Not everyone is fortunate enough to live in a tropical paradise and dive all day. Most freedivers and spearfishers need to resort to cross training to keep in shape. Cross training is training with techniques from other sports to improve your diving. There are many exercises we can do on land to keep in shape. And in contrast to diving, cross training can be done no matter where you are, all year long. Longer and Deeper will teach you the most efficient exercises, how to schedule workouts and recovery, and how to keep track of your training.

Covers basic diving physiology; the pathophysiology of decompression sickness; maritime toxicology; assessment of fitness for diving; special considerations for female, elderly, and pediatric divers; diving-related problems in people with pre-existing medical conditions such as pulmonary, cardiac, and neurologic disease, and much more, with new chapters on the kinetics of intert gas, marine poisoning and intoxication, and diabetes and diving.

This text blends theoretical and scientific aspects with practical and directly applicable diving physiology and medical information. It is divided into three sections - the underwater environment, physiological responses to the underwater environment, and medical problems associated with the sport.
