Each exercise mode can lead to a specific effect. On the other hand, herbal supplements increase the effects of exercise. Yet the interactive effect of exercise mode and Ursolic Acid (UA) on the Brown Adipose Tissue (BAT) has not been well explored. The aim of the present study was to investigate the effect of 12-week Aerobic Training (AT), Resistance Training (RT), and High Intensity Interval Training (HIIT) along with UA supplementation on muscle FNDC5 and adipose tissue UCP1 gene expression a...
Torque and Electrical Activation of the Rectus Femoris Muscle at Distinct Joint Angles: A Case Study

The angulation of knee and hip joints affect isometric contractions of Rectus Femoris muscle (RF) during knee extension. Literature states that torque-angle relationship depends on muscle length and neuromuscular electrical activation. However, it is still not clear whether the maximum neuromuscular activation changes concomitantly with the change in the joint angles considering the presence of muscle shortening. We present a case study in which we analyzed changes in neuromuscular activation an...
A Novel Oblique Impact Test Rig for Testing Helmet

In this work, a new test rig is introduced to assess various head impact scenarios on different types of helmets. The test rig is a free-fall system where a helmeted headform is suspended instead of being placed on a basket frame and detaches from the system before the impact allowing an unrestricted motion. The proposed testbed showed to be effective in performing helmet impact tests at different angles. The test rig is particularly effective in tests at steep anvil angles, such as 15°, which ...

Tools applied today in the Functional Training (FT) have long been used in general fitness programs, but systematic use and scientific interest are recent phenomena. Thus, there are many methodological conflicts and divergences in the prescriptions of this method. For example, some studies have associated FT with the use of instability in many exercises, while others use unstable bases in a small portion of training, or simply do not use. Thus, there is still an absence of a systematic FT model ...
