Physiological Responses to Increasing Battling Rope Weight During Two 3-Week High-Intensity Interval Training...

Area of Science:

• Exercise Physiology
• Sports Science
• Human Performance

Background:

• High-intensity interval training (HIIT) is effective for improving cardiorespiratory fitness and muscular adaptations.
• Battling ropes offer a unique modality for HIIT, engaging the upper body and core.
• The impact of progressive overload, specifically increasing resistance, within battling rope HIIT is not well-established.

Purpose of the Study:

• To investigate the physiological effects of increasing battling rope weight during a 6-week HIIT program.
• To assess changes in upper-body oxygen consumption, muscle strength, power, and endurance performance.
• To determine if progressive increases in battling rope resistance enhance training adaptations.

Main Methods:

• Eighteen men and 15 women participated in 6 weeks of battling rope HIIT, 3 times per week.
• Participants performed 10 bouts of 30-second all-out battling rope exercises with 60-second rest intervals.
• Rope weight was increased by 10 lbs after the initial 3-week period, maintaining high intensity (≥85% max heart rate).

Main Results:

• Significant improvements in upper-body maximal oxygen consumption (V̇o2max) were observed after 3 and 6 weeks.
• Skeletal muscle strength, power, and endurance (shoulder flexion/extension, push-ups, sit-ups) increased significantly.
• Progressive increases in battling rope weight correlated with further enhancements in performance metrics.

Conclusions:

• Battling rope HIIT effectively improves cardiorespiratory fitness and skeletal muscle performance.
• Adaptations occur within 3 weeks, with continued improvements observed with increased workloads over 6 weeks.
• This training modality can be progressively overloaded to enhance physiological adaptations.
