[Academic journal article introduction] The optimal way to consume protein and amino acids for building the bodies of athletes (Food and Medicine No. 20)
2022.02.18

In the January 1st issue of Food and Medicine (edited by Kodansha Editorial), issue 31, in a special feature titled "Sports and Nutrition," Kato of the Sports Nutrition Department at Ajinomoto Co., Inc. contributed an article on "The optimal method of protein and amino acid intake for athletes to build their bodies."
[Paper introduction] Effects of cystine and glutamine intake on exercise-induced changes in gastrointestinal permeability and injury markers in young men
2022.02.18

Objective: It has been reported that prolonged, high-intensity exercise increases permeability and injury markers, which are indicators of impaired gastrointestinal function, but little has been reported about the intervention effects of nutritional supplements on exercise-induced gastrointestinal disorders. In this study,...
[Conference/Seminar Report] Announcement at the 76th Japan Society of Physical Fitness and Sports Medicine that "6 Amino Acid Mix" improves joint discomfort and pain
2021.11.17

At the 76th Japanese Society of Physical Fitness and Sports Medicine (September 2021-9, 17), Ajinomoto Co. Food Research Institute announced that its proprietary amino acid ingredient "19 Amino Acid Mix for Joint and Tendon Conditioning" improves joint discomfort and function. Joints are the joints that connect bones together...
[Conference/Seminar Report] Announcement at the 68th American College of Sports Medicine that "6 Amino Acid Mix" improves Achilles tendon condition
2021.11.17

Professor Yasuo Kawakami of the Graduate School of Sport Sciences at Waseda University presented a presentation at the 68th American College of Sports Medicine (June 2021-6, 1) on the efficacy of Ajinomoto Co.'s proprietary 5 Amino Acid Mix for Joint and Tendon Conditioning in improving the uniformity and stiffness of the Achilles tendon structure...
[Academic conference/seminar report] Evidence presented on the "6-amino acid mix for joint and tendon conditioning" that supported the Japanese national team at a media seminar hosted by Ajinomoto Co., Inc.
2021.11.05

On September 2021, 9, Ajinomoto Co., Inc. held a media seminar titled "Sports Nutrition and Amino Acids" - From our efforts to support top athletes. In addition to lectures on Ajinomoto Co., Inc.'s support for athletes, athletes' real-life experiences, and the importance of sports nutrition, the seminar also featured the company's unique blend of amino acids...
[Academic conference/seminar report] Two effects of cystine were presented at the 6th Industry-Government-Academia Collaboration Symposium hosted by the Japanese Society of Amino Acid Science
2021.07.19

The Ajinomoto Food Research Institute reported on two effects of cystine at the 6th Industry-Government-Academia Collaboration Symposium hosted by the Japanese Society of Amino Acids (held online on May 2021, 5). Cystine is a combination of two molecules of cysteine, a non-essential amino acid. This...
[Paper introduction] Cystine attenuates oxidative stress-induced tight junction permeability and intestinal inflammation in Caco-2 cells
2021.07.06

Oxidative stress in the intestine produces proinflammatory cytokines and increases tight junction (TJ) permeability, leading to intestinal and systemic inflammation. Cystine is a substrate for glutathione and inhibits inflammation, but it is unclear whether cystine locally improves intestinal barrier dysfunction. ...
[Paper introduction] The effect of essential amino acids with high leucine content on muscle recovery
2021.07.06

[Objective] This study was conducted to verify whether the intake of leucine-rich essential amino acid (LEAA), which is known to increase muscle protein synthesis, reduces muscle damage and promotes recovery by improving muscle damage. [Subjects and Methods] Dual...
[Paper introduction] Essential amino acids rich in leucine improve recovery from muscle damage after exercise in young men independently of muscle protein synthesis
2021.07.06

Leucine-rich essential amino acids (LEAA) rapidly increase muscle fiber protein synthesis after exercise, which is important for muscle repair and recovery. However, no studies have been conducted in the general population to show that LEAA simultaneously increases muscle fiber protein synthesis and recovery from muscle injury.
[Paper introduction] Effects of leucine-rich essential amino acids on anabolism and catabolism in human skeletal muscle after resistance exercise
2021.07.06

Resistance exercise transiently activates the anabolic and catabolic systems of skeletal muscle. Leucine-rich essential amino acids (LEAAs) have been reported to stimulate the muscle anabolic system at lower doses than whey protein. However, resistance exercise-induced…
