Autor: Marcas M. Bamman, Roland L. Weinsier, B R Newcomer, Gary R. Hunter, D. Enette Larson-Meyer

Publikováno v: Muscle & Nerve. 24:654-661

It is not known what causes the well-established inverse relationship between whole-body exercise economy and exercise intensity. The purpose of this study was to: (1) evaluate muscle exercise economy at 45%, 70%, and maximum isometric strength using

Hemoglobin, muscle oxidative capacity, and VO2max in African-American and Caucasian women

Autor: G R, Hunter, R L, Weinsier, J P, McCarthy, D, Enette Larson-Meyer, B R, Newcomer

Publikováno v: Medicine and science in sports and exercise. 33(10)

The purpose of this paper was to determine whether differences in hemoglobin (Hb) and muscle aerobic capacity exist between African-American (AA) and Caucasian (CA) premenopausal women and to determine whether Hb and aerobic capacity of the muscle ar

Skeletal muscle metabolism in overweight and post-overweight women: an isometric exercise study using (31)P magnetic resonance spectroscopy

Autor: Roland L. Weinsier, B R Newcomer, Gary R. Hunter, D E Larson-Meyer

Publikováno v: International journal of obesity and related metabolic disorders : journal of the International Association for the Study of Obesity. 25(9)

OBJECTIVE: To investigate whether skeletal muscle anaerobic metabolism, oxidative metabolism or metabolic economy during controlled sub-maximal and near-maximal exercises is altered in overweight women after diet-induced weight reduction, and whether

Non-P(i) buffer capacity and initial phosphocreatine breakdown and resynthesis kinetics of human gastrocnemius/soleus muscle groups using 0.5 s time-resolved (31)P MRS at 4.1 T

Autor: B R, Newcomer, M D, Boska, H P, Hetherington

Publikováno v: NMR in biomedicine. 12(8)

High-time-resolution (0.5 s) (31)P MRS has been used to evaluate the initial phosphoreatine (PCr) breakdown and resynthesis kinetics, to calculate the non-P(i)(/non-bicarbonate) buffer capacity (betanon-P(i)(/non-bicarb)), and to calculate the consta

31P MRS measurement of mitochondrial function in skeletal muscle: reliability, force-level sensitivity and relation to whole body maximal oxygen uptake

Autor: D E, Larson-Meyer, B R, Newcomer, G R, Hunter, H P, Hetherington, R L, Weinsier

Publikováno v: NMR in biomedicine. 13(1)

The reliability, relation to whole-body maximal oxygen uptake (VO(2max)), and force-level sensitivity of (31)P MRS markers of mitochondrial function were studied in 39 normal-weight women. Following 90 s isometric plantar-flexion exercises at 45, 70

T1 measurements of 31P metabolites in resting and exercising human gastrocnemius/soleus muscle at 1.5 Tesla

Autor: B R, Newcomer, M D, Boska

Publikováno v: Magnetic resonance in medicine. 41(3)

This study has measured the apparent 31P T1 times at 1.5 T in human gastrocnemius/soleus muscle groups at rest, during exercise, and during recovery from a 90-sec submaximal plantar flexion exercise. T1 times were measured with a 10-sec time resoluti
