Chapter 1: understanding of endurance and its physiological foundations
Endurance in sports is the body’s ability to withstand fatigue for a long time, maintaining the necessary level of load intensity. This is a complex quality, depending on many factors, including physiological, biochemical and psychological aspects. To develop an effective strategy for increasing endurance of the athlete, it is necessary to understand the fundamental mechanisms that underlie it.
1.1. Aerobic and anaerobic energy systems:
The main source of energy for muscle activity is adenosine triphosphate (ATP). However, ATP reserves in the muscles are limited and must be constantly replenished. There are three main energy systems in the body that provide ATP resynthesis: phosphagenic system (creatine phosphate system), glycolysis (anaerobic and aerobic) and oxidative phosphorylation (aerobic metabolism).
- Phosphate system: It provides energy for short, explosive loads (for example, sprint). Creatinfosphate (KRF) breaks down, releasing energy for ATP resynthesis. This system is quickly depleted (after 10-15 seconds), but provides maximum power.
- Glycolysis: The breakdown of glucose or glycogen (the supply of glucose in the muscles and liver) for energy. Anaerobic glycolis occurs without oxygen and leads to the formation of lactate (lactic acid). It provides energy for the loads of medium intensity, but also quickly leads to fatigue due to the accumulation of lactate. Aerobic glycolysis occurs with the participation of oxygen and allows you to more effectively use glucose for the production of ATP, without the formation of lactate in significant quantities.
- Oxidative phosphorylation: The main source of energy for prolonged loads of low and medium intensity. In this process, carbohydrates, fats and proteins are used for the production of ATP in cell mitochondria. It requires oxygen and provides the largest amount of ATP, but its power is lower than that of phosphagenic system and glycolysis.
Endurance is directly related to the effectiveness of the aerobic energy system. The better the body is able to use oxygen for energy production, the longer the athlete will be able to maintain high intensity of the load without fatigue.
1.2. Oxygen transport and disposal:
Oxygen plays a key role in aerobic metabolism. The effectiveness of oxygen transport and disposal determines the body’s ability to provide muscles with oxygen necessary for energy production. The main factors affecting oxygen transport and utilization include:
- Lung function: The lungs provide the flow of oxygen from the air into the blood. The volume of the lungs, the ventilation of the lungs and the diffusion ability of the lungs affect the effectiveness of gas exchange.
- Cardiovascular system: The heart pumps blood rich in oxygen to the muscles. Cardiac emission (blood volume pumped by heart per minute) and heart rate (heart rate) affect oxygen delivery. Endurance training leads to an increase in the volume of the heart and a decrease in heart rate at rest and under load.
- Blood: Blood tolerates oxygen from lungs to muscles. Hemoglobin contained in red blood cells binds oxygen. The concentration of hemoglobin and blood volume affect the oxygen container of blood.
- Muscles: The muscles absorb oxygen from the blood and use it to produce energy in mitochondria. The quantity and function of mitochondria in muscle cells affect the ability of muscles to dispose of oxygen. Endurance training increases the amount and size of mitochondria in muscle cells.
1.3. Factors affecting fatigue:
Fatigue is a decrease in muscle ability to generate strength and maintain the desired level of load intensity. The reasons for fatigue are diverse and depend on the type and intensity of the load, as well as on the individual characteristics of the athlete. The main factors affecting fatigue include:
- Lactate accumulation: During the intensive load, anaerobic glycolysis leads to the formation of lactate. The accumulation of lactate in the muscles and blood reduces pH (increases acidity), which can disrupt the function of muscle enzymes and cause fatigue.
- Drawing of glycogen: Glycogen is the main source of energy for muscles during prolonged loads. The exhaustion of glycogen reserves in the muscles and liver leads to a decrease in blood glucose and fatigue.
- Dehydration: Loss of fluid with then leads to dehydration, which can reduce blood volume, worsen oxygen transport and increase heart rate. Dehydration can also disrupt thermoregulation and increase the risk of a thermal blow.
