Visual error amplification showed no benefit for non-naïve subjects in trunk-arm rowing
Full text linkMotor learning is assumed to be a partly error driven process. Motor learning studies on simple movements have shown that skilled subjects benefit from training with error amplification. Findings of studies with simple movements do not necessarily transfer to complex sport movements. The goal of this work was to determine the benefit of visual error amplification for non-naïve subjects in learning a fast rowing movement.We conducted a study comparing non-naïve subjects receiving a fading, visual feedback with visual error amplification against a control group receiving the same visual feedback without error amplification. Separate outcome metrics were applied for the domains of spatial and velocity magnitude errors. Besides error metrics, variability metrics were evaluated for both domains, such that they could be interpreted in quantitative relation to each other.The implemented error amplification did not cause group differences in any variable. Subjects with or without error amplification reached similar absolute levels in error and variability. Possible reasons remain speculative. For implementing error amplification to the training of complex movements design decisions must be made for which an informative basis is missing, e.g. the error amplification gains

Full text linkValidity of the Actiheart step test for the estimation of maximum oxygen consumption in endurance athletes and healthy controls
Full text linkSubmaximal step tests are often used for estimation of maximum oxygen consumption (VO2max) in humans. The validity of the Actiheart step test for VO2max estimation was not fully studied yet. Therefore, purpose of the study was to estimate VO2max using the Actiheart step test and to compare the data with measured VO2max in endurance trained athletes (ATH) and healthy non-athletes (CON).68 ATH (54% men, 28.0±5.4 yrs, 20.9±1.7 kg∙m-2) and 63 CON (46% men, 27.6±5.1 yrs, 22.1±1.7 kg∙m-2) performed the Actiheart step test and a spiroergometry for assessment of VO2max. In addition, resting metabolic rate (RMR; indirect calorimetry), maximum heart rate (HRmax; heart rate monitoring system during spiroergometry), and sleeping heart rate (SHR; Actiheart 6-day long term measurement) were determined. Validity of two different Actiheart software entry modes was assessed: (1) AHraw (estimated RMR [Schofield] and HRmax [Tanaka], SHR = 70 bpm) and (2) AHcomplete (measured RMR, HRmax, and SHR). Validity was investigated using linear regression (R2 and standard error of the estimate (SEE)) and repeated-measures ANOVA with a Bonferroni post-hoc correction. The level of significance was set to α=0.05.VO2max estimated by AHraw was significant related to measured VO2max in women CON (R2=0.22; p<0.05), whereas when VO2max was estimated by AHcomplete the relation was significant in women ATH and CON, and in men CON (R2=0.17-0.24; p<0.05). AHraw significantly underestimated VO2max in the total sample by 8% (51.4±10.2 vs. 55.9±7.6 ml∙kg-1∙min-1; p<0.0001), whereas no significant difference between AHcomplete and the criterion method was found (57.0±11.1 vs. 55.9±7.6 ml∙kg-1∙min-1; p=0.26).The Actiheart step test is an acceptable tool for the estimation of VO2max if an error within 8% can be tolerated. However, accuracy of the VO2max prediction is much improved when entering measured variables, such as RMR, SHR, and HRmax, into the software
Le macchiette interculturali di Renato Carosone
Full text linkThe article wants to demonstrate that some of Renato Carosone’s most successful songs, written together with Nicola Salerno in the 1950s (in particular “Tu vuò fa’ l’americano”, “Torero”, “Caravan petrol” and “‘O pellirossa”), are tightly inspired by the ironic and satirical portraits of the 'macchietta napoletana’. Focusing on protagonists who attempt to imitate the behaviors or fashions of other cultures, the analyzed songs reveal an intercultural approach, based on a conception of cultures as distinct or even competing spheres. This attitude is very clear especially at the level of lyrics, also because the proclaimed opinions follow from the point of view of the ‘people’, whereas the music and, even more, the theatrical performances of Carosone’s formations sometimes create a more complex subtlety which can measure up to transculturality, as in the case of “Tu vuò fa’ l’americano”
