Cardiorespiratory response to bicycle and rowing ergometer exercise in oarsmen

Area of Science:

• Sports Science
• Exercise Physiology
• Human Performance

Background:

• Assessing maximal aerobic power is crucial for understanding athletic capabilities.
• Different ergometers may yield varying physiological responses.
• Training specificity suggests adaptations are specific to the type of exercise performed.

Purpose of the Study:

• To compare maximal aerobic power and related physiological variables between rowing and bicycle ergometers.
• To investigate the influence of training specificity on exercise responses in oarsmen versus untrained individuals.

Main Methods:

• Maximal aerobic power and submaximal work variables were measured in 9 oarsmen and 9 control subjects.
• Exercise protocols were conducted on both a rowing ergometer and a bicycle ergometer.
• Key variables included heart rate, pulmonary ventilation, oxygen uptake, and oxygen pulse.

Main Results:

• Oxygen uptake at submaximal workloads was higher on the rowing ergometer for both groups.
• Untrained subjects showed significantly lower maximal oxygen uptake and oxygen pulse on the rowing ergometer compared to the bicycle ergometer.
• Oarsmen demonstrated comparable maximal values on both ergometers, indicating high test-retest reliability and specificity of training.

Conclusions:

• The findings support the principle of training specificity in exercise physiology.
• Oarsmen's adaptations to rowing training result in similar maximal aerobic capacity regardless of the ergometer used.
• Untrained individuals show ergometer-dependent differences in maximal aerobic power assessment.
