Osmosis through the Cell Membrane of an Egg Introduction: The cell or plasma membrane is made up of phospholipids and different types of proteins that move laterally. These include peripheral proteins, which are attached to the interior and exterior surface of the cell membrane. Integral proteins are embedded in the lipid bilayer.
Stretching may take a back seat to your exercise routine. The main concern is exercising, not stretching, right? Stretching may help you: Improve your joint range of motion Improve your athletic performance Decrease your risk of injury Understand why stretching can help and how to stretch correctly.
Benefits of stretching Studies about the benefits of stretching have had mixed results. Some show that stretching helps. Flexibility lab report studies show that stretching before or after exercise has little to no benefit.
Some research shows that stretching doesn't reduce muscle soreness after exercise, and other studies show that static stretching performed immediately before a sprint event may slightly worsen performance.
Stretching can help improve flexibility, and, consequently, range of motion about your joints. Improve your performance in physical activities Decrease your risk of injuries Help your joints move through their full range of motion Enable your muscles to work most effectively Stretching also increases blood flow to the muscle.
You may learn to enjoy the ritual of stretching before or after hitting the trail, ballet floor or soccer field.
Stretching essentials Before you plunge into stretching, make sure you do it safely and effectively. While you can stretch anytime, anywhere, be sure to use proper technique. Stretching incorrectly can actually do more harm than good.
Use these tips to keep stretching safe: Don't consider stretching a warmup. You may hurt yourself if you stretch cold muscles. Before stretching, warm up with light walking, jogging or biking at low intensity for five to 10 minutes. Even better, stretch after your workout when your muscles are warm.
Consider skipping stretching before an intense activity, such as sprinting or track and field activities. Some research suggests that pre-event stretching may actually decrease performance. Research has also shown that stretching immediately before an event weakens hamstring strength.
Instead of static stretching, try performing a "dynamic warmup. Everyone's genetics for flexibility are a bit different. Rather than striving for the flexibility of a dancer or gymnast, focus on having equal flexibility side to side especially if you have a history of a previous injury.
Flexibility that is not equal on both sides may be a risk factor for injury. Focus on major muscle groups. Concentrate your stretches on major muscle groups such as your calves, thighs, hips, lower back, neck and shoulders.
Make sure that you stretch both sides. Also stretch muscles and joints that you routinely use. Stretch in a smooth movement, without bouncing.
Bouncing as you stretch can injure your muscle and actually contribute to muscle tightness.
Breathe normally and hold each stretch for about 30 seconds; in problem areas, you may need to hold for around 60 seconds.
Don't aim for pain. Expect to feel tension while you're stretching, not pain. If it hurts, you've pushed too far. Back off to the point where you don't feel any pain, then hold the stretch. Make stretches sport specific. Some evidence suggests that it's helpful to do stretches involving the muscles used most in your sport or activity.MEMBRANE MODEL: The Bubble Lab The cell’s plasma membrane is a phospholipid bilayer with protein molecules imbedded in it.
The protein molecules transport other molecules through the membrane and into or out of the cell. Flexibility Lab Report 3 The testing procedures for the sit and reach test are simple and easy to understand.
The test should administered under lab conditions and participants should perform a brief warm up stretch so they do not pull a muscle or affect their body in a hurtful way. Shoes should also be removed for the test and any excess clothing that could affect the test should be removed.
Laboratory #3: Flexibility and Muscle Endurance Introduction: For this lab we will focus primarily on flexibility and muscular endurance measures related to good back health.
Good back health is related to (1) posture, (2) spinal mobility, and (3) spinal stability.
