Carbohydrates for training and competition

An athlete's carbohydrate intake can be judged by whether total daily intake and the timing of consumption in relation to exercise maintain adequate carbohydrate substrate for the muscle and central nervous system ("high carbohydrate availability") or whether carbohydrate fuel sources are limiting for the daily exercise programme ("low carbohydrate availability"). Carbohydrate availability is increased by consuming carbohydrate in the hours or days prior to the session, intake during exercise, and refuelling during recovery between sessions. This is important for the competition setting or for high-intensity training where optimal performance is desired. Carbohydrate intake during exercise should be scaled according to the characteristics of the event. During sustained high-intensity sports lasting ~1 h, small amounts of carbohydrate, including even mouth-rinsing, enhance performance via central nervous system effects. While 30-60 g · h(-1) is an appropriate target for sports of longer duration, events >2.5 h may benefit from higher intakes of up to 90 g · h(-1). Products containing special blends of different carbohydrates may maximize absorption of carbohydrate at such high rates. In real life, athletes undertake training sessions with varying carbohydrate availability. Whether implementing additional "train-low" strategies to increase the training adaptation leads to enhanced performance in well-trained individuals is unclear.     

What Motivates Today’s Criminal Justice Student to Become an Engaged Learner?

The use of student-centered High Impact Practices (HIPs) has become increasingly popular across university and college faculty. HIPs increase student development of critical thinking, problem solving, and communication skills. HIPs also provide students the opportunity to engage in real-world application of course knowledge. While HIPs increase student engagement and intrinsic motivation, little research has explored student perception of these concepts. This article describes a pilot course offered to upper level criminal justice students that incorporated three HIPs: undergraduate research, collaborative assignments, and service/community-based learning. Semi-structured interviews were used to facilitate individual student discussion regarding their perceptions and experiences of the course related to their level of motivation and engagement as compared to traditional classes. Results indicated student expectations for the course were exceeded; students believed the course would positively impact their future career/education plans; and the HIPs motivated the students to engage more than their traditional lecture-oriented courses.     

‘I was kind of teaching myself’: teachers’ conversations about social justice and teaching for change

This article shares teachers’ conversations within teacher inquiry groups and considers how this reflective approach has potential for transforming teachers’ practices. Conversations took place at the early stages of a longer teacher inquiry project and centred on the critical interrogation of social justice-oriented children’s literature. These conversations served as a forum to help teacher professional learning communities and to reconcile understandings about social justice, action and agency within larger political and cultural forums of teaching. The teacher inquiry sessions shared in this paper explore teachers’ beginning struggles with conceptualizations of social justice, and the teacher’s role in imparting values to students. Teacher participants imparted their experience and practice as they negotiated their own understanding and implementation of social justice education in their schools. The teacher inquiry groups provided a needed supportive space where classroom teachers’ struggles were shared alongside their beliefs and pedagogical approaches so that a social justice agenda could be achieved.     

Re-imagining the local in national cultural policy formulation – the case of the Anglophone Caribbean

ABSTRACT

The formulation of cultural policies in the Anglophone Caribbean constantly straddles the demands of global, regional and national imperatives as a function of its position as a region of post-colonial, small-island states. This paper will argue that the role these factors play in the art of policy making problematises conventions in the current global/local (glocal) debate circulating in the arena of Cultural Policy Studies. The paper shows that cultural policy making in the Caribbean constitutes a mélange of approaches that are in a constant state of contestation during the policy-making process. It employs content analysis of cultural policy texts from selected Caribbean states, as well as an analysis of stakeholder views from the national cultural policy consultations in Trinidad and Tobago to derive its findings. A Five Factor framework was developed to illustrate the range of responses that guide and shape local actors and activities in the national cultural policy domain. The research concludes that the relationship between the national and local (nocal) actors has to be re-imagined if cultural policy is to deliver on its promise of social transformation in the Caribbean.     

Why do bad balls get wickets? The role of congruent and incongruent information in anticipation

Skilled anticipation is underpinned by the use of kinematic and contextual information. However, few researchers have examined what happens when contextual information suggests an outcome that is different from the event that follows. We aimed to bridge this gap by manipulating the relationship between contextual information and final ball location in a cricket-batting task. We predicted that when contextual information is congruent with the eventual outcome then anticipation would be facilitated. In contrast, when contextual information is incongruent, this would lead to a confirmation bias on kinematic information and result in decreased anticipation accuracy. We expected this effect to be larger in skilled performers who are more able to utilise context. Skilled and less-skilled cricket batters anticipated deliveries presented using a temporally occluded video-based task. We created conditions whereby contextual information and event outcome were either congruent or incongruent. There was a significant skill by condition interaction (p < 0.05). The skilled group anticipated significantly more accurately than the less-skilled group on the congruent trials. Both groups anticipated less accurately on incongruent trials, with the skilled participants being more negatively affected. Skilled performers prioritise contextual information and confirmation bias affects the use of kinematic information available later in the action.
