Living Longer Stronger

Eilington Darden, Ph.D., Gainesville The purpose of the Living Longer Stronger program is to provide middle-aged people with a course at action to rebuild muscle mass. An average adult in the United States , for example, loses one-half pound of muscle per year between the ages of 20 and 50. As a 50-year old, his […]

The Effect of Weight-Bearing Exercise on Bone Mineral Density: A Study on Female Ex-Athletics and the General Population

Dr. John Ethefington, London St Thomas Hospital , London The aim of this retrospective cohort study was to estimate the changes in bone mineral density (BMD) as a consequence of exercise in female ex-athletes and age matched controls. Eighty-three ex-elite female athletes (67 middie and long distance runners, 16 tennis players, currently aged 40-65) were […]

Limited Range-of-Motion Lumbar Extension Strength Training

James E. Graves, Michael L. Pollock, Scott H. Leggett, David M. Carpenter, Cecily K. Fix, and Michael N. Fulton The purpose of this study was to evaluate the effect of limited rangeofmotion (ROM) resistance training on the development of lumbar extension strength through a 72° ROM. 33 men and 25 women (age = 30 ± […]

High Intensity Strength Training in Nonagenarians

Effects on skeletal muscle Maria A. Fiatarone, MD; Elizabeth C. Marks, MS; Nancy D. Ryan, DT; Carol N. Meredith, PhD; Lewis A. Lipsitz, MD; William J. Evans, PhD Muscle dysfunction and associated mobility impairment, common among the frail elderly, increase the risk of falls, fractures, and functional dependency. We sought to characterize the muscle weakness […]

Effect of Resistance Training on Lumbar Extension Strength

Michael L. Pollock,* PhD, Scott H. Leggett, MS, James E. Graves, PhD, Arthur Jones, Michael Fulton, MD, and Joe Cirulli. Development of a new testing machine, which stabilizes the pelvis, allowed us to evaluate the lumbar extensor muscles before and after training. Fifteen healthy subjects (29.1 ± 8 years of age) trained 1 day per […]

Comparison of Female Geriatric Lumbar-Extension Strength: Asymptomatic Versus Chronic Low Back Pain Patients and Their Response to Active Rehabilitation

Bryon Holmes, Scott Leggett, Vert Mooney, Jean Nichols*, Scott Negri, and An Hoeyberghs We compared lumbarextension strength between healthy asymptomatic geriatric females (HEAL) and symptomatic geriatric females (INJ) seeking medical attention for chronic low back pain. The INJ group used the MedX lumbarextension machine to perform isotonic exercise two times per week and were eventually […]

Pelvic Stabilization During Resistance Training: Its Effect on the Development of Lumbar Extension Strength

James E. Graves, PhD, Dina C. Webb, MS, PT, Michael L. Pollock, PhD, Jan Matkozich, Scott H. Leggett, MS, David M. Carpenter, MS, Dan N. Foster, MS, Joseph Cirulli The purpose of this study was to evaluate and compare resistance exercise training with and without pelvic stabilization on the development of isolated lumbar extension strength.
