“…Between block versions, the BT reduction in the new block can be related to variations in feet geometry, joint angles and gravity center position (Kibele et al, 2015;Slawson et al, 2012;Slawson et al, 2011). Furthermore, to justify these variations, Kibele et al (2015) shows an average improvement of 0.06s up to 0.14s in the BT by kinematical adjustments in preferred swimmers positions in block start.…”

“…Changes that occurred in FINA rules (SW 7; FR 2.7) at the FINA World Championships (Rome, 2009) (K. De Jesus et al, 2013Honda et al, 2012;Kibele et al, 2015), resulted in a large amount of studies that have investigated the impact of the new block (OSB11) configuration on swimming performance (Garcia-Hermoso et al, 2013;Slawson et al, 2011;Takeda et al, 2012). Those changes were, for example, the inclusion of an "adjustable, slanted footrest" to ventral strokes (butterfly, breaststroke and freestyle) (Vantorre et al, 2014) and three different start handgrips (i.e., two horizontal and one vertical) for dorsal stroke (backstroke) (K. De Jesus et al, 2014).…”

In high level championships small details are able to define the swimming medalists. Overall 0.01 s represents just a short piece of swimming final time, but between elite swimmers just 1.12% of the final time performance in 50 meters freestyle are improved annually. In this perspective greater block time differences over swimming final time differences could change the importance of block time to the swimmers classification. Thus the aim was to investigate the influence of block time in the final sprint events (50 and 100m) classification, including seven FINA World Championships (2003-2015). Thereunto, were calculated the frequency of possible Classification Changes (CC), based on differences between block times (BT) and final times (FT) in each swimming event. Public data was collected at the Omega Timing website. Totally, 112 events and 894 individual results (447 men and 447 women) were analyzed. The Chi-Square test was used to verify the Classification Changes occurrence between strokes (freestyle, backstroke, breaststroke and butterfly), event distances (50 and 100m), sex (male and female), block versions (traditional block used by FINA until 2007-OSB9; and new block

“…Peak forces produced by the KS on land was correlated to greater flight distance . Narrow stance on the OSB11 block in the KS also was reported to take advantage in flight distance (S. E. Slawson et al, 2011). This result might due to the narrow stance on the new block generated larger horizontal peak force (Kibele, Biel, & Fischer, 2014).…”

The new starting block by Omega firstly appeared in Beijing Olympic Games since the FINA (Fédération Internationale de Natation) amended the rule (OSB11, Corgémont, Switzerland). And this new start block gave rise to the researchers and academics focused more on the start techniques on this new start block. The aim of this study is to summarize the current literature regarding the kinematics research progress of swimming start on this new start block and find the proper swim-start to optimize the swimming performance. The aim of this study is to provide insight into the improvement of swimming performance on the new start block by kinematics view for coaches and athletes. Results suggest that the KS is superior to the TS and GS. With the introduction of the OSB11 starting plate, swimmers need to quickly modify and adjust their techniques to take advantage of the new swimming start plate during normal training. The swimmers should not only enhance their speed training and speed training methods but also strengthen the core and lower limb strength to obtain the best take-off forces and horizontal velocity.

“…The force and impulse of the swimmer have been investigated separately using a force measurement platform developed at Loughborough University. 12 Velocity and distance measurements have been considered within a separate publication by Le Sage et al 13 Video analysis is the most popular form of performance analysis in swimming 14 because the system is remote from the swimmer, making it unencumbering and unobtrusive. Video cameras require relatively low skill levels for operation.…”

A wireless sensor network has been developed and used to monitor the important performance parameters pertaining to a swimmer's start. The variables identified as important include time to back foot leaving the block, time to hip entry into the water, time to first kick, time to first stroke, number and rate of the underwater kick and stroke count and rate. These parameters were specified by the users (coaches, biomechanists and swimmers) of the system. The measurements were validated against the vision analysis system currently used during in-water training with the national swimming team. From the results, it can be suggested that the wireless sensor network can be used as an automated system for monitoring performance parameters considered of importance to the user during the swimming start.
