Explosive power lifts are weight training exercises which require a very fast movement to be performed by the lifter in order to lift the weight. For instance, in a power clean , a barbell is quickly lifted from the floor and unto the upper chest; this must be performed fast in one dynamic movement otherwise it would not be possible to move the ...
The strength, or potential, of an explosive is the total work that can be performed by the gas resulting from its explosion, when expanded adiabatically from its original volume, until its pressure is reduced to atmospheric pressure and its temperature to 15°C. The potential is therefore the total quantity of heat given off at constant volume ...
‘The goal of this type of training is to acutely or over long-term training enhance power output in tasks such as jumping, sprinting, and throwing a ball.’ [6] The ambition in a complex training regime is not just to achieve better results in an individual workout but also to condition the athlete so they can perform more powerfully as a standard.
[1] [3] It is a form of power training which can involve throwing weights, jumping with weights, or swinging weights in order to increase explosive power. [4] The intention in ballistic exercises is to maximise the acceleration phase of an object's movement and minimise the deceleration phase.
The specified minimum strength requirement varies depending on where the information is sourced and the intensity of the plyometrics being performed. Chu (1998) recommends that a participant be able to perform 50 repetitions of the squat exercise at 60% of his or her body weight before doing plyometrics. Core (abdomen) strength is also important.
High explosives (HE, or high-order explosives) are explosive materials that detonate, meaning that the explosive shock front passes through the material at a supersonic speed. High explosives detonate with explosive velocity of about 3–9 kilometres per second (9,800–29,500 ft/s). For instance, TNT has a detonation (burn) rate of ...
The velocity of detonation is an important indicator for overall energy and power of detonation, and in particular for the brisance or shattering effect of an explosive which is due to the detonation pressure. The pressure can be calculated using Chapman-Jouguet theory from the velocity and density.
The test is performed by loading a 10-gram foil-wrapped sample of the explosive into a hole drilled into a lead block with specific dimensions and properties (a soft lead cylinder, 200 mm diameter and 200 mm high, with the hole 125 mm deep, and 25 mm diameter). [1] The hole is then topped up with sand, and the sample is detonated electrically ...
