...Introduction Mogul skiing is a fairly new sport that emerged as part of freestyle skiing back in the 1960’s and 70’s (Appelbe, 2010). Moguls are the bumps that are formed when skiers push down the snow as they ski downhill. The formation of moguls happens naturally with time on a frequently used slope. This unstable terrain was challenging to many and soon became a course to run on the slopes. In 1966, the first freestyle event took place in Attitash, New Hampshire but was not yet recognized as a sport. Later, however, the Canadian Freestyles Skiers Association was formed and mogul skiing was recognized by The International Ski Federation. Freestyle skiing was originally broken up into three distinct disciplines which were aerials, ski cross, and moguls. Moguls and aerials became Olympic sports in the early 1990’s, and ski cross became an Olympic sport for the first time at the 2010 Games (Appelbe, 2010). The mogul skiing event is a downhill event where the goal of the skier is to finish the run as fast as possible while maintaining control through a very unstable terrain filled with moguls and they also need to execute tricks and turns to impress the judges. The moguls measure approximately four feet tall and are approximately 3.5 meters apart, the slope also has two small jumps known as “kickers” due to the steep take off. Each mogul slope whether natural or man-made is different so the terrain is never exactly the same. There are several competition events for mogul...

...The strict pull-up is a bodybuilding-style pull-up in which the purpose is to maximally contract the muscles of the back and arms – mostly the lats, biceps, and forearms. The rest of the body is meant to remain in enough tension to maintain a rigid structure. With the strict pull-up, the body should not move except for those joints which are required to perform the movement itself, the elbows and shoulders. All other joints should remain relatively stationary, as they shouldn’t contribute to the force production required to execute the exercise. This is the classic exercise that people think of when they hear about pull-ups. (LINK) So, basically you need to increase muscle hypertrophy — in particular, the lat and bicep muscle. You have to train your core too because you have to keep your other parts of the body tense while doing pull-up, so it is easier for you. Below will be the exercises I can think of to improve your strength. If you do it properly, you should be sore the next day. Please do not do the same workout consecutively for two days because when muscles are sore/ torn, they need at least 24-48 hours to repair (usually 24 hours, unless you really trained hard). Switch the muscle group you trained daily, e.g., Monday train back muscles and arms, Tuesday train shoulders and etc. But actually I can’t think of any other part of the muscle that you need to train, so I will just give you what you can do to improve the strength of your back and arms. So as long as you...

...30-Minute Chest Workout: Day 1 Exercises for Day 1 By Nick Nilsson, C.P.T. A. Exercise 1a Bench Press Sets: 3 Reps: 8-10 Rest: 20 Seconds Lie on the bench, grab the bar underhand, and pull your torso up and forward, resting your head on the bench before the rest of your body. Your eyes should be under the bar. This should also cause your knees to bend 45 degrees so that your feet are planted far back—it's OK if the balls of your feet are in contact with the floor—but your heels are in the air. Now switch to an overhand, shoulder-width grip. Lift the bar off the rack and hold it directly above your chest [1]. Squeeze the bar hard and arch your upper back. Lower the bar to just below your nipples [2]. Once the bar touches your chest, push your feet hard into the fl oor (dropping your heels if they're up). Press the weight up, focusing on pushing the bar back slightly toward your face. When the bar is halfway up, begin fl aring your elbows outward to lock it out. That's one rep. B. Exercise 1b Dumbbell Fly Sets: 3 Reps: 8-10 Rest: 20 Seconds Hold a dumbbell in each hand and lie back on a bench as you would to perform a bench press. Press the weights over your chest and turn your palms so that they face each other [1]. Slowly spread your arms and lower them in an arcing motion until the weights are about level with your shoulders [2]. Hold the stretched position for five seconds. Now squeeze your pecs and draw your arms back to the starting position. That's one rep. ...

...separated by a longer rest period. The total number of circuits performed during a training session may vary from two to six depending on your training level (beginner, intermediate, or advanced), your period of training (preparation or competition) and your training objective. Planning Identify on paper 3 to 4 circuits of 6 to 10 exercise that can be performed with the available resources. In each circuit try to ensure that no two consecutive exercises exercise the same muscle group. e.g. do not have press ups followed by pull ups. The exercise circuit should be set up so that you work each body part as follows: Total-body, Upper-body, Lower-body, Core & Trunk, Total-body etc. For each circuit I have a set of linoleum squares (6 inches by 6 inches) with an exercise written on each that I lay by the equipment to indicate to the athletes the required exercise at each stage of the circuit. You could use plain card or paper and include an explanation as to how to perform the exercise, duration and recovery. A set of 25 Circuit Training Cards has been kindly created and donated by Maree Buchanan, a Physical Education Teacher from Bron Bay, Australia. All that you have to do is download the file, print off the 25 cards and laminate them. It is important to conduct a warm up at the start of the session and a cool down at the end of the session. The following are examples of exercises that can be used in a circuit training session: * Upper-body...