- Electrolyte imbalance: The loss of electrolytes (sodium, potassium, magnesium, calcium) can then disrupt the function of the muscles and nervous system, which leads to muscle cramps and fatigue.
- Central fatigue: Fatigue that occurs in the central nervous system (brain and spinal cord). The reasons for central fatigue have not been fully studied, but it is assumed that it is associated with changes in the level of neurotransmitters (serotonin, dopamine) and other factors.
- Oxidative stress: Intensive physical activity leads to an increase in the formation of free radicals, which can damage the cells and tissues of the body. Oxidative stress can contribute to fatigue and decrease in performance.
Chapter 2: Overview of dietary supplements to increase endurance
Bades (biologically active additives) can be a useful addition to the athlete’s training process and diet aimed at increasing endurance. However, it is important to remember that dietary supplements are not a replacement of a balanced diet and a proper training program. Before taking any dietary supplements, you need to consult a doctor or a sports nutritionist.
2.1. Bades that improve oxygen transport and disposal:
- Iron: Iron is an important component of hemoglobin, which transfers oxygen in the blood. Iron deficiency (iron deficiency anemia) can reduce the oxygen container of blood and lead to fatigue. Bades with iron can be useful for athletes with iron deficiency, especially for women and vegetarians. It is important to take iron only as prescribed by a doctor, since an excess of iron can be harmful to health. The recommended form of iron is chelat iron, which is better absorbed.
- Eritropoein (epto): A hormone that stimulates the production of red blood cells. Recombinant EPO (Rapo) is doping and is prohibited for use in sports. However, there are natural substances that can stimulate the production of EPO, for example, beet extract.
- Beet extract: Contains nitrates that turn into nitrogen oxide (no) in the body. No relaxes blood vessels, improves blood flow and oxygen delivery to the muscles. Numerous studies have shown that the intake of beet extract can improve endurance, especially during prolonged loads. The optimal dose is 300-600 mg of nitrates 2-3 hours before training or competition.
- L-Arginin and L-Citrullin: Amino acids, which are the predecessors of no. L-Arginine turns into no under the influence of the ne-syntase enzyme. L-Citrullin turns into arginine in the body and can be more effective for increasing the level of NO than Arginine itself. Recommended dose of L-Arginine-3-6 g per day, L-cyrollin-6-8 g per day.
- Cordyceps: Mushroom used in traditional Chinese medicine. It is believed that cordyceps improves oxygen transport and utilization, increases energy and endurance. Studies have shown that cordyceps can improve aerobic power and reduce fatigue. Recommended dose-1-3 g per day.
2.2. Bades that improve energy metabolism:
- Creatine: Increases the level of creatine phosphate in the muscles, which improves ATP resynthesis during short, explosive loads. Creatine is mainly useful for power sports, but can also be useful for athletes involved in interval training. The recommended dose is 3-5 g per day. The most studied and effective form is creatine monohydrate.
- Beta-Alanine: Amino acid that increases the level of carnosine in the muscles. Carnosine buffering lactic acid, which can reduce fatigue during intense loads. Beta-Alanin is most useful for athletes engaged in loads lasting from 1 to 4 minutes. The recommended dose is 4-6 g per day, divided into several receptions. A possible side effect is a tingling skin (paresthesia), which usually takes place over time.
- Coenzim Q10 (COQ10): Participates in the production of energy in mitochondria. COQ10 is also an antioxidant. It is believed that COQ10 can improve energy metabolism and reduce oxidative stress. The recommended dose is 100-300 mg per day.
- Fish: Sugar, which is a component of ATP. It is believed that ribosis can accelerate the restoration of ATP reserves after intense loads. Recommended dose-5-10 g per day.
- L-Carnitin: Transfers fatty acids to mitochondria for use as a source of energy. It is believed that L-carnitine can improve energy metabolism and reduce fatigue. Recommended dose-1-3 g per day. Various forms of L-carnitine (L-carnitine tartrate, acetyl-L-carnitine) can have different effects.
