Introduction Muscular fitness is a key component to leading a healthy and active life. Muscular fitness is composed of two main aspects, muscular strength and muscular endurance. The American College of Sports Medicine (ASCM) defines muscular strength as “The ability to perform activities that require high levels of strength” and defines muscular endurance as “The ability of a muscle group to execute repeated contractions over a period of time sufficient to cause muscular fatigue” (ACSM, 2014, p. 3). Day to day activities such as lifting, carrying, and putting down objects require a certain level of functional muscular strength and muscular endurance.
According to the ACSM (2014) there is no single measure of muscular strength or muscular

Research into the validity of a modified pushup was done by Fawcett and DeBeliso (2014) and found that the modified push-up protocol from the knees to be a reliable test for arm and shoulder girdle strength and endurance when compared to a bench press test in 11-12 year old girls (p. 4). In regards to hand grip strength Bohannon (2004) did research into the use of handgrip dynamometry for assessing strength in stroke patients and found dynamometers are a reliable and practical assessment for assessing upper body strength in stroke patients (p. 263). Another clinical test on muscular strength was done by Abdul-Hameed, Rangra, Shareef, and Hussain (2012) which showed that estimated one rep maximum in the bench press, leg press, lateral pull, leg extension and seated biceps curl to be a reliable method for assessing upper and lower body strength in type 2 diabetic …show more content…
This result is classified as good based on the ACSM fitness categories for push-ups (ACSM, p. 90).
Curl-Up Test The client was able to perform 35 curl-up repetitions before failure. This result is classified as average based on the ACSM fitness categories for the partial curl-up by age and sex (ACSM, p. 90).
Estimated 1-RM For the bench press assessment the client was able to complete 5 repetitions at 185 pounds which gave an estimated 1-RM of 215 pounds. For the leg press assessment the client was able to complete 5 repetitions at 495 pounds giving an estimated 1-RM of 577 pounds. The estimates for the 1-RM were found using the formula [(0.0333 * Reps) + 1] * Weight (L. Boyd, personal communication, 2014).
YMCA Submaximal Bench Press Test The client was able to complete 41 repetitions using the YMCA submaximal bench press protocol. This result is classified as good by the fitness categories for the YMCA bench press test by age (ACSM, p. 86).
Tendo Unit After averaging the client’s three trials together, the average power was 1094, peak power was 2802.6, average velocity was 1.31, and peak velocity was 3.36.

As we have learned through our reading, most all bodies skeletal muscles are made up of primarily three types of skeletal muscle fibers, but their proportion differs depending on what action the muscles is doing. For example, type I fibers such as muscles of the neck, back, and leg have a higher proportion. According to Quinn (2014), type I muscles are slower and more effective, they tend fire a lot slower than fast twitch fibers and they fatigue at a much slower rate. Hence, slower twitch fibers are pronounced at helping athletes run marathons and bicycle for hours. Shoulder and arm muscles are not always active but are intermittent in their use; these muscles tend to have a larger amount of tension for uses in throwing and lifting. These muscles have a combination of both type I and type II B fibers. These fast twitch fibers use anaerobic metabolism to create energy and are the "classic" fast twitch muscle fibers that excel at producing quick, powerful bursts of speed. These muscles are used in events such as 100m sprint, basketball, soccer and football. Since this muscle fiber fires at such a high rate of contraction it will fatigue much faster and will not last long before needing to rest.
The muscles in our body perform various functions such as helping with blood circulation, digesting food, and moving parts of the body. The three types of muscles cells found in the body are the cardiac, smooth, and skeletal muscle cells. The purpose of this lab was to determine the relationship between muscle force and EMG activity, and to examine the effects of muscle size and muscle force. In this lab, we used iWork physiology kit to record the bursts of muscle action potentials during a muscle contraction which is also known as an electromyogram (EMG). We then used this data to compare the maximum muscle force, half-maximum muscle force, and the half- maximum fatigue time to a person’s forearm circumference (muscle size).
The focus of this paper is mechanically and automatically break down the deadlift. It focuses on the four phases of the deadlift (The lift off, pull through, the lockout, and the lowering phase) as well as the muscles involved in lifting and lowering the load. The sole purpose of the deadlift is for health and fitness. It is a core lift that works nearly every muscle in the body. Muscles from the lower and upper extremities will go through a period of flexion and extension when moving through the phases. The deadlift should be performed safely, and with proper form to avoid injury. This paper shows and demonstrates the proper form of the deadlift. There are also a number of forces acting on the load and the athlete. Gravity and external forces will be an active part of lifting the load. Images and tables are provided in the paper to better understand the movements and muscles used when performing the deadlift.

