Studies related to Power Output and Vitamin D

A Systems-based Investigation Into Vitamin D And Skeletal Muscle Repair, Regeneration, And Hypertrophy

Effect Increase
Values 14% improvement in torque at 48 hours after exercise and 13.7% improvement at 7 days.
Trial Design Randomized trial
Trial Length 1-6 months
Number of Subjects 20
Sex Male
Age Range 18-29
Notes for this study:
20 healthy males who were supplemented with either 4000 IU vitamin D or placebo underwent muscle damage through eccentric quad exercises and torque generation post-damage was measured at two different speeds up to 7 days after the eccentric exercise. Torque was recovered more quickly sin the supplemented group at slower speeds, and trended toward significance at quicker speeds.
