The benefits of strength training not only include increased physical strength, but the ability to negate or control certain disease's while improving conditions associated with aging.
Studies have shown that initial increases in strength seen in the beginning stages of strength training programs are largely due to neural factors, even though, the process responsible for muscle growth is evident in early weeks of training. Research shows that different types of neural adaptations like enhanced coordination and increased voluntary activation of major muscles are responsible for these early increases in strength (Sale, 1988, p. S142). Muscle strength is measured by the maximum amount of torque a muscle can produce during a maximal voluntary contraction (MVC) (Duchateau, Semmler & Enoka, 2006, p. 1768). Since humans cannot completely activate a muscle voluntarily, strength training can help increase the amount of muscle a person can activate voluntarily (Gabriel, Kamen & Frost, 2006, p. 135). Some data suggest that the pattern of motor unit activation and the number of motor units activated are equally as important the frequency of activation in producing increased strength (Gabriel, Kamen & Frost, 2006, p. 136). When an individual performs specific exercises repeatedly the motor units that control the activated muscles learn to activate in a simultaneous pattern, increasing strength. This can lead to intermuscular coordination allowing muscles to distribute motor unit activation among the muscles involved in particular exercises. Changes in the capability to distribute muscle activation may be due to the ability to voluntarily activate the muscles needed for specific task (Duchateau, Semmler & Enoka, 2006, p. 1769).

Another weakness in the experimental design was that the reliability of the experiment was very low. As each test subject was only tested against each amount of prior exercise once, the impact of random errors is likely very large, which can be seen by the spread of the data on the graph. Although, this was attempted to be rectified by averaging the results of all four test subjects, it does not improve reliability too much. Conclusion: The results of this investigation indicated that a relationship between the amount of prior exercise and muscle fatigue does exist, however the results are also not conclusive enough to speculate on what the relationship is. This means that the hypothesis “If the amount of time spent performing vigorous exercise prior to the set of repetitions increases, then the physical performance (number of repetitions) will decrease” cannot be supported or rejected due to the inconclusive data.
Fatigue, decreased mobility and impaired balance from the rheumatoid and osteoarthritis pain also increases the risk of falls (Stanmore et al., 2013). Age related changes such as sarcopenia causes muscle tone and strength to decrease, especially in the lower limbs and as a result, balance and gait become impaired (Culross, 2008). These factors significantly influence the risk of falls and also affect the ability to carry out daily activities therefore, with a physiotherapists assistance, the nurse could introduce a personalised exercise regime to enhance muscle tone and strength (Culross, 2008). According to Neuberger et al (1997), exercise lessens fatigue and improves muscle tone and balance in older people. Recommending an exercise programme for Mrs Jones that incorporates strength training exercises and aerobics, could potentially improve muscle tone and strength and as a result improve mobility, balance and lessen the risk of falls (Bird, Pittaway, Cuisick, Rattray & Ahuja, 2013). The nurse could also suggest safety precautions such as advising Mrs Jones to use a mobility aid (Gooberman-Hill & Ebrahim,
Muscle fatigue is a decline in ability of a muscle to generate force within any part of the body. Muscular fatigue is a particular response when it comes to an untrained athlete that is starting an intense workout program, and the muscles of the body is not able to respond in an orderly manner as it would respond to an elite athlete. This paper will focus and provide general information about recent studies on peripheral fatigue. Peripheral fatigue is one of the sites for possible fatigue and its where neural, mechanical, or energetic events can hamper tension development. Neural fatigue is a factor of peripheral fatigue, which occurs when the nerves are unable to generate a signal and this reduces the ability of the muscle fiber to contract which is considered to be metabolic fatigue. Neural factors deals with the movement of action potential going through a process to produce a muscle contraction and when this process does not go through the proper steps then fatigue set in because the muscles will not be able to contract. Neural fatigue has two main factors which is, a shortage of...

Physiologically there are many benefits to consistent weight training. This includes muscle size, tone, and overall strength. Not only this but lifting weights has also been shown to improve psychological health as well. This is done by increasing self-esteem, conf...
Controlled increases in physical stress through progressive resistive exercise cause muscle fibers to hypertrophy and become capable of generating greater force.3 Early emphasis is on restoring joint range of motion and muscle flexibility, however, resistive exercises are not delayed. The initial emphasis of muscle loading should be on endurance, accomplished with lower loads and higher repetitions. Progressive resistive exercises are initiated at the available range and progressed to new positions as wrist range of motion returns in all planes. Both the overload principle and the SAID Principle (Specific Adaptation to Imposed Demands) are important considerations in therapeutic exercise dosing.1,3,11 Within pain tolerance, dosing progressive resistive exercises that maintain a therapeutic stress level will encourage muscle tissue hypertrophy. Finding activities that produce the correct force and repetition, without injury, is the goal of the remobilization period. Starting with low force, moderate to high repetitions, and encouraging therapeutic rest following induced stress is important to both the overload principle and the SAID Principle. Additionally, it is important to prevent dosing resistive exercises that exceed optimal stress, which may result in injury. The patient’s response to therapeutic exercise should be assessed during, immediately following,

Evidence of lifting weights can be traced back to the origins of man. As far back as cave painting and scrolls, there exists evidence of weightlifting. Initially as an expression of strength, to competition and functional training, weightlifting has carved its path through the ages. It has taken on a new role in the modern world; athletic training. With an entirely new emphasis in sports on speed, strength, and flexibility; weightlifting is more popular than ever. Unfortunately, young athletes often do more harm than good by injuring themselves lifting. When these uneducated lifters try to jump right into a program, lifting more than they should, an injury is imminent. What is overlooked, is that when weightlifting is done correctly, it has a great potential to prevent injuries instead of cause them. Understanding how the body works, using proper technique on the appropriate lifts, and participating in regular physical activity can greatly reduce the risk of athletic injuries.
Ultimately, these physiological changes result in different nutritional needs for the elderly.

Creative new training methods, developed by coaches, athletes and sport scientists, are aimed to help improve the quality and quantity of athletic training ( Kellmann, 2010, p.1). However, these methods have encountered a consistent set of barriers including overtraining ( Kellmann, 2010, p.1). Due to these barriers, the need for physical and mental recovery in athletics brought an increasing attention in practice and in research ( Kellmann, 2010, p.1).

Nutrition is an important key to learn and understand in your life while you get older. Many people do not know the proper diet and exercise to keep their body healthy and strong. Throughout this course, I have learned information on different kinds of vitamins, carbohydrates, amino acids and other helpful diets. After reading and logging my dietary log for a week it has helped me re-organize my diet and health. I have learned about how to personally manage my exercise and diet and I am seeing some good results because of what I learned from this class. I started to see what I was missing in my diet and started to know what quantity and quality was for your diet. I also took a leap into my family health history to see what I need to change
