The Acute and Prolonged Effects of Different Durations of Foam Rolling on Range of Motion, Muscle Stiffness, and Muscle Strength.
Masatoshi Nakamura,Remi Onuma,Ryosuke Kiyono,Koki Yasaka,Shigeru Sato,Kaoru Yahata,Taizan Fukaya,Andreas Konrad +7 more
TL;DR: In this paper, the authors investigated the acute and prolonged effect of different durations of foam rolling intervention on ROM, muscle stiffness, and muscle strength, and they found that foam rolling for more than 90 s or more was effective in order to increase the range of motion immediately without changing muscle stiffness.
Journal ArticleDOI
The Acute Effect of Foam Rolling on Eccentrically-Induced Muscle Damage
Masatoshi Nakamura,Koki Yasaka,Ryosuke Kiyono,Remi Onuma,Kaoru Yahata,Shigeru Sato,Andreas Konrad +6 more
TL;DR: In this article, the authors investigated the effect of short-term duration foam rolling intervention on an eccentrically-damaged muscle in the leg extensors and detected the acute effect of 90s foam rolling on muscle soreness and muscle function of the quadriceps muscle.
Journal ArticleDOI
Effects of Static Stretching With High-Intensity and Short-Duration or Low-Intensity and Long-Duration on Range of Motion and Muscle Stiffness
Taizan Fukaya,Ryosuke Kiyono,Shigeru Sato,Kaoru Yahata,Koki Yasaka,Remi Onuma,Masatoshi Nakamura +6 more
TL;DR: The results suggest that a higher intensity of the static stretching should be conducted to increase ROM and decrease muscle stiffness, even for a short time.
Journal ArticleDOI
Effects of 5-Week Foam Rolling Intervention on Range of Motion and Muscle Stiffness.
TL;DR: The results suggested that FR was an effective method to increase DFROM given its ability to change passive torque at D FROM (stretch tolerance) without altering muscle stiffness.
Journal ArticleDOI
Local and Non-local Effects of Foam Rolling on Passive Soft Tissue Properties and Spinal Excitability
Masatoshi Nakamura,Andreas Konrad,Ryosuke Kiyono,Shigeru Sato,Kaoru Yahata,Riku Yoshida,Koki Yasaka,Yuta Murakami,Futaba Sanuki,Jan Wilke +9 more
TL;DR: In this paper, the authors examined the effect of roller massages on the plantar flexors in the treated (ROLL) and non-treated (NO-ROLL).
