A volleyball player completes an aerobic continuous training session by riding a stationary bike at a constant pace for 50 minutes at 65% of maximum heart rate.

What is the primary energy system being targeted by this type of training?

  1. ATP-PC system
  2. Lactic acid system
  3. Aerobic energy system
  4. All energy systems equally

Consider Option C: Aerobic energy system

  • Aerobic continuous training at moderate intensity (65% MHR) for an extended duration (50 minutes) primarily targets the aerobic energy system.

Other Options:

  • A is incorrect: ATP-PC system is anaerobic and only supplies energy for 10-15 seconds of high-intensity activity.
  • B is incorrect: Lactic acid system is anaerobic and provides energy for approximately 30 seconds to 2 minutes of high-intensity activity.
  • D is incorrect: While all energy systems operate simultaneously, this training specifically targets aerobic energy system development.
