Book Description
Achieving adequate and appropriate recovery from exercise is essential in ensuring optimal performance during repeated bouts of exercise. The use of various recovery interventions has become popular in an attempt to enhance subsequent performance and accelerate post-exercise recovery. The application of various post-exercise hydrotherapy interventions has become increasingly popular, however, the majority of current recovery practices appear to be based largely on anecdotal evidence as opposed to rigorous scientific research or evidence based findings. Physiologically, various hydrotherapy protocols have been shown to affect the body via fluid shifts (interstitial to intravascular space), changes in blood flow and cardiovascular function, and reductions in oedema. The possible psychological effects of water immersion must also be considered, with athletes commonly reporting reduced sensations of fatigue and soreness following immersion. Current literature suggests both hydrostatic pressure and water temperature to be important factors influencing the success of hydrotherapy. The overall aim of the present thesis was to enhance current knowledge and understanding with regards to the physiological and performance effects of various forms of hydrotherapy, used as a post-exercise recovery intervention. Initially, four cold water immersion interventions were compared to active recovery, performed between two bouts of high intensity cycling in hot environmental conditions. Effectiveness of recovery was determined via performance in a subsequent exercise bout; in addition, core body temperature, lactate, and heart rate were recorded. The remaining studies were designed to investigate the effects of cold water immersion, hot water immersion, contrast water therapy, and passive recovery 4 (control) following exercise-induced fatigue and exercise-induced muscle damage. Rate of recovery was assessed through changes in performance, core body temperature, thigh girths, blood markers, and perceived exertion/soreness. The results of the combined studies indicate cold water immersion to be more effective than active recovery when performed immediately post-exercise between two bouts of high intensity cycling in hot environmental conditions. Additionally, both cold water immersion and contrast water therapy were effective in aiding recovery from exercise-induced fatigue and exercise-induced muscle damage. Performance variables indicated an improved maintenance or return of performance following these recovery protocols. The present studies have provided additional information to the limited knowledge base regarding the effect of post-exercise hydrotherapy interventions, specifically, the effect of such interventions on subsequent athletic performance. In conclusion, cold water immersion and contrast water therapy appear to be superior to hot water immersion, active recovery, and passive recovery following fatiguing and muscle damaging exercise. Functional and physiological recovery was enhanced following the use of these two recovery protocols.

Book Description
[Truncated abstract] Post-exercise recovery is recognised as playing an important role in athletic training programs in order to minimise fatigue levels and limit performance decrements. In recent years, post-exercise hydrotherapy techniques have been increasingly used by athletes to accelerate recovery between training sessions and competitions. The published literature suggests that both cold water immersion (CWI) and contrast water therapy (CWT) are more likely to assist recovery of performance compared with hot water immersion (HWI) or thermoneutral water immersion (TWI). However, conflicting findings exist, possibly due to the methodology used. Hydrotherapy techniques may affect recovery of performance through their influence on circulation, body temperatures, and both the musculoskeletal and neural systems. Despite the widespread use of CWT by athletes, limited literature is available on its ability to influence the recovery of performance. Furthermore, the mechanisms by which hydrotherapy techniques can assist recovery are uncertain. Therefore, the purposes of the present series of studies were to investigate the effects of post-exercise CWT on recovery of high-intensity fatiguing exercise performance, determine whether a dose-response relationship exists, and to gain a greater understanding to the mechanisms by which hydrotherapy techniques can assist recovery of performance. The first two studies of the present thesis examined the effects of performing post-exercise CWT (full body excluding head and neck, alternating 1 min in 38{486}C and 1 min in 15{486}C water) for 6, 12 and 18 min duration on recovery of high-intensity cycling and running performance 2 h later. Both studies used a randomised, counterbalanced crossover controlled design. The collective results suggested that post-exercise CWT can assist recovery of both high-intensity cycling and running performance compared with seated rest control. Specifically, performing CWT for 6 min substantially accelerated recovery of both cycling and running performance, while CWT for 12 min was only substantially beneficial for cycling performance, possibly due to the cold environmental conditions experienced by participants while running outdoors. Furthermore, CWT for 18 min had no substantial effect on recovery from either mode of exercise compared with control. Therefore, a dose-response relationship was not observed between CWT duration and recovery of either cycling or running performance...

