The Effects of Myofascial Release With Foam Rolling On Performance

In this paper, 26 subjects performed a series of planking exercises or foam rolling exercises and then performed a series of athletic performance tests (vertical jump height and power, isometric force, and agility). Fatigue, soreness, and exertion were also measured. The results were as follows: There were no significant differences between foam rolling and planking […]


In this paper, 13 collegiate male wrestlers with >1 year of strength training were randomly assigned to 1 of 2 groups: Chain Bench Press or Plate Bench Press to see which would improve explosive power measured using a Plyometric push up on a force plate more. The athletes performed a Plyometric push up, Chain/Plate Bench […]


In this paper, published this month, 20 subjects had one leg randomly assigned to High-Frequency training (5 x per week) and the other to Low-Frequency (2-3 x per week). Muscle cross-sectional area and 1 repetition maximum were assessed at baseline and after 8 weeks of training. Some individuals showed greater muscle mass and strength gains […]

Comparison Between Unilateral and Bilateral Plyometric Training on Single and Double-Leg Jumping Performance and Strength

In this paper, the authors explored the effects of unilateral and bilateral plyometric training on single and double-leg jumping performance, maximal strength, and rate of force development (RFD). Fifteen moderately trained subjects were randomly assigned to either a unilateral (U, n = 7) or bilateral group (B, n = 8). Both groups performed maximal effort […]

Factors Related to Average Concentric Velocity of Four Barbell Exercises at Various Loads

In this paper, the authors wanted to see whether individual factors such as training experience or anthropometrics influence the average concentric velocity (ACV) during a repetition. Therefore, the purpose of this study was to determine whether training age, current training frequency, limb length, height, and relative strength are related to ACV at loads between 35 […]
