Too much stress isn’t good for your body it causes your Blood pressure rises Breathing becomes more rapid Digestive system slows down Heart rate (pulse) rises Immune system goes down Muscles become tense We do not sleep. To cope with stress try having a massage‚ go to a sauna and‚ find out what is stressing you out and try to find a solution to your stress. Sleep/Rest Sleep is essential. It is not an option. Regular

Quads Your quadriceps are the strongest muscle group in your body because they control it’s heaviest bone- the femur. Stretch to relax them after a run. Knees connective tissue such as your ligaments & tendons‚ take longer than muscles to adapt to the rigorous of running. Increase your weekly run time by just 10 per cent from week to week to give your knee a chance to catch up to your muscles. Soft

Muscle contractions happen when muscle fibers are stimulated‚ which can cause one of many types of contractions. Isometric contractions‚ which means that tension happens in the muscle but there is no change in muscle length‚ therefore there is no movement of the muscle itself. An example of Isometric contractions would be strength training‚ such as holding a weight still‚ which happens in the biceps brachii. The biceps brachii the gets more tension‚ but the muscle length stays the same. As for isotonic

created differently to provide athletes with different benefits. As well‚ these many different protein powders help people achieve their athletic goals more quickly like losing weight‚ building muscle‚ or endurance running. The benefits of using Protein powder outweigh the costs as protein promotes muscle and strength development‚ it allows athletes to reach their goals more quickly‚ and there are a wide variety of protein products

Plyometrics are training techniques used by athletes in all types of sports to increase strength and explosiveness. Plyometrics consists of a rapid stretching of a muscle (eccentric action) immediately followed by a concentric or shortening action of the same muscle and connective tissue. The stored elastic energy within the muscle is used to produce more force than can be provided by a concentric action. Researchers have shown that plyometric training‚ when used with a periodized strength-training

blood supply would increase because their legs would need more energy. This means that there would be more blood circulating in their legs than normal because they are being overworked. During acute exercise muscle pliability increases allowing a greater range of movement. Acute exercise causes muscle fibre tears. Energy Systems Response to Acute Exercise: An energy systems response to acute exercise happens when the exercise is of a high intensity‚ which is too much for the cardiovascular and respiratory

your legs than normal because you are overworking them. Your muscles and all your body organs need more energy and oxygen; this is because your body is working more than usual. Your body needs to do many things such as sweat‚ which helps you cool down‚ and to get energy to all of your cells in your body to help you carry on exercising‚ if your body didn’t do this‚ you wouldn’t be able to carry on exercising. During acute exercise your muscle pliability increases which allows a greater range of movement

build muscle strength. Unlike protein‚ creatine does not help to repair muscles or build muscle but allows the body to have more energy to work harder. Creatine is naturally found in the body and in foods such as seafood and red meats.1 Many studies have been conducted in order to scientifically show whether or not creatine really works. A common misconception is that creatine stimulates muscle growth. Creatine is not a steroid‚ however‚ it is a useful supplement that can help to increase muscle mass
