Improving Running Economy

Running Improving Running Economyis a very popular and effective method to increase endurance and improve health. An increasing number of people participate in large running events such as a Marathon, Half-Marathon or other distances. Aside from oxygen uptake (VO2max) running economy is one of the most important variables that influences how well you perform at running events. This article will tell you why and how you should be improving your running economy.

Monitoring Exercise Intensity

Exercise intensityMonitoring exercise intensity is one of the most important factors that determines if your workout is effective or not. Whether your goal is to lose weight or improve your endurance, you should keep track of your exercise intensity when you want results. For cardio training the most accurate way to measure exercise intensity is the oxygen uptake. However this requires expensive and often cumbersome equipment to be practical in everyday training. Fortunately there are three other ways that can be used effectively during your workout.

Top 5 Static stretching fables

 StaticStatic stretching fables stretching is the most performed form of stretching. For most people it is the only form of stretching they know and its simply synonymous with stretching. Static stretching is performed by all sorts of athletes, from those just starting to run after years of inactivity to the most elite athletes in almost all sports. It is often recommended by (personal) trainers and coaches for several reasons, all of which have been disproven by scientific research. Or in other words are plain nonsense. This article will tell you which supposed effects are static stretching fables.

Effects of Amino Acid Supplementation and Resistance Exercise on Muscle Adaptation

Abstract

The purpose of this article is to investigate and evaluate the effects of amino acid supplementation in combination with resistance exercise on muscle hypertrophy and strength. The mechanisms of different processes in protein turnover on which amino acid supplementation has an effect are explored. Amino acid supplementation in combination with resistance exercise increases serum IGF-1 concentrations, decreases testosterone concentrations and leaves myostatin expression unchanged. These processes increase mRNA translation, which results in an increase in hypertrophy and, if resistance training intensity is high enough, in increases in strength. In the end it seems that although not all effects of amino acid supplementation are positive for protein synthesis, the net effect is an increase in protein synthesis.

Dangers of too much belly fat

Dangers of too much belly fat

More than 60% of adults are currentlyToo much visceral fat overweight and the number of people who suffer from lifestyle related disorders such as cardiovascular disease, diabetes and is rising rapidly. To make matters worse, in the western world these diseases are among the leading causes of death. Being overweight or obese is often a central factor in developing diabetes, high blood pressure or cardiovascular disease and both body mass index (BMI) and body composition give a good indication to the risk of developing these disorders. In fact the BMI norms were originally developed based on research that found a connection between body weight relative to body height and risk of developing disease.

Dumbbells vs Barbells: Dumbbell Shoulder Press vs Barbell Shoulder Press

Dumbbell Shoulder Press vs Barbell Shoulder Press

Barbells vs Dumbbells

In the first article in the Barbell vs. Dumbbell series we compared the Bench Press with the Dumbbell Press. In this second article in the Barbell vs. Dumbbell series we analyze which variant is the most effective for muscle growth for shoulder muscles: The Military Press (Barbell Shoulder Press) or the Dumbbell Shoulder Press. The Military Press is another classic barbell exercise and an essential part of a weightlifters’ training in which a barbell is pressed from just above shoulder height to above the head with outstretched arms. The Military press is performed while standing, although it is possible to perform it seated and decrease stability requirements. The Dumbbell Shoulder Press is a variant of this exercise but is usually performed while seated. It is perfectly possible to perform this exercise while standing however. Both exercises target the deltoid and triceps brachii muscles. Since both these exercises can be done both seated and standing, the effects of posture and which is more effective will be discussed as well.

For those who want to increase the size of their chest muscles it is important to train all different parts of the pectoralis major. This article reviews which exercises target the different parts of the chest muscle best. In addition, muscle activity of assisting (synergistic) muscles will be reviewed as well.

Tabata training

What is Tabata Training?

Tabata training is a form of high intensity interval training first investigated by the Japanese scientist Professor Izumi Tabata. The first few studies were primarily aimed at enhancing sport performance in athletes using short interval training sessions on a stationary bicycle. Every training consisted of eight 20 second sprints on a stationary bicycle at very high intensity alternated with resting periods of 10 seconds. After the training period endurance (maximal oxygen uptake) increased to a larger extend in the Tabata interval training group, despite the workouts being much shorter, compared with a group that performed regular modrate intensity endurance training for 60 minutes each training.1 Ever since that study, the Tabata interval training protocol has become very popular and is increasingly used to help (professional) athletes get fitter and help people lose weight.

Muscle soreness: Essential for training results?

Muscle soreness often occurs after very intensive workouts or unknown movements. Muscle soreness It is therefore often seen as an indication of an effective workout and by some even as necessary for adaptations in muscle tissue. For this reason many fitness enthusiasts strive to achieve muscle soreness after their workouts, despite the discomforts this will give in daily life. But can muscle soreness be used as an indication for an effective workout and is muscle soreness essential for training results or is it a sign of overload?

