I’ve had chance to complete an intensive cycling class today at my gym over this weekend and felt super good afterward!! Some different types of gases are argon, carbon dioxide, hydrogen,  helium, oxygen, nitrogen, nitrous oxide, propane and propylene.
If you're going to get injured in your first few months it's going to be from doing something stupid (hai guyz, watch me squat 500lbs), and in that case you're going to do something stupid whether or not you have a trainer. Each exercise starts out lasting for 30 seconds, adding 15 seconds per round up to 1 minute per exercise (3 rounds for the mathematicians). And everyone in this thread who has done a squat or a bench has been coached by someone else on proper form.
I think the point is you don't have to have your wallet raped by some dude who probably doesn't know what hes talking about. There is no reason that he can't supplement his personal training with online videos and forums.
I step into a commerical gym maybe once a year and it's always the same - absolutely pathetic form.
Also, humans naturally tend to believe everything they're doing is right - so even if he were loosing strength and atrophying doing what his trainer kept telling him to do, it'd probably be months of denial.

Among multifactorial diseases, cardiovascular diseases (CVDs) are significant due to their variable symptoms and high mortality rate accounting for one third of global deaths (Santulli, 2013). Recent studies have proved targeted packaging of miRNAs and their biogenesis components including Dicer and AGO2 in exosomes (Melo et al., 2014).
In the past decade, outstanding researches in the field of miRNA drugs have changed the face of molecular medicine. Due to their natural role in miRNA secretion and shuttling between different cells, exosomes are of great interest in miRNA therapeutics.
The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. So, for this extra-special blog day, I wanted to do a different post than I normally do: a workout recap! I know it probably doesn’t seem like it by reading this blog, but I always try to workout at least 5 times a week. But since we have a little break from school, I am at home without my bootcamp and had to make up my own workout. As you can see from the picture, I first ran an easy two miles, then did everything on the circuit list in that order. Lack of movement rescinds the good condition of a human being, whereas activities and methodical physical exercises protect and preserve it. Making aerobic exercises as a portion of your daily workout schedule is certainly the best way to keep you energetic and physically fit. Jogging and running have a great deal of influence on your body from the list of aerobic exercises. In addition to the aforementioned aerobic exercises, there are a few more exercises that you can practice either outdoors, or art gym or home. I hope that now you might have got the answer to your question ‘What are aerobic exercises?’ you can practice the above mentioned moves alternately to get the perfect and fit figure and good living and lifestyle in few months. Understanding energy systems underpins the study of exercise and the effect it has on the human body. Energy is required for all kinds of bodily processes including growth and development, repair, the transport of various substances between cells and of course, muscle contraction. To replenish the limited stores of ATP, chemical reactions add a phosphate group back to ADP to create ATP. Several energy sources or substrates are available which can be used to power the production of ATP. Creatine PhosphateCreatine phosphate is readily available to the cells and rapidly produces ATP.
ATP and creatine phosphate (also called phosphocreatine or PCr for short) make up the ATP-PCr system.
The ATP-PCr energy system can operate with or without oxygen but because it doesnt rely on the presence of oxygen it said to be anaerobic.
Glycolysis literally means the breakdown (lysis) of glucose and consists of a series of enzymatic reactions. The contribution of the fast glycolytic system increases rapidly after the initial 10 seconds of exercise.
Krebs CycleThe Krebs cycle is a complex series of chemical reactions that continues the oxidization of glucose that was started during glycolysis.
Electron Transport ChainHydrogen is carried to the electron transport chain, another series of chemical reactions, and here it combines with oxygen to form water thus preventing acidification. Beta OxidationUnlike glycolysis, the Krebs cycle and electron transport chain can metabolise fat as well as carbohydrate to produce ATP. Fat MetabolismSo to recap, the oxidative system can produce ATP through either fat (fatty acids) or carbohydrate (glucose). Protein MetabolismProtein is thought to make only a small contribution (usually no more 5%) to energy production and is often overlooked. Each of the three energy systems can generate power to different capacities and varies within individuals. In the year 2000, Noakes and colleagues (3) questioned the classical model of energy systems. Undoubtedly, fatigue is a complex subject that can result from a range of physical and psychological factors. I bet it’s slowed down now though, and your post is just the inspiration I need to get back at it.
Cycle gloves feature padding throughout the palms, where cyclists commonly get blisters and callouses. Any half-assed trainer should immediately tell him to do that - why - it will make it easier on his schedule and you don't need to be pounding away at the gym constantly.

