Sleep restriction and degraded reaction-time performance in Figaro solo sailing races

Abstract

In solo offshore sailing races like those of the Solitaire du Figaro, sleep must be obtained in multiple short bouts to maintain competitive performance and safety. Little is known about the amount of sleep restriction experienced at sea and the effects that fatigue from sleep loss have on sailors’ performance. Therefore, we assessed sleep in sailors of yachts in the Figaro 2 Beneteau class during races and compared response times on a serial simple reaction-time test before and after races. Twelve men (professional sailors) recorded their sleep and measured their response times during one of the three single-handed races of 150, 300 and 350 nautical miles (nominally 24–50 h in duration). Total estimated sleep duration at sea indicated considerable sleep insufficiency. Response times were slower after races than before. The results suggest that professional sailors incur severe sleep loss and demonstrate marked performance impairment when competing in one- to two-day solo sailing races. Competitive performance could be improved by actively managing sleep during solo offshore sailing races.     

小提琴独奏曲《阳光照耀着塔什库尔干》演奏指法与弓法技术探析

小提琴独奏曲《阳光照耀着塔什库尔干》采用了新疆塔吉克族的音乐素材、特性的增二度音程、装饰性半音进行并吸收模仿了新疆民间乐器冬不拉的弹奏手法,突出了其创作的风格特点。经实验：应用减少滑指、八度双音上下行皆用一四指的指法和减少连续下弓的弓法,才能使演奏充分地表现该曲的风格特点。

You are never alone: understanding the educational potential of an ‘urban solo’ in promoting place-responsiveness

Abstract

Solos have a long history in outdoor learning (education) for their use in ‘wilderness’ settings. They have been theorised in experiential education literature and through phenomenological concepts where dwelling and solitude provide unstructured time for individual reflection. Place-Based Education provides opportunities for educators to develop place-responsive practices in areas local to where people live, work and study. This paper reports on an exploratory investigation into a Masters-level course. Students were required to undertake an ‘urban solo’ in a familiar place and consider how ontological disruption might be nurtured in city-based locations. Six students participated in semi-structured interviews which were then analysed thematically using a constructivist grounded theory approach. Findings revealed that their solo experiences had had a profound and unexpected effect on all students. These changes seemed to occur as the result of an ontological shift in the students from being passive receptors of stimuli to engaging more actively with their surroundings. We concluded that, because of its simplicity and close proximity to school grounds, the urban solo is one way for teachers to overcome the barriers they consistently report to outdoor learning. We recommend that future studies draw further on urban theorists to develop more city-based, place-responsive practices.
