Jungkook of BTS has garnered attention for sharing his workout certification about a month before the Gwanghwamun concert.
Recently, Jungkook posted a photo of his treadmill record along with a short phrase 'Aja Aja' on his social media. The workout time and distance he certified were 1 hour and 19 minutes and 8.02 km, respectively.
He boasted an average pace of 9 minutes and 50 seconds per km, showcasing his impressive endurance. This demonstrates how much effort Jungkook, evaluated as a 'performance artist', is putting into fitness management for the concert taking place on March 21 in Gwanghwamun.
Average Heart Rate 168 BPM…Maintaining High-Intensity Intervals
Born in 1997, Jungkook is currently 28 years old. The maximum heart rate for a male in his late 20s is estimated to be around 190-195 BPM. The average heart rate of 168 BPM that Jungkook certified is about 85-90% of the maximum heart rate. This indicates that Jungkook is not just walking or lightly jogging, but engaging in high-intensity aerobic (Zone 4) exercise.
High-intensity aerobic exercise rapidly improves cardiovascular endurance. In other words, it means that he has the stamina to handle intense choreography and live performances during a concert that lasts 2-3 hours. This is why there are analyses suggesting that Jungkook's workout records are close to 'athlete-level conditioning'.
Altitude 690m…Strengthening Lower Body Endurance with 'Incline Running'
The altitude of 690m is also notable. This indicates that Jungkook set the treadmill incline quite high. Running on an incline strengthens the endurance of the glute muscles, hamstrings, and calves.
Jumping movements on stage, quick direction changes, and powerful choreography require strong lower body endurance. Incline running is effective for building the stamina needed to generate explosive energy.
The calories burned also reach 900 kcal. Such high-intensity aerobic exercise that burns a lot of calories is good for managing body fat and maintaining abdominal lines. It also helps improve insulin sensitivity.
Athlete-Level Fitness Management…Recovery After Exercise is Essential
Jungkook's workout records are interpreted as fitness management in preparation for the concert rather than just for weight loss. Idol concerts are essentially close to high-intensity interval training. This is because he needs to maintain a high heart rate while repeating singing and choreography. The fact that he maintained an average heart rate of 168 BPM for over an hour already shows that he has a significant cardiovascular base.
However, repeating high-intensity exercise can increase cortisol, the stress hormone, and lead to fatigue. It is necessary to combine sufficient sleep, protein intake, and low-intensity recovery exercises after high-intensity training.
