Book excerpt: From the elite competitor, to the weekend athlete, or as a result of everyday activities, muscle injuries are a way of life. To date, no studies have examined the effectiveness of the Alter-G G-Trainer to enhance muscle recovery from injury. Twenty-five recreationally active males between 18 and 35 were randomly assigned to one of three recovery groups: G-Trainer, treadmill running, static stretching. Recovery was performed 30 minutes, 24, 48, and 72 hours following a 45 minute downhill run. Isokinetic strength, creatine kinase, superoxide dismutase, malondialdehyde, muscle soreness and mood states were assessed at baseline, 15 minutes, 3, 24, 48, 72, and 96 hours post-exercise. Significant time effects were observed for isokinetic knee flexion/extension at 60 and 180°/second, muscle soreness (p

This book was released on 2016-05-25 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physiological responses after maximal and submaximal exercise are routinely monitored in a plethora of diseases (e.g. cardiovascular diseases, cancer, diabetes, asthma, neuromuscular disorders), and normal populations (e.g. athletes, youth, elderly), while slower or irregular post-exercise recovery usually indicates poor health and/or low fitness level. Abnormal post-exercise recovery (as assessed via blunted post-exercise heart rate dynamics) helps to predict the presence and severity of coronary artery disease, while differences in recovery outcomes in athletes might discriminate between fit and unfit individuals. Disturbances in post-exercise recovery might be due to acute or persistent changes in: (1) adaptive responses mediated by the autonomic nervous system and vasodilator substances, (2) cellular bioenergetics, and/or (3) muscular plasticity. Preliminary evidence suggests possible role of time-dependent modulation of nitric oxide synthase and adenosine receptors during post-exercise recovery, yet no molecular attributes of post-exercise recovery are revealed so far. Currently several markers of post-exercise recovery are used (e.g. heart rate measures, hormone profiles, biochemical and hematological indices); however none of them meets all criteria to make its use generally accepted as the gold standard. In addition, recent studies suggest that different pharmacological agents and dietary interventions, or manipulative actions (e.g. massage, cold-water immersion, compression garments, athletic training) administered before, during or immediately after exercise could positively affect post-exercise recovery. There is a growing interest to provide more evidence-based data concerning the effectiveness and safety of traditional and novel interventions to affect post-exercise recovery. The goals of this research topic are to critically evaluate the current advances on mechanisms and clinical implications of post-exercise recovery, and to summarize recent experimental data from interventional studies. This knowledge may help to identify the hierarchy of key mechanisms, and recognize methods to monitor and improve post-exercise recovery in both health and disease.

This book was released on 2020-05-21 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: The desire to improve muscle function and prevent overuse injuries from exercise and throughout training has led to the development of various methods to aid recovery and track readiness to perform. Ergogenic aids such as cold-water immersion, massage, and dynamic recovery procedures may have positive effects but the results of the related research remain equivocal. Furthermore, novel interventions in this scenario, like compression garments, ice vests, and photobiomodulation therapy are promising but need more evidence-based data to support their effectiveness. Similarly, to properly monitor individual physical conditioning, there is a growing interest toward unobtrusive measures to accurately represent physiological status during and/or after exercise. There are several techniques being used, such as subjective ratings of well-being, heart rate monitoring, hormonal and hematological profile assessments. However, more sensitive indexes like heart rate variability and muscle activation (voluntary and/or involuntary) are arising as attractive alternatives that may delineate physical conditioning status and readiness to perform more precisely than the aforementioned measures. The purpose of this Research Topic is to critically evaluate and summarize recent data from observational and intervention studies related to non-invasive methods designed to promote recovery and objectively monitor training status. Their association to physical performance and physiological recovery in athletes during training and competition is a major focus of this Topic.

