The effect of wave conditions and surfer ability on performance and the physiological response of recreational surfers.

This study investigated the effects of wave conditions on performance and the physiological responses of surfers. After institutional ethical approval 39 recreational surfers participated in 60 surfing sessions where performance and physiological response were measured using global positioning system (GPS) heart rate monitors. Using GPS, the percentage time spent in surfing activity categories was on average 41.6, 47.0, 8.1, and 3.1% for waiting, paddling, riding, and miscellaneous activities, respectively. Ability level of the surfers, wave size, and wave period are significantly associated with the physiological, ride, and performance parameters during surfing. As the ability level of the surfers increases there is a reduction in the relative exercise intensity (e.g., average heart rate as a percentage of laboratory maximum, rpartial = -0.412, p < 0.01) which is in contrast to increases in performance parameters (e.g., maximum ride speed (0.454, p < 0.01). As the wave size increased there were reductions in physiological demand (e.g., total energy expenditure rpartial = -0.351, p ≤ 0.05) but increases in ride speed and distance measures (e.g., the maximum ride speed, 0.454, p < 0.01). As the wave period increased there were increases in intensity (e.g., average heart rate as a percentage of laboratory maximum, rp = 0.490, p < 0.01) and increases in ride speed and distance measures (e.g., the maximum ride speed, rpartial = 0.371, p < 0.01). This original study is the first to show that wave parameters and surfer ability are significantly associated with the physiological response and performance characteristics of surfing.

Anthropometric variables and their relationship to performance and ability in male surfers.

Abstract The aim of this study was to evaluate the anthropometric profiles of male surfers and to investigate the relationship of these measures with performance and ability. Following institutional ethical approval, 79 male surfers underwent anthropometric assessment. These surfers composed of three sub-groups of professional (n=17; age: 34.12, s =3.81 years, stature: 177.28, s =6.29 cm; body mass: 78.57, s =7.17 kg), junior national level (n=15; age: 15.61, s =1.06 years, stature: 173.86, s =5.72 cm; body mass: 63.27, s =7.17 kg) and intermediate level surfers (n=47; age: 22.47, s =2.80 years, stature: 179.90, s =5.41; body mass: 77.83, s =9.43 kg). The mean somatotype values for the different groups of surfers were found to be 2.48, 5.00 and 1.03 for the professional surfers; 2.18, 3.72 and 3.24 for the junior national surfers and 2.79, 3.57 and 2.42 for the intermediate surfers. Professional surfers were significantly (P < 0.01) more mesomorphic and less ectomorphic than intermediate level surfers. Significant correlations were observed between endomorphy (r = -0.399, P < 0.01), sum of six skinfolds (r = -0.341, P < 0.05), and body fat percentage (r = -0.380, P < 0.01) and the rating of ability among the intermediate group of surfers. Across all participants, the rating of surfer ability was significantly correlated with endomorphy (r = -0.366, P ≤ 0.01), mesomorphy (r = 0.442, P < 0.01), sum of six skinfolds (r = -0.274, P < 0.05) and body fat percentage (r = -0.268, P < 0.05). Findings suggest that the levels of adiposity and muscularity may influence the potential for progression between intermediate and professional-level surfing performance.

Red shirt colour is associated with long-term team success in English football.

The colour of sportswear has been shown to influence the outcome of bouts for several different combat sports. The generality of these effects, and whether they extend to collaborative forms of contests (team sports), is uncertain. Since 1947, English football teams wearing red shirts have been champions more often than expected on the basis of the proportion of clubs playing in red. To investigate whether this indicates an enhancement of long-term performance in red-wearing teams, we analysed the relative league positions of teams wearing different hues. Across all league divisions, red teams had the best home record, with significant differences in both percentage of maximum points achieved and mean position in the home league table. The effects were not due simply to a difference between teams playing in a colour and those playing in a predominantly white uniform, as the latter performed better than teams in yellow hues. No significant differences were found for performance in matches away from home, when teams commonly do not wear their "home" colours. A matched-pairs analysis of red and non-red wearing teams in eight English cities shows significantly better performance of red teams over a 55-year period. These effects on long-term success have consequences for colour selection in team sports, confirm that wearing red enhances performance in a variety of competitive contexts, and provide further impetus for studies of the mechanisms underlying these effects.

Addressing the issue of e-learning and online genetics for health professionals.

Health-care professionals need an appropriate genetics knowledge base to care for patients and their families. However, studies have indicated that nurses and midwives lack the requisite genetics knowledge to practice effectively and safely, with a paucity of resources to address their educational needs. This paper describes an action research study aimed at developing an online genetics resource for students and practitioners in a range of health professions. A literature review of current health-care genetics education was undertaken. In the first phase of the action cycle, a sample of nurses and midwives were surveyed using a questionnaire to discover their perceived learning needs and the acceptability of an e-learning approach. Using the findings, an online resource for health professionals was developed, by means of a life stage structure to expedite accessibility. The developmental process leading to the construction of clinical case studies in this resource (including theory, ethical, and practical issues) and the evaluation strategy are discussed.

Supporting biosciences in the nursing curriculum: development and evaluation of an online resource.

AIMS: The aim of this project was to develop and evaluate an online resource designed to improve the biosciences knowledge of preregistration nursing students. BACKGROUND: A number of studies have identified lack of biological subject knowledge and anxiety about studying biosciences as serious problems for nursing students. The availability of a contextualized biological information resource prior to and early in their studies might help to reduce this fear and anxiety. METHODS: The project used an action research approach, involving an initial analysis of the extent of the problems with biosciences encountered by our nursing students, followed by the development and evaluation of a biology-based open learning resource (entitled Headstart) in collaboration with preregistration nursing students and nurse educators. FINDINGS: The students in this study expressed a high level of concern about studying biology, and perceived this to be the most difficult aspect of their nursing programme (significantly more difficult than nursing practice). A significant correlation was also found between previous level of biological qualification and confidence in passing module tests. Evaluation of the new online resource illustrated the willingness of nursing students to use such a package, and general approval of its content and mode of delivery, despite a number of problems related to computer access and students' inexperience with information technology. CONCLUSIONS: This project has provided further evidence of the need for additional resources in biosciences for nursing students. It has also illustrated the way in which a targeted online resource has the potential to provide substantial benefits in terms of supporting the nursing curriculum. Whilst further evaluation is needed, the findings suggest that Headstart has the potential to address a number of issues identified both by this study and by previous research in nurse education.
