The sit up test to exhaustion as a test for muscular endurance evaluation
2015
Aims/Hypothesis The aim of this study was to examine the sit up test to exhaustion as a field test for muscular endurance evaluation in a sample of sedentary people of both sexes. Methods A cross-sectional study was performed. Three-hundred-eighty-one participants volunteered for the study (28.5 ± 10.0 years; 168.2 ± 8.9 cm; 65.1 ± 11.1 kg), of which 194 males (27.5 ± 10.2 years; 173.6 ± 7.0 cm; 71.2 ± 5.2 kg) and 187 females (29.6 ± 10.1 years; 162.6 ± 7.1 cm; 58.7 ± 8.9 kg). Each subject voluntarily and randomly performed: a sit up test (SUT), a push up test (PUT), and a free weight squat test (ST), all till exhaustion. A multiple regression analysis was adopted for data analysis. Subsequ…
Keep Your Piece of Cake, We’ll Squat the Bakery! Autonomy Meets Repression and Institutionalisation
2017
Squatting is usually subject to institutionalisation, co-optation and repression. Legalisation of the squats is also a controversial issue among activists. This chapter provides an overview of these topics in Central-Northern European cities (Berlin, Copenhagen and Paris) and Southern European cities (Madrid, Barcelona and Rome). The authors explore how local authorities respond to squatting in different protest cycles and the consequences of those responses. Resistance to negotiations and legalisation are eventually considered within the framework of the anti-capitalist orientation of most squatters’ movements. Furthermore, the authors’ comparison across cities takes into account local con…
Validation of a subject specific 3-actuator torque-driven model in human vertical jumping.
2013
In this study, a forward dynamic subject specific 3-actuator torque-driven model of the human musculoskeletal system was created based on measurements of individual characteristics of a subject. Simulation results were compared with experimental vertical squat jumping with and without adding weights. By analyzing kinematic and kinetic experimental data at the instant of the toe-off for the same initial conditions, it was shown that a simple computer simulation using a suitable cost function could reproduce the real task performed by humans. This investigation is the first step in a wider project that will incorporate elastic components, and that will evaluate the advantages of the individua…
Effect of the MobilityWOD training program on functional movement patterns related to the risk of injury in CrossFit practitioners
2020
Background: CrossFit is an increasingly popular form of physical activity. However, due to its specificity and high intensity, it carries with it a considerable risk of injuries. So it is important to know if some specific training including exercises derived from physiotherapy and functional training (MobilityWOD) can reduce the risk of injury. Objective: The aim of the study is to assess the effect of MobilityWOD training program on functional movement patterns related to the risk of injury in adult male CrossFit practitioners. Methods: The study included 30 men aged 20-35 years old who practice CrossFit training five timeper week. Initially, a functional evaluation was performed using th…
Occupations of Housing and Social Centers in Rome: A Durable Resistance to Neoliberalism and Institutionalization
2017
Squatting for housing and social centers has a long tradition in Rome since the end of the 1960s. By the mid-1970s, the occupation of buildings to set up political and social activities became part of the repertoire of left radical movements. In this chapter a set of 34 squatted spaces for housing and social centers in Rome active in 2014 is analysed. Squatting practices thus provide a lens to interpret the evolution of urban struggles, urban development and the changing sociopolitical contexts. Furthermore, Mudu and Rossini examine the role played by the processes of neutralization, co-optation, normalization and contention that explain the institutionalization of squatting in the city of …
Teorie globali per azioni locali: i processi autonomi di riappropriazione dello spazio
2014
Le pratiche autonome di (ri)appropriazione e riconversione temporanea a fini “pubblici” di aree in disuso hanno fatto emergere nelle principali città europee (e non solo) e in maniera significativa in alcune tra le più importanti città italiane, esperienze di partecipazione interessanti dal punto di vista della sperimentazione di pratiche capaci di proporre politiche pubbliche dal basso e di costruire strategie alternative di “produzione dello spazio” (Lefebvre, 1991). Per poter costruire queste “utopie concrete” è come se i poveri, gli sfruttati, “coloro che non ci stanno”, ricorrendo a forme di disobbedienza radicale, definissero uno “stato d’eccezione proclamato dal basso” (Virno, 2012),…
Two-Leg Squat Jumps in Water: An Effective Alternative to Dry Land Jumps
2009
The current study was designed to quantify and compare the kinetic parameters of two-leg squat jumps carried out on dry land, in water and in water using area devices that increase drag force. Twelve junior female handball players who had been competing at national level for the previous two years volunteered to participate in the study. Intensity of the two-leg squat jump was examined using a force plate (9 253-B11, Kistler Instrument AG, Winterthur, Switzerland) in three different conditions: on dry land, in water and in water using devices. An ANOVA with repeated measurements (condition) was applied to establish differences between the three jumps. The results show that peak impact force…
HemoKinect: A Microsoft Kinect V2 Based Exergaming Software to Supervise Physical Exercise of Patients with Hemophilia
2018
Patients with hemophilia need to strictly follow exercise routines to minimize their risk of suffering bleeding in joints, known as hemarthrosis. This paper introduces and validates a new exergaming software tool called HemoKinect that intends to keep track of exercises using Microsoft Kinect V2&rsquo
Acute Effects of Loaded Half-Squat Jumps on Sprint Running Speed in Track and Field Athletes and Soccer Players
2016
The purpose of the study was to determine the acute responses to a jump squat protocol designed to induce postactivation potentiation on sprint running performance in experienced track and field athletes and soccer players. Twenty-five regional level athletes (12 track and field: ∼17 years; ∼177 cm; ∼73 kg and 13 soccer: ∼18 years; ∼175 cm; ∼72 kg) performed 2 test sessions assessing 40-m sprint running performance in a balanced, crossover design. Dual-beam light timing gates measured 0-20 and 20-40 m sprint times before and after either 9 minutes of sitting (control) or 2 sets of 6 repetition half-squat jump with the load eliciting maximum power (experimental) conditions. Sprint performanc…
When the seasons don't fit: Speedy molt as a routine carry-over cost of reproduction
2013
The failure of animals to fit all life-cycle stages into an annual cycle could reduce the chances of successful breeding. In some cases, non-optimal strategies will be adopted in order to maintain the life-cycle within the scope of one year. We studied trade-offs made by a High Arctic migrant shorebird, the red knot Calidris canutus islandica, between reproduction and wing feather molt carried out in the non-breeding period in the Dutch Wadden Sea. We compared primary molt duration between birds undertaking the full migratory and breeding schedule with birds that forego breeding because they are young or are maintained in captivity. Molt duration was ca. 71 days in breeding adults, which wa…
