Is the health condition of junior sumo players okay?Research compared to obese children Tsukuba University, etc.

Junior sumo players are obese, but are you worried about your health?Many people will have such questions vaguely.One of the answers to one of the questions was reported.A paper was published in "Physical Activity and Nutrition" by Miori Ogawa and others from the University of Tsukuba Internal Medicine Sports Medicine Laboratory.

Comparison in 3 groups of obese children who are playing sports other than junior sumo and sumo wrestling

Obesity is not good for your health.Not surprisingly, sumo wrestling is a more advantageous sport with a larger physique.The heavier one is less likely to be pushed out of the ring, and subcutaneous fat suppresses the risk of injuries during the work.

The sumo wrestlers, the wrestlers, are obese, but they have a lot of physical activity, not only fat but also muscles.For this reason, wrestlers obesity is sometimes referred to as "healthy obesity", but it is reported that metabolic indicators are often exceeded the standard value.However, reports on the health status of junior sumo players are limited.Ogawa and his colleagues focused on this point and conducted this research.

The research method is to compare junior sumo players, obese children who are doing sports other than sumo, and obesity compositions and metabolic indicators without exercise habits.All research participants are boys, and 14 people from 9-17 years old for junior sumo clubs are recruited from the Sumo Club, and their years of sumo have experience 4..7 ± 1 year.The latter two are 56 patients aged 9 to 14 years old who are visiting a pediatric obesity outpatient.In addition, the second part of the two poses simple obesity as a qualified condition, excluding secondary obesity patients derived from specific diseases and pathology such as central nervous system and endocrine systems.

The ages of each group were 14 ± 2 years old, while sports and non -motor groups other than sumo were 11 ± 1 year old, significantly lower than the sumo players.

Junior sumo players may need to pay attention to blood pressure and good cholesterol low

Looking at the results, the height and weight of the sumo players were significantly higher than the other two groups.BMI and BMI Z score are 33 Sumo players.2 ± 5.8 (2).3 ± 0.6) Sports groups other than sumo 27.5 ± 4.0 (2).0 ± 0.3), Non -athletic group 29.6 ± 6.1 (2).1 ± 0.4), and sports other than sumo wrestling were significantly lower than the other two groups.The waist height ratio is 0 in order.60 ± 0.07, 0.60 ± 0.04, 0.66 ± 0.It was 09, and the non -motor group was significantly higher than the other two groups.

The obesity calculated by [Weight -Ideal weight (value based on school health statistics) / ideal weight x 100] is 68 in the same order.2 ± 23.5 %, 49.7 ± 18.1 %, 61.1 ± 26.It was 3 %, and there was a significant difference between the sumo players and the sports groups other than the sumo wrestling.

Next, when comparing the blood pressure level by adjusting the age, the blood pressure is 132 ± 12 mmhg, a sport group other than sumo wrestling, 117 ± 11 mmHg, and a non -motor group 123 ± 11 mmHg, and the sumo players are not sumo players.It was significantly higher than the sports group.In the same order, the expansion of blood pressure (age not adjusted) was 69 ± 6 mmHg, 63 ± 8 mmHg, 68 ± 17 mmHg, and there was no significant difference between the groups.

Looking at the metabolic indicators, there was no significant difference between LDL-C (bad cholesterol), non-HDL-C (non-good cholesterol), TG (neutral fat), blood sugar level, and HBA1C.Regarding HDL-C (good cholesterol), sumo players are 45 ± 5 mg/dl, sports other than sumo wrestling, 55 ± 15 mg/dl, non-exercise group 50 ± 12 mg/dl, and sumo players are not sumo groups.There was a lower and significant difference.

Compared to the average measurement value of each group, compared to the reference value, the average value is a reference value (LDL-C140mg/LDL-C140mg/LDL-C140mg/LDL-C140mg/LDL-C140mg/LDL-C/HDL-C compared to the standard value.Less than DL, less than Non-HDL-C150mg/DL).

However, with regard to TG, sports and non -exercise groups other than sumo wrestling exceeded the standard value (less than 120 mg/dl).On the other hand, the average of TG was lower than the standard value in the sumo players.However, the HDL-C, which is often inverted with TG, was lower than the other two groups (the average value is within the total group standard value, including the sumo players as described above.40mg/dl or more>

Regarding blood sugar levels, only sumo players were below the reference value (less than 100 mg/dl).However, HBA1C is within the total group (6).Less than 5 %), and the upper limit of the 95 % confidence section is 6.It was less than 5 %.

Need for preventive intervention such as dietary habits for junior sumo players

Based on the above results, Watanabe Laboratory has added detailed consideration about the health of junior sumo players along with the knowledge of the previous research.To introduce a part of it, first of all, the sumo players have a large physique and the size of the physique increases through an increase in circulating plasma even after age adjustment.In addition to contributing to, it is involved in the mechanisms such as insulin resistance associated with obesity and enhancement of the sympathetic nervous system.Junior sumo wrestling has said that there is a risk of hypertension, and hypertension of pediatric hypertension is likely to shift in adults, so it is necessary to intervene in eating habits.

Next, the point that the average HDL-C is within the standard value, but significantly lower than the other two groups, in the case of adult wrestlers aged 20 and over, HDL increased.According to the report that -C will decrease, the risk of future atherosclerosis is suggested.

On the other hand, regarding blood sugar levels, the average value of the sumo players was within the reference value, and continuous exercise increased muscle mass and increased expression of glut4 (glucose transporter Type 4), causing skeletal muscle.It is speculated that the sugar removal in this may be contributed to the increase in blood sugar levels.

The conclusion is, "Junior sumo players had a larger physique and blood pressure than obese children even after age adjustment. This knowledge needs to consider the need to examine the preventive intervention in the junior sumo player for metabolic syndrome and its direction.It can be said that it is indicated. "
