Ryusei Yonee Sets a New World Record: 100 Meters on All Fours in 14.55 Seconds

In an extraordinary feat of human capability, Japanese athlete Ryusei Yonee has sprinted 100 meters on all fours in just 14.55 seconds, earning a new Guinness World Record that captures the imagination. This impressive achievement not only highlights Yonee’s athletic prowess but also opens a conversation about the potential of animal-inspired movement and the power of innovative training techniques.

The Big Takeaway

At just 22 years old, Yonee’s record-breaking time of 14.55 seconds not only surpasses the previous record set by Collin McClure at 15.66 seconds in 2022, but marks a significant improvement from Kenichi Ito’s initial 2008 record of 18.58 seconds. This advancement across nearly two decades emphasizes the ongoing evolution of athletic performance when ideal conditions, training techniques, and support systems converge.

A Progression of Records

Training Insights from Yonee

Yonee’s journey began with a fascination for how animals move. He studied various quadrupeds—dogs, cats, and monkeys—to understand the biomechanics of their movements. Through careful observation, he learned about limb timing and body angles, which significantly influenced his training routine.

In preparation for his record-setting day, Yonee primarily trained on sandy surfaces. “The sand provided a different challenge and required a lot of control,” he commented, but he later transitioned to a track to adapt his technique to leverage the unique rebound characteristics it provided. This transition altered his force return, leading to further refinements in his form.

Crawling: A Key Component of Smart Training

While many may think of crawling as child’s play, it presents a myriad of benefits for athletes of all levels. Quadrupedal movements enhance shoulder health, core stability, and overall conditioning without the high impact associated with traditional running.

Benefits of Crawling in Strength Training

• Improves scapular control and shoulder health.
• Integrates core stability across multiple planes.
• Strengthens hips and glutes without excessive loading.
• Offers a low-impact conditioning stimulus.
• Enhances the timing and coordination needed for athletic movements.

Just as Yonee demonstrated through his achievement, including crawling patterns in training can yield substantial benefits for both everyday athletes and those aiming to break records.

Safety Considerations: Risks and Modifications

Before diving into crawling movements, it’s crucial to consider potential risks. The wrists, elbows, and shoulders endure considerable load during these exercises. Additionally, improper posture or fatigue may strain the lower back and knees, making a knowledge of safety paramount.

Who Should Exercise Caution?

• Individuals with prior wrist pain, carpal tunnel syndrome, or upper limb injuries.
• Those with existing shoulder conditions or instability.
• People dealing with knee pain or other acute conditions.
• Pregnant women or those recently postpartum should consult a healthcare provider.

It’s advisable to stop any activity at the first sign of sharp pain, ensuring that injuries don’t escalate.

Getting Started with Crawling: Progressions for Beginners

For those interested in incorporating crawling into their fitness regime, beginning with controlled movements is essential. Here’s a simple warm-up and technique guide to lay the groundwork:

Warm-Up in 6 Minutes

1. Wrist prep: flexion/extension rocks, 10 each direction.
2. Scapular push-ups: 10 controlled reps.
3. Cat-cow to thread-the-needle: 5 per side.
4. Hip hinge to bear hold transitions: 3 rounds of 20 seconds holds.

Technique Tips for Crawling

• Maintain a neutral spine with ribs stacked over the pelvis.
• Position hands under the shoulders and knees under the hips.
• Engage the floor to enhance shoulder stability.
• Focus on short steps with opposite hand and foot movement.
• Prioritize quiet steps and steady breathing throughout.

Four-Week Beginner Plan

A four-week plan can guide novices through safe progression:

• Week 1: Bear crawl 5 x 10 meters at an easy pace with 60–90 seconds rest.
• Week 2: Leopard crawl 6 x 10 meters at a moderate pace with 60 seconds rest.
• Week 3: Forward and backward bear crawl 4 x 12 meters each with 75 seconds rest.
• Week 4: Timed sets, 6 x 20 seconds work, with 70–90 seconds rest focusing on rhythm.

Progressions and Regressions

• Easier: Use elevated hands on a box to ease pressure on joints.
• Easier: Practice static bear holds for added stability.
• Harder: Introduce lateral crawls or uphill segments.
• Harder: Experiment with tempo intervals for rhythm training.

Surface, Gear, and Recovery

Choosing the right surface for crawling can greatly influence performance. Soft surfaces like turf and rubber tracks minimize skin abrasions while enhancing traction.

• Using thin training gloves can provide utility without losing tactile feedback.
• Knee sleeves or longer tights protect against scrapes during practice.
• Post-training care, including forearm stretches and gentle tissue work, helps maintain joint health.

Frequently Asked Questions

Does Crawling Improve Running Speed?

Yes! The contralateral movements that occur during crawling translate well into improved timing and coordinated movement patterns during running.

How Effective is Crawling for Conditioning?

Crawling engages multiple muscle groups, leading to a quick increase in heart rate and effective body conditioning, all while maintaining a low impact profile.

How Often Should You Train?

For beginners, two sessions per week is advisable, gradually increasing frequency as your body adapts to the movements.

Mindset and Motivation from Ryusei Yonee

Throughout his journey, Yonee has remained steadfast that community support is vital. He believes that competitive sports extend beyond just the athletes; they engage everyone involved. “I want to train harder than ever before. I aim to grow the all-four sports, wherever that may be,” he expressed, hinting at future ambitions that extend beyond his current record.

Key Lessons to Apply

• Begin with basic bear holds and short crawls.
• Select surfaces that align with your training goals.
• Keep overall distance short initially and gradually introduce more volume.
• Always prioritize good form and stop if any pain is felt.
• Supplement crawling with additional strength exercises for a balanced workout.
