‘Let Them Eat Caviar’: Alternative pathways for university students attending to ‘unfinished business’

This paper reports on a study into the educational experiences of a group of students who are accessing tertiary education through alternative entry programmes. There were three purposes for the study. The first was to identify why the students either did not finish school or go to university after school. The second was to explore the students' stated reasons for returning to university later in their lives. The third was to share the students' secondchance experiences in their first semester as university students. The study drew on theoretical ideas surrounding how students who reject school, or who have been rejected by school, may come to view education as unfinished business in their lives. Reconnection with education coincides with wider processes of individuals defining and redefining educational identities.     

Ethnicity as a moderator of the theory of planned behavior and physical activity in college students

Most college students do not meet physical activity (PA) guidelines, and ethnic disparities exist. The present study examined the utility of the theory of planned behavior (TPB) in explaining PA intentions and behavior in black and white college students and whether any TPB relationships were moderated by ethnicity. Black (n=170) and white (n=180) students completed a baseline TPB questionnaire and PA assessment 2 weeks later Hierarchical latent variable regression analyses showed that affective attitude, subjective norm, and perceived behavioral control (PBC) were significant predictors of intention for both ethnic groups, whereas the PBC-intention relationship was significantly stronger for white students. Intention significantly predicted PA for both ethnic groups. Furthermore, common and ethnic-specific beliefs were identified.     

Performance and physiological effects of different descending strategies for cross-country mountain biking

This study investigated the performance-related feasibility and physiological benefits of purposefully eliminating propulsive work while descending in mountain biking and compared values to those measured during road descending. Participants cycled uphill on a road at race pace before descending over three conditions (off-road pedalling; off-road coasting; road coasting). Relatively low power output during off-road pedalling was associated with a greater oxygen uptake (p?<?.01) when compared with off-road coasting despite no difference in vibration exposure (p?>?.05). Importantly, pedalling did not invoke a performance benefit (p?>?.05) on the descent used in this study. Significantly greater heart rate and oxygen uptake (both p?<?.01) were observed between road and off-road descending, likely caused by the increase in terrain-induced vibrations (p?<?.01) experienced between the bicycle and rider. Results indicate that reducing propulsive work during descending can improve recovery without being disadvantageous to performance. Similarly, the vibrations experienced during road descending are relatively low, and further reduce oxygen cost. In an effort to increase efficiency, it is recommended that mountain bike athletes focus on skills to increase descending speed without the addition of pedalling, and that equipment be used to decrease vibrations nearer to those seen on the road.     

Normobaric hypoxia increases the growth hormone response to maximal resistance exercise in trained men

This study examined the effect of hypoxia on growth hormone (GH) release during an acute bout of high-intensity, low-volume resistance exercise. Using a single-blinded, randomised crossover design, 16 resistance-trained males completed two resistance exercise sessions in normobaric hypoxia (HYP; inspiratory oxygen fraction, (FiO₂) 0.12, arterial oxygen saturation (SpO₂) 82?±?2%) and normoxia (NOR; FiO₂ 0.21, SpO₂ 98?±?0%). Each session consisted of five sets of three repetitions of 45° leg press and bench press at 85% of one repetition maximum. Heart rate, SpO₂, and electromyographic activity (EMG) of the vastus lateralis muscle were measured throughout the protocol. Serum lactate and GH levels were determined pre-exposure, and at 5, 15, 30 and 60?min post-exercise. Differences in mean and integrated EMG between HYP and NOR treatments were unclear. However, there was an important increase in the peak levels and area under the curve of both lactate (HYP 5.8?±?1.8 v NOR 3.9?±?1.1?mmol.L^?1 and HYP 138.7?±?33.1 v NOR 105.8?±?20.8?min.mmol.L^?1) and GH (HYP 4.4?±?3.1 v NOR 2.1?±?2.5?ng.mL^?1 and HYP 117.7?±?86.9 v NOR 72.9?±?85.3?min.ng.mL^?1) in response to HYP. These results suggest that performing high-intensity resistance exercise in a hypoxic environment may provide a beneficial endocrine response without compromising the neuromuscular activation required for maximal strength development.     

