Vivere l’esperienza della “leggerezza” : uno studio qualitativo sulla percezione dell’acquagym in un gruppo di donne anziane
Literature has pointed out physical and psychological benefits of water based exercises (WBEs) for the elderly; however, few studies have investigated how old adults perceive those activities. This study was aimed at exploring the elder’s perception of WBEs, which brings the old adult to apply for an aqua-gym course and to successfully continue it. According to the aim, we opted for a Grounded Theory study, con-ducted in three swimming pools placed in the urban area of Milan (Italy) and in its suburbs. Forty women (age 72.45.8 years, meanSD) were interviewed; among them, 30 were still participating in WBEs while 10 dropped out. “Living the experience of lightness” was the emerging core category in the interviews with participants still attending the activities. This perception of lightness was associated with three main factors: discovering a lighter body during WBEs, experimenting psycho-social wellbeing and considering the instructor as unique and invaluable. Women appreciated WBEs not only because of the perception of body lightness while exercising, but also for the benefits they felt to their own mind and to mutual rela-tionships with mates. All these factors can facilitate active ageing and social inclusion. “Living the con-trast between the wish to continue the activity and the external barriers causing the drop-out” was the core category in the drop-out. In conclusion, recommendations to assist the global experience of lightness during WBEs are suggested to instructors

Analysis of heart rate and lactate concentrations during coordinative tasks : pilot study in karate kata world champions
Kata, the artistic part of karate, requires motor control, rhythm and movement differentiation capacities. When performing in a synchronised manner, kata team members have to make temporal and spatial adaptations to satisfy the requested task. It is not clear whether these coordinative adaptations modify physical output such as heart rate (HR) and blood lactate ([La−]) nor is it known how rapidly top-level athletes adapt. This study examined HR and [La−] outputs in different coordinative tasks and how accurately these tasks were done, in three world champion kata team competitors. In session 1, athletes performed their individual best trial (IM) on Gankaku, the kata that is normally executed during final team events. In sessions 2 and 3, the athletes repeated the kata with temporal and spatial variations (TV10 and TV20, SV1 and SV2). In session 4, one maximal team trial (TM) was performed. There was a decreasing trend in both HR and [La−] across the trials (HR: −2% in TV10, −4.2% in TV20, −2.9% in SV1, −3.2% in SV2; [La−]: −23.6% in TV10, −32.6% in TV20, −18% in SV1, −15.9% in SV2), and between IM and TM (HR −9.9%; [La−] − 21.5%). The coordinative tasks were achieved with a small error (<3%) in all subjects. These results indicate that top-level kata athletes easily adapt to coordinative modifications, with a reduction in HR and [La−]. Although this decline does not compromise the competition results, it also occurs when the performance is executed synchronously in a team
Il progetto “Multi-Teaching Styles Approach and Active Reflection” per l’attività motoria nella scuola primaria = The “Multi-Teaching Styles Approach and Active Reflection” Project for physical activity in the primary school
L’educazione fisica curricolare, per essere veramente sostenibile nel con-testo educativo scolastico e motorio più in generale, deve rispondere ad al-cune prerogative di adattamento ai bisogni specifici della realtà a cui essa siriferisce. In questo articolo sono sviluppate le premesse necessarie e un pos-sibile approccio da proporre per la formazione del corpo docente deputatoalla conduzione dell’attività motoria nella scuola primaria, sia esso general-ista o specialista. Sono approfonditi il concetto di sostenibilità dell’edu-cazione fisica, l’insegnamento, l’organizzazione e la conduzione dell’attivitàmotoria da parte di insegnanti per definizione preparati e padroni della ma-teria. Per questo sono considerate le strategie didattico-metodologiche dautilizzare per coinvolgere in modo adeguato gli alunni, suscitandone il nec-essario interesse per apprendere ed acquisire le competenze motorie utiliper la vita. In particolare, sono descritti il background, la metodologia ed iprincipali risultati di un primo studio condotto nell’ambito del progetto diricerca “Multi-Teaching Styles Approach and Active Reflection”.

