Cure rates of youth with Acute Lymphoblastic Leukemia (ALL) have increased in the past decades, but survivor's quality of life and physical fitness has become a growing concern. Although previous reports showed that resistance training is feasible and effective, we hypothesized that a more intense exercise program would also be feasible, but more beneficial than low- to moderate-intensity train...

Putman, C. T., M. P. Matsos, E. Hultman, N. L. Jones, and G. J. F. Heigenhauser. Pyruvate dehydrogenase activation in inactive muscle during and after maximal exercise in men. Am. J. Physiol. 276 (Endocrinol. Metab. 39): E483– E488, 1999.—Pyruvate dehydrogenase activity (PDHa) and acetyl-group accumulation were examined in the inactive deltoid muscle in response to maximal leg exercise in men. ...

Background: The determinant role of different movements to strengthen the quadriceps on rate of knee joint co-contraction, hamstring to quadriceps muscle activity ratio and vastus medialis to vastus lateralis muscle activity ratio provides useful information for therapists, coaches and athletes about the role of each movement in the rehabilitation of patients with anterior cruc...

BACKGROUND β-Hydroxy-β-methylbutyrate-free acid (HMB-FA) has been ingested prior to exercise to reduce muscle damage, however the effects of HMB-FA supplementation on hormonal, strength and power adaptation are unclear. METHODS Sixteen healthy men were matched and randomized into two groups and performed six-week resistance training while supplementing with either HMB-FA or placebo (3 g per d...

BACKGROUND StemSport (SS; StemTech International, Inc. San Clemente, CA) contains a proprietary blend of the botanical Aphanizomenon flos-aquae and several herbal antioxidant and anti-inflammatory substances. SS has been purported to accelerate tissue repair and restore muscle function following resistance exercise. Here, we examine the effects of SS supplementation on strength adaptations resu...

Previous research has compared the effects of trunk inclination angle on muscle activation using barbells and Smith machines in men. Whether similar effects occur with the use of dumbbells or in women remains unknown. The purpose was to compare upper extremity surface electromyographical (EMG) activity between dumbbell bench, incline, and shoulder presses. Dominate arm EMG data were recorded fo...

STUDY OBJECTIVES This study was developed to investigate the influence of thoracic and upper-limb muscle function on 6-min walk distance (6MWD) in patients with COPD. DESIGN A prospective, cross-sectional study. SETTING The pulmonary rehabilitation center of a university hospital. PATIENTS Thirty-eight patients with mild to very severe COPD were evaluated. MEASUREMENTS AND RESULTS Pulmo...

The purpose of this study was to determine if the type and intensity of aerobic training affects performance in a subsequent strength-training session after varying periods of recovery. Sixteen male subjects participated in the study and were divided into 2 groups based on aerobic training, high-intensity intervals (MAX n = 8) and continuous submaximal (SUB n = 8). Each subject performed 4 sets...

The use of the stability ball as a platform for upper-body resistance training has gained much attention in recent years. However, the efficacy of such training regimens remains largely unstudied. The purpose of this study was to evaluate the influence of platform (unstable vs. stable, stability ball vs. flat bench) on strength and work capacity during barbell chest-press exercise. We also soug...
