Heart Rate Behavior in Speed Climbing

Area of Science:

• Sports Science
• Exercise Physiology
• Climbing Biomechanics

Background:

• Speed climbing debuted as an Olympic discipline in 2020, demanding high-speed, anaerobic exertion under extreme psychological pressure.
• While heart rate (HR) data exists for lead climbing, the physiological responses during speed climbing remain under-researched.
• Understanding HR behavior is crucial for optimizing training and competition strategies in this demanding sport.

Purpose of the Study:

• To investigate the heart rate (HR) behavior of near-elite athletes during speed climbing.
• To analyze HR acceleration and deceleration patterns in response to climbing stimuli.
• To evaluate the adequacy of current rest intervals for HR recovery in speed climbing competitions.

Main Methods:

• Seven near-elite speed climbers' HR was monitored using a Polar HR monitor.
• Participants completed three climbs each on 10-m and 15-m walls with standardized rest periods.
• Climbing times, peak HR, HR acceleration/deceleration rates, and HR during recovery were recorded and analyzed.

Main Results:

• Average climbing times were 9.16s (10m) and 14.95s (15m).
• Peak HR reached 164.57 bpm (10m) and 176.43 bpm (15m).
• Trained athletes exhibited significantly lower HR acceleration (2.53 bpm/s) compared to untrained individuals in less stressful activities, and HR recovery was adequate within 5-minute intervals.

Conclusions:

• Near-elite speed climbers demonstrate efficient HR regulation, characterized by lower HR acceleration under high-pressure conditions.
• The observed HR patterns suggest that athletes trained for high physical and psychological demands exhibit distinct physiological responses.
• The standard 5-minute rest period between attempts in speed climbing competitions appears sufficient for adequate HR recovery.