- Magnesium: An important mineral involved in many metabolic processes, including energy production and muscle function. Magnesium deficiency can lead to fatigue, muscle seizures and a decrease in performance. Bades with magnesium can be useful for athletes with a deficiency of magnesium. Recommended dose-200-400 mg per day. Various forms of magnesium (magnesium citrate, magnesium glycinate, magnesium oxide) have different bioavailability.
2.3. Bades that improve hydration and electrolyte balance:
- Electrolyte drinks: They contain sodium, potassium, magnesium and other electrolytes that are lost with later. Electrolyte drinks help maintain hydration and electrolyte balance during and after training.
- Sodium: The main electrolyte, lost with later. Adding sodium to drinks or food can help maintain hydration and prevent hyponatremia (low blood sodium in the blood).
- Potassium: An important electrolyte for the function of muscles and nervous system. Potassium deficiency can lead to muscle cramps and fatigue.
- Magnesium: Participates in the regulation of electrolyte balance and muscle functions.
- Coconut water: A natural source of electrolytes containing potassium, sodium, magnesium and calcium.
2.4. Dietary supplements that reduce oxidative stress:
- Vitamin C: A powerful antioxidant that protects the cells from damage by free radicals. Recommended dose-500-1000 mg per day.
- Vitamin E: An antioxidant that protects cell membranes from damage by free radicals. Recommended dose-200-400 IU per day.
- Selenium: Mineral, which is a component of antioxidant enzyme glutathioneperoxidase. Recommended dose-50-200 mcg per day.
- Alpha-lipoic acid (ALA): An antioxidant that can restore other antioxidants, such as vitamin C and vitamin E. Recommended dose is 200-600 mg per day.
- N-Acetylcistein (NAC): The predecessor of Glutation, a powerful antioxidant. The recommended dose is 600-1200 mg per day.
- Resveratrol: Polyphenol contained in red wine, grapes and berries. Resveratrol has antioxidant and anti -inflammatory properties. The recommended dose is 100-500 mg per day.
- Curcumin: The active ingredient of turmeric, has antioxidant and anti -inflammatory properties. Recommended dose-500-2000 mg per day. For better assimilation, Kurkumin should be taken with piperin (contained in black pepper).
2.5. Bades that reduce fatigue and improve recovery:
- Glutamine: Amino acid, which plays an important role in the immune system and restoration of muscles. Intensive training can reduce blood glutamine, which can weaken the immune system and slow down the restoration. Recommended dose-5-10 g per day.
- BCAA (amino acids with an extensive chain): Leucin, isolacin and valin. BCAA play an important role in protein synthesis and muscle restoration. Reception of BCAA during or after training can reduce muscle damage and accelerate recovery. Recommended dose-5-10 g per day.
- Triptofan: Amino acid, which is the predecessor of serotonin, neurotransmitter, participating in the regulation of mood, sleep and appetite. It is believed that a tripophane can improve sleep and reduce fatigue. The recommended dose is 500-1000 mg before bedtime.
- Melatonin: The hormone that regulates the cycle of sleep and wakefulness. Melatonin can improve sleep and reduce fatigue. The recommended dose is 0.5-5 mg before bedtime.
- Ginseng: A plant used in traditional Chinese medicine. It is believed that ginseng increases energy, reduces fatigue and improves cognitive functions. Recommended dose-200-400 mg per day.
- Rodiola pink: Adaptogen, which helps the body adapt to stress. It is believed that Rhodiola pink increases energy, reduces fatigue and improves cognitive functions. Recommended dose-200-600 mg per day.
2.6. Other useful dietary supplements:
- Probiotics: Useful bacteria that improve intestinal health. A healthy intestine is important for the absorption of nutrients and the immune system. Athletes often experience digestive problems due to intense training. Probiotics can help improve digestion and immune function.
- Omega-3 fatty acids: Important fats that have anti -inflammatory properties. Omega-3 fatty acids can reduce inflammation and improve recovery after training. Recommended dose-1-3 g per day. The best sources of omega-3 fatty acids are fish oil, crill oil and algae oil.
- Digestive enzymes: They help to digest food and absorb nutrients. Digestive enzymes can be useful for athletes who experience digestive problems.