Discovering frequently recurring movement sequences in team-sport athlete spatiotemporal data

Athlete external load is typically analysed from predetermined movement thresholds. The combination of movement sequences and differences in these movements between playing positions is also currently unknown. This study developed a method to discover the frequently recurring movement sequences across playing position during matches. The external load of 12 international female netball athletes was collected by a local positioning system during four national-level matches. Velocity, acceleration and angular velocity were calculated from positional (X, Y) data, clustered via one-dimensional k-means and assigned a unique alphabetic label. Combinations of velocity, acceleration and angular velocity movement were compared using the Levenshtein distance and similarities computed by the longest common substring problem. The contribution of each movement sequence, according to playing position and relative to the wider data set, was then calculated via the Minkowski distance. A total of 10 frequently recurring combinations of movement were discovered, regardless of playing position. Only the wing attack, goal attack and goal defence playing positions are closely related. We developed a technique to discover the movement sequences, according to playing position, performed by elite netballers. This methodology can be extended to discover the frequently recurring movements within other team sports and across levels of competition.     

The brain and fatigue: new opportunities for nutritional interventions?

It is clear that the cause of fatigue is complex, influenced by events occurring in both the periphery and the central nervous system. Work conducted over the last 20 years has focused on the role of brain serotonin and catecholamines in the development of fatigue, and the possibility that manipulation of neurotransmitter precursors may delay the onset of fatigue. While there is some evidence that branched-chain amino acid and tyrosine ingestion can influence perceived exertion and some measures of mental performance, the results of several apparently well-controlled laboratory studies have not demonstrated a positive effect on exercise capacity or performance under temperate conditions. As football is highly reliant upon the successful execution of motor skills and tactics, the possibility that amino acid ingestion may help to attenuate a loss in cognitive function during the later stages of a game would be desirable, even in the absence of no apparent benefit to physical performance. There are several reports of enhanced performance of high-intensity intermittent exercise with carbohydrate ingestion, but at present it is difficult to separate the peripheral effects from any potential impact on the central nervous system. The possibility that changes in central neurotransmission play a role in the aetiology of fatigue when exercise is performed in high ambient temperatures has recently been examined, although the significance of this in relation to the pattern of activity associated with football has yet to be determined.     

Supervising a social science undergraduate dissertation: staff experiences and perceptions

This article reports on a research project that investigated the experiences and perceptions of staff supervising final year social science undergraduates enrolled on a dissertation module in a post-1992 UK university. Using data from semi-structured interviews, the article explores staffs perspectives of the supervision process, the different approaches taken by staff to supervision and the challenges they face in supporting students through the dissertation journey. The paper offers a picture of the dissertation supervisors’ experiences and, it is hoped, will encourage other supervisors to interrogate their own supervision in light of the practice of colleagues.     

Specific reading difficulties in Chinese, English, or both: longitudinal markers of phonological awareness, morphological awareness, and RAN in Hong Kong Chinese children

What are the longitudinal cognitive profiles of Hong Kong Chinese children with specific reading difficulties in Chinese only, in English only, or both? A total of 16 poor readers each of Chinese (PC) and English (PE) and 8 poor readers of both orthographies (PB) were compared to a control sample (C) of 16 children; all were drawn from a statistically representative sample of 154 Hong Kong Chinese children tested at ages 5 to 9 years. PE and PB children's mothers had lower education levels than did the other groups. With children's ages and mothers' education levels statistically controlled, the PE, PC, and PB groups were significantly lower than the C group on phonological awareness. The PB and PE groups also scored significantly lower than the others on English vocabulary across years, whereas the PC and PB groups were significantly poorer than the C and PE groups on morphological awareness across years. Finally, the PB group was significantly slower than the other groups on speed naming at every age tested, underscoring the potential importance of automaticity in reading across orthographies. Findings highlight the need to consider the issue of how to identify reading difficulties in a second language.
