Biomechanical Parameters

Nowadays, in modern elite sport, the identification of the best training strategies which are useful in obtaining improvements during competitions requires an accurate measure of the physiologic and biomechanical parameters that affect performance. The goal of this pilot study was to investigate the capabilities of the e-Kayak system, a multichannel digital acquisition system specifically tailored for flatwater sprint kayaking application. e-Kayak allows the synchronous measure of all the parameters involved in kayak propulsion, both dynamic (including forces acting on the paddle and footrest) and kinematic (including stroke frequency, displacement, velocity, acceleration, roll, yaw, and pitch of the boat). After a detailed description of the system, we investigate its capability in supporting coaches to evaluate the performance of elite athletes’ trough-specific measurements. This approach allows for a better understanding of the paddler’s motion and the relevant effects on kayak behavior. The system allows the coach to carry out a wide study of kayak propulsion highlighting, and, at the same time, the occurrences of specific technical flaws in the paddling technique. In order to evaluate the correctness of the measurement results acquired in this pilot study, these results were compared with others which are available in the literature and which were obtained from subjects with similar characteristics.

Synchronous Measurement

The full comprehension of the impact with which each force is involved in kayak propulsion is very difficult. The measure of the force on the paddle or the stroke rate only is often not enough for the coach to identify the best actions useful to improve the performances of a kayaker. To this purpose, the synchronous measurement of all parameters involved in the kayak propulsion, both dynamic (force acting on paddle and foot brace) and kinematic (stroke frequency, displacement, velocity, acceleration, roll, yaw, and pitch of the boat) could suggest to the coach more appropriate strategies for better understanding of the paddler’s motion and the relevant effects on the kayak behavior. Some simulation models, as well as measurement systems of increasing complexity, have been proposed in the recent years. In this paper, we present the e-Kayak system: A multichannel Digital Acquisition (DAQ) system specifically customized for flatwater kayaking. The system will be described in depth and its capability investigated through specific measurement results.

SummaryThis paper reports on the perspectives of elite athletes on anti-doping work in general and on the whereabouts system in particular, and uses a figurational perspective to explore the unintended consequences of the planned introduction of the whereabouts system. A cross-sectional survey of all the athletes in the Norwegian registered testing pool (n = 236, response rate = 80.8%) was carried out in 2006, using a structured questionnaire. Overall, 70.6% of the athletes agreed that doping was a problem in elite sport in general, but paradoxically only 17.5% agreed that doping was a problem in their own sport. However, more than four in ten (43%) of the athletes agreed that the whereabouts information system made a contribution to a “cleaner” sport. Some athletes thought the system was unfair. The whereabouts information system had, despite all good intentions, outcomes other than those planned and intended by the WADA. Thus, athletes’ views might fruitfully be integrated with other perspectives when anti-doping work is developed further.

The purpose of this study was to explore the association between coach leadership and the coach-athlete relationship. Eighty-one elite athletes ( M = 20.4 years; SD = 3.8; 58% female and 42% male) responded to questionnaires pertaining to their coaches’ leadership behaviours and the quality of their relationship. The overall model for predicting the quality of the coach-athlete relationship according to perceived coach leadership behaviours explained 61% of the variance. Three transformational leadership behaviours were positively associated with the quality of the coach-athlete relationship: individualized consideration, appropriate role-modelling, and fostering acceptance of group goals and teamwork. Based on a gender comparison, men perceived higher levels of leadership pertaining to role-modelling and intellectual stimulation, in addition to higher levels of quality for the coach-athlete relationship. This research emphasizes the importance of engaging in transformational leadership behaviours with regards to associations with perceptions of the coach-athlete relationship in elite sport contexts.

Semistructured Interviews

Coaching is characterized by an inherent pathos between the goals coaches hope to accomplish and those that are realized (Jones & Wallace, 2005). Coaches can actively enhance the likelihood of optimal outcomes through orchestration, a process of incremental coping intended to create improvement in performance (Jones & Wallace, 2005). The current study explored to what extent pathos also manifests in the lives of elite athletes and whether they engage in processes consistent with orchestration. Semistructured interviews were conducted with 12 National Collegiate Athletic Association Division I student-athletes. Primarily deductive analysis of the qualitative data provided confirmation for four domains: (a) sources of ambiguity created by coaches, (b) other sources of ambiguity within student-athletes’ experiences, (c) attempted strategies for orchestrating the pathos, and (d) relationships are crucial for navigating the pathos. The findings potentially offer an approach to understanding the challenges athletes face, which allows coaches to more accurately provide assistance.
