Importance of Aerobic Energy System Efficiency in Tennis

Importance of Aerobic Energy System Efficiency in Tennis

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

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 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

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 but from a tennis conditioning standpoint continuous steady-state jogging...
Glycolysis Explained: How Glucose Breakdown Provides Energy

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

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: 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: 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...
