In a groundbreaking study published in the *Journal of Engineered Fibers and Fabrics* (translated as the Journal of Engineered Fibers and Textiles), researchers have developed a novel approach to designing functional leggings tailored for late middle-aged women, leveraging 3D technology and electromyography (EMG) to optimize muscle support. Led by Nam Yim Kim from Kongju National University in the Republic of Korea, the research identifies the optimal pressure levels needed to support key thigh muscles, potentially revolutionizing the activewear industry and offering significant benefits for women in their 50s.
The study focuses on the vastus medialis and vastus lateralis muscles within the quadriceps femoris, which are crucial for maintaining knee stability and overall leg strength. Using 3D human body data, the team created functional leggings with targeted reinforcement in these areas. “We aimed to develop leggings that not only provide comfort but also offer substantial muscle support,” Kim explained. “By analyzing muscle fatigue responses through surface EMG, we were able to pinpoint the exact pressure levels needed to enhance muscle performance and reduce fatigue.”
The leggings were designed with region-specific reduction rates derived from preliminary evaluations and virtual simulations. Quantitative clothing pressure measurements revealed that the pressure was lowest at the waist (0.77 kPa) and highest at the back of the calf (1.98 kPa). This precise pressure distribution ensures optimal muscle support without compromising comfort.
One of the most significant findings was the reduction in muscle fatigue. When wearing the leggings, participants experienced a notable decrease in fatigue in the vastus medialis and vastus lateralis compared to loose-fit control pants. “The reductions exceeded 20% in the vastus medialis and biceps femoris, which is a remarkable achievement,” Kim noted. “This indicates that our leggings can effectively support muscle activity and reduce fatigue during physical activities.”
Subjective evaluations further highlighted the leggings’ effectiveness. Participants reported high satisfaction across all items, particularly in muscle support and suitability for exercise. “The feedback from our participants was overwhelmingly positive,” Kim said. “They felt more supported and comfortable, which is crucial for maintaining an active lifestyle.”
The implications of this research extend beyond the activewear industry. As the population ages, there is a growing demand for clothing that supports muscle health and reduces the risk of injuries. The development of these functional leggings could pave the way for similar innovations in other types of clothing, offering tailored support for various muscle groups.
Moreover, the use of 3D technology and EMG analysis in garment design represents a significant advancement in the field. This approach allows for precise customization, ensuring that each piece of clothing is optimized for the wearer’s specific needs. “Our method can be applied to other types of clothing, providing personalized support for different muscle groups,” Kim explained. “This could lead to a new era of functional apparel that enhances muscle performance and reduces fatigue.”
In conclusion, the research led by Nam Yim Kim from Kongju National University offers a promising solution for late middle-aged women seeking comfortable and supportive activewear. By combining 3D technology with EMG analysis, the team has developed leggings that not only reduce muscle fatigue but also enhance overall comfort and satisfaction. This innovative approach has the potential to revolutionize the activewear industry and pave the way for future developments in functional apparel.
