Optimal inter-stimulus interval for interpolated twitch technique when using double pulse stimulation

2013

Interpolated twitch technique is a method frequently used to assess voluntary activa- tion. This method uses electrically evoked twitch superimposed on the voluntary activi- ty and its comparison with the twitch in rested muscle i.e. control twitch, to evaluate completeness of muscle activation. The purpose of this study was to investigate the ef- fect of interval in paired stimulation on control twitch in young and elderly individuals with bent and flexed knee positions. Supramaximal electrical stimulation consisted of one single stimulus and eight paired stimulation with intervals from 5 to 40ms, with increments of 5ms. In evoked twitches normalized peak torque amplitude (NPT), time to pe…

Quality certifications’ impact on wine industry assets performance

2020

This study analyses the impact of third-party voluntary certifications on the asset of wineries operating in the Southern Italian regions. The study carried out both quantitative and qualitative approaches, with data extracted from the AIDA Bureau van Dijk International Database (including performance indicators). The analysed sector belongs to 11.02 ‘Manufacture of wine from grape’ of the Statistical classification of economic activities in the European Community (NACE). The econometric elaboration (regression) was carried out by means of STATA software 14. Comparing certified and no certified wineries, results show a better asset performance of certified wineries, confirmed by a positive …

Physical Fitness and Body Anthropometrics Profiles of the Female Recruits Entering to Voluntary Military Service

2019

Introduction. The physical fitness of male conscripts has decreased, and body mass increased during the last few decades, especially in Nordic countries. However, limited research-based reports are available concerning the physical fitness profiles of female recruits. Therefore, the purpose of this study was to investigate changes in physical fitness and body composition of female recruits entering voluntary Finnish military service between the years 2005 and 2015. Materials and methods. Data were collected from the initial fitness tests performed in military units during the first two weeks of military service. A total of 3875 healthy female recruits (19.9±2.1 yr.) participated in the fitn…

Reciprocity, matching and conditional cooperation in two public goods games

2005

Previous experimental and empirical evidence has identified social preferences in the voluntary provision of public goods. A number of competing models of such preferences have been proposed. We provide evidence for one model of behavior in these games, reciprocity (or matching, or conditional cooperation). Consistent with previous research, we find that participants in the voluntary contribution mechanism attempt to match the contributions of others in their group. We also examine participants in a related game with different equilibria, the weakest-link mechanism. Here, in contrast, participants contribute so as to match the minimum contribution of others in their group.

El sector no lucrativo desde el enfoque de la elección pública: Cuando la oferta no lucrativa de bienes públicos es el resultado de decisiones emanad…

2001

The voluntary supply of collective goods by nonprofit institutions has deserved little attention in the Public Choice literature, and the clasical nonprofits approach does not consider nonprofits supply as a collective decision, although individuals, either as consumers or as donors, are in the center of their theoretical constructs. In this paper we hypothesize that voluntary nonprofits' provision is a collective choice. We present a model in which the members of a community, both those who fund the nonprofits and those who do not (free riders) vote, so choosing between a political program of governmental supply and a political program of non governmental supply. Afterward, they must also …

Neural Adaptations to Strength Training

2018

Scientific study of strength training has revealed numerous physiological mechanisms that contribute to: (1) acute fatigue from a single strength training session and (2) chronic adaptation to repetitive and systematic strength training. Therefore, the purpose of this chapter is initially to discuss potential neural mechanisms that influence force production from the perspective of a single repetition. Thereafter, the chapter will highlight scientific evidence for candidate neural mechanisms that acutely limit force production during a single strength training session and long-term adaptations caused by strength training. For some of these potential neural mechanisms, there is strong scient…

Marginalità, esclusione sociale e politiche di intervento. Studi e ricerche dei laboratori dei corsi di studio in servizio sociale

2022

Il volume raccoglie alcuni contributi scaturiti da attività di ricerca e didattica di due laboratori dei Corsi di studio in Servizio sociale del Dipartimento Culture e società dell’Università degli Studi di Palermo: il Laboratorio Interdisciplinare di ricerca su Corpi, Diritti, Conflitti e il Laboratorio di Servizio sociale. Marginale è chi vive una condizione di estraneità e non-appartenenza al contesto sociale, chi viene a trovarsi ai margini, ai confini del sistema sociale, a distanza dai processi centrali di distribuzione delle risorse sociali, non solo materiali, a indicare che le disuguaglianze sociali sono strettamente riconducibili a gradi diversi di integrazione sociale, e che la q…

Unilateral Maximal Isometric Hex Bar Pull Test : Within-Session Reliability and Lower Body Force Production in Male and Female Freeski Athletes

2021

The aim of the study was to (1) assess the within-session reliability of a unilateral isometric hex bar pull (UIHBP) maximal voluntary contraction (MVC) test and, (2) determine unilateral isometric absolute peak force (PFabs) and relative peak force (PF) values in freeski athletes. Twenty-one male and eight female academy to national team freeskiers performed the novel UIHBP MVC task on a force plate and PFabs and relative PF were assessed (1000 Hz). Within-session measures of PFabs offered high reliability on left and right limbs for males (ICC = 0.91–0.94, CV = 2.6–2.2%) and females (ICC = 0.94–0.94, CV = 1.4–1.6%), while relative PF measures showed good to high reliability in both left a…
