One review of studies on the effects of plyometric (explosive jump) training, or PT, suggested that plyometric training can enhance vertical jump ability and leg power for healthy individuals. This training can be as simple as drop jumps, counter-movement jumps, alternate leg bounding, and hopping. And there are PT exercises for the upper body, too! The purpose of PT is to improve your athletic performance by increasing the speed or force of muscle contraction that enables you to jump higher, run faster, throw farther, or hit harder during a game. The full article is available online from the British Journal of Sports Medicine.
In order to improve your athletic performance, you need to include strength training in your workout routine. Having a solid strength-training program can help you meet your sports and performance goals more easily by improving overall strength and delaying fatigue. Including this type of training will help you get bigger, faster, and stronger to stay a step ahead of your competitors. Your program should focus on the major muscle groups: chest, back, thighs, calves, biceps, triceps, and shoulders. Training these areas will help you become a better athlete while also improving your physique. For more about how to incorporate strength training into your routine, read the Strength Training Section of the Sports Fitness Advisor website.
The ArmyTimes reported that due to this summer’s excessive heat wave, which affected most of the United States, the Army’s physical training has been impacted by two heat-related deaths and several cases of soldiers who became ill in the heat and sought medical treatment for heat injuries. According to the article, Army officials are looking for better ways to handle the heat and keep soldiers from succumbing to it.
Heat injuries can be a cause of both illness and fatalities. The Environment: Heat section of HPRC’s website provides valuable information on policies, reports, and guidelines for surviving and performing in hot environments.
Interval training alternates high-intensity movements such as running or cycling sprints with a recovery phase that consists of rest or low-intensity movement such as walking or slow cycling. Interval training improves your cardiovascular fitness, ability to burn fat, and ability to tolerate lactic acid build-up while lowering your risk for cardiovascular disease. Overall, adaptations from interval training can lead to improvements in strength, speed, and endurance while improving your body composition. Interval training is a .
A basic interval training session could include sprinting on the straightaways (100m) of a standard track and walking the curved portion (100m). Or alternate 30-second bouts of high-intensity exercise with recovery bouts. Initially, start with rest periods longer than the work periods, and work up to equal time periods as your fitness improves. If you are out of shape, have health problems, high blood pressure, or joint problems, check with your physician before starting a high-intensity training program.

A key concern for Warfighters and athletes alike is getting injured. Continuing to train through a minor injury can turn it into a major one. Even with minor injuries, it’s important to decrease inflammation and increase the range of motion at the affected joint. Two approaches to take are RICE and ISE. Start with RICE—rest, ice, compression, and elevation—to decrease inflammation. Once inflammation is minimized, ISE—ice, stretching, and exercise—helps to increase the range of motion. Using these techniques may reduce inflammation, stiffness, weakness, and/or loss of normal function. Once pain and swelling are reduced, the next step is reconditioning. Exercises that target the area of injury should promote flexibility, endurance, speed, strength, and power while progressing gradually. The main goal of reconditioning is to efficiently decrease pain and increase range of motion. Always check with your physician to rule out more serious injury before proceeding.

Calisthenics have long been a basic component of Warfighter training to increase strength. They require minimal equipment and space and can be done virtually anywhere. Common calisthenic exercises include push-ups, pull-ups, sit-ups, dips, and squats. They help develop and maintain muscle strength, endurance, and power as well as flexibility. There are many ways to customize a calisthenic routine to achieve a specific fitness goal. For example, performing a low number of repetitions with added resistance will effectively increase muscle strength. Training with a buddy is a great way to provide resistance. Muscle endurance, on the other hand, requires a routine with a lot of repetitions. It’s recommended to include two calisthenic sessions each week on nonconsecutive days, along with other forms of physical training (e.g., plyometrics, strength training, or aerobic training). A 30-minute calisthenic session should consist of one to three exercises that involve multiple muscle groups.
