Push-Ups vs. Bench Press Differences in Repetitions and Muscle Activation between Sexes. Open
Push-ups are an ubiquitous resistance training exercise. While exhibiting a relatively similar upper body motion to the bench press, there are substantial differences in repetitions when employing similar relative loads. The objective was …

Acute Effects of Unilateral Self-Administered Static Stretching on Contralateral Limb Performance Open
**Background:** Prolonged static stretching (SS) has been shown to impair subsequent performance of the stretched muscle. There is some evidence that unilateral SS can have crossover or global effects on range of motion (ROM), but there is…
