About this study
Official title: Individual Responses to a Low-Volume, High-Intensity Race-Pace Training Block in Finswimmers From the Antioquia Underwater Activities League: A Prospective Single-Group Case Series
This single-group case series describe individual responses to a 9-week low-volume, high-intensity race-pace training block in 5 finswimmers from the Antioquia Underwater Activities League (LASA), Colombia. The intervention will be oriented towards race-specific swimming paces and will include repeated swimming efforts prescribed according to each athlete's main competitive event. External training load, heart rate, rating of perceived exertion, pace stability, and sport performance were monitored throughout the block. The primary outcome was the change in performance time in each athlete's main competitive event from baseline to post-intervention. The study used an intra-individual descriptive approach and did not include randomisation, a control group, or causal inference.
Read the detailed description
Finswimming is a high-speed aquatic sport in which performance in short and middle-distance events depends on the ability to produce and sustain race-specific velocity. Traditional aquatic training models often emphasise high training volume; however, for events lasting from seconds to a few minutes, race-pace work, neuromuscular quality, and individualised load monitoring may be particularly relevant.
This study follows 5 finswimmers from the Antioquia Underwater Activities League (LASA) during a 9-week low-volume, high-intensity training block. All participants received the same general training approach, but training distances, repetitions, target times, and race-pace references were individualised according to each athlete's main competitive event.
Before the intervention, athletes completed a basic characterisation and a baseline performance assessment using an official competition result. Training target times were estimated from the baseline performance. During the 9-week block, the investigators recorded external load variables, including distance, repetitions, weekly volume, target time, and actual time for each relevant repetition. Internal load were monitored using heart rate and rating of perceived exertion. Pace stability were estimated from repeated times in event-specific distances using descriptive indicators such as mean time, standard deviation, and coefficient of variation.
After the intervention, performance were reassessed in the athlete's main event through an official competition or a comparable standardised control test. Data analysis were focus on individual responses, weekly trends, and descriptive changes from baseline to post-intervention. The study were not include a control group or randomisation; therefore, findings were interpreted as exploratory and non-causal.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Low-volume high-intensity race-pace finswimming trainingBehavioural
The intervention will consist of a 9-week finswimming training block oriented towards race-specific pace. Participants will perform repeated swimming efforts prescribed according to individual target times derived from baseline performance. Training sessions will include event-specific distances, repetitions, recovery periods, and target intensities. External load will be monitored through distance, repetitions, weekly volume, target time, and actual time. Internal load will be monitored using heart rate and rating of perceived exertion. Training volume will be adjusted according to the athlete's event profile and reduced towards the final phase when tapering is required.
| Study group | Role | What they receive |
|---|---|---|
| Low-volume high-intensity race-pace finswimming training | Experimental | Participants will complete a 9-week finswimming training block focused on low-volume, high-intensity, race-pace swimming. Training will be individualised according to each athlete's main competitive event and monitored using external load, heart rate, rating of perceived exertion, and repetition times. Receives: Behavioral: Low-volume high-intensity race-pace finswimming training |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change from baseline in main-event finswimming performance time
Performance time, in seconds, will be recorded for each participant's main competitive event. The baseline value will be obtained from an official competition result or a standardised control test before the training block. The post-intervention value will be obtained from an official competition result or a comparable standardised control test after the 9-week block. A lower time will indicate better performance.
Measured: Baseline and week 9
Secondary outcomes (5)
Change from baseline in mean swimming velocity
Mean swimming velocity will be calculated from the performance distance and time in each participant's main event. Velocity will be expressed in metres per second. A higher value will indicate better performance.
Measured: Baseline and week 9
Weekly external training volume
External training volume will be quantified as the total metres completed per week during recorded race-pace or event-specific swimming repetitions.
Measured: Weekly from baseline to week 9
Weekly mean heart rate during recorded swimming repetitions
Heart rate will be recorded during training sessions using a heart rate monitor, sport watch, or equivalent device. Weekly mean heart rate will be reported in beats per minute.
Measured: Weekly from baseline to week 9
Weekly rating of perceived exertion
Rating of perceived exertion will be recorded using a numerical perceived exertion scale after relevant sets or at the end of the session, according to the predefined monitoring protocol. Weekly mean values will be described for each participant.
Measured: Weekly from baseline to week 9
Pace stability during event-specific swimming repetitions
Pace stability will be estimated from repeated swimming times in event-specific distances. The coefficient of variation will be calculated for each participant and distance when repeated measurements are available. Lower values will indicate greater pace stability.
Measured: Repeated training sessions from baseline to week 9