Recently, miRNAs have been known as micromodulators in cellular communications being involved in cell signaling and microenvironment remodeling. They include a wide range of disorders connected to blood vessels and heart ranging from coronary artery disease (CAD), pulmonary arterial hypertension (PAH), and congenital heart disease to deep vein thrombosis and cerebrovascular disease.
Similar to other developmental phenomena in embryogenesis, miRNAs play critical roles in cardiovascular development and also their expression profile changes according to different pathological conditions. Exosomes are small vesicles (40–100 nm) originating from the plasma membrane or multivesicular bodies (MVBs) and are present in almost all biological fluids. Exosome shuttling is implicated in a variety of disease including cancer, CVDs or viral infections. Exosomes are flexible in size and cargo type and their non-synthetic nature potentiates them for more efficient and non-immunogenic delivery of cargo while they maintain the cargo integrity and stability. Most of CVDs can be prevented by controlling behavioral and environmental risk factors and early diagnosis and management play an important role in this regard. I wish I could give you everyone cupcakes, but if you are a regular reader of this blog, I thank you!
While eating healthy is one thing, I also like to keep in shape with some cardio and strength training.
But I made it at home with frozen bananas, fresh blueberries and strawberries, and plain greek yogurt (instead of protein powder). I'm a dessert loving Registered Dietitian (RD) with a Masters of Clinical Nutrition from UT Southwestern.
Precise activities in systematic manner help you to stay fit and healthy, which are conferred upon by regular exercise of aerobics. One of these substrates, like existing ATP, is stored inside the cell and is called creatine phosphate. It also exists in limited concentrations and it is estimated that there is only about 100g of ATP and about 120g of creatine phosphate stored in the body, mostly within the muscles. A number of factors determine which of these energy systems is chosen, such as exercise intensity for example. During the first 5 seconds of exercise regardless of intensity, the ATP-PCr is relied on almost exclusively.
Remember that the carbohydrates we eat supply the body with glucose, which can be stored as glycogen in the muscles or liver for later use.The end product of glycolysis is pyruvic acid.


This also coincides with a drop in maximal power output as the immediately available phosphogens, ATP and PCr, begin to run out.
The difference, however, is that the end product pyruvic acid is converted into a substance called acetyl coenzyme A rather than lactic acid (5). Acetyl coenzyme A enters the Krebs cycle and is broken down in to carbon dioxide and hydrogen allowing more two more ATPs to be formed. This chain, which requires the presence of oxygen, also results in 34 ATPs being formed (2). The key difference is that complete combustion of a fatty acid molecule produces significantly more acetyl coenzyme A and hydrogen (and hence ATP) compared to a glucose molecule.
However, amino acids, the building blocks of protein, can be either converted into glucose or into other intermediates used by the Krebs cycle such as acetyl coenzyme A.
Best estimates suggest that the ATP-PCR systme can generate energy at a rate of roughly 36 kcal per minute.
From very short, very intense exercise, to very light, prolonged activity, all three energy systems make a contribution however, one or two will usually predominate (5).Two factors of any activity carried out affect energy systems more than any other variable they are the intensity and duration of exercise. Their argument was based on the limitations this model has when it comes to explaining fatigue. I am following a 30 day workout schedule, day 1 calls for PPLC (Push Ups, Pull Ups, Legs, Core).
Curls and bench are pretty self explanatory, but you will need coaching if you plan on getting into stuff like power cleans.
I just don't think that personal instruction for someone new to working out is a bad thing, even if he only does it for a month. In this review, we will focus on the role of miRNAs in cardiovascular diseases (CVDs) and their reliability as diagnostic and therapeutic biomarkers in these conditions. Major CVD risk factors include family history, obesity, hypertension, diabetes mellitus, and hypercholesterolemia (Mendis et al., 2011). Since then several studies have focused on the role of these small molecules in the pathogenesis of different human diseases.
Cardiac resynchronization therapy (CRT) after heart failure helps improve the heart arrhythmia and it also affects the myocardial miRNA expression. They shuttle between neighboring cells and transfer their cargoes which can be cellular components including proteins, mRNA, and non-coding RNAs.
In CVD, exosomal transfer of miRNAs is a well-known mechanism through which, cells educate their adjacent environment in order to confront the pathological condition. Two main approaches include overexpression of downregulated miRNAs and suppression of overexpressed ones. Exosomal membranes contain certain proteins which have binding affinity to specific receptors on the surface of recipient cells. In this review, we focused on miRNAs as small non-coding RNAs involved in a variety of key cellular processes.
