“…In the present study, the highest values of speed in the FINS condition led to the highest values of estimated energy cost. This needs to be considered when the swimmer uses FINS at supra-maximal swimming speeds to actually cause changes in the energy expended to move the body forward ( Matos et al, 2013 ). In other words, the use of FINS at low swimming speeds would contribute little to the physiological adaptations resulting from the increased drag that occurs at high swimming speeds ( Truijens and Toussaint, 2005 ).…”

“…Using paddles or fins can lead to spatiotemporal changes in the swimming cycle that can have an influence both on the production of propulsive forces and on swimming technique. Since paddles and fins need less physiological demands (blood lactate concentration and rate of perceived exertion) for the same swimming speed without equipment ( Matos et al, 2013 ), the best gains related to the use of both should occur when swimming training is performed at higher intensities, for a longer period. When swimming speed is increased (to supramaximal speeds) with the equipment, drag increases in a square function of the speed increased, so that to overcome this drag, the swimmer must apply more force in the water.…”

“…But, in the meantime, the continuous kicking action visible during sprints may raise the energy cost of swimming, as stated by Zamparo et al (2020) . In turn, it will tend to affect arm stroke efficiency (as an increase in the ratio of total work produced by the swimmer to useful work, that which actually takes the swimmer forward; di Prampero, 1986 ) by increasing swimming speed and decreasing stroke rate ( Matos et al, 2013 ). To go deeply, the fin design (size, but also flexible vs. rigid materials that composed the fins) may also impact kinematics and propulsive swimming efficiency ( Zamparo et al, 2002 ).…”

Effects of paddles and fins on front crawl kinematics, arm stroke efficiency, coordination, and estimated energy cost

Paddles and fins are used in swimmers training with different objectives (e.g., increase propulsive areas of hands and feet, improve the feeling of water flow). These artificial modifications of the stroke might be viewed as external constraints of the stroke task, both will either disturb or facilitate swimming modalities, so the coaches should manipulate its use to extract benefits for performance. This study seeks to investigate the precise effects of wearing either paddles (PAD) or fins (FINS) vs. a no-equipment (NE) trial in three all-out front crawl exercises on swimmer kinematics, arm stroke efficiency (ηp), upper-limbs coordination patterns (Index of Coordination, IdC), and estimated energy cost (C). Eleven regional to national-level male swimmers participated in the study (age: 25.8 ± 5.5 years, body mass: 75.2 ± 5.5 kg, height: 177 ± 6.5 cm) and were recorded from both sides of the swimming pool to collect all variables. Repeated measures ANOVA and Bonferroni post hoc were used to compare the variables. Effects sizes were calculated. Time to cover the distance and velocity were higher in FINS swimming, with larger values of stroke length (SL) and lower kick amplitude in comparison to the other trials (PAD and NE). The use of FINS also modified the stroke phases durations by presenting significant lower propulsion time during the stroke in comparison to PAD or NE. Values of IdC were lower (IdC < −1%, so catch-up pattern of coordination) for FINS in comparison to NE. In terms of ηp, using PAD or FINS demonstrate higher arm stroke efficiency than swimming without equipment. Finally, C was significantly higher in FINS swimming in comparison to NE and PAD. From the present results, it should be noted that the use of equipment such as fins deeply modify the structure of the swimming stroke (from the performance-related parameters through the kinematics of both upper and lower limbs to the stroke efficiency and coordination pattern). So, using equipment should be appropriately scaled by the coaches to the objectives of the training session in swimming, and in emergent sports such as “SwimRun”, paddles and fins must be viewed as tools to achieve higher velocities to cover a given distance.

“…In order for swimmers to achieve optimal race performance, certain equipment is used for training. Hand fins, kickboards, pull-buoys, snorkels, and fins are all examples of equipment used in swimming (Matos et al, 2013;Jagomägi and Jürimäe, 2005;Agopyan et al, 2012). Studies have indicated that flutter kicks contribute to around 10% of the overall stroke rate (Hollander et al, 1988).…”

“…Previous studies have investigated the effects of training equipment on swimmers' performance. It is proposed that equipment plays a crucial role in enhancing speed and muscle strength in younger age groups (Zamparo et al, 2002;Matos et al, 2013). Nonetheless, the immediate effects of commonly used equipment such as fins, kickboards, and pull-buoys on freestyle swimming performance, and whether performance differs depending on the equipment used, have yet to be explored.…”

The present study sought to examine the freestyle proficiency of juvenile swimmers deploying various accessories, namely fins, kickboard, and pull-buoy. Twenty-three participants, comprising 14 females and 9 males aged between 10 and 11 years, who reside in Istanbul, pursue activities in exclusive clubs, have held an athlete license for no less than three years, and expressed a keen interest in swimming opted to take part in the study. The research was implemented voluntarily in a private club's indoor swimming pool (25 m short lane). First, the swimmers' body weight, height, and arm length were measured. They then demonstrated their freestyle performance at distances of 25 m, 50 m, 75 m, and 100 m using different equipment: maximal, fins, pull-buoy, and kickboard-only flutter kick. Swimming performances with each piece of equipment were performed two days apart, and all swimmers' performances were recorded with an SJCAM 4k external camera. After conducting the test, the captured images were transferred to the computer and processed using the Kinovea 0.9.5 program in MP4 format. Individual calculations were made for each swimmer's finish time, lap times and velocity for each distance and equipment. The data were evaluated using the IBM SPSS 24.0 analysis program. It was ensured that the data followed a normal distribution ("±1.5"). The comparison of finish times, lap times and velocity of swimmers using different equipment was analysed using repeated measures variance. There was a statistical difference between the fins, kickboard and pull-buoy in finish time, lap times and velocity (p

The objective of this study was to evaluate the impact of augmenting the foot area (by wearing fins) on the load-velocity relationship of the underwater dolphin kick (UDK) and to investigate the optimal loading zone of resistance training for the UDK. Seventeen swimmers underwent a semi-tethered swimming test and a 15-m maximum swim velocity test, both with and without fins (FINS and WF, respectively). The study revealed that the UDK's load-velocity relationship, when using semi-tethered swimming, displayed a robust linear correlation (R2 = 0.88 ± 0.15). The FINS condition enhanced the optimization of the load-velocity relationship, resulting in a substantial rightward shift (R2, AIC, BIC optimized by 15%–65%) and elevating the UDK velocity by 10%–22% across seven load levels. The effective load level rose from 57 N to 69 N (R = 0.70–0.85, p < 0.05); however, the FINS condition altered the original UDK technique, leading to a 7% decrease in the stroke rate (SR) and a 19% increase in stroke length (SL). Consequently, wearing fins modified the load-velocity relationship of the UDK and augmented the power output level. We recommend that athletes use semi-traction swimming to improve UDK performance with a maximum load of no more than 57 N or a velocity of no less than 73% of maximum velocity; wearing fins allows this range to be extended to 69 N and 71% of maximum velocity.
