    Project Website: http://www.lorenzpotthast.de/deceleratorhelmet/ || German Version: https://vimeo.com/44615898 || See also: www.lorenzpotthast.de The Decelerator Helmet offers an experimental approach to an essential subject of our globalized, fast moving society. The technical reproducible senses are consigned to an apparatus which allows the user a perception of the world in slow motion. The float of time as apparently invariant constant is broken and subjected under the users control. In the inside of the helmet the Video-signal of a camera is processed by a small computer. The slowed down images are displayed right before the users eyes via a Head-Mounted Display and simultaneously shown at a monitor on the outside. In three different modes the lapse of time can be influenced through a remote control. The Idea to decouple the personal perception from the natural timing enables the user to get aware about his own relationship to time. The helmet works as a „reflection-bubble“ in which the relations between sensory perception, environment and corporeality are disputed. The technique of the Decelerator extends the awareness of time and transforms the concept of present in a constructed, artificial state. On a different Level the helmet dramatically visualizes how slowing down under all circumstances causes a loss of actuality and as idea is inconsistent with it´s Environment. Technical enhancement as a tool to give us control about our perception, asks the question how far this influence can go, before we are all lost in how we want to see reality. The Decelerator unintentionally explores how aspects of this shift to a personalized perception could change our view of the world.

    • 2-arm kettle bell swing with full acceleration and deceleration

      Video on April 13, 2013 Resistance: 36 kg (79.2 lb.) kettle bell A normal kettle bell swinging movement does not emphasize maximal acceleration and deceleration of the load through the full range of movement (it is a focus only on explosive hip extension). When you introduce the additional dynamics, this movement is dramatically different physically and mentally. Mentally it feels the same as doing an Olympic clean or snatch with the focus on maximal velocity and maximal explosiveness to overcome inertia. However, with this movement, there is both a pull and a push, not just a push as in Olympic movements: active deceleration eliminates the “free ride” effect created by the explosive acceleration ( i.e. the rapid switching of the magnitude and direction of the force vector at both endpoints affects entire body control dramatically). What this means is that even though the kettle bell is moving outward and is still accelerating from hip extension you are simultaneously braking it with full lat and ab/core recruitment well priorto the return or inward trajectory of the kettle bell. Complementary musculature must be fully engaged with 100% duty cycle in order to reduce the cycle time (time to execute one rep) to a minimum. Physically, there is a powerful engagement of the abdominals, other core muscles and the latissimus dorsi that is lacking without the dynamics (there is no “free ride” of kettle bell travel anywhere in the range of motion). Exhalation is in the outward movement and inhalation during the inward movement but a significant amount of your inhaled air must be retained to maintain outward pressure on the diaphragm in order to keep the torso stiff like in a squat when coming out of the bottom. Additionally, because each cycle is only one second in duration and the breathing is synchronized to movement, you must exhale a significant air volume in one-half second which immediately switches to the inhalation phase of only one-half second. Because of the metabolic power demand of this movement and the constrained breathing requirements, this is necessarily a noisy exercise during a maximal effort! This movement is measured in speed of movement. The static load is 36 kg but the dynamic load is a multiple of the static load (Momentum = mass x velocity and Force = mass x acceleration). 10 cycles (“reps”) were completed in 12 seconds for a time of 1.2 sec/cycle. I learned about this movement from a video by Mike Visscher in San Diego, CA at www.ignitionfitness.com. For more information: www.eyp.tv www.supermodel2.com

        • slow motion study of the human body ballistically swinging a heavy kettle bell with maximal acceleration and deceleration

          Video on April 20, 2013 Resistance: 36 kg (79.2 lb.) kettle bell Video organization: The movement is captured from three camera angles: side, front, and rear. The first clip presents the side view at real-time speed, the second clip is from the side in slow motion (20% of real-time speed), the third clip is from the front in slow motion, and the fourth clip is from the rear in slow motion. Observe how the energy flows through the body's kinetic chain during the accelerative and decelerative phases as different muscle groups contract and relax in sequence. Note that hip flexion and leg flexion are strongly engaged ("pulling") in addition to hip hip extension and leg extension ("pushing"). I cannot think of any other movement that recruits full body pulling and lower body pushing anywhere near this degree; it is achieved because of the inertia of the kettle bell creates a large additional force in addition to gravity whose force vector is around 30 to 40 degrees greater than orthogonal to the gravitational force and pointing away from you (i.e. pulling you forward). This is the force you are pulling against when you decelerate and reverse the direction of the kettle bell (which then is rapidly switched to the gravitational force as you accelerate it downward.) Trunk stabilization with both the abdominal complex and their antagonists the erector spinae (http://dynorock.files.wordpress.com/2011/01/mm_erector_spinae.jpg) are at a premium to manage the dynamic load. The entire body is severely challenged to maintain balance via proprioception. If balance is lost it is very difficult to recover and the kettle bell often must be released to avoid falling forward or flying backward. This movement imposes a great training effect for enhancing agility. It is a neurological tour de force. A normal kettle bell swinging movement does not emphasize maximal acceleration and deceleration of the load through the full range of movement (it is a focus only on explosive hip extension). When you introduce the additional dynamics, this movement is dramatically different physically and mentally. Mentally it feels the same as doing an Olympic clean or snatch with the focus on maximal velocity and maximal explosiveness to overcome inertia.

                  A film which developed out of my idea for a durational performance installation at University of Limerick in 2010, dealing with the perception of time, repetition and lots of paper with music written by La Monte Young. A sense of floating, peaceful events over and over again.. The film is quite different though. We shot the film during the evening and nighttime in a corridor of the university building. The perception of time while waiting for something. passing time, elongated. transform and sustain. Still in progress as a side project, but started in Limerick, 2010.

                    Berlin, 2008 Inspired by Edward Hoppers painting “Excursion into Philosophy this film is about two lonely people who are unable to escape from the monotony of their lives. Unable to communicate with each other they spend a moment of tenderness, which leaves them with an even deeper feeling of emptiness.

                      Este vídeo foi um exercício feito em aula, assim como boa parte sos demais deste canal. Seu objetivo era utilizar de keyframes para simular acelaração, desaceleração e velocidade constante em objetos. Os objetos escolhidos foram tanques que eu criei para um game que estou desenvolvendo com um amigo meu, Wanderon Houpillard. Escolhi como música a "A Cavalgada das Valquírias", de Richard Wagner, por ser um tanto heróica e bélica (combinando com tanques). De cima para baixo, simulei velocidade constante (apenas criando dois keyframes e mudando a posi;cão do objeto), desaceleração (ease in), acelera;cão (ease out) e um movimento que começa com uma aceleração e termina com uma desaceleração (easy ease). Observação: como criar os eases: EASE IN: selecionar último keyframe, click com botão direito do mouse, escolher a opção Keyframe Assistante e marcar Ease in. EASE OUT: selecionar o primeiro keyframe, click com botão direito do mouse, escolher a opção Keyframe Assistante e marcar Ease out EASY EASE: no primeiro e no último keyframe, click com botão direito do mouse, escolher a opção Keyframe Assistante e marcar Easy ease.