Cardiac fibroblast–derived microRNA passenger strand-enriched exosomes mediate cardiomyocyte hypertrophy. Adeno-associated virus (AAV) serotype 9 provides global cardiac gene transfer superior to AAV1, AAV6, AAV7, and AAV8 in the mouse and rat. Circulating MicroRNA-208b and MicroRNA-499 reflect myocardial damage in cardiovascular disease. Diagnostic and prognostic value of circulating microRNAs in patients with acute chest pain. A panel of 4 microRNAs facilitates the prediction of left ventricular contractility after acute myocardial infarction. But I’m not very creative with my workouts, because I go to a bootcamp in Dallas for my athletic needs.
My blog is here to share my passion for cooking and baking, while taking some detours into my everyday life. The old age group, if feel difficulty in performing the high influence moves such as cycling, running or dancing, then mild exercises such as brisk walk or step aerobics can be practiced. Start jogging every alternate day for fifteen minutes and gradually upsurge the time duration.
If this occurs in the presence of oxygen it is labelled aerobic metabolism or oxidative phosphorylation. Together ATP and creatine phosphate are called the high-energy phosphogens (1).FatThe other substrates that can the body can use to produce ATP include fat, carbohydrate and protein.
Recall, that ATP is rebuilt by adding a phosphate to ADP in a process called phosphorylation. ATP concentrations last only a few seconds with PCr buffering the drop in ATP for another 5-8 seconds or so. Pyruvic acid can then be either funnelled through a process called the Krebs cycle (see the Oxidative System below) or converted into lactic acid.
By about 30 seconds of sustained activity the majority of energy comes from fast glycolysis (2).At 45 seconds of sustained activity there is a second decline in power output (the first decline being after about 10 seconds).
However, the hydrogen produced in the Krebs cycle plus the hydrogen produced during glycolysis, left unchecked would cause cells to become too acidic (2).
However, because fatty acids consist of more carbon atoms than glucose, they require more oxygen for their combustion (2).So if your body is to use fat for fuel it must have sufficient oxygen supply to meet the demands of exercise. Protein may make a more significant contribution during very prolonged activity, perhaps as much as 18% of total energy requirements (1).The oxidative system as a whole is used primarily during rest and low-intensity exercise.
In particular, the general concept that fatigue develops only when the cardiovascular system's capacity to supply oxygen falls behind demand (therefore initiating anaerobic metabolism) is seen as overly simplistic.
It adds strength to the synergistic and holistic approach to sport usually found in the most successful athletes. I had more in me, but I am still dealing with injuries from the last time I jumped in to working out too fast, so I am starting slooooooow.
It's not like as his level that a personal trainer will have a detrimental effect on anything but his wallet.
CVDs comprise a variety of blood vessels and heart disorders with a high rate of morbidity and mortality worldwide. Since CVDs are hard-to-cure, several investigations have focused on different mechanisms underlying CVD in order to manage the symptoms. The primary findings emphasized on the post-transcriptional regulatory role of miRNAs through base pairing with the 3′ untranslated region (UTR) of their target mRNAs. These cargoes can perform regulatory effects and control gene expression in the recipient cells (Pegtel et al., 2010).
In heart ischemia or fibrosis, paracrine or endocrine secretion of miRNA-bearing exosomes into cardiomyocytes or active fibroblasts of the heart have been demonstrated.
These approaches have been subject to different modifications in order to improve the efficiency of delivery and less off-target effects. My bootcamp coach makes each session interesting and different from the next, so you never get bored (For me, repetitive workouts are no fun)! Most of us have a mistaken belief that the dance moves instructed in gym are all what one could think of aerobic exercises. Dancing is the best type of aerobic exercises that everyone enjoys while doing especially the young blood. You may try different actions like straight skipping, back skipping or crisscross skipping. It finishes with a brief look at some of the more recent research and subsequent new models of human energy dynamics that have been proposed as a result. However, the body stores only a small quantity of this 'energy currency' within the cells and its enough to power just a few seconds of all-out exercise (5). Fat is stored predominantly as adipose tissue throughout the body and is a substantial energy reservoir.
Traditionally, if the final product was lactic acid, the process was labelled anaerobic glycolysis and if the final product remained as pyruvate the process was labelled aerobic glycolysis.However, oxygen availability only determines the fate of the end product and is not required for the actual process of glycolysis itself.
