GOLLNICK, P. D., R. B. ARMSTRONG, C. W. SAUBERT IV, K. PIEHL, AND B. SALTIN. Enzyme activity and Jiber composition in skeletal muscle of untrained and trained men. J. Appl. Physiol. 33(3): 3 12-3 19, 1972.-Succinate dehydrogenase (SDH) and phosphofructokinase (PFK) activities and the histochemical identification of fiber types and localization of oxidative activity were determined on biopsy sam...

The aim of this study was to examine the effect of adding single-joint (SJ) exercises to a multi-joint (MJ) exercise resistance-training program on upper body muscle size and strength. Twenty-nine untrained young men participated in a 10-week training session. They were randomly divided in 2 groups: the MJ group performed only MJ exercises (lat pulldown and bench press); the MJ+SJ group perform...

the aim of this study was to investigate the effects of an acute bout of exhaustive resistance exercise on the expression of myogenesis modulators (myostatin (mstn) and myod) in male trained and untrained wistar rats’ fast and slow muscles. thirty rats were assigned to three groups: control (n=6), untrained (n=12) and trained (n=12). resistance exercise (weight lifting up a vertical ladder) was...

The present study investigated the effect of an acute exercise bout on the mRNA response of vascular endothelial growth factor (VEGF) splice variants in untrained and trained human skeletal muscle. Seven habitually active young men performed one-legged knee-extensor exercise training at an intensity corresponding to approximately 70% of the maximal workload in an incremental test five times/wee...

Endurance trained (n = 14) and untrained young men (n = 15) were compared regarding the fatty acid profile of the vastus lateralis muscle after 8 wk on diets with a similar fatty acid composition. The skeletal muscle phospholipids in the trained group contained lower proportions of palmitic acid (16:0) (-12.4%, P < 0.001) and di-homo-gamma-linolenic acid [20:3(n-6)] (-15.3%, P = 0.018), a lower...

BACKGROUND There is little information regarding the effects of concurrent training (endurance and resistance training performed in the same overall regimen) on blood lipid profile in sedentary male subjects. This study compared the effects of 3 different 8-wk training programs [endurance training (ET), strength training (ST) and concurrent training (CT)] on blood lipid profile and body composi...

The relationship between oxidative stress and some exercise components of resistance exercise (e.g. intensity, exercise volume) has not been clearly defined. Additionally, the oxidative stress markers may respond differently in various conditions. This study aims to determine the effects of progressive intensity of resistance exercise (RE) on oxidative stress and antioxidants in trained and unt...

conclusions performing large muscle group exercises first in re training and progressing to small muscle group produced greater anabolic hormonal response relative to reverse sequence in normal-weight young adult men. anabolic hormonal response to reos was blunted in the obese group. results reos did not affect number of repetitions in none of the groups. the average rating of perceived exertio...
