Mouthguards help prevent orofacial injuries in many physical activities, commonly to the maxillary incisors. Mouthguards have many different properties which can be idealized. One property involves the amount of impact force the mouthguard can dissipate, commonly referred to as shock absorption. The aim of this study was to improve shock absorption capabilities beyond the protection that a mouthguard made of Ethylene Vinyl Acetate (EVA) can offer. A Nickel-Titanium (NiTi) and/or foam intermediate layer was placed between EVA. Seven configurations were fabricated at 3 different thicknesses. The configurations consisted of an intermediate layer composed of NiTi, foam, or NiTi/foam. The NiTi …
Predicting Chest Press Strength From A 4rm Triceps Brachii Exercise In Trained Women, Krystina Nadia Moschella
Predicting Chest Press Strength From A 4rm Triceps Brachii Exercise In Trained Women, Krystina Nadia Moschella

Determining maximal strength is important when developing a resistance exercise program for trained athletes. The most frequent strength procedure used to evaluate maximum strength is the 1RM test. However, risk of injury from a 1RM test increases for the athletes, therefore a 4RM test is used in the following study. The purpose of the study is to test whether there is a linear relationship between the bench press and the triceps rope extension exercise. A secondary purpose is the development of a prediction equation for the purpose of prescribing bench press exercise loads from triceps brachii loads using a 4RM …
