experienced by crew members during long-term space travel: muscle atrophy; loss of bone mass; and immune system changes. This paper also explores current research into preventative measures and potential treatments for these health complications. Muscle Atrophy On Earth, muscles must constantly work to support the body against the forces of gravity. However, in the zero-gravity environment of space this constant force is absent, and muscles need to work significantly less hard to perform…

The popliteus muscle and its proximal attachments: Morphological variations, functions, and clinical implications Overview: The popliteus muscle (PM) is one of the deep posterior compartment musculature of the leg and the posterolateral structure of the knee, locates in the superior aspect of the leg and consists part of the popliteal fossa’s floor my book and Ullrich (2002). It is small, flat and triangular in shape, attaches distally on the posteriomedial aspect of the tibia superior to the…

However, muscle fibers have vital physical features that develop two distinct types of fibers. The fast twitch, also known as type ii fibers, and slow-twitch fibers or type i fibers (Bidle, 2016). Muscles are also put in “compartments” a muscle compartment is known as, “a group of functionally related muscles enclosed and separated from others by connective tissue fascia.” (Sullivan & Gan, 2015). These fascias are also known as intermuscular septa. The muscle compartments also hold…

neuromuscular factors, the loss of neural input to the muscles is ongoing and a lifelong process that is irreversible. When the body loses motor units that innervate several muscle fibers, the neurons that survived attempt to “adopt” muscle fibers. The lower number of motor units functional means the individual has decreased strength and muscle atrophy. The vastus lateralis in 43 male cadavers aged 15 to 83, this study showed total number of muscle fibers was reduced by 50% between the age…

Muscular Dystrophy is a disease which leads to muscle weakness and loss of strength. This disease begins at an early age and symptoms appear during the early stages of childhood and it progressively destroys and deteriorates the muscles. Among the many types of Muscular Dystrophy, the most common and severe form is Duchenne Muscular Dystrophy (DMD). Duchenne Muscular Dystrophy is an inherited disorder and unlike other forms of Muscular Dystrophy, it is the one that develops and worsens quickly…

that over 90 percent of bodybuilders have been using an anabolic androgenic steroid. Is there an alternative muscle builder out there that is trustworthy and offers no negative side effect? Yes, there is, the new Crazy Bulk D-Bal, an all natural sports supplement. What is this Crazy Bulk D-Bal? D-bal is a 100% legal anabolic health supplement. It is guaranteed to help achieve huge muscle tissue development. And what is great about this is, it has absolutely zero negative side effects. It…

Congenital muscular dystrophy (CMD) is a muscle disorder that, even though has different ages of onset, develops most commonly at birth or in infancy. A dystrophy is a disorder that weakens and wastes away organs and tissue of the body. CMD can be characterized by hypotonia or “floppy baby”, progressive muscle weakness, and fixed joints that restrict movement. Most forms of CMD are inherited as autosomal recessive traits, affect different muscles and have different severity and inheritance…

extensively used to identify and observe the muscle disease. It is present in higher concentration in serum in reply to muscle insult and is the most delicate sign of muscle injury, which gives a precise estimate of progression of muscle injury (Bohlmeyer TJ et al.1994).It is found mainly in the myofibrils, mitochondrial membrane and the muscle cytoplasm (Bessman SP and Carpenter CL, 1985). CK is a dimer molecule, and composed of two subunits, CK-M (muscle type) and CK-B (brain type) and has…

it is the decrease in muscle size and fiber number, which affects an individual’s aerobic capacity and strength as a result of the change in muscle composition. With decreased aerobic capacity and strength in muscles, this causes detrimental effects on performing any activities or tasks that consist of running, walking, moving or carrying objects, and activities required for daily living. Muscles consist of two different types of muscle fibers: type I and type II. Type I muscle fibers are…
