[Miyazaki (Japan) = Sports Chosun Reporter Han Dong-hoon] Doosan Bears pitchers ran 's sandbag' in the closing camp. Intensity was increased to extract maximum effect for a limited time.

Coach Kim Won-hyung called for intensive training during the final training session. Not only the fielders but also the pitchers increased the amount of training.

Doosan Training Part produced a 15kg dirt bag on the 10th. Head coach Kim Won-hyung emphasized running, and the idea was devised by the training part to maximize the effect.




The players kicked it around the waist. The 50-meter sprint was repeated more than five times. The athletes who needed more running ran the 100m round trip.

Only pitchers who are caught live pitching on the day are enthusiastic. High-intensity running was conducted every four days.

The training part explained that it is a way to increase concentration in a short period of time. The training part " has an excellent effect on instantaneous speed and strengthening power throughout the body. It is a similar concept to running with tires in the past. If you wear a dirt bag and run 50m, you are definitely slow. If you get used to being strong when you first start, you can also feel light when you run with your bare body.

Players also felt the effects with their skin. As for Jehwanyu "15kg of resistance was added, he definitely used his lower body more, and as he took his stride forward significantly, he felt a new stimulus. It was hard. This is the first training session since running with tires in elementary school. As I ran, I got used to it little by little, and after that, I felt faster and lighter when I ran with my bare body" expressed satisfaction.

Lee Ju-yeop also said "My body was too heavy, and my back was not straightened well after running " and felt that my lower body became firm. I think it's working. I will continue to focus on strengthening my lower body during the rest of the final camp,' he vowed.
