Animating grandma : the indices of age and agency in contemporary children

Analysis of three animated children's films, each with heroic grandmothers motivating their plotlines, suggests a shift in the representational politics mediating older women to child audiences. The films function as critiques, reflections, and mechanisms of contemporary capitalism's available sociocultural locations for older women, modelled through varying degrees of subversive performance. Interrogating the agency potential of housework, nurture and extreme sports, this article assesses the role and function of the “Granny trope” in contemporary children's media.

Extreme surfing : personal and psychological aspects of big wave riders

This qualitative study investigated personal and psychological aspects of big wave riders. A cross-sectional design with non probability purposive sampling was used to gain personal interviews with 32 elite surfers who regularly ride big, life threatening waves. Each athlete was asked three open questions: 1. What do you think are the most important qualities and attributes a surfer needs for riding big waves? 2. What type of mindset is best for riding big waves?, and 3.What motivates you to ride big waves? Content analysis of the taped interview transcripts revealed seven key qualities and attributes including having a thrill seeking, confident and goal oriented personality, a high level of mental strength and control, and an intimate relationship with the ocean. The best mindset included an individually defined arousal level, a committed attitude, and a simple, yet highly aware, focus. Motivations were primarily intrinsic, though drives indicative of a behavioral addiction to the act of riding big waves also emerged. Evidence of common developmental stages for riding big waves also arose from the interviews. Optimal mental approach and preparation techniques are discussed that will enable big wave riders, and other extreme athletes, to more safely and successfully manage extreme situations.

Post-exercise muscle glycogen repletion in the extreme : effect of food absence and active recovery

Glycogen plays a major role in supporting the energy demands of skeletal muscles during high intensity exercise. Despite its importance, the amount of glycogen stored in skeletal muscles is so small that a large fraction of it can be depleted in response to a single bout of high intensity exercise. For this reason, it is generally recommended to ingest food after exercise to replenish rapidly muscle glycogen stores, otherwise one's ability to engage in high intensity activity might be compromised. But what if food is not available? It is now well established that, even in the absence of food intake, skeletal muscles have the capacity to replenish some of their glycogen at the expense of endogenous carbon sources such as lactate. This is facilitated, in part, by the transient dephosphorylation-mediated activation of glycogen synthase and inhibition of glycogen phosphorylase. There is also evidence that muscle glycogen synthesis occurs even under conditions conducive to an increased oxidation of lactate post-exercise, such as during active recovery from high intensity exercise. Indeed, although during active recovery glycogen resynthesis is impaired in skeletal muscle as a whole because of increased lactate oxidation, muscle glycogen stores are replenished in Type IIa and IIb fibers while being broken down in Type I fibers of active muscles. This unique ability of Type II fibers to replenish their glycogen stores during exercise should not come as a surprise given the advantages in maintaining adequate muscle glycogen stores in those fibers that play a major role in fight or flight responses.
