Eccentric contraction‐induced quadriceps strains, particularly in the rectus femoris (RF),
frequently occur in sports. By using MRI‐based transverse relaxation time (T2) as an index …

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 …

Contracting the knee flexor muscles immediately before a maximum voluntary contraction
(MVC) of knee extension increases the maximal force that the extensor muscles can exert. It …

Both the repeated-bout effect and increased flexibility have been linked to reduced muscle
damage, fatigue, and strength loss after intense eccentric exercise. Our purpose was to …

Background: Thigh muscle atrophy is a major impairment that occurs early after
reconstruction of the anterior cruciate ligament and persists for several years. Eccentric …

Purpose This study aimed to examine whether muscle activation of the quadriceps femoris
differs between single-and multi-joint exercises, and to explore the factors resulting in …

This study aimed to verify the time course recovery of muscle edema within the quadriceps
femoris and functional performance after lower-body single-and multi-joint exercises. For …

Repeated bout effect (RBE) describes a phenomenon that an initial unaccustomed eccentric
exercise (ECC) bout can confer a protective effect against muscle damage from the …

This study examined localization of muscle damage within the quadriceps femoris induced
by different types of eccentric exercises by using transverse relaxation time (T2)‐weighted …

Background: Novel interventions that can safely and effectively overload muscle early
following anterior cruciate ligament reconstruction are needed to minimize atrophy and …