Monitoring body temperature during moderate intensity exercise and inactive recovery in the cold: a pilot study
Full text linkExposure to cold ambient conditions during outdoor recreation can lead to significant heat loss. It is unknown how fast body temperature decreases or how fast a person could become hypothermic in cold temperatures. We present a series of pilot tests involving moderate intensity exercise and inactive recovery in the cold to monitor how body temperature changes with exposure to -10°C. The primary aim of this pilot study was to test the feasibility of the proposed protocol with the intention to design a main study. The primary questions were: (i) to what degree does body temperature increase or decrease with this protocol, (ii) whether epitympanic temperature is a suitable measure of core temperature using a recently developed, non-invasive device and (iii) if participants are able to tolerate the cold during inactive recovery. This pilot series included seven participants. After an acclimatization phase (15 minutes), participants exercised at 60% peak heart rate (20 minutes) followed by a seated, inactive recovery phase (15 minutes) in the cold. The mean ambient conditions were -10.0±0.4°C and 66.1±8.6% relative humidity and no wind. The primary findings based on the feasibility criteria were that body temperature increased while exercising at an intensity of 60% HRpeak and decreased during inactive recovery by -0.3±0.1°C (epitympanic temperature). Secondly, the agreement between epitympanic and esophageal temperature (mean difference 0.2°C, 95% confidence interval -0.5 to 0.0, p=0.095) was better than in previous studies. Finally, all participants were able to tolerate the cold and complete the study despite thermal discomfort and shivering in the recovery phase. This protocol was successful in showing small changes in body temperature during exercise and recovery in the cold, though some modifications to the current protocol are recommended to elicit a larger effect size
Joseph Baker & Nick Wattie – new insights into the concept of innate talent in sport
Full text linkIn this target article, Joseph Baker and Nick Wattie revisited the review article on the evidence for innate talent published by Howe, Davidson and Sloboda 20 years ago, and focused mainly on whether this concept was reasonable and scientifically sound, and whether the concept of innate talent was valid also in the world of sport. The main article (CISS_3:006) is then discussed by five peer commentaries (CISS_4:102 – CISS_4:106), written by research experts in this field. Finally, Joseph Baker and Nick Wattie provided a closing response (CISS_4:108) acknowledging critiques, suggestions, and extensions brought forward by the commentators
From the crowdfunding of sport to shared sponsorship
No full textThe rise of crowdfunding as a way of funding sport projects has prompted numerous companies to become involved in these campaigns. This paper explores a model of crowdfunding in which a sponsor company supports individual projects. A qualitative study based on interviews with crowdfunding executives showed that campaigns are more likely to be successful if they include a sponsor company, and that crowdfunding platforms and the projects they support have become a new interactive, online communication tool for sponsors. Our data revealed four modes of corporate involvement in crowdfunding and fourteen objectives companies hope to achieve through this involvement. Three of these objectives can be attained exclusively via this communication tool. In addition, companies focus on five “success factors” when deciding whether or not to sponsor a crowdfunding campaign. This model of corporate-supported crowdfunding is creating a new paradigm of “shared” (by a community) sponsorship that will complement the current system of “confined” (to specific companies) sponsorship
“’O sole mio” e l’habanera: napoletanità e cosmopolitismo nella prima era della popular music
Full text link“’O sole mio” is considered the quintessential Neapolitan song, a widely popular musicalicon of ‘Neapolitanness’. And yet, the song also raises questions about the nature of‘Neapolitanness’ in music, as it is based on a habanera pattern, a rhythm originated inCuba which became very popular in Europe in the late XIX century. The article reflectson how music could sound ‘Neapolitan’ (and thus ‘Italian’), and how these features areestablished, observing the case of “’O sole mio” from a cultural historical perspective
