"The intent behind energy systems is to minimise energy losses to a negligible level, as well as to ensure the efficient use of energy."
Explanation of the three energy systems used during HIIT workouts.
Energetic Pathways: understanding the three primary energy systems used during exercise: ATP-PC, glycolytic, and aerobic. This includes the biochemistry of each system and their role in energy production during HIIT.
Anaerobic Threshold: Defining the point at which lactic acid production exceeds its removal causing muscle fatigue, and explaining how this threshold can be increased through HIIT training.
Oxygen Consumption: Measuring and understanding how your body uses oxygen during exercise to estimate energy expenditure and monitor fitness levels.
Resting Metabolic Rate: Defining the amount of energy required to maintain basic bodily functions while at rest and how it can be affected by HIIT.
VO2 max: The maximum amount of oxygen the body can consume during exercise, providing an indication of aerobic power and endurance potential.
Heart Rate Training: Measuring heart rate during HIIT sessions and understanding how it relates to energy systems and fitness levels.
Interval Timing: Determining optimal duration and intensity of intervals, including active rest periods, to maximize fat burning and improve endurance.
Fuel Utilization: Understanding how energy substrates are utilized during high intensity exercise and the role of glycogen and fat as fuel sources.
Nutrition: The importance of proper nutrition for energy provision, recovery, and performance during HIIT.
Muscle Fiber Types: Exploring the different muscle types and how these affect the energy system used during HIIT.
Resistance Training: Including strength training in HIIT programs and understanding its impact on energy systems, muscle fiber types, and overall fitness.
Cross-Training: Incorporating a variety of exercises and activities in HIIT programs to maximize energy system engagement and overall fitness.
Evaluating Progress: Using various metrics and tools, such as heart rate monitors, pedometers, and fitness trackers to assess progress and make adjustments to HIIT programs for optimal results.
ATP-CP System: The ATP-CP system is the primary system used during short bursts of intense activity, such as sprints or weightlifting. It relies on stored ATP (adenosine triphosphate) and CP (creatine phosphate) for energy.
Anaerobic System: The anaerobic system is used during exercises where there is a high demand for energy in a short amount of time, such as HIIT protocols. This system produces energy without the need for oxygen and relies on carbohydrates for fuel.
Aerobic System: The aerobic system is used during exercises that are of moderate to low intensity and long duration, such as jogging or cycling. This system requires oxygen and relies on carbohydrates and fat for fuel.
Fatty Acid System: The fatty acid system is used during exercises that are of low intensity and long duration, such as walking or climbing stairs. It relies on stored fat as the primary source of energy.
Phosphagen System: The phosphagen system is used during activities that require immediate energy, such as a 100-meter sprint or a weightlifting set. It relies on ATP for energy.
Glycolytic System: The glycolytic system is used during high-intensity exercises that last for several minutes and require a large amount of energy, such as a 400-meter run or a workout that includes multiple sets of powerlifting exercises. It relies on carbohydrates for fuel.
Oxidative System: The oxidative system is used during low-intensity exercises that last for an extended period, such as a marathon or a long-distance cycling race. It relies on oxygen and fats for fuel.
Lactic Acid System: The lactic acid system is used during exercises that require a burst of energy for a short period, such as a 200-meter sprint or a set of weightlifting exercises that requires a lot of energy. It relies on carbohydrates for fuel and produces lactic acid as a byproduct.
Alactic System: The alactic system is used during exercises that require a burst of energy for a short period, such as a vertical jump or a powerlifting set. It relies on ATP for energy.
"The IPCC Fifth Assessment Report defines an energy system as 'all components related to the production, conversion, delivery, and use of energy'."
"The first two definitions allow for demand-side measures, including daylighting, retrofitted building insulation, and passive solar building design, as well as socio-economic factors, such as aspects of energy demand management and remote work."
"The third does not [allow for demand-side measures or socio-economic factors]. Neither does the third account for the informal economy in traditional biomass that is significant in many developing countries."
"The analysis of energy systems thus spans the disciplines of engineering and economics."
"Merging ideas from both areas to form a coherent description, particularly where macroeconomic dynamics are involved, is challenging."
"The concept of an energy system is evolving as new regulations, technologies, and practices enter into service."
"For example, emissions trading, the development of smart grids, and the greater use of energy demand management, respectively."
