Improving aerobic energy system efficiency is important because the aerobic energy system contributes ~30% of the energy needed during tennis. The aerobic energy system can contribute to enhanced performance during a tennis match or training even though tennis is anaerobic energy system dominant. Yet steady-state jogging is an ineffective training method in optimizing aerobic energy…

Tennis Analysis: Avoid Wasting Time During Training
The tennis analysis allows coaches to design effective training programs by avoiding injuries and enhancing tennis-specific performance of their athletes. The purpose of the tennis analysis is to determine what a tennis player must be able to do in order to have success and design a training program accordingly. For example, you want to make…
Aerobic ATP Production and Energy System Efficiency
Aerobic ATP production is important for on-court tennis performance and hence understanding how the body converts foods into energy aerobically makes sense if you want to perform well. Did you know that the aerobic energy system only converts approximately 34% of the potential energy from foods into biologically usable energy? Following I will explain how…
Why Jogging Is A Waste Of Time For Tennis Conditioning
Sure, tennis players go jogging and jogging definitely has its benefits. Yet from a tennis conditioning standpoint you could use your precious time better! Many tennis coaches require their players to include jogging into their regular training program in order to maintain or enhance endurance capabilities. Jogging or Interval Training? But from a tennis conditioning…
Glycolysis Explained: How Glucose Breakdown Provides Energy
Glycolysis, the “splitting of glucose”, is the breakdown of glucose or glycogen in order to provide ATP, which occurs in the liver and in the sarcoplasm of muscle cells. Glycolysis is the energy system that predominantly provides energy for higher-intensity activities lasting 15-90 seconds and it provides a net gain of 2-3 ATP. Glycolysis Explained: Splitting of…
ATP-CP Energy System
The ATP-CP Energy System consists of two energy storage reservoirs and predominantly provides energy for high intensity activities lasting 1-10 seconds. The ATP-CP energy system consists of two energy storage reservoirs: ATP (adenosine triphosphate) Creatine Phosphate (CP) ATP The primary energy reservoir is ATP. ATP storage capacity in the body is 80g-100g and provides energy for…
Biological Energy Metabolism: ATP Production
Biological energy metabolism involves the synthesis and breakdown of adenosine triphosphate (ATP) to provide energy to do work. 3 energy systems are available. ATP (adenosine triphosphate) is the immediate source of energy for muscle cells. ATP consists of three parts: adenine ribose three linked phosphates Energy Metabolism: ATP Synthesis & Breakdown During ATP synthesis, an…
Bioenergetics: Biological Energy Transformation
Bioenergetics can be defined as the study of biological energy transformation. Get more information on how the body transforms energy from foods. The 1st law of thermodynamics states that energy is not produced or created but just transferred around. In other words, the body doesn’t produce any energy but simply transfers the energy derived from…
The Roles of Enzymes and Coenzymes
Learn more about how enzymes and coenzymes do their job, responsibility of coenzymes and factors altering enzyme activity. Talking Points You will learn about: Functions of enzymes How enzymes do their job Functions of coenzymes Responsibility of coenzymes Factors altering enzyme activity Enzymes Enzymes have two functions, (1) they control the speed of cellular chemical…
How to Pick High Protein Quality Foods
Consuming protein is essential when you want to gain muscle mass or aid the muscle recovery process after tough matches or practice session yet protein quality varies. Sure, protein supplements can be helpful yet you can also get high quality protein from your diet if you make the right food choices. On the other hand…
What is Fat?
Fat belongs to the group of nutrients called lipids and they are available in three forms. Fat is the preferred fuel source during aerobic activities. What Is Fat? Fat belongs to the group of nutrients called lipids and they are available in three forms but only one yields energy, triglycerides! Stored body fat is an…
What is Glycogen?
What is glycogen? It is the storage form of glucose and it’s being stored in the liver and in muscle cells and can be broken down quickly to provide energy! What is Glycogen? The storage form of glucose in the body is glycogen, which is a complex carbohydrate (polysaccharide) stored in animal tissue, and glycogen…
