Scuba diving is a unique and beautiful experience that everyone should try at least once in their lifetime. Barring perhaps hydrophobics, almost anyone will find the experience of being underwater and floating along both exhilarating and relaxing at the same time. However, without proper training and preparation, scuba can also be a dangerous undertaking, with hazards that can affect the unprepared. With proper equipment and precautions, however, it is a safe and wonderful thing to do. Here are a few safety tips for the beginning scuba diver to consider before taking up diving in earnest.Training – Get certified. Take a training course that has official certification. If diving only for sport while on vacation like some people do, make sure that you have a certified instructor accompanying you on your dive. If diving in earnest, take a course that will actually give you a certificate for diving (not necessarily as an instructor, but one that will register you as a certified and capable scuba diver).Physical Conditioning – see a doctor before taking up scuba. Make sure that your doctor gives you a clean bill of health for the physical exertions required in scuba. While mentally relaxing, scuba diving involves enough physical effort that people with weak cardiovascular and especially respiratory systems can’t indulge in it. Asthma, a weak heart, tendencies for asphyxiation, all of these can disqualify a person from scuba diving. Also on the note of physical capability, knowing how to swim is a huge bonus. While not a necessity because scuba gear allows even those who don’t know how to swim to navigate underwater, it is nonetheless a very good thing to know. After all, you’ll be underwater…Avoid Places Where Bad Things Dwell – your training and certification in scuba will include a ranking that determines what levels of underwater hazards you’re trained to tackle. Avoid any places that you aren’t certified to handle. These areas will usually be very dangerous for the untrained, and will usually include special hazards that need their own branch of specialized scuba training or certain pieces of equipment to overcome. Examples include scuba diving in shark infested waters, ice floes, amongst coral reefs with toxic or aggressive underwater lifeforms, underwater caves, and shipwrecks.Proper Equipment Is A Must – your training and certification should also include care and maintenance of the scuba equipment. If you’re using your own equipment, make sure that you take excellent care of it, keeping it in top condition. No matter how skilled you are at navigating underwater, man is NOT biologically aquatic, and your equipment is all that’s keeping you alive down there. If renting equipment, give it much more than a cursory once-over. Examine it carefully to make sure there are no flaws in the gear that might cause it to fail during a dive. One of the hazards of scuba diving is drowning if your breathing apparatus gives out.Don’t Dive Alone – Always have a dive buddy or an instructor with you, as long as you are with someone who has more experience than you. If you’re diving with a buddy, don’t bring along someone who’s also a noobie if you yourself are new to the game. If you’re an old hand diving with a noobie, make sure that your partner knows how to follow your instructions once underwater. If you MUST dive alone, then at least have someone manning the boat on the surface to make sure you’ve got a buddy on overwatch.Study Conditions Before The Dive – listen to weather reports before the dive to make sure you don’t wind up diving during a typhoon or worse, a thunderstorm. Even if the conditions seem okay for diving, make sure to pack enough medical equipment to compensate for sudden changes in the weather. Even if it’s a heat wave and not something related to wind and rain, adverse weather can be problematic. Heat waves have been known to cause heat stroke and dehydration to divers who thought they were safe from the heatwave because they were underwater. Remember that water conducts heat more efficiently than air.Know When Bad Things Are Happening – learn and internalize the medical signs and symptoms of the following conditions, as they are the maladies that usually afflict divers. Hypothermia, dehydration, heat exhaustion, and asphyxiation are the things to watch out for, as well as a diver-specific malady called decompression sickness, which occurs when a diver’s body is submitted to and becomes accustomed to high pressures underwater, as well as having air bubbles form in the body from prolonged breathing of high pressure gas. Returning to the surface where the body no longer is subject to these pressures can lead to dizziness, sickness, and vomiting from system shock. It is in a way, comparable to a person being used to the thin air of mountain climbing, when the climber goes back to a normal atmosphere and breathes a higher concentration of oxygen.

The gears in mountain bikes just keep getting more and more intricate. The bikes of today have as many as 27 gear ratios. A mountain bike will use a combination of three different sized sprockets in front and nine in the back to produce gear ratios. The idea behind all these gears is to allow the rider to crank the pedals at a constant pace no matter what kind of slope the bike is on. You can understand this better by picturing a bike with just a single gear. Each time you rotate the pedals one turn, the rear wheel would rotate one turn as well (1:1 gear ratio). If the rear wheel is 26 inches in diameter, then with 1:1 gearing, one full twist on the pedals would result in the wheel covering 81.6 inches of ground. If you are pedaling at a speed of 50 RPM, this means that the bike can cover over 340 feet of ground per minute. This is only 3.8 MPH, which is the equivalence of walking speed. This is ideal for climbing a steep hill, although bad for ground or going downhill. To go faster you’ll need a different ratio. To ride downhill at 25 MPH with a 50 RPM cadence at the pedals, you’ll need a 5.6:1 gear ratio. A bike with a lot of gears will give you a large number of increments between a 1:1 gear ratio and a 6.5:1 gear ratio so that you can always pedal at 50 RPM, no matter how fast you are actually going. On a normal 27 speed mountain bike, six of the gear ratios are so close to each other that you can’t notice any difference between them.  With actual use, bike riders tend to choose a front sprocket suitable for the slope they are riding on and stick with it, although the front sprocket can be difficult to shift under heavy load. It’s much easier to shit between the gears on the rear. If you are cranking up a hill, it’s best to choose the smallest sprocket on the front then shift between the nine gears available on the rear. The more speeds you have on the back sprocket, the bigger advantage you’ll have. All in all, gears are very important to mountain bikes as they dictate your overall speed. Without gears you wouldn’t be able to build speed nor would you be able to pound pedals. The gears will move the pedals and help you build up speed.  There are all types of gears available in mountain bikes, all of which will help you build up a lot of momentum if you use them the right way.

