Final answer:
For transportation workouts on a rowing machine, a stroke rate of 24-30 strokes per minute is recommended to sustain a strong, aerobic pace while maintaining good form.
Step-by-step explanation:
When considering a stroke rate for transportation workouts on a rowing machine, it's important to balance intensity and sustainability. For continuous, longer workouts that are meant to build endurance and mimic on-water distance rowing, a stroke rate of B) 24-30 strokes per minute is often recommended. This rate allows individuals to maintain a strong, aerobic pace without becoming anaerobic, which can happen at higher stroke rates and might not be sustainable for longer periods. It's essential to maintain good form at this stroke rate to ensure efficiency and prevent injury.
