Skeletal Muscle Hypertrophy

The effect of oral contraceptive use on the skeletal muscle regulatory pathways in response to resistance training has not been investigated previously. Here we present novel data, demonstrating that use of second-generation oral contraceptives in young untrained women increased skeletal muscle regulatory factor 4 expression and satellite cell number following 10 wk of resistance training compared with nonusers.

AbstractThe purpose was to analyze the influence of oral contraceptive use on body composition and strength levels in trained women. Twenty-three resistance-trained women participated in this study (age=27.4±3.4 years; fat mass=28.0±5.0%; BMI=22.9±2.7 kg∙m-2). Subjects performed an 8-week non-linear resistance-training program. Participants were assigned to either a group that consumed oral contraceptives (n=12, OC) or to a group that did not consume (n=11, NOC). Changes in body composition were measured by dual energy X-ray absorptiometry. Strength performance was assessed via the one maximum repetition (1RM) test in the squat and bench press, and muscular power was evaluated using the countermovement jump (CMJ) test. Fat free mass increased significantly in OC but no changes were seen in NOC. There were no changes in fat mass for either OC or NOC. Significant changes were found in bench press 1RM for both OC and NOC; similarly, increases in squat 1RM were reported in OC and NOC. Alternatively, no significant changes were found in CMJ in both OC and NOC. No significant between-group differences were detected in any of the studied variables. The use of oral contraceptives during resistance training did not negatively affect body composition or strength levels in trained women.

SummaryThe effect of Demulen (ethinyl estradiol 0.05 mg and ethynodiol diacetate 1 mg) and exercise on the level of plasminogen activators was studied in 25 women (12 controls and 13 contraceptive users).Plasma plasminogen activator level was increased by the use of the oral contraceptive and further increased by exercise. Urine plasminogen activator level was unchanged by the use of Demulen but, in both groups of subjects, was decreased by exercise.