IntroduzioneUna Educazione Fisica moderna per essere al passo con i tempi e poter assumereun ruolo culturale significativo e sostenibileall’interno della realtà scolastica deveessere capace di adattarsi per rispondere alle differenti esigenze e necessità socio-culturali di realtà scolastiche che spesso esprimono bisogni molto differenti (In-vernizzi, Dugnani, & Mauro, 2018). In alcune scuole, per esempio, diventapreminente attuare l’integrazione progressiva di più culture, favorita da globaliz-zazione e fenomeni migratori. In altre, le sfide richieste all’Educazione Fisica po-trebbero essere maggiormente rivolte ad una trasversalità disciplinare, checonsenta di esprimere un pensiero critico e riflessivo anche attraverso l’uso ditecnologie che rendono disponibili una grande quantità di informazioni, comun-que da vagliare e verificare.L’educazione della motricità non può disgiungersi quindi da una visione piùampia, che si ricolleghi alla necessità di affrontare le sfide di ogni peculiare realtàin modo flessibile e appropriato, per assumere un significato di physical literacy(Whitehead, 2010), quindi di utilità sociale, e che favorisca l’instaurarsi di “buonepratiche” come risposta di adattamento plastico alle richieste di una società sem-pre più complessa e variabile. La “normalità motoria” (proficiency barrier) costituisce comunque, in ambitoscolastico, la premessa indispensabile e la base di una autonomia funzionale perun’adeguata tutela della salute, la “qualità degli anni di vita”, un dinamismo e vi-talità psico-fisica per la gestione di sé non solo nel breve periodo, ma anche nellefasi successive della vita (Stodden, Langendorfer, & Roberton, 2009). A questo pro-posito, in questo articolo abbiamo ritenuto utile incentrare l’attenzione, più chesul quantoe sul cosafare, ampiamente studiati in letteratura, sul comefare e sullestrategie didattiche utili ad un più rapido ed efficace adattamento ai differentipossibili contesti. Il tutto trova applicazione nel progetto di ricerca “Multi-Teaching, Pietro Luigi Invernizzi, Raffaele Scurati110zione delle occorrenze di trasversalità culturale e delle caratteristiche socio-ambientali della scuola in cui si trovano ad operare.Physical education (PE) curricula, to be sustainable in the educational processand, more widely, during physical activity (PA) at school, must adapt to thespecific needs of the actual related context. This paper addresses the as-sumptions and the possible approaches for a successful teachers’ trainingfor leading physical activity in the primary school. They might be proposedto both generalists and specialists. PE sustainability, teaching processes, PAorganization and conduction from teachers expected to be competent andproficient because of their background, are also deepened. Therefore,proper teaching methods to involve the students and to promote the interestin learning and acquiring the motor competence for daily life are considered.In particular, we described the background, the procedure and the resultsof a pilot study within the “Multi-Teaching Styles Approach and Active Re-flection” research program.

Athletic performance decreases in young basketball players after sitting
The purpose of this study was to assess the effect of prolonged sitting on the vertical jump of young basketball players. After a standard warm-up of 15 minutes, players from five basketball teams underwent countermovement jump (CMJ) and stiff leg (SL) tests (T1 time point). The tests were repeated (T2 time point) after the participants spent 20 minutes under different conditions, one by each team: playing, sitting, standing, and active while sitting. Sitting players further resumed the activity for two minutes, after which the CMJ and SL tests were repeated. Neither the playing nor the standing players showed significant differences in vertical jump capacity between T1 and T2. After being seated for 20 minutes, the jump height decreased in all seated players. After workout resumption, the sitting players' jump height was only slightly lower and not significantly different than the post-warm-up condition. Sitting on the bench after warm-up decreases the performance
