Research on Service-Learning in Physical Activity and Sport: Where We Have Been, Where We Are, Where We Are Going
2022
Higher education is under constant transformation through the use of new pedagogical models such as university service-learning (SL). Indeed, there has been an exponential uptake of university SL, among others, in the field of physical activity and sport (PAS) along with research examining these practices. However, these initiatives highlight the need to improve the quality of research in this field. This paper presents a systematic review focused on how research in this arena has been carried out, examining the following topics: paradigm, methods, instruments, discipline, limitations, and further research. A total of 45 articles met the inclusion criteria. The results show that qualitative…
Resistance Training Induces Antiatherogenic Effects on Metabolomic Pathways
2019
Introduction: Arising evidence suggests that resistance training has the potential to induce beneficial modulation of biomarker profile. To date, however, only immediate responses to resistance training have been investigated using high-throughput metabolomics whereas the effects of chronic resistance training on biomarker profile have not been studied in detail. Methods: A total of 86 recreationally active healthy men without previous systematic resistance training background were allocated into i) a resistance training (RT) group (n=68, age 33 ± 7 years, body mass index (BMI) 28 ± 3 kg/m2 ) and ii) a non-RT group (n=18, age 31 ± 4 years, BMI 27 ± 3 kg/m2 ). Blood samples were collected at…
Big vs powerful : molecular signalling responses to hypertrophic and power resistance exercise modalities
2015
Introduction: The effects of resistance exercise (RE) loading on molecular signalling proteins, including those involved in protein translation and thus skeletal muscle hypertrophy have been extensively studied. However, there is little research on high power RE loading and molecular signalling proteins, and also on possible relationships between signalling proteins and recovery from RE loading. Methods: 7 young men (31±6 years, 178.9±4cms, 84.6±5 kgs) performed 1 hypertrophy loading session (HYP) (5x10 80% 1RM leg presses (LP)) and 1 power loading session (POW) (10x5 70% 1RM LP), with each session separated by 7 days, in a crossover design, prior and subsequent to 12 weeks of resistance tr…
Physiological and Molecular Adaptations to Strength Training
2019
High muscle contraction forces that lead to gains in muscle function, size, and strength characterize resistance exercise training. The purpose of this chapter is to outline the adaptations in myofiber size and metabolism that occur by stimuli of hormones and local growth factors, mechanical and metabolic stress of muscle tissue, and myofibrillar disruptions induced by a resistance exercise bout. The chapter will highlight the network of intracellular pathways (including mTOR signaling) that ultimately lead to increases in gene expression and protein synthesis. Accumulation of acute exercise responses by systematic training over time modulate the muscle proteome that can be observed as chan…
Predicting the 2000‐m Rowing Ergometer Performance from Anthropometric, Maximal Oxygen Uptake and 60‐s Mean Power Variables in National Level Young R…
2020
Abstract Many studies reported various relationships between 2000-m rowing performance and anthropometric as well as metabolic variables, however, little is known about 60-s mean power in elite youth athletes. The aim of this study was to develop different regression models to predict 2000-m rowing indoor performance time (t2000) using anthropometric variables, maximal oxygen uptake (VO2max) and mean power established during a 60-s all-out test (W60) in national elite youth rowers. Fifteen youth male Italian rowers (age: 15.7 ± 2.0 years; body height: 176.0 ± 8.0 cm; body mass: 71.2 ± 10.0 kg) performed an incremental maximal test, a 60-s all-out test and a 2000-m race simulation using a Co…
MicroRNAs in Extracellular Vesicles in Sweat Change in Response to Endurance Exercise
2020
Background: To date, microRNAs (miRs) carried in extracellular vesicles (EVs) in response to exercise have been studied in blood but not in non-invasively collectable body fluids. In the present study, we examined whether six exercise–responsive miRs, miRs-21, -26, -126, -146, -221, and -222, respond to acute endurance exercise stimuli of different intensities in sweat. Methods: We investigated the response of miRs isolated from sweat and serum EVs to three endurance exercise protocols: (1) maximal aerobic capacity (VO2max), (2) anaerobic threshold (AnaT), and (3) aerobic threshold (AerT) tests. Sauna bathing was used as a control test to induce sweating through increased body temperature i…
Tensions and Paradoxes of Scaling Up : A Critical Reflection on Physical Activity Promotion
2022
Background: Achieving system-level, sustainable ‘scale-up’ of interventions is the epitome of successful translation of evidence-based approaches in population health. In physical activity promotion, few evidence-based interventions reach implementation at scale or become embedded within systems for sustainable health impact. This is despite the vast published literature describing efficacy studies of small-scale physical activity interventions. Research into physical activity scale-up (through case-study analysis; evaluations of scale-up processes in implementation trials; and mapping the processes, strategies, and principles for scale-up) has identified barriers and facilitato…
THE ROLE OF PHYSICAL ACTIVITY IN MANAGEMENT OF BODY WEIGHT IN PSYCHOTIC SUBJECTS
2013
Psychotic subjects live an unhealthy lifestyle that tends to reinforce the metabolic syndrome (1). It is known, indeed, that antipsychotic treatments stimulate appetite (2) and induce weight gain (3). Several therapeutic approaches including psycho-educational behavioral interventions and exercise training programs have been elaborated in order to manage antipsychotic-induced weight gain (4,5). Wirshing et al. (2006) elaborated a specific project based on oral presentations in order to educate psychotic subjects about lifestyle changes they can adopt to reduce weight gain. They showed that patients with mental illness are able to benefit from educational presentations about nutrition and a …
Esercizi di traduzione in London, British Library, Harley 1002
2017
London, British Library, Harley 1002 è un codice miscellaneo il cui contenuto è descritto da David Thomson . Il manoscritto comprende, tra l’altro, ai ff. 31-81, un trattato di ortografia disposto in ordine alfabetico: nello spazio bianco rimasto tra le lettere R e S del testo sono stati copiati cinque gruppi di versi in inglese, seguiti dalla rispettiva versione in latino (ff. 72r-72v) . I versi appartengono a una categoria di strumenti didattici altrimenti documentata nei codici inglesi del XIV e XV sec., ma che, almeno nel caso dei primi due esercizi, è interpretata con libertà e messa in atto con una certa capacità. Sia il primo componimento, ‘Today in the dawnyng I hyrde þo fowles syng…
"Write in English on your notebook" : analysis of creative writing exercises in a Finnish EFL workbook
2016
Vaikka luovalla kirjoittamisella on tutkittu olevan paljon etuja vieraan ja toisen kielen oppimisessa, Perusopetuksen opetussuunnitelman perusteet (2004) ei tarjoa täsmällisiä ohjeita luovan kirjoittamisen opetukseen englannin kielen oppiaineessa. Täten luovan kirjoittamisen tehtävien suunnittelu on opettajien ja oppimateriaalien valmistajien vastuulla. Oppikirjat ovat edelleen hyvin laajasti käytettyjä oppimateriaaleja, joten niiden tutkiminen tarjoaa tietoa myös opetuksesta yleensä. Tutkielman päämääränä on selvittää luovan kirjoittamisen tehtävien esiintymistä yhdessä suomalaisessa englannin kielen tehtäväkirjassa. Tätä tutkittiin kahden tutkimuskysymyksen avulla, joista ensimmäinen kosk…