Acetyl coenzyme A can now enter the Krebs cycle and from this point on, fat metabolism follows the same path as carbohydrate metabolism (5). If exercise is intense and the cardiovascular system is unable to supply cells with oxygen quickly enough, carbohydrate must be used to produce ATP. At the start of exercise it takes about 90 seconds for the oxidative system to produce its maximal power output and training can help to make this transition earlier (1).Beyond this point the Krebs cycle supplies the majority of energy requirements but slow glycolysis still makes a significant contribution. The oxidative system has the lowest rate of power output at about 10 kcal per minute (4).The capacity to generate power of each the three energy systems can vary with training. This necessitates introduction of novel molecular biomarkers for early detection, prevention, or treatment of these diseases. Promising tools in this regard are the oligonucleotides that mimic the endogenous miRNA or suppress the mature miRNA by sequence complementarity. In CVD, exosomes can be used as therapeutic agents, as protein delivery carriers or as gene therapy devices.


Well, the question, what are aerobic exercises can be found in this article.  Aerobic exercises ought to be taken in a much wider sense containing overall body calisthenics through different types of breathing and cardiovascular exercises.
If you attend aerobic dance classes frequently then you will observe an apparent change in your figure. Fat is less accessible for cellular metabolism as it must first be reduced from its complex form, triglyceride, to the simpler components of glycerol and free fatty acids.
In fact, oxygen availability has been shown to have little to do with which of the two end products, lactate or pyruvate is produced.
Put another way, if you run out of carbohydrate stores (as in long duration events), exercise intensity must reduce as the body switches to fat as its primary source of fuel.
In fact, slow glycolysis is an important metabolic pathway even during events lasting several hours or more (2). Exosomal membrane proteins as well as other components are usually similar to their originating cell. Addition of locked nucleic acids (LNAs) or 2′-O-methylation of the antisense oligonucleotides increases the binding specificity while cholesterol conjugation enhances the circulation time, serum stability, and cellular uptake. Understanding how it does this is the key to understanding energy systems.An ATP molecule consists of adenosine and three (tri) inorganic phosphate groups.
So although fat acts as a vast stockpile of fuel, energy release is too slow for very intense activity (5).CarbohydrateUnlike fat, carbohydrate is not stored in peripheral deposits throughout the body. Hence the terms aerobic meaning with oxygen and anaerobic meaning without oxygen become a bit misleading (5).Alternative terms that are often used are fast glycolysis if the final product is lactic acid and slow glycolysis for the process that leads to pyruvate being funnelled through the Krebs cycle. The oxidative system seems to be far more trainable although genetics play a limiting role here too. Their membranes usually contain higher levels of sphingomyelin, cholesterol and phosphatidylserine compared to their originating cells. Current achievements have portrayed a promising future for miRNA-based therapeutics although still several obstacles including their stability, renal clearance, off-target effects, inefficient endocytosis by target cells or the immunogenicity of delivery vehicles, need to be overcome. When a molecule of ATP is combined with water (a process called hydrolysis), the last phosphate group splits away and releases energy. As its name would suggest the fast glycolitic system can produce energy at a greater rate than slow glycolysis.
VO2max, or aerobic power can be increased by as much as 50% but this is usually in untrained, sedentary individuals (4).
These approaches provide insights to the future of personalized medicine for the treatment of CVDs. By regulating the fundamental cellular mechanisms such as cell differentiation, proliferation, growth, and apoptosis, miRNAs have received enormous attention for therapeutic applications. Some miRNAs can also bind to the open reading frame (ORF) of mRNA transcripts and repress translation. However, the circulatory miR-1 is not sensitive or specific enough to be known as an AMI specific biomarker since it is also affected by factors other than AMI.
Their cargo also might represent the cellular composition of RNAs and proteins or they might show a separate profile.
In CVD, some miRNA-based strategies have resulted in promising findings, including anti-miR-126 approaches that resulted in vascular smooth muscle cells and restenosis inhibition (Santulli et al., 2014b). Glycogen can be used to form ATP and in the liver it can be converted into glucose and transported to the muscles via the blood.
