Device-Based Measures of Sedentary Time and Physical Activity Are Associated With Physical Fitness and Body Fat Content
2020
Introduction/Purpose: Physical activity and sedentary time may associate with physical fitness and body composition. Yet, there exists some observational studies that have investigated the associations of device-based measures of sedentary time and physical activity (PA) with cardiorespiratory fitness (CRF) and body composition but associations with muscular fitness (MF) are less studied.Methods: Objective sedentary time and physical activity was measured by a hip worn accelerometer from 415 young adult men (age: mean 26, standard deviation 7 years). Cardiorespiratory fitness (VO2max) (CRF) was determined using a graded cycle ergometer test until exhaustion. Maximal force of lower extremiti…
Plantar pressure and foot temperature responses to acute barefoot and shod running
2015
AbstractPurpose. Increased contact pressure and skin friction may lead to higher skin temperature. Here, we hypothesized a relationship between plantar pressure and foot temperature. To elicit different conditions of stress to the foot, participants performed running trials of barefoot and shod running. Methods. Eighteen male recreational runners ran shod and barefoot at a self-selected speed for 15 min over different days. Before and immediately after running, plantar pressure during standing (via a pressure mapping system) and skin temperature (using thermography) were recorded. Results. No significant changes were found in plantar pressure after barefoot or shod conditions (p > 0.9). …
Softening of Silica Filled Styrene-Butadiene Rubber under Uniaxial Cyclic Loading
2016
Stress-strain behaviour of silica filled styrene-butadiene rubber showed strong hysteresis and cyclic softening, while these effects were almost negligible for the neat rubber. Significant Mullins effect occurs between the first and second loading cycles, whereupon samples reach their steady state after four repeated cycles. The degree of softening increases with volume content of silica characterizing the softening effect as a breakdown of the filler-formed microstructure defined by both, specific interactions in the filler associations and between the filler and rubber matrix. Contribution of different damage mechanisms to the total energy losses on different stages of extension was estim…
Volume Changes in Filled Rubber Under Uniaxial Cyclic Loading
2011
Styrene-butadiene rubber, neat and filled with different silica content was investigated under uniaxial cyclic loading under a constant crosshead speed, with increasing deformation amplitude in subsequent loading cycles. Rubber was investigated in order to evaluate the reversibility of structure rearrangements, occurring in rubber when subjected to cyclic loading. Volume uniformly increases with growing strain and shows hysteresis at unloading. After complete unloading, no residual strain changes are observed. These data are in good conformity with the data of density measurements, which were made on specimens before and after the tests. By correlating data, obtained from volume changes and…
Corporeità e formazione: il ruolo della Danza Movimento Terapia nei corsi universitari di Scienze dell'Educazione
2019
A partire da una riflessione sulle specificità professionali degli educatori e dall'intreccio della dimensione personale con quella professionale nelle professioni educative, Il saggio tratta della necessità di adottare una nuova prospettiva formativa, che consideri l'unità mente-corpo, la dimensione artistica e la riflessività nei processi di apprendimento dei futuri educatori. Esplicita quindi le ragioni di un apprendimento dall'esperienza e sottolinea l'importanza della dimensione di gruppo, approfondendo infine le peculiarità della Danza Movimento terapia e l'efficacia di un percorso laboratoriale che utilizzi le sue metodologie Reflecting about educators professional specificities and …
Leptin plasma levels in patients undergoing prostate biopsy. a preliminary study in 50 patients
2013
Introduction/Aim: To reduce the number of negative prostate biopsies and to detect clinical significant prostate tumors in patients with elevated serum PSA represent major challenges in urological oncology. Prostate tumors diagnosed in patients with elevated Body Mass Index (BMI) show higher Gleason score and more aggressive biological behavior than those diagnosed in normal population (1). Elevated plasma levels of leptin and other adipose tissue derived factors (adipokines), are evident in obese men (2). Many studies have investigated the role of leptin as a putative molecular mediator between obesity and prostate cancer with contradictory results. Also in normal or overweight (BMI <30) m…
Early-Life Factors as Predictors of Age-Associated Deficit Accumulation Across 17 Years From Midlife Into Old Age
2022
Abstract Background Early-life exposures have been associated with the risk of frailty in old age. We investigated whether early-life exposures predict the level and rate of change in a frailty index (FI) from midlife into old age. Methods A linear mixed model analysis was performed using data from 3 measurement occasions over 17 years in participants from the Helsinki Birth Cohort Study (n = 2 000) aged 57–84 years. A 41-item FI was calculated on each occasion. Information on birth size, maternal body mass index (BMI), growth in infancy and childhood, childhood socioeconomic status (SES), and early-life stress (wartime separation from both parents) was obtained from registers and health ca…
Correlation between body size and longevity : New analysis and data covering six taxonomic classes of vertebrates
2023
Large bodied species are known to live longer than small bodied species. However, it is less clear whether the positive correlation varies across taxa. In this short communication, we combine data entries from literature and databases on body mass and maximum life span for 3722 species covering taxonomic Classes Chondrichthyes, Teleostei, Amphibia, Reptilia, Aves, and Mammalia. We then analyse the log(maximum life span) – log(body mass) relationship using generalized linear model with nested random intercepts and slopes for Class/Order/Family. Our analyses generally demonstrate the positive longevity – body mass relationship but also reveal that slopes and intercepts differ slightly among a…
Discovering the embodiment of the group fitness instructor : case study of group fitness instructors of Fysioline Fressi
2017
Group fitness instructors are often portrayed as physically toned and fit with healthy lifestyles overall. The aim of a group fitness class is to help participants exercise in a desired manner with motivational coaching. Instructing a class requires a combination of coordination, anticipation and moving in-line with the music. The instructor is often situated in front of the class, making the body as visible as possible. The body is also the instructor’s single most important tool at work, which is used to show movements and non-verbal messages. The complexity of the task creates an interesting platform to research the experience of embodiment and hopefully offer insight in to what the body…
Multicompartmental Lipopolyplex as Vehicle for Antigens and Genes Delivery in Vaccine Formulations
2021
Vector design and its characterization is an area of great interest in current vaccine research. In this article, we have formulated and characterized a multicompartmental lipopolyplex, which associates multiple liposomes and polyplexes in the same complex. These particles allow the simultaneous delivery of lipid or water-soluble antigens associated with genes to the same cell, in much higher amounts than conventional lipopolyplexes. The vector characterization and optimization were carried out using liposomes with entrapped carboxyfluorescein and adapted electrophoretic assays. Two types of lipopolyplexes (containing hydrophilic or lipophilic antigens) were employed to evaluate their inter…
