To test the hypothesis that a smaller quantity of high intensity (HI) as opposed to a larger quantity of moderate intensity (MI) swim training would result in adaptations more specific to the short performance times of swimming competitions, two groups of elite university swimmers were tested before and after 6.5 weeks of specific HI or MI intermittent swim(More)
To investigate biochemical, histochemical and contractile properties associated with strength training and detraining, six adult males were studied during and after 10 weeks of dynamic strength training for the quadriceps muscle group of one leg, as well as during and after a subsequent 12 weeks of detraining. Peak torque outputs at the velocities tested(More)
OBJECTIVE The aim of this study was to demonstrate the feasibility of using samples obtained through muscle biopsy to assess a wide range of cellular properties, some of which may be abnormal in myalgia. Given the recent emphasis on the role of excitation-contraction coupling in health and disease, special emphasis is given to the characterization of the(More)
The diagnosis of thoracic outlet syndrome (TOS) is intrinsically difficult, and the literature about it is full of confusing terminology. Symptoms may arise due to compression of neural and/or vascular elements in one or more of three different locations. A number of tests were developed during the early part of this century, and a variety of syndromes have(More)
Two pressure measurement techniques (catheter and bulb) were used to decompose the effects of tendon loads on carpal tunnel pressure (CTP). The catheter technique measures true hydrostatic pressure, whereas the bulb technique is a estimate of contact force or pressure on the median nerve. Eight cadaveric wrists were moved through a range of(More)
This study investigated the hypothesis that the duration of aerobic-based cycle exercise would affect the adaptations in substrate and metabolic regulation that occur in vastus lateralis in response to a short-term (10 day) training program. Healthy active but untrained males (n = 7) with a peak aerobic power ( $$ \dot{V}{\text{O}}_{{ 2 {\text{ peak}}}} $$(More)
Physical assessment of 146 female workers in highly repetitive jobs found 54% to have evidence of musculoskeletal disorders in the upper limb that are potentially work-related. Many workers had multiple problems, and many were affected bilaterally (33% of workers). Muscle pain and tenderness was the largest problem, both in the neck/shoulder area (31%) as(More)
To investigate sex differences in the organization of enzyme activities of energy supplying metabolism in skeletal muscle, samples of the vastus lateralis were extracted from active but untrained males (n = 16) and females (n = 17), ranging in age from 18 to 22 years. Muscle tissue from 2 different biopsy samples from each subject were analyzed for enzymes(More)
This study aimed at investigating the relative roles of the duration versus intensity of exercise on the metabolic adaptations in vastus lateralis to short-term (10 day) aerobic-based cycle training. Healthy males with a peak aerobic power ( $$ {\dot{\text{V}}\text{O}}_{{ 2 {\text{peak}}}} $$ ) of 46.0 ± 2.0 ml kg−1 min−1 were assigned to either a 30-min (n(More)
To examine the hypothesis that increases in fiber cross-sectional area mediated by high-resistance training (HRT) would result in a decrease in fiber capillarization and oxidative potential, regardless of fiber type, we studied six untrained males (maximum oxygen consumption, 45.6 +/- 2.3 ml. kg-1. min-1; mean +/- SE) participating in a 12-wk program(More)