The original OPERATION PHYSICS activity sequence to improve physics teaching and learning in upper elementary and middle schools was funded by the National Science Foundation. Original Material Copyright 1992 by American Institute of Physics Materials edited and photoduplicated with permission. FORCES & MOTION INTRODUCTION WORKSHOP LEADER’S TOPIC INFORMATION INTRODUCTION TO FORCES & MOTION An understanding of force and motion is fundamental to the study of almost all other physics-related topics. Yet it is a topic often overlooked or only cursorily introduced in elementary and middle school science, even though it is a topic typically identified for inclusion in the curriculum for these grades. A primary reason for this is that many teachers do not feel comfortable about their own understanding of the topic. Consequently, this may be the most needed of all of the OPERATION PHYSICS workshops. This workshop leader’s notebook is divided into two parts: PART ONE Motion Part One begins by introducing participants to the concepts of space and time....

At the same time, we never seemed to have a lot of stuff on the shelves. My mother would put together a shopping list for my father to buy from on Saturday mornings. It always had on it what we needed in specific quantities – one box of oatmeal, two boxes of cornflakes, two dozen eggs, one can of asparagus, three cans of corn, etc. It was after she became ill with heart trouble and was in the hospital for an extended stay that my father took over the shopping list. We began to be short of butter or flour or eggs. After a couple of weeks of this I decided that it was time to ask my mother how she did what she did. By that time she was in the University Hospital 150 miles away, so I had to write for an explanation of...

...FITT PRINCIPLE The FITT Principle is a set of rules that must be adhered to in order to benefit from any form of fitness training program. * FREQUENCY – How often you train * INTENSITY – How hard you train * TIME – How long you train * TYPE – What you train PROGRESSION The principle of progression implies that there is an optimal level of overload that should be achieved. * A gradual and systematic increase of the workload over a period of time will result in improvements in fitness without risk of injury. * You should not train hard all the time, as you'll risk overtraining and a decrease in fitness. SPECIFICITY The Specificity Principle simply states that exercising a certain body part or component of the body primarily develops that part. * The Principle of Specificity implies that, to become better at a particular exercise or skill, you must perform that exercise or skill. OVERLOAD The exercise science principle of overload states that a greater than normal stress or load on the body is required for training adaptation to take place. * What this means is that in order to improve our fitness, strength or endurance, we need to make the workload more difficult than your daily tasks. 5 COMPONENTS OF HEALTH RELATED FITNESS * Cardiorespiratory Endurance: the ability of the heart, lungs and blood vessels to utilize and send fuel and oxygen to the body’s tissues during long periods of activity * Muscular Strength – The amount of force...

The first source is the book The Atlantic Migration, written by Professor Marcus Lee Hansen in 1942. Hansen was the son of a Danish immigrant and a Norwegian immigrant and a professor of history at the University of Illinois. He conducted research on the history of American immigration for four years to write this Pulitzer-prize winning book. It is a secondary source, which allows Hansen to look at emigration and immigration factors from hindsight. The content of this book is valuable because it mentions the push factors in Europe, the pull factors in each colony, and why people would want to leave for...

...Photography Photography is undoubtedly one of the most important inventions in history -- it has truly transformed how people conceive of the world. Now we can "see" all sorts of things that are actually many miles -- and years -- away from us. Photography lets us capture moments in time and preserve them for years to come Today, photography is characterized by a rapid growth in the development of technology and ideas. Each year, millions of pictures are taken and an astonishing array of new films, cameras and imaging systems enter the market. One of the great attractions of the photography field is the ease with which basic skills can be learned. The word ‘photography’ comes from the Greek term ‘drawing with light’. Without light there is no photograph. Photography is about seeing, balancing and interpreting the light. Composition of Photography The Camera: The materials that are usually used in creating a camera are metal, glass, plastic, wood, and mirrors. The Film: Collodion: This substance transformed photography. This a viscous mixture of gun cotton that is dissolved in alcohol that then creates a thin film. It is then mixed with silver bromide, silver iodide or silver chloride. This substance reduced exposure time to seconds instead of hours. Film: The first type of camera film was produced when the collodion was combined with celluloid, a flexible plastic. This film started to be sold with “Kodak” in 1889 along with the worlds first box camera. Chemicals...
