© 2020 The Authors. Scandinavian Journal of Medicine & Science In Sports published by John Wiley & Sons Ltd This study tested the hypothesis that the magnitude of rectus femoris (RF) damage and the repeated bout effect (RBE) would be greater after knee extensor eccentric exercise performed in a supine (long RF lengths) than a sitting (short RF lengths) position, and the muscle length effects would be more prominent at the proximal than distal RF. Young untrained men were placed to one of the two groups (n = 14 per group). S group performed the knee extensor eccentric exercise in …


Changes In The Number Of Circulating Cd34+ Cells After Eccentric Exercise Of The Elbow Flexors In Relation To Muscle Damage, Ho Seong Lee, Makii Muthalib, Takayuki Akimoto, Kazunori Nosaka Sep 2015

Changes In The Number Of Circulating Cd34+ Cells After Eccentric Exercise Of The Elbow Flexors In Relation To Muscle Damage, Ho Seong Lee, Makii Muthalib, Takayuki Akimoto, Kazunori Nosaka

Research outputs 2014 to 2021

Background: It has been reported that strenuous exercise increases the number of bone marrow-derived progenitor cells such as CD34+ cells in the blood, but no previous studies have investigated the changes in circulating CD34+ cells following resistance exercise. This study tested the hypothesis that the number of CD34+ cells in the blood would increase after eccentric exercise of the elbow flexors, but decrease in recovery, and the magnitude of the changes would be dependent on the magnitude of muscle damage.

Methods: Nine men (28.0 ± 6.6 years) performed exercises consisting of 10 sets of six maximal voluntary …
