Background
The block phase in the swimming start requires a quick reaction to the starting signal and a large take-off velocity that is primarily horizontal in direction. Due to the principle of specificity of training, there is a potential benefit of performing a greater proportion of horizontal force production exercises in a swimmers’ dry-land r...

Context 1
... direction specific lower body jump was added in the second phase for each group (weeks five to eight) ( Table 1). The HF training group was prescribed a 'start jump' which is a jump for horizontal distance initiated from a mimicked swim start position ( Fig. 1), while the VF training group performed the squat jump. When performing the jumps, the HF group were instructed to jump as far forward as possible, while the VF group were instructed to jump as high as possible with each ...

... The first study was able to have such results due to the duration of the programming, with swimmers achieving improved performance over the weeks. The study by Thng et al. [38] compares the effects of programming focused on vertical vector strength exercises with programming focused on horizontal vector strength exercises, including traditional and plyometric exercises. The results appear to be similar, with no observable improvement in swimming performance. ...
Aims. — Strength training is not usually an important aspect of the training programme forswimmers. Instead, more emphasis is placed on traditional swimming training, which focusesmainly on endurance work.News. — This is why in this study a systematic review is carried out with the aim of observing theeffects that can be caused by a swimming training programme in which strength work is carriedout, while maintaining traditional swimming training. Considering the PRISMA statement, theWeb of Science (WOS) database was used to search for articles, taking those published between2017 and 2022. A total of 387 articles were identified, from which, after passing all criteria,19 were chosen as the study sample. After analysis, it was found that addressing strengthenhancement work within programming can have a positive transfer on short-medium distance swimming performance, improving force transmission and stroke biomechanics.
Conclusion. — This indicates that it would be appropriate to plan the training microcycles withstrength sessions separated from the swimming sessions, without increasing the training volumetoo much, so as not to cause greater fatigue in the swimmer.
The aim of the research is to a comparison between two methods of power training, strength-speed and speedstrength
on the performance of 50-meter freestyle swimming. The experimental method was applied to a sample of 12 adult
swimmers (mean +/-SD: 16 +/-1 year, 172.2+/-3.2cm, 78.2+/-2.3kg) divided into two experimental groups, group A (strengthspeed)
and group B (speed-strength) by applying pre-and post-measurements,1RM bench press, 1RM squat, medicine ball
chest throw, vertical jump, stroke length (SL), stroke rate (SR) and 50-meter freestyle tests was applied on the subjects
respectively, Statistical Analyses Repeated-measures analysis of variance (ANOVA) was used to compare 50-meter freestyle
trial time performance after the 2 different power training methods. Statistical significance was accepted at (p <0.05), (p <0.01).
A 6-week power training program was applied 3 times a week, results show significant differences between pre and postmeasurements
in stroke length (t=3.64) and stroke rate (t=7.00) in group A, 1RM squat (t=3.60), vertical jump (t=4.96), stroke
length (t=6.76) and 50-meter freestyle (t=32.91) in group B, and non-significant differences in 1RM bench press (t=2.33),
1RM squat (t=2.22), chest MD ball throw (t=2.35), vertical jump (t=2.18), and 50-meter freestyle (t=1.93) in group (A),1RM
bench press (t=2.61), chest MD ball throw (t=2.08) and stroke rate (t=1.40) in group (B) for post-measurements. Present results
recommend that dry-land program training must include the two methods of power training, strength-speed, and speed-strength,
based on the force-velocity relationship for sprint swimmers during a specific period, power training in these two methods
improves stroke length, and stroke rate and it leads to enhance swimming performance in sprint events.