The pro’s and cons of different stretching methods

Stretching is often done as a form of warming up before exercise,Stretching methods to decrease the risk of sports injury or to increase the range of motion of muscles and joints. Although there are several different stretching methods, the most performed method is static stretching. Other forms of stretching are balistic stretching, dynamic stretching and proprioceptive neuromuscular facilitation (PNF). This article gives an overview of these different stretching methods and their specific advantages and disadvantages and advice when to use them.

Fitness and exercise and multiple sclerosis

Introduction

Multiple Sclerosis (MS) is an inflammatory condition which damages myelin sheats around the axons of the brain and spinal cord. The myelin sheath improves nerve conduction velocity and is crucial for communication between nerve cells. Damage or demyelination decreases nerve function which can lead to muscle weakness, muscle spasm and ataxia.1 These are some of the more common symptoms of MS, but is can take many different forms.1,2 Scientists have not found the cause of MS, however more evidence is pointing towards that MS is an auto-immune disorder.1 Patients suffering from MS are usually treated with medicines aimed at improving symptoms and physiotherapy or exercise therapy.3,4 The aim of these therapies is maintaining functioning, such as performing everyday tasks.5 Recently more research is performed to the effects of physical training on MS symptoms,4 however a complete overview is still lacking. The aim of this article is to review the effects of different forms of training on MS symptoms.

Fitness and depression

By: Meike de JongDepression

Introduction

Almost everyone knows someone who is suffering from a mild or more serious form of depression. A depression is a serious psychological mood disorder which is characterised by insomnia, fatigue, change in appetite and a state of low mood.1 Unfortunately the number of people suffering from depression is expected to increase by as much as 10%.2 Treatment of depression usually consists of medication (antidepressants) and psychotherapy. In addition other therapy forms such as light therapy and alternative treatments are often used.3

Fitness as treatment for cancer

Abstract

Cancer is a serious illness which affects many people in their lives and currently causes most deaths in the western world. Although cancer is primarily treated by chemotherapy and radiotherapy, physical activity and/or exercise has positive effects on therapy related fatigue, daily functioning, quality of life, muscle strength, physical fitness and risk of developing secondary cancer in (ex)-cancer patients. In addition, fitness as treatment for cancer positively affects inflammatory mediating factors, which are related to developing and maintaining cancer.. Moreover it has been shown that the risk of developing cancer decreases as a result of training. These effects strongly depend on training intensity, training volume and how well exercise guidelines are followed.

Fitness as treatment for high blood pressure

High blood pressure, also known as hypertensionHeart is the main risk factor in developing cardiovascular disease, heart failure and can even lead to a heart attack. Hypertension is diagnosed when systolic pressure is >140mmHg and/or diastolic pressure is >90mmHg when there are no co morbidities such as diabetes or kidney diseases. A systolic and diastolic pressure of <120 and <80 is considered a healthy blood pressure independent of age. Hypertension can have many causes, but often the cause can not be determined, which is known as primary or essential hypertension. Hypertension is usually treated with medicine like diuretics, beta blockers or ACE-inhibitors. However recently another form of treatment is recommended by doctors, which is physical activity and training. This article reviews literature investigating the effects of fitness as treatment for high blood pressure. Studies on cardiovascular of resistance exercise in people with hypertension will be evaluated and determined whether these training forms have a place in the treatment of hypertension.

Strength training to lose fat

Many people train in a gym or fitness center to lose weightStrength training to lose fat or improve their looks. It is often thought that the best way to lose weight by burning fat is to perform cardio training. Outside the fitness centers, many people can be seen running or cycling ot lose weight. Although cardiovascular exercise is an excellent method to burn a lot of calories, especially when performed at the right intensity, strength training or resistance exercise is often overlooked. Strength training to lose fat is not done by many. This however, is a missed oportunity. Resistance exercise can help greatly in burning fat and improving body composition, because it increases resting metabolic rate.

Core stability training on unstable devices

In many fitness centers people perform core stabilityBosu core stability training training to strengthen the so-called ‘core’ on unstable surfaces. Well known examples of these are the Bosu Balance Trainer, Bosu Ball (Both Sides Up) and the Swiss Ball. The core is usually defined as the region of the body which is made up by the abdominal wall, pelvic floor, the lower back and the diafragm. This region plays an important role in stabilizing the spine during movements and is therefore crucial in sports performance. In addition, a large percentage of low back pain cases are caused by badly functioning core muscles. The idea behind training on an instable surface is that more muscles are active to stabilize the body during any given movement compared with performing the same movement on a stable surface. This would result in improving intermuscular coordination and therfore reduce complaints caused by weak or badly cooperating muscles. Moreover it could result in better training results and in many sport activities improve performance. This article aims to review the scientific evidence for core stability training on unstable surfaces as a means to treat low back pain and as functional training to enhance sports performance.
