RT-japan (Headquarters: Tokyo), led by London Olympic swimming medalist Ryo Tateishi, today launched a "Genetic Testing Support Service" that visualizes individual physical characteristics from approximately 400 genetic items and derives scientifically-based sports and training plans. This is an accompanying, self-explanatory service designed to help individuals make informed choices about "what to do and how to exert effort to achieve results."
1. Background: Why is a "redefinition of effort" necessary?
In Japanese sports, coaching that emphasizes "quantity" and "guts" still deeply persists. However, in its shadow, mismatches such as "not getting results despite practicing harder than anyone else," "injuries due to overtraining," and "recovery not keeping up with age" are repeatedly occurring.
These are not due to a lack of effort, but rather a "mismatch between physical characteristics and the direction of effort." RT-japan democratizes the "dialogue with one's own body" honed by top athletes, making it available as scientific data that anyone can utilize.
2. Features: "Four Selves" revealed by approximately 400 items of analysis
Through the largest-scale and most precise analysis in Japan, covering approximately 400 items, concrete action plans are derived from an unchanging "blueprint" for the following four categories:
① "The Moving Self": Muscle characteristics and energy strategy
Whether you are a sprinter (explosive type) or a long-distance runner (stamina type). Select the optimal event and load for your type.
② "The Resting Self": Fatigue recovery and maintenance ability
Understand the efficiency of fatigue substance removal and susceptibility to inflammation. Identify "your optimal rest rhythm."
③ "The Protecting Self": Injury risk and physical weaknesses
Pre-emptively understand joint/ligament strength and susceptibility to specific injuries, reinforce weaknesses to prevent withdrawal.
④ "The Regulating Self": Sleep, mental state, and lifestyle habits
Visualize optimal bedtime, concentration duration, and response to specific nutrients to regulate mind and body.
3. An accompanying flow that doesn't end with "results" from analysis
Visualization (Knowing yourself): Issue a detailed report that becomes a lifelong physical asset.
Concretization (Designing): Translate analysis results into "tomorrow's training menu" and "care methods."
Maximization (Continuing): By continuing a plan suited to your characteristics, simultaneously achieve talent blossoming for juniors, personal best updates for adults, and extension of healthy lifespan for seniors.

Representative Comment: Ryo Tateishi
"I believe in effort more than anyone. However, throughout my competitive career, I keenly felt the truth that 'effort that doesn't suit your body leads to stagnation and injury, and eventually robs you of passion.' Genes are not a wall, but a hint to expand possibilities. If I had known such detailed 'peculiarities of my own body' during my active career, I would have enjoyed swimming much more. This service is a 'lifelong self-explanatory guide' that helps users understand their characteristics and continue to grow without overexertion. I want everyone who doesn't give up on their potential to use it."
4. Target Users
Junior Athletes: Athletes and guardians who want to accelerate growth with a scientific approach.
Masters Generation / Enthusiasts: Those who want to efficiently update their personal bests in limited time.
