aprendizaje del tiempo. A partir de una etnografía se obtienen las actividades propuestas por el profesorado de Educación Física de una escuela de Meliana, en Valencia (España). Se recogen 82 tareas motrices que son analizadas y contextualizadas en el marco educativo. Los resultados, a la luz de las ciencias de la educación, muestran una tendencia a realizar tareas sin memoria de resultado en las que no existe un final marcado por las reglas y, en menor tiempo, actividades con memoria en las que los participantes se clasifican en función del desenlace. La …
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…
Physical literacy in Europe : The current state of implementation in research, practice, and policy
2023
BACKGROUND/OBJECTIVE: The holistic concept of physical literacy (PL) embraces different person-centered qualities (physical, cognitive, affective/psychological) necessary to lead physically active lifestyles. PL has recently gained increasing attention globally and Europe is no exception. However, scientific endeavors summarizing the current state of PL in Europe are lacking. Therefore, the goal of this study was to comprehensively assess and compare the implementation of PL in research, policy, and practice across the continent.METHODS: We assembled a panel of experts representing 25 European countries. Employing a complementary mixed-methods design, the experts first prepared reviews abou…
Implementation of group based exercises by peer instructors : a feasibility study in the elderly population
2009
Background and purpose of the study By the year 2035, the number of persons ≥ 75 years of age will have doubled in Finland. There is convincing evidence for the importance of regular, moderate intensity physical activity for public health gain. Exercise programs need to be developed that can reach the elderly effectively, make optimal use of available resources and are cost effective, thus augmenting state services. The purpose of this study is to evaluate the process and feasibility of a program where peer instructors were educated to implement group based exercises in local pensioner’s societies in Finland. Research methods and data 48 peer instructors (>75 years of age) from 20 societies…
Function and Fiber-Type Specific Distribution of Hsp60 and αB-Crystallin in Skeletal Muscles: Role of Physical Exercise
2021
Simple Summary Skeletal muscle represents about 40% of the body mass in humans and it is a copious and plastic tissue, rich in proteins that are subject to continuous rearrangements. Physical exercise is considered a physiological stressor for different organs, in particular for skeletal muscle, and it is a factor able to stimulate the cellular remodeling processes related to the phenomenon of adaptation. All cells respond to various stress conditions by up-regulating the expression and/or activation of a group of proteins called heat shock proteins (HSPs). Although their expression is induced by several stimuli, they are commonly recognized as HSPs due to the first experiments showing thei…
Is the Short and Fast Step Test a safe and feasible tool for exploring anaerobic capacities of individuals with coronary heart disease in clinical pr…
2021
Background While its importance in daily living, the anaerobic metabolism is not taken into account in clinical practice. The lack of validated functional performance tests for patients with chronic disabilities may explain this defect. In this context, the Short and Fast Step Test (SFST) was recently developed and validated in healthy volunteers. Aim The purpose of this study was to investigate the safety, feasibility and reliability of the SFST, a functional test exploring anaerobic metabolism in coronary patients during cardiac rehabilitation. Design This study was a monocentric prospective study. Settings This study took place in the rehabilitation center of the University Hospital Cent…
Maximal isometric muscle strength and functional ability in daily activities among 75-year-old men and women
2007
The purpose of this study was to analyze whether functional ability in daily activities among 75-year-old men and women is predicted by physical activity, isometric muscle strength and simple function tests. In this representative sample of a general population of 405 75-year-olds, isometric muscle strength and functional ability in daily activities were closely related (odds ratio of disability 1.2–2.1), stressing the importance of strength in the truncus, proximal and distal muscle groups for daily activities. There were strong correlations between physical activity, isometric muscle strength as well as simple function tests and ability to manage daily activities. Those with even light ph…
