Velocity Based Training (VBT) involves the use of technology, commonly known as a 'VBT device,' to measure the speed of barbell or human movement during exercise. Linked to a smartphone or tablet app, this device provides real-time data to coaches and athletes, enabling immediate adjustments to training or reviewing stored data for long-term programming decisions. VBT utilizes velocity to enhance training practices and can complement or replace traditional strength training methods, guiding training for speed, strength, power, or hypertrophy.

The technology allows for specific applications including, but not limited to:
The conventional practice of determining intensity using a percentage of 1RM is widely accepted but has limitations, lacking precision and objectivity. This method does not consider daily fluctuations in an individual's readiness to train or account for variations in athletes' physiological makeup.
VBT addresses these issues by quantifying intensity, enabling coaches to instantly assess multiple athletes' performances under the same relative load and identify the impact of fatigue. The linear relationship between load, intensity, and fatigue is crucial: as load increases, velocity decreases predictably. This provides a measurable variable for programming adjustments based on fatigue levels.
Velocity also serves as a marker for maximal intent, emphasizing the importance of lifting concentrically as fast as possible, irrespective of the percentage of 1RM.
Speed Timing Systems are devices or setups designed to measure and record the speed of an object, often used in sports and athletic training to assess the performance of athletes. These systems are crucial for accurately capturing the time it takes for an athlete to cover a specific distance, providing valuable and accurate data for training, performance analysis, and competition.
Traditional speed timing systems use technologies such as infrared beams, timing gates, electromagnetic fields, or video based systems. These are set up at specified distances, and when an athlete passes through, the system records the exact time, calculating the speed based on the known distance.

The technology allows for specific applications, including:
Timing systems represent the pinnacle of precision and reliability in measuring athletic performance. Utilizing sophisticated technology, such as infrared sensors and electronic signals, these systems ensure unparalleled accuracy, making them indispensable for professional sports events and high-stakes competitions.
Unlike stopwatches, timing systems provide a level of detail and sophistication that is essential for capturing split-second differences in performance, making them the preferred choice for elite athletes and coaches who demand the utmost precision in their training and competitions. With features like video integration and data storage, timing systems stand as the gold standard for those who prioritize accuracy and comprehensive performance analysis.
Aims to determine the maximum force a muscle or group of muscles can generate during a single contraction. This is typically assessed through one-repetition maximum (1RM) tests, where individuals lift the heaviest load they can manage for a specific exercise. Max strength testing is crucial for strength-focused training programs and sports requiring high force production, such as powerlifting.
Assesses an individual's ability to generate maximal power output, combining strength and speed (P=FxV). Commonly used in sports like weightlifting and sprinting, power testing often involves exercises like vertical jumps or the use of specialized equipment like force plates. It helps identify an athlete's capability to produce force quickly, a vital component in many athletic activities.
Assesses an individual's ability to perform high-intensity, short-duration activities that rely on anaerobic metabolism. Common tests include the Wingate Anaerobic Test, which measures peak and mean power during a 30-second sprint on a stationary bicycle. This type of testing is critically valuable for athletes involved in sports requiring prolonged bursts of intense efforts.
Evaluates the body's ability to sustain prolonged, moderate-to-high-intensity exercise, primarily relying on aerobic metabolism. The VO2 max test is a widely used method, measuring the maximum amount of oxygen an individual can utilize during exercise. It is a key indicator of cardiovascular fitness and endurance and is often employed in endurance sports and general fitness assessments.
