Accelerometry Measurements of Sprint Kayaks
Michael G. Robinson,Laurence E. Holt,Thomas W. Pelham,Karen Furneaux 한국코칭능력개발원 2011 International Journal of Coaching Science Vol.5 No.1
In flatwater paddling competition, optimal physiological power, effective technique and the correct race strategy are essential for peak performance. However, other important factors are the matching of equipment with athlete and placement order in crews. In this study, an in-board accelerometer measured craft dynamics of the sprint racing K-1 and K-4 with various combinations of international class paddlers. Acceleration values were greater on the right when compared to the left for the K-1 paddler. In the K-4 trails, crew 3 demonstrated greater accelerations, achieved faster times over the measured distance with the fewest number of strokes when compared with crews 1 and 2. Acceleration data sets were consistent with personal observations and video analysis conducted by Olympic coaches. This study clearly demonstrated that acceleration data sets can augment the analysis of performance, match equipment with athlete, identify stroke technique faults, and in the crew selection process.

Background: Golf is a popular sport involving overhead activity and engagement of the rotator cuff (RC). This study aimed to determine to what level golfers were able to return to golf following RC repair, the barriers to them returning to golf and factors associated with their failure to return to golf. Methods: Patients preoperatively identifying as golfers undergoing RC repair at the study centre from 2012 to 2020 were retrospectively followed up with to assess their golf-playing status, performance and frequency of play and functional and quality of life (QoL) outcomes. Results: Forty-seven golfers (40 men [85.1%] and 7 women [14.9%]) with a mean age of 56.8 years met the inclusion criteria, and 80.1% were followed up with at a mean of 27.1 months postoperatively. Twenty-nine patients (76.3%) had returned to golf with a mean handicap change of +1.0 (P=0.291). Golf frequency decreased from a mean of 1.8 rounds per week preinjury to 1.5 rounds per week postoperatively (P=0.052). The EuroQol 5-dimension 5-level (EQ-5D-5L) index and visual analog scale (EQ-VAS) score were significantly greater in those returning to golf (P=0.024 and P=0.002), although functional outcome measures were not significantly different. The primary barriers to return were ipsilateral shoulder dysfunction (78%) and loss of the habit of play (22%). Conclusions: Golfers were likely (76%) to return to golf following RC repair, including mostly to their premorbid performance level with little residual symptomatology. Return to golf was associated with a greater QoL. Persistent subjective shoulder dysfunction (78%) was the most common barrier to returning to golf.
