Exercise and Fluid Replacement

Medicine & Science in sports & Exercise

Competitive soccer engages many of the body's systems to a major extent. The musculoskeletal, nervous, immune and metabolic systems are stressed to a point where recovery strategies post-exercise become influential in preparing for the next match. Intense activity at a 7-day training camp causes participants to experience lowered concentrations of non-killer cells and T-helper cells. Two consecutive games in 24 h produce disturbances in the testosterone-cortisol ratio. When competitive schedules are congested, the recovery process should be optimized for performance capabilities to be restored to normal as soon as possible. There is evidence that glycogen stores are reduced near to depletion at the end of a soccer game and that a diet high in carbohydrates can aid recovery. Water alone is not the best means of restoring body fluids, since carbohydrate-electrolyte drinks display better intestinal absorption and reduce urine output. Some relief from muscle soreness may be achieved by means of a warm-down. Deep-water running regimens can replace conventional physical training in the days after competition. Massage, cryotherapy and alternative therapies have not been shown to be consistently effective. It is concluded that optimizing recovery post-exercise depends on a combination of factors that incorporate a consideration of individual differences and lifestyle factors. The procedures to facilitate recovery processes should start immediately the game or training finishes. Match administrators and tournament planners should consider the stressful consequences for players in periods of congested fixtures and alleviate the physiological strain as far as possible by allowing 72 h between competitive games. This frequency of competition is unlikely to be sustainable in the long term.

The use of recovery methods post‐exercise

American College of Sports Medicine roundtable on hydration and physical activity: consensus statements.

The Science of Training - Soccer: A Scientific Approach to Developing Strength, Speed and Endurance

The aim of this study was to examine if the pattern of fluid intake with a carbohydrate-electrolyte solution during 4 h recovery from prolonged, submaximal running would influence the subsequent endurance capacity. Seven well-trained athletes aged 19.8 +/- 0.3 years (mean +/- s(mean)) took part in the study, which had university ethical committee approval. They ran at 70% VO2 max on a level treadmill for 90 min (T1), or until volitional fatigue, whichever came first, on two occasions, at least 7-10 days apart. Four hours later, the subjects ran at the same speed for as long as possible (T2), as a measure of their endurance capacity. During the 4 h rehydration recovery period, the runners were allowed to drink a carbohydrate-electrolyte solution (6.9% Lucozade-Sport; sodium, 24 mmol l(-1); potassium, 2.6 mmol l(-1); calcium, 1.2 mmol l(-1); osmolality, 300 mOsm kg(-1)) ad libitum on one occasion. On the other occasion, the volume of the same fluid was prescribed from calculations of the body mass loss during T1 (2.6% of pre-exercise body mass). All subjects completed the 90 min run during T1 on both trials. However, during T2, in the prescribed intake trial, the exercise time to exhaustion was 16% longer (P< 0.05) than during T2 in the ad libitum trial (69.9 +/- 9.1 vs 60.2 +/- 10.2 min). Although there was no difference between conditions in the total volume ingested (1499 +/- 155 vs 1405 +/- 215 ml), the volume of carbohydrate-electrolyte solution ingested in the fourth hour of the rehydration recovery period was greater in the prescribed intake trial than in the ad libitum trial (258 +/- 52 vs 78 +/- 34 ml; P< 0.05). The amount of glucose ingested in this period during the prescribed intake trial was also greater than during the ad libitum trial (17.8 +/- 3.6 vs 5.4 +/- 2.4 g; P< 0.05). There was a higher blood lactate concentration at the start of T2 in the prescribed intake trial than in the ad libitum trial (1.12 +/- 0.20 vs 0.94 +/- 0.09 mmol l(-1); P< 0.05), but there were no differences in blood glucose, plasma insulin, free fatty acid concentrations or urine volume between trials. The results of this study suggest that drinking a prescribed volume of a carbohydrate-electrolyte solution after prolonged exercise, calculated to replace the body fluid losses, restores endurance capacity to a greater extent than ad libitum rehydration during 4 h of recovery, even though the total volumes ingested were the same between trials.

Influence of fluid intake pattern on short-term recovery from prolonged, submaximal running and subsequent exercise capacity.

This paper presents information gathered from helicopter airframe and engine manufacturers, as well as operators, both in Europe and Canada. It details the measures taken to prevent accidents in icing conditions through helicopter design and operating procedures. The major conclusions of the paper are that a helicopter's operating procedures change, depending on whether the route is off-shore or overland. When flying over water, there is normally a positive temperature layer above the sea, which can be used as an escape route by helicopters that encounter icing conditions. The principle types of icing that affect helicopters are engine icing and main rotor icing. Ice accretion is a gradual process, which the pilot should be able to detect from visual cues, instrument levels and handling changes. Most helicopters are not cleared for flying in any icing conditions, although nearly all their engines have basic forms of ice protection. Rotor icing directly affects the manoeuvrability and performance of the helicopter. The helicopter industry felt that snow, slush and visibility were the biggest weather problems. Although icing was a hazard, owing to the types of operations flown by helicopters, it was of less importance. The methods used to certify helicopters have been adapted from those of fixed wing aircraft, so the applicability of the airworthiness requirements, such as appendix C should be validated for helicopter operations.

Investigation into the effectiveness of certification and operational icing procedures for helicopters

A study was conducted to identify possible improvements to the current certification and operational procedures for turboprop powered aircraft operating in icing conditions. Information was gathered through a series of interviews with airframe and engine manufacturers and also, operators and aircrews in Europe and Canada. The significant issues raised during the interviews are discussed, and a number of recommendations are made for future research and development activities in die area of aircraft icing. These recommendations identify the need for improved ice protection methods, enhanced thermodynamic models in ice prediction computer codes, and development of an ice prediction probe to warn aircrew that they will soon be entering icing conditions. Recommendations also include improvements to pilot training, and the need to make weather forecasts of icing more accurate and specific.

Investigation of the certification and operational procedures for turboprop aircraft in icing

This paper presents the issues gathered from a survey carried out on helicopter airframe and engine manufacturers, and helicopter operators and aircrews, throughout Europe and Canada. The work focused on in-e ight icing and the problems of manufacturing, testing, and subsequently, operating helicopters in such conditions. Most commercially operated helicopters are not permitted to e y in known icing conditions, because they are not certie ed to do so by the aviation authority. However, during the survey it was established that owing to commercial pressures, aircrews do e y in icing conditions, using helicopters that do not have an icing clearance. In addition, there is a disparity between what the airframe manufacturers and icing specialist know are the most dangerous icing conditions, and the knowledge held by helicopter aircrews. Aircrews would like a better method of ice detection and would prefer an ice predictor, which indicates that an icing environment is approaching, rather than a detector, which tells them that they are already in icing. Furthermore, operators would like all helicopters to have a full icing clearance if there were no operational penalties. In conclusion, the industry as a whole would like to verify that the icing envelope described in the certie cation regulations is applicable for helicopters. The current parameters have been modie ed from e xed-wing aircraft, which tend to cruise at much higher altitudes and in colder, drier conditions.
