“…After completing a standard warm–up, swimmers were instructed to perform a freestyle track start until a distance further than 15 m to ensure representative values of the time to 15 m (Barlow et al, 2014), however, respecting the FINA rules which determine that by the 15 m point the head must have broken the surface. A standardized starting procedure was used.…”

“…Overall swimming start performance in competitions is commonly defined as the time to 15 m (Barlow et al, 2014; Seifert et al, 2010; West et al, 2011) and consists of the block, flight, entry, glide and underwater propulsion phases (Vantorre et al, 2014). Two distinct actions must be optimized during the block phase: a reaction to the start signal and a force impulse generated over the starting block (Benjanuvatra et al, 2007; Vantorre et al, 2014).…”

This study aimed to examine the correlation of different dry land strength and power tests with swimming start performance. Twenty international level female swimmers (age 15.3 ± 1.6 years, FINA point score 709.6 ± 71.1) performed the track freestyle start. Additionally, dry land tests were conducted: a) squat (SJ) and countermovement jumps (CMJ), b) squat jumps with additional resistance equivalent to 25, 50, 75 and 100% of swimmers’ body weight [BW]), and c) leg extension and leg flexion maximal voluntary isometric contractions. Correlations between dry land tests and start times at 5, 10 and 15 m were quantified through Pearson’s linear correlation coefficients (r). The peak bar velocity reached during the jumps with additional resistance was the variable most correlated to swimming start performance (r = -0.57 to -0.66 at 25%BW; r = -0.57 to -0.72 at 50%BW; r = -0.59 to -0.68 at 75%BW; r = -0.50 to - 0.64 at 100%BW). A few significant correlations between the parameters of the SJ and the CMJ with times of 5 and 10 m were found, and none with the isometric variables. The peak velocity reached during jumps with external loads relative to BW was found a good indicator of swimming start performance.

“…Similar to the Omega official claims that the footrest enables the athlete to push-off with a rear knee angle of 90°, the best starts produced a peak vertical force at a rear knee angle of 80°-90° which is beneficial to starting performance, while knee angle of 100°-110° for the best starts to product the peak horizontal force (S. E. Slawson, Chakravorti, Conway, Cossor, & West, 2012). Furthermore another study suggested that developmental level swimmers should choose between a neutral-weighted or rear weighted position on the new OSB11 starting blocks when using KS (Barlow, Halaki, Stuelcken, Greene, & Sinclair, 2014). A narrow stance on this new block was helpful to get larger advantages in the block time and horizontal peak force and a high the centre of mass position to improve swim-start performance (Kibele, Biel, & Fischer, 2016).…”

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.

Different Lower-Limb Setup Positions Do Not Consistently Change Backstroke Start Time to 10 m

Backstroke starts involve the athlete starting from a flexed position with their feet against the pool wall and then extending their ankles, knees, hips and back to push off; however, swimmers can start in different positions. The purpose of this study was to evaluate the performance impact of different knee extension angles in the setup position for a backstroke start. Ten backstroke swimmers completed maximum-effort starts in each of two setup positions: one with the knees maximally flexed, and one with the knees less flexed. The start handles and touchpad were instrumented with multi-axial force sensors. Activity of major hip and knee extensors was measured using surface electromyography. Body position in the sagittal plane was recorded using high-speed cameras. There was no overall difference in time to 10 m between the two conditions (p = 0.36, dz = 0.12), but some participants showed differences as large as 0.12 s in time to 10 m between start conditions. We observed that starts performed from a setup position with less knee flexion had an average 0.07 m greater head entry distance (p = 0.07, dz = 0.53), while starts from a setup position with maximal knee flexion had an average 0.2 m/s greater takeoff velocity (p = 0.02, dz = 0.78). Both head entry distance and takeoff velocity are related to start performance, suggesting each position may optimize different aspects of the backstroke start. Coaches should assess athletes individually to determine which position is optimal.