There are several different kinds of rock climbing that people engage in for sport. Rock climbing first began to be recognized as a sport when it was independently developed from the rock climbing techniques of Victorian era mountaineering in the late eighteen hundreds. Over the years since then, a lot of specialized safety equipment and proven techniques for staying safe and making a secure, controlled ascent have been developed. However, the sport of rock climbing can still be split into two major divisions: free climbing and aid climbing. Free climbing uses only the natural features of the rock face being climbed, and is significantly more dangerous than climbing with the assistance of safety gear.

Even when safety gear is being used, however, many climbers try to follow the ethic that their climbing activities should not damage or change the surface of the rock face any more than is absolutely necessary. For some kinds of short distance rock climbing, such as bouldering, purists believe in free climbing assisted by some kind of pad on the ground to catch them if they fall. This allows them to climb without leaving marks in the rock. Cams are also a good way to climb without leaving too much of a mark on the surface, while driving spikes into the rock to use as handholds and places to tie rope lines is one of the more invasive ways of climbing.

Lead climbing is one of the most common types of rock climbing, where climbers go up in pairs and the lead (or topmost climber) is attached to the lower climber, or second, by a length of rope. Whoever is lowest at the moment is the second, and is in charge of belaying the rope, keeping the belaying system secured attached to the rock, and stopping the rope to keep the other climber from harm in case of a fall. While lead climbing, safety devices will usually be left on the mountain at regular intervals. For traditional lead climbing, these safety devices installed by the lead climber, will usually be removed by the second during the ascent. This leaves the climbing surface close to the way in which it was found, and leaves the same level of challenge and enjoyment for future climbers.

Top rope climbing is a variant on the two person climbing system where the one in charge of belaying the rope and keeping the system secure is at the top. The person at the top will place an anchor and help to hold the rope steady while the other climber makes his or her way upwards.

Not all rock climbing takes place outdoors ‘ indoor rock climbing is increasingly popular and is the way that many people start to get involved in the sport. Rock climbing walls with regular handholds can be built inside of a building to teach people climbing techniques and this style of climbing with holds on a wall is also sometimes used in sporting competitions and is a lot of fun in its own right.

Mountaineering, mountain climbing, top rope, bouldering or rock climbing, whatever you want to call it, these names all pertain to the wonderful and exciting sport of reaching the peak of a goal. Experienced climbers know the adventure and fun in store in climbing a mountain. There are many trails, sites and stopovers that can definitely provide you a whole new perspective. People sometimes need a change of scenery to refresh the body and the mind. Mountain climbing and exploring the outdoors can give the right setting for such needs. This is also a good opportunity to get closer to nature. Thus, it is best for you to explore this wholesome activity. This is one good way to challenge your body. This is also a way to stimulate the mind and spirit by giving it a refreshing drive. You will do more than just mere hiking when you go mountain climbing. You will also get to learn how to work well with other people in a group, proper balancing, controlling movements, following a lead and even taking safety considerations. Rappelling is also one thing that you can only enjoy here. It will definitely be one of the best decisions you will make in your lifetime. Thus, if you are interested in learning the many ways of mountain climbing and rappelling, you must do your homework. Research on how you can start on this activity and take initiative in making this plan a reality. Some Helpful Tips for Climbing and Rappelling Activities For most beginners, this exciting sport will have to be properly prepared to ensure safety and fun at all times. Here are some points to keep in mind when you go mountain climbing and rappelling. 1. Climbing Guides First consideration is the need to take caution at every step of the way. It is best to get the assistance of a climbing guide. Basically, the guide will keep you on track. Make sure that he or she is qualified enough to take on the task. A certification by the IFMGA or the International Federation of Mountain Guides Association will be a good assurance. 2. Get Proper Instruction There are many equipment, terms and techniques that you will encounter in climbing. These will come in handy as you communicate with fellow climbers and learn the various ways they do their climbing and rappelling. As such, it is best to get the right education when it comes to such things. There are instructions offered by climbing guides, groups or organizations that can cater to your level of ability. Be sure to take this opportunity. The beginners can be best taught the proper ways in climbing and rappelling through training. Indoor man-made rock walls will help in giving you a feel of what you will face outdoors. Most people find rappelling down more difficult than climbing up. If you train indoors, you can learn rappelling techniques until you are confident enough. This way, you can easily learn even if you are still trying to overcome your fears. You can also choose to get personal instruction on your rappelling abilities. The personal instructor can very well adjust to your pace and guide you in every detail that you need to focus on. 3. Have the Right Equipment Any climbing and rappelling endeavors must also be supported by the right equipment at hand. Make sure you have all the necessary things on hand. The helmet is a must to keep you head safe from any falling debris, bumps, or bruises. The climbing shoes must also be worn to keep you safe from any slippery steps. Check also the climbing package. Make sure you have all the tools needed like the food, rope, chalk, harness among many others. Make sure also that you take care of your equipment really well. For example, if you want to focus more on rappelling, you must keep the necessary things at hand. Protect your rappel and know how to use it when the need arises. By doing these things, you can easily focus on the fun experience. Conclusion Mountain climbing and rappelling may be foreign to you for now, but with the right research, preparation and training, you will definitely be one of those raving on how fun these adventures can get.
