Each excessive physical and intellectual work also requires an increased food intake and rehydration. This is necessary for the reason that in the periods of significant and longer-term stress the cells are more susceptible to rapid oxidation (deterioration), they require more energy, more proteins as the building materials, as well as the water which is used for the transfer of all these nutrients.
Depending on the type of activity (light or heavy sports), the diet should be adapted in such a way that it places less burden on the digestive system, maintains the sense of satiety, but it should also provide all the requirements for additional muscle activity.
Light sports, which are also often hobbies (archery, darts, chess, billiards, golf, etc.), require in most cases only a greater mental concentration with a minimal muscle tension.
In this case it is necessary only to provide enough energy for an increased brain activity and this is most easily accomplished by eating fresh fruits rich in water and fast-releasing carbohydrates immediately before the activity (apples, tangerines, pears, peaches, etc.).
In case of more demanding sports (cycling, water polo, triathlon, football (soccer), boxing, etc.) the food must meet all the requirements for a longer and increased activity of muscles.
Before a training session or competition in these sports one should consume foods with a slow-release carbohydrates, which will continuously provide enough energy for the strain of the body.
During the training, it is best to drink an occasional small amount of low-carbonated mineral water with a little lemon.
After the training, it is first necessary to replenish the glycogen reserves in the liver and the muscles, and only then one may eat foods rich in protein.
Tensiomyography – TMG
Several years ago sports medicine was enriched with a modern diagnostic method which has been of great benefit to sports medicine doctors, but also to physiatrists, physiotherapists, strength and conditioning coaches, and even to the management of sports clubs. Thanks to Dr. Gifing’s Center, this method has recently become also available in Serbia.
TMG or tensiomiography is a noninvasive diagnostic method that provides data on the contractile properties of muscles, i.e. on their functional characteristics. It was invented by Professor S. Đorđević, a world famous sports worker and coach.
In a quick and easy way, by using direct electrical current, one is able to obtain data on the time-delayed contraction or the time that elapses between an impulse and a contraction (delayed time), the speed of contraction, the duration of contraction and the relaxation time, expressed in milliseconds.
In addition, one also obtains recommendations on any exercises and treatments necessary for a correct performance and prevention of possible injury. A special diagnostic benefit is in injured athletes, because it eliminates the impact of pain on the muscle contraction parameters.
TMG has found application in sports and medicine, as well as for research purposes.
In sport it is used for a training optimization.By screening those muscles that are the most important for a particular sport one determines by which muscle or a group of muscles requires further work (activation, power, or relaxation exercises) so that the effect could be brought to the highest level possible. The results obtained by TMG diagnostics can be used for injury prevention and to assess the current physical fitness and maximal performance of the individual.
In medicine, TMG is used in physical medicine as a diagnostics (not therapeutic) device for improving the assessment of the functional capacity of muscles during and after therapeutic procedures following an injury. It facilitates a selection of procedures and therapeutic exercises a therapist needs to make, and provides complete information on the degree of recovery. In this way it enables a timely return of athletes in the training process, thus preventing the return of injuries. A precise choice of therapeutic procedures and exercises can accelerate even the very process of rehabilitation.
The TMG software includes average benchmark values for 20 major muscles for over 20 sports, as well as the average reference values of muscles for the positions which players have in certain team sports.
TMG of the skin may be of use in selection in both top professional and recreational sports.
Amateurs are enabled to improve their training, both throughout the year and over a specific period of time in case of seasonal sports (skiing, long-distance running, extreme sports…).
