“…The presence of larger right hemispheric brain regions associated with visual and spatial functions, a lack of lateralization, and a larger corpus callosum (Witelson 1985) (the brain structure involved in communication across hemispheres) were all suggested as neurological mechanisms for this edge. Applications of the ISH to sport occurred primarily in fencing (Bisiacchi et al 1985;Taddei, Viggiano, and Mecacci 1991;Akpinar et al 2015), where left-handers appeared to have advantages in attentional tasks (in terms of response to visual stimuli), though there were also proponents for this view in other sports such as tennis (Holtzen 2000). The idea that an innate advantage was responsible for the significant over-representation of left-handers in professional sports gradually lost momentum following the works of (Wood and Aggleton 1989;Aggleton and Wood 1990;Grouios et al 2000a).…”

Left-handers comprise approximately 15% of professional tennis players, but only 11% of the general population. In boxing, baseball, fencing, table-tennis and specialist batting positions in cricket the contrast is even starker, with 30% or more of top players often being left-handed. In this paper we propose a model for identifying the advantage of being left-handed in one-on-one interactive sports (as well as the inherent skill of each player). We construct a Bayesian latent ability model in the spirit of the classic Glicko model but with the additional complication of having a latent factor, i.e. the advantage of left-handedness, that we need to estimate. Inference is further complicated by the truncated nature of data-sets that arise from only having data of the top players. We show how to infer the advantage of left-handedness when only the proportion of top left-handed players is available. We use this result to develop a simple dynamic model for inferring how the advantage of left-handedness varies through time. We also extend the model to cases where we have ranking or match-play data. We test these models on 2014 match-play data from top male professional tennis players, and the dynamic model on data from 1985 to 2016.

“…Besides the perceptual motor skills, athletes also displayed better sensorimotor performance in comparison to non-athletes both their dominant and non-dominant arms in many sports (Akpinar & Bicer, 2014;Akpinar, 2015: Akpinar;2016: Akpinar, Sainburg, Kirazci, & Przybyla, 2015Ramsay & Riddoch, 2001). Th e eff ect of long-term practice on sensorimotor performance has also been observed in musicians (Rodrigues, Loureiro, & Caramelli, 2013).…”

Sports participation can improve many cognitive and physical performances. It is important to test diff erent sports in diff erent perceptual and motor tests in order to expose the demands of sports. Thus, in this study, we investigated if there are some perceptual and motor performance diff erences between fencers and aged match sedentary group. Nineteen fencers and nineteen non-fencers performed choice reaction time in an aiming task. Reaction time (RT), accuracy, and velocity of the movements were measured. Results displayed that fencers had signifi cantly faster RT, better accuracy with faster movements compared to non-fencers. These fi ndings suggest that participating a sport requiring fast and accurate pointing movements can modify perceptual and motor performance parameters. Thus, it could be better to select participants who have better perceptual and motor performances. Moreover, speed-accuracy trade off proposed by Fitts (1954) can be altered through long-term sport participation.

“…For sports that require repetitive asymmetrical movements such as rowing, fencing, and golf, athletes develop asymmetrical body characteristics [14][15][16]. Compared with these sports, track cyclists must circle in the same direction, but the cycling movement is symmetrical.…”

OBJECTIVE: To identify muscle imbalances and pelvic tilt with implications for low back pain in Keirin cyclists. METHODS: We enrolled 16 Keirin cyclists (mean age, 32.2 ± 8.6 years) and 16 college students as controls (24.3 ± 2.3 years). We measured pelvic tilt, heel-buttock distance (HBD), iliopsoas flexibility (using the Thomas test), hamstring flexibility (using the straight-leg-raise [SLR] test), finger floor distance (FFD), and isometric and isokinetic hamstring and quadriceps muscle strength. These parameters were compared between the two groups, as well as between the right and left sides, by using the Mann-Whitney U test or unpaired t test. RESULTS: The results of this study revealed a significant anterior pelvic tilt at standing position and significantly higher HBD, SLR, and FFD in the Keirin cyclists than in the controls. The isokinetic muscle strength of the quadriceps and hamstring, and the hamstring-to-quadriceps ratio at high angular velocity were significantly greater in the Keirin cyclists. No significant differences were found between the right and left sides. CONCLUSION: This study revealed that the Keirin cyclists had an anterior pelvic tilt and imbalance in hip muscle flexibility, but the difference between the right and left sides were not significant.
