Free Strength Machine Exercise

Using electrodes on the bicep to record the motor unit recruitment during all four conditions: control, stretching, cardio, and aerobic stretching. As shown in figure 5, the control group and the stretching are similar in the amount of EMG amplitude (mV). However, when comparing stretching with both cardio and aerobic stretching there is an increase as the intensity of the warm-up. Moreover, aerobic stretching has the highest EMG amplitude, which shows that there is motor unit cycling. Motor cycling provides a more efficient performance on the bicep because more of the muscle is being used (Widmaier, et al.,

The principles of resistance training and lifting techniques are the key to minimize the risk of injury and increase performance. To avoid injury and obtain maximum benefits from each exercise session, athletes must follow the safety guidelines of weightlifting. Before each workout session, athletes need to warm-up properly, 5 to 10 minutes of dynamic exercises, such as walking or light jogging to increase body temperature and prepare muscles, ligaments, and tendons for vigorous movements. Then, they need to perform stretching exercises for at least 5 minutes to prevent muscle pulls, strains, and sprains. At the end of each exercise session, they need to perform cool- down exercises to help the body to slowly return to a resting state. The

Lifting weights strengthens bones and tendons. It helps increase muscle volume and muscle conditioning. It allows an athlete to perform with a higher level of strength and speed. “Physically, athletes whom weight train and are in good condition will also be able to recover faster if and when an injury occurs. I see this in our setting and it is a proven fact” (Asing Interview).

It is important to familiarize yourself with the test before proceeding to do it so that you can have more accurate results (Calderia et al., 2009). In my case, I was not familiar with the 1-RM testing which may have caused my results to be skewed. I questioned if the 1-RM test was reliable for people who are untrained like me. Research has shown that 1-RM is reliable for upper and lower body muscular strength measurement in untrained clients (Hameed et al., 2012). During this lab, I found that tests such as push-up, flexed arm hang, and plank were easy for

1. Strength is operationally defined as the maximal force that can be exerted in a single effort. Using this definition, strength should be assessed using one repetition maximum (1 RM), though we often estimate strength using tests that may involve multiple repetitions.

Power is the rate at which work is performed. It has a speed component to it, unlike strength. The explosive aspect of strength is referred to as maximal muscular power and is the functional application of both strength and speed of movement (Kenney, Wilmore, & Costill, 2015). The Wingate Anaerobic Test (WAnt) has been proven to be a tool that is reliable for assessing muscular power, endurance and fatigue. A study was completed in order to determine the relationship between upper body strength and power and on the upper body anaerobicperformance. A bench press and bench press throw was used to determine upper body anaerobic performance and was measured during an arm ergometry WAnt (Lovell, Mason, Eagles, Shewring &Mclellan,2011).

Reading the results of a study which shows that daily use of a certain exercise machine resulted in an average 10 pound weight loss, there would be more I want to know about the numbers in addition to the average. Although we can never prove the equality or lack of change, we can find evidence to the contrary. (Introduction to Statistics, pg 4-1)

Free weights versus Resistance machines, and which one of these training methods is more beneficial when it comes to: Secondary stabilizing muscles, free range of motion across planes of the body, and finally the safety of the two and which one is truly safer. Although, resistance machines have been made to specifically train a muscle they are still inferior to the classic free weights: dumbbells, kettle balls, and barbells.

The origin of Weightlifting can be traced back to the beginning of recorded history  when a man's fascination with physical abilities was found among numerous ancient writings. Progressive resistance training dates back at to Ancient Greece, when wrestler Milo of Croton trained by carrying a newborn calf on his back daily until it was fully grown. Another Greek, the physician Galen, described the strength training exercises using the “halteres “ which was an early form of dumbbell in the 2nd century. “Feats” are also depicted in the Ancient Greek sculptures. The weights were generally

It is a reference technique for assessing shoulder muscle quality and distinguishing shortfalls in particular muscle groups found in certain shoulder disorders. Such measurement is a profitable apparatus for situating rehabilitation towards the affected muscle groups [11]. Isokinetic resistance training is powerful in improving muscular strength coming about because of high strengths delivered by muscles contracting at a consistent speed through the whole scope of joint movement. Isokinetic activities might be performed concentrically or eccentrically as external forces are applied to the limb [12]. (Richardson et al.,

During this investigation individuals were asked to lift the weight and lower it down and repeat the cycle at their peak performance. There is a possibility that some individuals did not perform at their peak performance at all times. This could impact the number of cycles performed each time. Therefore, this error could affect the measurements and the correlation which was concluded from the data. However this error was inevitable, but to minimise its effect shortening the period of weight lifting could be suggested. This could promote participants to actually perform at their best rate. Also, selecting a larger sample size could minimise the effect of this random error by averaging.

Athletes should develop strength and power by training the relevant muscle group(Lingenfelser, Ryan). Athletes should train for speed by running not by doing power cleans. Traditional lifting posses the same benefits without the risk of the olympic lifts(Tumminello, Nick).

Weightlifting is a power and dynamic strength game. Performance of weightlifters during competition depends on absolute and relative power output achieved by them. To enhance power and strength weightlifters, training programmes have frequent high intensity resistance exercises. (1) As volume is quantitative component of exercise, intensity is qualitative component of exercise, which is essential component of training to enhance performance.(4) Intensity describes the amount of weight lifted during resistance training. Intensity ranges from low to high and intensity prescription depends upon the athletes training status and goals. High (moderate to heavy) intensity (>80%-85% of 1RM) are required to develop maximal strength and is often used
