Simulating the Blade-Water Interactions of the Sprint Canoe Stroke

Morgoch, Dana January 2016 (has links)
As a sprint canoe athlete takes a stroke, the flow around their blade governs the transfer of power from the athlete to the water. Gaining a better understanding of this flow can lead to improved equipment design and athlete technique to increase the efficiency of their stroke. A method of modelling the complex motion of the sprint canoe stroke was developed that was able to simulate the transient 2-phase blade-water interactions during the stroke using computational fluid dynamics (CFD). The blade input motion was determined by extrapolating the changing blade position from video analysis of a national team athlete. To simulate the blade motion a rigid inner mesh translated and rotated according to the extrapolated blade path while an outer mesh deformed according to the translation of the inner mesh; allowing for independent motion of the blade throughout the xy-plane. Instabilities associated with the blade piercing a free surface were dealt with by using a piecewise solution. The developed model provided a first look into the complex hydrodynamics of the sprint canoe stroke. Examination of the resultant flow patterns showed the development and shedding of tip and side vortices and the resultant pressure on the blade. Late in the catch, there was an unrealistic drop in the net force on the blade which was attributed to the over-rotation of the blade causing the top two-thirds of the blade to accelerate the near surface water forward. The inclusion of an approximated shaft flexibility showed the ability to improve the net force to more realistic values. / Thesis / Master of Applied Science (MASc)

Energetics in Canoe Sprint

Li, Yongming 11 May 2015 (has links) (PDF)
This study reviewed first the development of race result in canoe sprint during the past decades. The race results of MK1-1000 and WK1-500 have increased 32.5 % and 42.1 %, respectively, a corresponding 5.0 % and 6.5 % increase in each decade. The development of race results in canoe sprint during the past decades resulted from the contributions of various aspects. The recruitment of taller and stronger athletes improved the physiological capacity of paddlers. Direct investigation on energy contribution in canoe sprint enhanced the emphasis on aerobic capacity and aerobic endurance training. Advancement of equipment design improved the efficiency of paddling. Physiological and biomechanical diagnostics in canoe sprint led to a more scientific way of training. Additionally, other aspects might also have contributed to the development of race results during the past decades. For example, the establishment of national team after World War II provided the possibility of systematic training, and the use of drugs in the last century accelerated the development of race results in that period. Recent investigations on energetics in high-intensity exercises demonstrated an underestimate of WAER % in the table provided by some textbooks since the 1960s. An exponential correlation between WAER % and the duration of high-intensity exercises was concluded from summarizing most of the relevant reports, including reports with different methods of energy calculation. However, when reports with the MAOD and Pcr-La-O2 methods were summarized separately, a greater overestimate of WAER % from MAOD was found compared to those from Pcr-La-O2, which was in line with the critical reports on MAOD. Because of the lack of investigation of the validity of the comparisons between MAOD and Pcr-La-O2, it is still not clear which method can generate more accurate results and which method is more reliable. With regard to kayaking, a range of variation in WAER % was observed. Many factors might contribute to the variation of WAER % in kayaking. Therefore, the methods utilized to calculate the energy contributions, different paddling conditions, and the level of performance were investigated in kayaking. The findings indicated that the method utilized to calculate the energy contributions in kayaking, rather than paddling condition and performance level of paddlers, might be the possible factor associated with WAER %. Some other possible factors associated with WAER % still need to be further investigated in the future. After verifying the dependence of WAER % on the method of energy calculation, but not on paddling condition and performance level of paddlers, energy contributions of kayaking were investigated for the three racing distances on a kayak ergometer with junior paddlers. Energetic profiles in kayaking varied with paddling distances. At 500 m and 1000 m the aerobic system was dominant (with WAER % of 57.8 % and 76.2 %), whereas at 200 m the anaerobic system was dominant (with WAER % of 31.1-32.4 %). Muscular volume seemed to have an influence on absolute energy productions. The anaerobic alactic system determined the performance during the first 5 to 10 s. The anaerobic lactic system probably played a dominant role during the period from the 5th-10th s to 30th-40th s. The aerobic system could dominate the energy contribution after 30–40 s. This energetic profile in kayaking could provide physiological support for developing the training philosophy in these three distances. Additionally, the method introduced by Beneke et al. seemed to be a valid method to calculate the energy contributions in maximal kayaking. Energy contributions in canoeing were similar to those in kayaking. The relative energy contributions on open water canoeing were 75.3 ± 2.8 % of aerobic, 11.5 ± 1.9 % of anaerobic lactic, and 13.2 ± 1.9 % of anaerobic alactic at maximal speed of simulated 1000 m. Further, the C of canoeing seemed also to be similar to the reported findings in kayaking, with a function of y = 0.0242 * x2.1225. Training programs could be designed similarly for kayaking and canoeing with regard to energetic profile. In order to extend the findings on energetics in canoe sprint to other exercises, energy contributions in kayaking, canoeing, running, cycling, as well as arm cranking were compared with the same duration. Results indicated that WAER % during maximal exercises with the same duration seemed to be independent of movement patterns, given similar VO2 kinetics during the maximal exertion. The exponential relationship between WAER % and duration in maximal exercises could be supported by excluding the influence from movement patterns. Additionally, MLSS in kayaking was investigated. The blood lactate value of MLSS was found to be 5.4 mM in kayaking, which could expand the knowledge of MLSS in different locomotion. The MLSS in kayaking might be attributed to the involved muscle mass in this locomotion, which could result in a certain level of lactate removal, and allow a certain level of equilibrium between lactate production and removal. LT5, instead of LT4, was recommended for diagnostics in kayaking, given an incremental test as used in this study.
