Effects of Training Sets Sequence on Swimming Performance, Training Load and Physiological Responses

Area of Science:

• Sports Science
• Exercise Physiology
• Swimming Performance

Background:

• Understanding the impact of training set sequencing is crucial for optimizing swim performance.
• Previous research has not fully explored the specific effects of sprint, lactate threshold, and maximal aerobic speed set order.

Purpose of the Study:

• To investigate how the sequence of different training sets affects physiological responses in male swimmers.
• To determine if set order influences performance metrics and biochemical markers during a training session.

Main Methods:

• Twelve male swimmers completed four randomized training sessions, each with a unique set sequence (A-C, C-A, B-C, C-B).
• Sets included lactate threshold (Set A), maximal aerobic speed (Set B), and sprint intervals (Set C).
• Measurements included speed, blood lactate, pH, base excess, bicarbonate, and heart rate variability (HRV).

Main Results:

• Swimming speed remained consistent across all set sequences.
• Physiological responses during lactate threshold and sprint sets were unaffected by order.
• Maximal aerobic speed sets showed increased metabolic disturbance and decreased HRV when performed after sprint sets.
• Overall session biochemical disturbance was greater when sprint sets preceded other sets.

Conclusions:

• The sequence of swim training sets significantly influences physiological strain, particularly for maximal aerobic speed sets.
• Sprint interval sets preceding maximal aerobic speed sets heighten metabolic and autonomic nervous system responses.
• Coaches should consider set sequencing to manage training intensity and physiological load effectively.
