The effects of protein and carbohydrate supplementation on body composition and muscle strength during resistance training

摘要: Laakso, Mia 2015. The effects of protein and carbohydrate supplementation on body composition muscle strength during resistance training. Department Biology Physical Activity, University Jyvaskyla, Master’s Thesis in Exercise Physiology. 89 pp. Introduction. importance for health performance are well known. Resistance training diet known to affect composition. purpose this study was examine the different post-exercise regimens development Methods. A total 78 healthy, recreational active men (mean ± SD: age 34.7 1.4, height 179.9 0.77 cm, weight 83.6 1.4 kg) were included study. All subjects completed a supervised program, which 4-week habituation period. After period, divided into three groups (protein, carbohydrate, protein+carbohydrate). Within each these groups, further powerstrength or hypertrophic-strength groups. Subjects kept 4-day dietary records first month 12-week Body determined using DXA at baseline, after training, period with supplementation. Cross sectional area knee extensor muscles measured ultrasound 12 weeks. Strength measurements done 8 12-weeks actual Muscle by both dynamic isometric leg press. Results. intake did not differ significantly between relative weight, but smaller than group recovery days (P < 0.05). Significant increases following all seen fat free mass 0.001) = 0.003) without differences Total android decreased while trunk unchanged 0.065). nutrition x time interaction detected 0.032), 0.001), 0.014).
