The Impact of Sitting All Day – Part 5

We use are wrists all the time.  More now as we live our lives on line meaning we use computers more and then we often go to the [...]

The hamstrings play a crucial role in many daily activities, such as, walking, running, jumping, and controlling some movement in the trunk. In walking, they are most important as an antagonist to the quadriceps in the deceleration of knee extension Most low back pain and sciatica problems will benefit from a regular routine of hamstring stretching. Tightness in the hamstrings places increased stress on the low back and often aggravates or even causes some of the conditions that lead to low back pain and/or sciatica pain. The hamstrings are a group of three muscles (Biceps Femoris, Semitendinosus & Semimembranosus) located in the back of the thigh. They run from the pelvis down to the knee, and help bend the knee and extend the hip. Because most daily activities including sitting do not stretch the hamstrings, they are often overly tight and specific stretching exercises are needed to keep them healthy and extended.  In addition strenuous exercises often contributes to tight hamstrings. Stretching your hamstrings before and after working out helps alleviate pain and tightness. Back pain sufferers and those with stiff knees will also benefit from a regular stretching routine. Tight hamstrings are a common finding in most people. However, you can do easy exercises to increase your hamstring length. Learn four easy exercises and be on your way to a more limber lifestyle. Stretch 1 Sit on the floor with both legs out straight. Extend your arms and reach forward by bending at the waist as far as possible while keeping your knees straight. Hold this position for 10 seconds. Relax. Repeat. Stretch 2 Sit on the floor with one leg out straight. Bend the other leg at the knee and position the sole of that foot against your opposite inner thigh. Extend your arms and reach forward over the one straight leg by bending at the bending at the waist as far as possible. Hold this position for 10 seconds. Relax. Repeat with the other leg. Stretch 3 Stand and cross your right foot in front of your left. Slowly lower your forehead to your right knee by bending at the waist. Keep both knees straight. Hold this position for 10 seconds. Relax. Repeat by crossing your left foot in front of your right. Stretch 4 Stand one foot from a wall and place your hands on the wall at shoulder height, shoulder-width apart. Take a step back with one leg while pushing into the wall. Keep your back straight and press your heels into the floor. Hold for 10 seconds. Step forward and repeat with the other leg. Remember massage can help release tight hamstrings.

So, you go to the gym regularly, follow all the latest exercises trends, but are still not getting the results you wanted.  It’s frustrating isn't it.  You want that sculptured body, but it seems elusive.  Well helps may be coming.  Until now scientists haven't been fully able to understand how muscle responds to exercise especially in the early stages of an exercises program - when we are tempted to give up because we aren't yet seeing the results. Scientists at Liverpool John Moores University (LJMU) and the Australian Catholic University in Melbourne have established a new technique for studying muscle growth in humans.  The technique, termed Dynamic Proteome Profiling, provides comprehensive coverage of the early changes that occur within human muscle in response to exercise training. This was the first data on the rate at which new muscle proteins are made when volunteers performed strength training exercises. Muscle is composed of thousands of different proteins and each protein makes a specific contribution to muscle function, for example, some proteins are responsible for movement while others are required to provide energy.  The proteins in muscle have a tough time and often become damaged, but in healthy cells a sophisticated recycling system keeps protein quality high by continually breaking down and remaking each protein. When muscle fibres grow in response to weight training the amount of specific proteins is increased, and therefore muscle becomes larger and stronger. Because of Dynamic Proteome Profiling, scientists are now able to identify exactly which proteins are most responsive to exercise and whether that response is due to more of the protein being made or less of the protein being degraded/ broken down by the cell’s recycling machinery. This profiling will allow a finer level of detail of muscle response to exercises which could lead to better training methods, nutritional strategies or medicines that can be used to promote muscle growth, and hopefully less frustration on getting the results from hours spent in the gym!