Download or read book Exercise induced Fatigue and Recovery in the Ageing Athlete written by James William Fell and published by . This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The U.S. military's concerns about the individual combat service member's ability to avoid performance degradation, in conjunction with the need to maintain both mental and physical capabilities in highly stressful situations, have led to and interest in developing methods by which commanders can monitor the status of the combat service members in the field. This report examines appropriate biological markers, monitoring technologies currently available and in need of development, and appropriate algorithms to interpret the data obtained in order to provide information for command decisions relative to the physiological "readiness" of each combat service member. More specifically, this report also provides responses to questions posed by the military relative to monitoring the metabolic regulation during prolonged, exhaustive efforts, where nutrition/hydration and repair mechanisms may be mismatched to intakes and rest, or where specific metabolic derangements are present.

This book was released on 2009 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: A large body of evidence supports the notion that chronic stress and strain may impact healing from physical trauma. However, no evidence exists to substantiate whether chronic stress impacts recovery from exercise-induced muscle damage. In this study, a group of 31 undergraduate weight-training students completed the Perceived Stress Scale (PSS), Undergraduate Stress Survey (USQ, a measure of life event stress) a series of fitness tests and then returned 5 to 10 days later for an exhaustive resistance exercise stimulus (E-RES) workout. This workout was performed on a leg press to the cadence of a metronome to ensure a strong eccentric component of exercise. Participants were monitored for 1 hour after this workout and every day for 4 days afterwards. Hierarchical Linear Modeling (HLM) multi-level growth curve analyses demonstrated that stress measures were related to recovery from maximal resistance exercise for both functional muscular (maximal isometric force, jump height, and cycling power) and psychological (perceived energy, perceived fatigue, and soreness) outcomes. Stress was not related to outcomes immediately post-workout (except maximal cycling power) after controlling for pre-workout values. Thus, the effect of stress on recovery is not likely due to magnitude of disruption from maximal exercise. After controlling for significant covariates, including fitness and percent disruption from baseline, individuals scoring a 10 on the PSS at their first visit reached baseline 288% (2.88 times) faster than individuals who scored a 19 at this same time point. There were significant moderating effects of stress on affective responses during exercise. Feeling (pleasure/displeasure), activation (arousal), muscular pain and RPE (exertion) trajectories were moderated by stress. Exploratory analyses found that stress moderated physical recovery, but not psychological recovery in the first hour after the E-RES workout. Also, stress was related to the increase in IL-1[beta], a pro-inflammatory cytokine, in the 48 hour period after exercise for a sub-set of participants. These findings likely have important theoretical and clinical implications for those undergoing vigorous physical activity. Those experiencing chronic loads of stress and mental strain should include more rest time to ensure proper recovery.

Available in PDF, EPUB and Kindle. Book excerpt: Purpose: The purpose of the present study was to investigate indices of muscle damage and recovery in novice runners upon completion of a marathon, and compare responses in these indices when receiving carbohydrate (CHO) or carbohydrate-protein (CHO+Pro) supplementation immediately upon completion of the marathon. Methods: 10 subjects were arranged into matched-pairs based on muscle damage scores, determined by serum kinase (CK) response following an 18-mile training run. Subjects' serum CK, vastus lateralis (VL) thickness, perceived ratings of muscle soreness and mental/physical energy/fatigue, maximal isometric force of the knee extensors (MVC), and isokinetic force production of the knee extensors were measured on three occasions: prior to the marathon, 24 hours post-marathon and 72 hours postmarathon. Upon completion of the marathon, subjects were given CHO or CHO+Pro feedbags as their only source of nutrition for 2-hours post run. Feedbags were filled with foods and beverages of similar caloric content, but each item in the CHO bag contained 'low protein' (2 g of protein per serving), and each item in the CHO+Pro bag contained 'moderate protein' ( 5g of protein per serving). Results: Significant increases in CK, VL thickness, and perceived soreness were observed 24-hours post-marathon. These responses were attenuated 72 hours post-marathon in comparison to 24-hour levels, but remained significantly different from pre-marathon levels. Perceived soreness and physical/mental energy/fatigue were attenuated in the CHO+Pro group in comparison to the CHO group. Conclusions: Marathon running results in significant impairment in muscular integrity, soreness/fatigue, and muscle function for at least 72 hours post-event. CHO+Pro ingestion during the marathon influences subjective, but not biochemical, indices of post-marathon muscle recovery in comparison to CHO intake alone.