Book Description
Abstract : There is a common belief among older athletes that intense training becomes more difficult with ageing. One of the reasons attributed to this performance limitation is an impairment of recovery processes that can prolong the time taken for the body to adequately adapt between training sessions or after competition. However, there has been limited research to address this assumption through the investigation of recovery of performance after training or competition in well-trained older athletes. This thesis reviews the literature pertaining to ageing and exercise with particular reference to athletic performance, muscle damage and muscle repair/regeneration, with the intention of exploring the effects of ageing on training, overload and recovery from exercise in the well-trained ageing athlete. Two arguments are presented for an impaired recovery from training and competition in the older athlete. The first is that muscle damage after exercise is greater in the older athlete, and the second is that tissue repair is slower, both factors potentially prolonging recovery duration. The importance of adequate nutrition for recovery in athletes is recognised and discussed in regard to optimising recovery and to identify any specific dietary requirements or limitations that might be unique to the ageing athlete. Therefore, the aims of this thesis were to: 1. describe the common beliefs and practices amongst athletes regarding ageing and recovery from intense training and competition demands, 2. assess and compare the nutrient intake of young and ageing athletes via the completion of diet records, 3. quantify any differences between well-trained young and ageing athletes, that were matched for fitness and training variables, in their performance impairment, perceived physical impairment or rate of recovery after intense exercise. In addressing these aims four studies are presented. The first utilised a brief questionnaire administered as a method of subject recruitment for future studies. Thirty six athletes under 30 years of age (24 3 years) and sixty four athletes aged 30 years and above (41 8 years) provided responses to a series of questions pertaining to training history, current training activities, post exercise symptoms of fatigue, perception of recovery duration, and the use of recovery strategies. Results indicated that there were significant differences (p less than 0.05) between the young and older groups for training frequency (9 3 vs. 7 3 sessions per week), training volume (17 8 vs. 11 5 hours per week) and recovery duration (10 9 vs. 16 14 hours). There was also a significant positive correlation between recovery duration and training history (R=0.28, p less than 0.01). The majority of athletes surveyed indicated that they used specific strategies to promote recovery (76%). The second study compared the nutrient intake of young and veteran athletes (veteran: up to 35 years). The purpose of the dietary analysis was to establish if any apparent differences in recovery attributed to ageing could be a result of differing nutritional practices. Three-day diet record data from 13 young (24.0 ł 4.8 years) and 16 veteran (43.8 ł 5.0 years) athletes were collected and compared for differences in nutrient intake that might contribute to impaired recovery from exercise. Diet records were analysed by a qualified dietitian using the dietary analysis software Food Works (Xyris Software, Highgate Hill, Australia). Physical activity levels were assessed using the Baecke physical activity questionnaire. Energy expenditure was also estimated using the equations of Schofield and Harris-Benedict. The results indicated that there were no significant differences between young and veteran athletes for overall energy intake. However, the veteran athletes had a significantly higher percentage of daily energy intake from fat than the young athletes (35 5 vs. 29 6 g.day-1; p less than 0.05). The mean dietary intake of CHO for both age groups was substantially lower than the recommended guidelines for endurance athletes. The third and fourth studies compared measures/markers of recovery in nine young (23.7 ł 4.8 years) and nine veteran (44.3 ł 5.4 years) cyclists and triathletes that were matched for training and performance. Recovery was measured over three days (T1 to T3) of intense exercise that replicated heavy training and/or competition demands. Functional performance measures included a progressive maximal test, thirty-minute time trial performance (TT30), leg power (countermovement jump), leg strength (maximal voluntary isometric contraction), sprint cycling performance (10 second sprint) and analysis of blood markers associated with exercise induced muscle damage (creatine kinase, lactate dehydrogenase). Perceptual and report of recovery (psychological recovery) was assessed using verbally anchored Visual Analogue Scales used to measure motivation, muscle soreness (SOR), ratings of fatigue (FAT) and the total quality recovery scale (TQR). For the measures of functional performance there were no significant differences between the two age groups. Both groups maintained their time trial performance over the three days of intense endurance exercise. The average height jumped in the countermovement jump decreased slightly (2.6%, p less than 0.05) over the three days. There was also a significant decrease in average heart rate during the TT30 over the three days (̃3 b.min-1) for both groups. In response to the testing protocols serum CK activity was significantly elevated for both age groups on days two and three (combined age data: T1- 122 ł 43, T2- 178 ł 90, T3- 166 ł 87, p less than 0.05). For the perception and report of soreness, fatigue and recovery, non-parametric statistics indicated that the veteran group reported a significant (P less than 0.05) change in SOR (6.2 ł 2.6 to 28.2 ł 14.1), FAT (1.7 ł 1.2 to 2.2 ł 0.09), and TQR (15.8 ł 2.5 to 13.8 ł 2.1) over the T1 to T3, while these changes in the young group were non-significant (SOR: 15.5 ł 15.5 to 24.2 ł 17.1, FAT: 1.7 ł 1.1 to 2.2 ł 0.9 and TQR: 16.3 ł 2.6 to 15.1 ł 2.9). The change in muscle soreness was significantly (p less than 0.05) greater in the veteran group than in the young group (Veteran, 22 ł 14; Young, 9 ł 12). This investigation has provided the first comprehensive description of recovery from exercise in well-trained veteran endurance athletes. The common perception of a delayed recovery with ageing was supported by the longer reported duration required to recover between intense training and competition in athletes 30 years and older. This slower recovery does not appear to be due to major dietary differences between young and veteran athletes. In contrast to the perception of slower recovery repeated days of intense endurance cycling exercise was similarly tolerated by young and veteran athletes with respect to performance. However, there is a greater change in the perception of, muscle soreness and significant changes in fatigue and recovery in veteran athletes. This finding has implications for the effective monitoring of training load in the older athlete.

Book Description
Participation in a physically demanding team sport, such as Australian football (AF), can result in post-exercise physical performance decrements as well as increases in psychometric measures, muscle damage and inflammation. The use of both cold water immersion (CWI) and contrast water therapy (CWT) as a means of post-exercise recovery is becoming more prevalent in the team sport environment. Both modalities are utilised in an attempt to enhance physical performance recovery while reducing perceived muscle soreness and fatigue. Although increasing in popularity, conflicting evidence exists regarding their effectiveness. Comparisons within the same team sport population are lacking, while little information on the efficacy of either intervention exists in AF. Therefore, the effects of a single 14 min exposure of both CWI and CWT on restoring repeat 20 m sprint time, jump performance and psychometric measures was investigated following AF training (Study 1) and an AF match (Study 2). The effects of both modalities post-match on moderating the appearance of markers of muscle damage and inflammation was also investigated (Study 3). Australian football training and match participation reduced repeat sprint, countermovement and squat jump performance and increased perceptions of fatigue and muscle soreness. Match participation also greatly increased inflammatory and muscle damage markers. Both CWI and CWT were more successful than a passive recovery at attenuating decrements in physical performance and reducing exercise induced increases muscle soreness, fatigue and markers of muscle damage, with CWI being the most effective. Neither CWI nor CWT altered the postexercise inflammatory response and therefore most likely had no effect on blunting the inflammatory pathways involved in muscle repair. Results demonstrate that AF participation leads to post-exercise declines in physical performance, an acute phase inflammatory response, muscle damage and heightened perceptions of soreness and fatigue. It was established that in well trained AF players, both modalities were more effective at attenuating these changes than a passive recovery with CWI being more effective. These findings add to the body of knowledge regarding the use and efficacy of CWI and CWT in team sport and would be of benefit to team sport athletes/coaches in decreasing any confusion regarding their use and in helping them to determine the best modality for their recovery needs.
