Description

락토바실러스 플란타럼 HY7715를 포함하는 근육질환 예방 또는 개선용 조성물{Composition for Preventing or Aemliorating Muscular Diseases Comprising Lactobacillus Plantarum HY7715}Composition for preventing or improving muscle disease comprising Lactobacillus plantarum HY7715 {Composition for Preventing or Aemliorating Muscular Diseases Comprising Lactobacillus Plantarum HY7715}

본 발명은 락토바실러스 플란타럼 HY7715를 포함하는 근육질환 예방 또는 개선용 조성물에 관한 것이다.The present invention relates to a composition for preventing or improving muscle disease comprising Lactobacillus plantarum HY7715.

한국인의 기대수명은 경제 성장과 함께 다른 나라 대비 빠르게 증가하였다. 1960년 52.4세에 불과했던 기대수명이 1990년에는 71.4세, 2016년에는 82.4세로 증가하였다. 하지만 건강수명은 2016년 평균 64.9세로, 생애 마지막 17.5년은 건강 문제로 활동에 제약을 받으며 산다.Life expectancy of Koreans increased faster than other countries along with economic growth. Life expectancy increased from 52.4 years in 1960 to 71.4 years in 1990 and 82.4 years in 2016. However, the average healthy life expectancy in 2016 was 64.9 years, and the last 17.5 years of life are limited by health problems.

기대수명 대비 건강수명이 낮은 이유 중 한가지는 근육이다. 한국인은 시대 발전에 따라 기대 수명이 연장되었으나, 운동량이 적고, 노화로 인해 노년기에 접어들수록 급격히 근육의 양이 감소한다. 일반적으로 50세 이후 근육은 매년 1~2% 감소하고, 10년이면 평균 4kg 정도 감소하는 것으로 알려져 있다. 또한, 65세엔 중년 때 근육의 평균 약 25~35% 정도가 감소하고, 80세엔 40%이상 감소하면서 기력이 떨어진다. 나이가 들면서 겪게 되는 근감소증은 단순히 근력이 감소하는 것을 넘어 면역력을 저하시키며, 고지혈증, 당뇨, 관절질환 등 각종 질환 발병률을 높인다.One of the reasons for the low health life expectancy compared to life expectancy is muscle. The life expectancy of Koreans has been extended according to the development of the times, but the amount of exercise is low and the amount of muscle rapidly decreases as they enter old age due to aging. In general, it is known that after the age of 50, muscle decreases by 1 to 2% every year, and an average of 4 kg in 10 years. In addition, at the age of 65, an average of about 25-35% of the muscle in middle age decreases, and at the age of 80, the energy decreases by more than 40%. Sarcopenia experienced with aging not only decreases muscle strength, but also lowers immunity and increases the incidence of various diseases such as hyperlipidemia, diabetes, and joint diseases.

따라서 앞으로 더 심해질 고령화 시대에 노화로 인해 줄어드는 근육이 감소하는 것을 억제해주거나, 개선할 수 있는 프로바이오틱스, 음료, 건강식품과 같은 제품 개발이 필요하다. Therefore, it is necessary to develop products such as probiotics, beverages, and health foods that can suppress or improve muscle loss due to aging in the aging population, which will become more severe in the future.
