“…The SR is similar between sport classes S7-S10 according to the results of the metaanalysis (sport classes with lower physical disabilities) for male swimmers in the 100 m. However, there are also similarities between sport classes S2-S6 for the meta-analysis (sport classes with the greatest physical handicaps) in the 100 m. Female swimmers showed no heterogeneity in a broader range for meta-analysis (sport classes S3-S8 and S9-S10) in the 100 m. Differences in SS are reported with increases in SL at a low SR among swimmers with conventional anatomy (Craig & Pendergast, 1979;Craig, Skehan, Pawelczyk, & Boomer, 1985). However, if SL is short, the swimmer will have to increase SR to swim faster (Figueiredo et al, 2014), as occurs in short events (Ferreira et al, 2012). There is a relationship between SL and SS, as swimmers present great functional ability (Pelayo et al, 1999) and men have a longer SL than women, but without differences in SR (Daly et al, 2003;Daly, Malone, Vanlandewijck, & Steadward, 1999b).…”

Biomechanical and coordination measurements are useful tools to assess swimming performance. Regarding Paralympic swimming, function and technique make these measurements complex. The aim of this study was to perform a systematic review of studies on biomechanics, coordination and performance in disabled swimmers following swimming protocols and in competitions. Data sources: PubMed, EMBASE, ISI Web of Knowledge, SPORTDiscus and Academic Search Premier. We selected complete studies, published until June 2018. Eighteen studies satisfied the inclusion criteria and were selected for qualitative analysis; nine of these were included in the meta-analysis. Swimming speed and stroke length increase with less impact of physical, visual and intellectual impairment on performing specific swimming tasks. Stroke rate is more stable all through the sport classes than both swimming speed and stroke length. Most physically disabled swimmers adopt the catch-up coordination model. Stroke rate is responsible for most of the intracycle velocity variation in swimmers with amputations or malformations of the upper limbs. No study was found on propulsive efficiency. Swimmers with disabilities should work more on stroke rate, with small decreases in stroke length to achieve higher swimming speeds, lower swim coordination index (more negative) and lower speed variations.

“…Over the past few years, there has been growing interest in the determinants of competitive performance in swimming (Franken et al, 2007;Geladas et al, 2005;Marinho et al, 2011;Vantorre et al, 2014). Swimming is characterized as a complex modality, where the economy of movement, muscular strength, speed of displacement, reaction time, and ability to overcome difficulties inherent in the physical and mental processes of training and competition positively or negatively influence the gain in sports performance (Ferreira et al, 2012). Thus, swimming is associated with several factors (i.e., anthropometric, biomechanical, energetic, hydrodynamic) that are considered to be determinants of performance and are fundamental to the sport (Franken et al, 2008).…”

The aim of this study was to characterize and compare the anthropometric characteristics and the explosive muscular strength of the upper and lower limbs in swimmers at the U-16 and U-15 level. In addition, the relationship between anthropometric characteristics, strength variables and performance in the 50 m freestyle was verified. All participants were analysed, regarding their anthropometric characteristics, their explosive muscle strength, and their performance in the 50 m freestyle swim. A total of 92 female swimmers (mean ± standard deviation: 14.08 ± 0.56 years old) participated in the study. The results showed that sub-16 swimmers had higher body mass values compared to sub-15 swimmers (p < .01). In addition, statistically significant differences were also found for upper limb strength indicators (p < .05). Finally, although no differences were found for performance in the 50 m freestyle test between the groups analysed, it was found that swimmers swam with different biomechanical patterns. It was concluded that although there were significant differences for the anthropometric indicators and explosive strength variables, the performance in the 50 m freestyle did not show any statistically significant variations, however the two groups of swimmers, swam with different biomechanical patterns.

ObjectiveTo validate an equation to estimate the maximal oxygen consumption (VO2max) of nonexpert adult swimmers.MethodsParticipants were 22 nonexpert swimmers, male, aged between 18 and 30 years (age: 23.1 ± 3:59 years; body mass: 73.6 ± 7:39 kg; height 176.6 ± 5.53 cm; and body fat percentage: 15.9% ± 4.39%), divided into two subgroups: G1 – eleven swimmers for the VO2max oximetry and modeling of the equation; and G2 – eleven swimmers for application of the equation modeled on G1 and verification of their validation. The test used was the adapted Progressive Swim Test, in which there occurs an increase in the intensity of the swim every two laps. For normality and homogeneity of data, Shapiro-Wilk and Levene tests were used, the descriptive values of the average and standard deviation. The statistical steps were: (1) reliability of the Progressive Swim Test – through the paired t-test, intraclass correlation coefficient (ICC), and the Pearson linear correlation (R) relative to the reproducibility, the coefficient of variation (CV), and standard error measurement (SEM) for the absolute reproducibility; (2) in the model equation to estimate VO2max, a relative VO2 was established, and a stepwise multiple regression model was performed with G1 – so the variables used were analysis of variance regression (AR), coefficient of determination (R2), adjusted coefficient of determination (R2a), standard error of estimate (SEE), and Durbin–Watson (DW); (3) validation of the equation – the results were presented in graphs, where direct (G1) and estimated (G2) VO2max were compared using independent t-test, linear regression (stressing the correlation between groups), and Bland–Altman (the bias agreement of the results). All considered a statistical significance level of P < 0.05.ResultsOn the trustworthiness of the Progressive Swim Test adapted presented as high as observed (R and ICC > 0.80, CV < 10%, and SEM < 2%). In the equation model, VO2max has been considered the third model as recommended due to the values found (AR < 0.01, R = 0795, R2 = 0633; R2a = 0.624, SEE = 7.21, DW = 2.06). Upon validation of the equation, no significant differences occurred between G1 and G2 (P > 0.01), linear regression stressed a correlation between the groups (R > 0.80, P < 0.01), and Bland–Altman plotting of the results was within the correlation limits of 1.96 (95% confidence interval).ConclusionThe estimating equation for VO2max for nonexpert swimmers is valid for its application through the Progressive Swim Test, providing to contribute in prescribing the swimming lessons as a method of evaluating the physical condition of its practitioners.
