Kinematic Variables Evolution During a 200-m Maximum Test in Young Paddlers.

Area of Science:

• Sports Science
• Biomechanics
• Human Movement Analysis

Background:

• Understanding kinematic variables in sprint canoeing is crucial for performance optimization.
• Previous research has explored paddling technique, but a detailed analysis of kinematic evolution during a maximal 200m test across different categories is lacking.

Purpose of the Study:

• To analyze the evolution of kinematic variables (speed, cycle frequency, cycle length, cycle index) during a 200m maximal sprint canoe test.
• To compare these kinematic evolutions between young male kayakers, female kayakers, and male canoeists.

Main Methods:

• Fifty-two young paddlers (13-14 years old) performed a 200m maximal sprint test.
• Kinematic variables were recorded every 50m using boat-based measurements.
• Statistical analysis was performed to identify significant differences between categories and sections.

Main Results:

• Speed and cycle index decreased after the initial 50m in all categories.
• Cycle length remained relatively stable, with lower values in the first section.
• Cycle frequency progressively decreased throughout the 200m distance.
• Male kayakers generally exhibited higher kinematic values than female kayakers and male canoeists, with significant differences in speed, cycle length, and cycle index.

Conclusions:

• Kinematic patterns in sprint canoeing show a decline in speed and cycle index after the first 50m.
• Significant differences exist in kinematic variables between male kayakers, female kayakers, and male canoeists.
• Analysis of kinematic variable evolution provides valuable insights for training program design and competition strategy in sprint canoeing.