However, because the end product of fast glycolysis is lactic acid, it can quickly accumulate and is thought to lead to muscular fatigue (1). Huge investigations and investments have been made to bring these molecules into the clinic. Methodologies including immunoblotting, affinity extraction into magnetic beads and flow cytometry have been used to identify the protein components of exosomes. As well, recognizing tissue-specific CAF markers, the mechanisms underlying their reactivation and the miRNA signals in these processes, will potentially provide promising targets for CVD therapies. Naked oligonucleotides are less efficient due to their instability in vitro or in vivo which subject them to different nucleases.
Also, novel methodologies such as exosome-based delivery of miRNA drugs provide reliable evidence to overcome impediments such as inefficient, unspecific delivery, and immunogenic reactions. A heavy training session can deplete carbohydrate stores in the muscles and liver, as can a restriction in dietary intake. In this review, we will explain the novel diagnostic, therapeutic and prognostic approaches based on miRNAs in the field of CVDs (cardio-miRs) and the problems ahead of this research area; where we are and where we expect to be in the future. Following hypertension or cardiac infarction, cardiac hyperthrophy, and cardiac fibrosis are common diseases in which the excess amounts of extracellular matrix (ECM) proteins accumulate in cardiac tissue in order to adapt the system to the pathological conditions.
In addition to the fibroblasts in the microenvironment, exosomal transfer of signals is also used for cardiovascular protection after a disease. Lipid-based vehicles, viral systems, and cationic polymers are among the main delivery tools for miRNA-based therapeutics.
But these drugs still need investigations on different aspects of miRNA biology, their long term effects, subsequent biochemical and off-target effects and miRNA pathway analysis. Carbohydrate can release energy much more quickly than fat (5).ProteinProtein is used as a source of energy, particularly during prolonged activity, however it must first be broken down into amino acids before then being converted into glucose. They demonstrated that miRNA binding to the coding region of pluripotency genes can regulate the embryonic stem cell differentiation. For example in heart ischemia, secretory exosomes with miRNA cargos from cardiomyocytes have been shown to activate and induce the bone marrow-derived stem cells.
Each of these strategies has its own challenges and still needs improvements to address problems such as cytotoxicity, immunogenicity, and low efficiency (van Rooij and Olson, 2012).
These latter cells release the second subset of exosomes that lead to myocardial regeneration or protection (Sahoo and Losordo, 2014).
The rate at which is energy is released from the substrates is determined by a number of factors. On the other hand, some miRNAs modulate their target expression by binding to RNA-binding proteins that regulate the expression of mRNA transcripts (Eiring et al., 2010). These and other miRNAs (including miR-328) have been linked to atrial fibrillation which is mainly resulted from structural remodeling and fibrosis (Santulli et al., 2014a). Several investigations have demonstrated the selective packaging of miRNAs in exosomes and their secretion to the stroma of cells by means of signal molecules. For example, if there are large amounts of one type of fuel available, the body may rely more on this source than on others. They showed a cell-type specific tendency or mechanism for antagomir uptake by these tissues. Exosome are novel promising elements for the future of CVD treatment due to their targeted delivery capacity and their microenvironment-dependent nature. Cholesterol-based antagomirs for silencing miR-21 were also proved to inhibit cardiac fibrosis and dysfunction (Kumarswamy et al., 2012). The latter property triggers their activation in relation to the pathological microenvironment such as pH or substrate concentration.
However, further studies would be necessary to overcome obstacles such as engineering and purifying exosomes, cargo loading into them and optimizing their quality and characterization for targeted delivery.
The complexity of miRNA-mediated regulatory systems highlights the importance of these small molecules in the clinic and needs further proceeding technologies to get closer to clinical therapies. Inhibition of miR-92a results in neoangiogenic effects and functional recovery of ischemic tissues (Bonauer et al., 2009). Another promising miRNA in CVD therapeutics is miR-208 which is implicated in cardiac remodeling.
LNA-modified anti-miR-208 oligonucleotides have successfully prevented pathologically associated cardiac remodeling during diastolic heart disease (van Rooij et al., 2007). These fibroblasts affect cardiomyocytes and secrete the mediators of cardiac hypertrophy (Bang et al., 2014).
A common issue in these approaches is in vivo instability and the low homing efficiency of oligonucleotides which results in modest changes in the expression levels of the target protein. Knowing the mechanisms underlying these communications and recognizing potential strong biomarkers for diagnosis and treatment of CVDs will help us in development of future molecular therapeutics. AAV9, a specific serotype of AAVs, has tropism for myocardiocytes and enriches in the heart (Bish et al., 2008).
These strategies provide an efficient tool for cardiac gene transfer and targeted delivery of miRNA-based therapeutics.