Chase Tirrel Mrs. Renner English 3 April 30, 2017 Crossfit vs. Powerlifting Why I chose My topic I chose this topic because the men in my family have always been avid lifters. My dad was a powerlifter for the majority of his 20s and 30s. When my brother was born my dad was forced to stop lifting for awhile, but as my brother got older he was able to get back into lifting. Now my brother is an avid lifter, so it just runs in the family. My passion for lifting began when I was a freshman.
Weight lifting is a broad term used to represent a vast number of actual exercises and styles. Weightlifting can be broken down into weight training, bodybuilding, fitness lifting, isometric training, resistance training, and athletic training. Although they posses similarities, often their objective separates them. Weight training generally means the pursuit of getting as strong as possible, and uses dead weight such as dumbbells and barbells. Bodybuilders have the goal to get the largest muscle mass and often times have a very small percent body fat. Fitness training or endurance training is often performed with low weight and high repetitions to build muscular endurance and general, non-athletic fitness. In isomeric training, the muscles and joints don't...
When performing manual muscle testing for shoulder flexion and abduction, PTA’s typically place their hand at the wrist verses the mid-extremity because placing their hands at the wrist increases the length of the lever thus testing the muscles ability to resist externally applied force overtime and across the bone-joint lever arm system. Shorter lever arms will provide higher testing scores when compared to using longer lever arms, thus changing the point of force application affects the length of the lever arm and therefore the muscle torque.
In lab, isometric handgrip strength was tested. Isometric strength refers to the type of force that occurs when muscles generate force, but its length remains unchanged. This can also be called a static muscle contraction. A static contraction occurs when one tries to lift an object that happens to be heavier than the force applied to the muscle or a static contraction occurs when one supports the weight of an object by holding the object steady with the elbow flexed. In both of these examples, the person feels their muscles tense but the joint does not move (Kenney, Wilmore, & Costill, 2012). Handgrip strength reflects the importance for successful performance in activities of daily living and occupational activities (Beam &
Come on you can do one more push up! When you’re in the gym you do not have the support of teammates. At crew you will not give up because of the support you have from your teammates behind you. In the gym you can just say, “Oh that set can be done another day,” and give up. We have in crew on Tuesday and Thursday a 2k-meter ergometer (erg) test to see who will be in an 8A boat, that is our eight fastest men of our crew. These are the days that you need your friends behind you pushing you so your time comes true that the couch gives you. I know this might seem harsh but when it is all over with you feel very great about the way you look and how you just pulled on the 2k test.
Ability to keep repeating an activity over a period of time, there are two types of endurance activities: 1) Aerobic Endurance These activities are usually two minutes or longer, and is the capacity of the heart and lungs to keep the body in momentum for a long duration. 2) Anaerobic Endurance Using a muscle without the use of oxygen and is usually an activity that does not exceed two minutes. Strength In gymnastics the athlete should be able to bare their own body weight in order to perform the required elements. The ability to perform a maximum muscular contraction which is extremely important, Strength though is the capability to apply force against a resistance.
This result didn’t match what I was able to do a couple of days before (45 push-ups), and so this is an example of how investing too much energy in one part of the training impeded my cardiovascular and muscular improvement during my performance of the other exercises that were part of the training. There were also some days where my form was poor or where my mind was preoccupied with other matters(ex: schoolwork, tests, etc.), and these factors also played a negative role in improving my fitness level since they prevented me from doing the best I could during my training
There are also four other health fitness components that can improve your overall fitness besides cardiovascular endurance. Muscular strength is the amount of force a muscle can produce in a single effort. Muscular endurance is the ability of the muscle to continue to perform without fatigue. Flexibility is the ability to bend and move the joints through the full range of motion. Body composition is the ratio of your body fat to the amount of lean muscles, bones, and
The muscular system is the set of all the muscles that make up the human body. It is an extensive system of muscles and nervous tissue, which is distributed all through the body. In total, the human body consists of approximately 650 muscles (Shier, Butler, Lewis, 2009). The muscular system is divided into three types of muscle: cardiac muscle, smooth muscle, and skeletal muscle (p.212).
