- [Recommendations for Testing and Assessment](https://dewittmethod.com/recommendations-for-testing-and-assessment/): Testing an assessment is essential in creating effective fitness plans and obtaining valuable information in quantifying athletes’ health and performance. Before selecting a test battery, it is critical to sit with your planning team and decide what constructs you are trying to measure. For example, are you trying to measure maximum speed, aerobic fitness, repeated sprint ability, change of direction capability, or some other constructs? Most teams are interested in a variety of these measures. Plenty of tests can be used for each of these and other constructs. You can also create your own. When selecting tests to perform, there are […]

- [Player Availability and Performance Considerations](https://dewittmethod.com/player-availability-and-performance-considerations/): Player availability and performance are separate but related concepts. Player availability reflects the decision that a player is capable of participating. Player performance, however, is related to the player’s ability to utilize his capabilities. A player could be available but not at a state where they can optimally perform.  A holistic philosophy emphasizes elevating and maximizing individual performance with evidence-based approaches. Comprehensive data assessment within the context of the individual player’s role and situation is a must. Key Elements of The DeWitt Method Philosophy Holistic Assessment Physical, neuromuscular, cognitive, and psychological readiness must be assessed for all players. Metrics include: Biomechanics Functional […]
- [Energy System Training Basics](https://dewittmethod.com/energy-system-training-basics/): When considering training strategies for developing programs for your team, it is important to remember that the body responds specifically to the energy system that is utilized. While there is some overlap in adaptations, the basic rule of thumb is that the energy system utilized will be the one that is affected by the training. In general, there are 4 energy systems that the body uses for energy. Rather than going into technical details, we can describe them in terms of duration and intensity. – Energy System 1 – Very High Intensity, Very Short Duration (less than a few seconds) – […]
- [Preseason training for Afghanistan's Women's National Soccer Team](https://dewittmethod.com/preseason-training-for-afghanistans-womens-national-soccer-team/): All coaches know that players that are prepared for preseason prior to arrival are better equipped for training loads. For that reason, fitness coaches often provide fitness programs for players to complete on their own during the off season. Of course, no plan is worth anything if not completed so there needs to be understanding between coaches and players that compliance is important. With the Afghanistan’s Women’s National Team, we are in a unique situation where players are spread all over the world (literally) and are either currently playing or are between seasons with their club teams. We have training camps […]
- [5 things to consider when planning preseason](https://dewittmethod.com/5-things-to-consider-when-planning-preseason/): Recently, I met with Randy Waldrum, Head Coach of the Houston Dash, to discuss planning for preseason training. Our preseason begins March 14, with our first league match in April 16. This gives us about 5 weeks of formal preseason training, including a week long trip to Portland and two scrimmages against college teams. As we met and stated to plan, I came up with 5 things that we considered when developing our plan. Duration of training camp The duration of the training camp in days and weeks gives you an idea of how much training your team will be able […]
- [A Coach's Choice of Words Means Everything](https://dewittmethod.com/a-coachs-choice-of-words-means-everything/): At the most recent NSCAA Convention in Baltimore, I had the opportunity to moderate roundtable discussions with Avram Grant, Stuart Pearce, and Michael O’Neill, all accomplished coaches at the club and international levels. While there were many interesting stories and experiences shared, there was one by Stuart Pearce from his career that stands out as something for coaches of all levels to contemplate. Stuart told the audience of an incident early in his playing career when he was first selected to the England National team. I am writing from memory so I may not have every word recorded perfectly, but you […]
- [Get Fit By Going Fast](https://dewittmethod.com/get-fit-by-going-fast/): Short, Fast Intervals will help you have energy for later in the game! By John De Witt Head Sports Performance Coach, Houston Dynamo Academy An excerpt from Amplified Soccer Athlete Magazine Soccer is a series of high intensity runs, like sprinting, that are separated by some lower intensity activities, like jogging, walking, or standing. The best players are the ones that can continue to perform high intensity activities later in the game. There have been numerous studies that investigate the speed and distance covered by soccer players. In a study I worked on, we found that English professional players cover on […]

Subscribe Today! Depending on your situation, you may need some extra work to be in top shape.

- [Using Time-Distance Data to Create Match-Related Fitness Sessions](https://dewittmethod.com/using-time-distance-data-to-create-match-related-fitness-sessions/): Originally posted on NSCAA.com From the Performance Soccer Conditioning newsletter and now in the Online Resource Library is NSCAA member John DeWitt’s article “Using Time-Distance Data to Create Match-Related Fitness Sessions.” The article is the first of a series based on DeWitt’s presentation from the 2014 NSCAA Convention and discusses fitness session that have the most relevance to match play. The article focuses on using data from scientific literature to inform training programs. While coaches can use data from research papers, DeWitt warns, “most of the time-distance data that are available for public use are collected in large stadiums using tracking […]

- [Fitness Basis](https://dewittmethod.com/fitness-basis/): Fitness Basis Work with me > Fitness Basis Fitness Specifics as they apply to field-based team sports Although we focus on creating fitness programs specific to soccer, it is important to realize that the specificity is not about the sport, but instead about the demands of the sport. Soccer is a field game played with few stoppages in play where athletes typically perform short high intensity bursts separated by brief periods of rest. Success often depents on 2 factors: How fast the athlete can recover between burts How long the athlete can maintain performing the high intensity actions without succumbing to fatigue. Other […]
