1.
Schwane J, Watrous B, Johnson S, Armstrong R
Phys Sportsmed
. 2016 Jul;
11(3):124-31.
PMID: 27409551
In brief: The authors tested the hypothesis that delayed-onset muscular soreness after running is related to the production of lactic acid during the exercise. Blood lactic acid concentration was measured...

Armstrong R, Laughlin M
Brain Res
. 2013 Sep;
258(1):173-6.
PMID: 24010185
Radiolabeled microspheres were used to measure blood flows (BF) among and within the ankle plantar flexor muscles of rats during swimming and during treadmill running. During swimming, BF was significantly...

Ingalls C, Wenke J, Nofal T, Armstrong R
J Appl Physiol (1985)
. 2004 May;
97(3):1067-76.
PMID: 15121748
Adaptations to repeated bouts of injury-inducing lengthening contractions were studied in mouse anterior crural muscles. Five bouts of 150 lengthening contractions were performed in vivo, with each bout separated by...

Dihydropyridine and ryanodine receptor binding after eccentric contractions in mouse skeletal muscle
Ingalls C, Warren G, Zhang J, Hamilton S, Armstrong R
J Appl Physiol (1985)
. 2003 Dec;
96(5):1619-25.
PMID: 14672973
The purpose of this study was to determine whether there are alterations in the dihydropyridine and/or ryanodine receptors that might explain the excitation-contraction uncoupling associated with eccentric contraction-induced skeletal muscle...

Lesniewski L, Miller T, Armstrong R
Muscle Nerve
. 2003 Sep;
28(4):493-500.
PMID: 14506722
Pathologic changes to alpha-motoneurons may contribute to decreases in skeletal muscle strength in diabetes. The present study examines this possibility. Female ICR mice (approximately 25 g) were given a single...

Rathbone C, Wenke J, Warren G, Armstrong R
Am J Physiol Regul Integr Comp Physiol
. 2003 Aug;
285(6):R1490-5.
PMID: 12920057
The purpose of this study was to determine if the elimination of satellite cell proliferation using gamma-irradiation would inhibit normal force recovery after eccentric contraction-induced muscle injury. Adult female ICR...

Warren G, Ingalls C, Armstrong R
Am J Physiol Regul Integr Comp Physiol
. 2002 Mar;
282(4):R1122-32.
PMID: 11893617
The goals of this study were first to determine the effect of temperature on the force loss that results from eccentric contractions in mouse extensor digitorum longus (EDL) muscles and...

Warren G, Ingalls C, Lowe D, Armstrong R
J Orthop Sports Phys Ther
. 2002 Feb;
32(2):58-64.
PMID: 11838581
In the workplace or on the athletic field, muscle strength can be decreased by 50% or more following performance of a relatively few high-force, eccentric contractions. The strength loss can...

Delp M, Armstrong R, Godfrey D, Laughlin M, ROSS C, Wilkerson M
J Physiol
. 2001 Jun;
533(Pt 3):849-59.
PMID: 11410640
1. The purpose of these experiments was to use radiolabelled microspheres to measure blood flow distribution within the brain, and in particular to areas associated with motor function, maintenance of...

Aviat Space Environ Med
. 2001 May;
72(5):471-6.
PMID: 11346014
Background: Exposure to reduced gravitational forces during spaceflight is associated with significant reductions in skeletal muscle mass and strength. The purpose of this study was to test the hypothesis that...
