Effects of Knee Joint Angle on Intramuscular Blood Flow and Muscle Deoxygenation During Fatiguing Isometric Contractions

Scandinavian Journal of Medicine &Science in Sports, Volume 36, Issue 4, April 2026.
ABSTRACT The purpose of this study was to investigate the effect of the knee joint angle on intramuscular blood flow and muscle deoxygenation during fatiguing intermittent isometric knee extensions. Seventeen healthy young male participants (19.6 ± 1.3 years) performed intermittent (5 s contraction, 5 s relaxation) and incremental isometric knee ...

Lower‐Body Muscle Volumes Can Explain Half of the Variance in Sprint Speed Between Collegiate American Football Players

Scandinavian Journal of Medicine &Science in Sports, Volume 36, Issue 4, April 2026.
ABSTRACT Sprinting speed is critical for success across many sports. Lower‐body muscle size is important, but it is difficult to determine which muscles have the greatest influence on speed, and it is unclear how much variance in speed between athletes can be explained by variance in muscle size alone.

Synthetic estrogen and progestin effects on the myogenic program following damage in C2C12 murine myoblasts

Physiological Reports, Volume 14, Issue 8, April 2026.
The effect of oral contraceptives (OCs) on muscle repair is unknown. Using electrical pulse stimulation to simulate damage in C2C12 myoblasts treated with four OC generations (MPA, LNG, DSG, DRP combined with ethinyl estradiol), we assessed proliferation, differentiation, migration, creatine kinase, myogenic proteins, and hormone receptor protein ...
