“…In the present experiment, the Swimming Pace Control System (SPCS) device (Creosiv, PL) was used to provide visual information about the flow velocity in real-time (online) (Szczepan, Zatoń, 2017). In the past, devices such as Lap Track (Finis, USA) have been used for the same purpose and are displayed on the pool wall, or a hand chronometer (SportCount Chrono, USA).…”

Controlling swimming speed is an important factor as far as accomplishing swimming training tasks is concerned. The aim of this study was to determine the importance of visual information about control of swimming speed in threshold training for swimmers. Six swimmers took part in this experiment. The study consisted of two exercise tests in which the participants swam 10 × 100 m. Individually designated task time corresponded to intensity of 95-100% of anaerobic threshold (AnT) intensity. AnT was determined in a progressive test prior to the experiment. In the first exercise test participants did not receive information regarding their swimming speed. In the second test visual information regarding their swimming speed was transmitted in real time using the Swimming Pace Control System device. The effect of visual control of swimming speed in threshold training for swimmers was determined by measuring the time needed to complete the test distances, heart rate and lactate concentration. Visual information used in swimming speed control in real-time statistically significantly reduces the differences between the assumed and actual time needed to complete the test distance (p = 0.057). Visual control of swimming speed resulted in an appropriate level achievement of intensity for threshold training, which was measured by swimming time (inaccuracỳx6.97 ±1.38 s), heart rate (x162.7 ±15.9 beat/min), and lactate concentration (x4.70 ±1.78 mmol/l). Comparing the increase in lactate concentration and exercise test with visual information, statistically significant differences are not observed (p = 0.710, p = 0.947). However, among 33.33% of the subjects, lactate concentration after training without visual information did not meet the standards (4 to 5 mmol/l) of threshold training (8.85 mmol/l and 14.57 mmol/l). Additionally, value of standard deviations of lactate concentration after threshold training with visual information amounted to 37.87% mean of lactate concentration, and in the condition without information 84.00% mean of lactate concentration. The results indicate the need to use concurrent visual information provided in real-time allowing you to control the swimming speed in swimming training.

“…A beam of light from the SPCS device covered the distance precisely within the time which had been designated for each participant prior to the experiment. A validation test of SPCS was completed with an accuracy of ±200 ms (Szczepan, Zatoń, 2017).…”

“…Other aids that exist on the market include an underwater device that provides lap timing and counting information such as the Lap Track (Finis, USA) or the Chrono hand chronometer (SportCount, USA). Similar variants of the above include the Pacer (GBK Electronics, Portugal), Pace2Swim (FADEUP, Portugal), SwimLead (Synerte, Poland), or Swimming Pace Control System (Creosiv, Poland) [39]. The aforementioned devices all provide some form of visual feedback and have been found to improve movement execution.…”

Background:The aim was to compare the effects of two different types of concurrent feedback administration on biomechanical performance during a swimming-specific task. Material and methods:A counterbalanced repeated measures design was used to compare the execution of the butterfly stroke (the propulsion phase only) on a modified Smith machine. Twenty repetitions were performed in each condition of feedback (visual vs. verbal). Fourteen college swimmers (age x̄ = 22.21 ±1.85 years, height x̄ = 173.71 ±8.65 cm, mass x̄ = 71.32 ±10.64 kg) were recruited. An incremental force test was administered for each participant to determine the mean propulsive velocity in which maximal power was produced. Feedback addressed correct execution velocity of the pulling movement that corresponded to the maximal power production as determined in an incremental force test.Results: T testing revealed no statistically significant differences between the verbal and visual feedback conditions. Visual feedback elicited a correct response in 76.11% of total feedback compared with 72.06% in the verbal feedback condition.Conclusions: Considering total feedback response, the visual feedback condition elicited 4.05% more correct responses than verbal feedback. However, this difference did not attain statistical significance and, therefore, the underlying hypothesis could not be confirmed.

“…Maintaining exercise intensity was evaluated by lactate concentration. the method can allow swimmers not only to meet training goals but also to augment training on the basis of their own individual needs [22]. It is worth to note that although Lider is a technical device, it can be used in swim training without restricting the swimmers' movements, which could potentially affect their achievement.…”

Purpose. Effective control of swimming speed can increase training effectiveness and therefore enhance training adaptations. the aim of the present study was to investigate the effects of concurrent visual feedback on swimming speed at an exercise intensity above the onset of blood lactate accumulation (OBLA). Methods. the study involved 12 healthy male and female swim team members. the participants executed two 200-m freestyle trials within an individually predetermined swim time matching an exercise intensity above OBLA (exercise zone 4). In one trial, no additional information was provided, whereas concurrent visual feedback was given on swimming speed in the other. Results. concurrent visual feedback narrowed the discrepancy between the predetermined and obtained swimming times (p < 0.001). this improvement in swimming time (accuracy) showed a negative correlation with the increase in post-trial lactate concentration. the correlation between the difference in the predetermined and obtained times and the increase in lactate was R =-0.46 when no visual feedback was provided but R =-0.64 with visual feedback, with the latter result statistically significant (p = 0.024). Conclusions. concurrent visual feedback allows swimmers to consistently maintain a predetermined swimming speed and therefore keep the specified exercise intensity as evidenced by the increase in lactate concentration. this can result in more effective execution of training goals and thereby enhance training outcomes.
