EFFECTS OF A 7-WEEK STRENGTH PROGRAM AND PROTEIN SUPPLEMENTATION ON HYPERTROPHY, MAXIMAL STRENGTH, AND POWER

T. Kuehn, C. Rivinius, R. Lopez, & A. Anderson University of Mary, Bismarck, ND This study was approved by the University of Mary Institutional Review Board. Purpose: The purpose of this study is to see the effects that a 7-week strength program combined with supplementing either whey protein, chocolate milk, or control has on quadriceps and hamstring hypertrophy, maximal strength and power. Methods: A study of 14 healthy subjects, ages 18-25 years old consisting of males and females (9 males, 5 females). Baseline assessments were taken; Wingate, 1 repetition maximum (1RM), Skinfold, circumferential measurements bilaterally. Subjects were randomly assigned into three different groups; control(w), chocolate milk(cm), and whey protein(wp). Subjects were prescribed an exercise routine of 3 sets of 10-12 repetitions at 70% 1RM. The exercise included: unilateral leg press, leg curl and leg extension were done on both legs with a two day rest period in between for a duration of 7 weeks. Post workout supplement was consumed after each workout. At the end of the study the baseline measurements were reassessed. Statistics: One-way Analysis of Variance. Results: No significant difference was found (p\u3e.05) between the supplement groups and the control for any of the strength and Wingate assessments after 7 weeks of training. Conclusions: This study found that supplementing with chocolate milk or protein did not significantly impact strength gains in the first 7 weeks of resistance training.
