and to enhance muscle recovery after intensive training ( Wilson et al., 2014 ). This may lead to improved training capacity in the subsequent sessions, thereby promoting further hypertrophy and strength gains. However, not all studies show that HMB attenuates muscle damage ( Nunan et al., 2010 ), and

The purpose of this study was to profile the effect of active versus passive recovery on acid-base kinetics during multiple bouts of intense exercise. Ten males completed two exercise trials. The trials consisted of three exercise bouts to exhaustion with either a 12 min active (20% workload max) or passive recovery between bouts. Blood pH was lower in the passive (p) recovery compared to active (a) throughout the second and third recovery periods [second recovery: 7.18 ± 0.08 to 7.24 ± 0.09 (p), 7.23 ± 0.07 to 7.32 ± 0.07 (a), P < 0.05; third recovery: 7.17 ± 0.08 to 7.22 ± 0.09 (p), 7.23 ± 0.08 to 7.32 ± 0.08 (a), P < 0.05]. Exercise performance times did not differ between recovery conditions (P = 0.28). No difference was found between conditions for recovery kinetics (slope and half-time to recovery). Subsequent performance during multiple bouts of intense exercise to exhaustion may not be influenced by blood acidosis or mode of recovery.

Despite increasing participation rates in masters sport and extensive research examining age-related changes in performance, little is known about the effect of age on recovery kinetics in masters athletes. This narrative review focuses on the relationship between aging and sport participation, and the effect on both performance and recovery following an exercise bout. Current research suggests the effect of age on performance and recovery may be smaller than originally suggested and that increasing sedentary lifestyles appear to play a larger role in any observed decrements in performance and recovery in masters athletes. Currently, it appears that performance decrements are inevitable with age. However, performance capacities can be maintained through systematic physical training. Moreover, the limited current research suggests there may be an age effect on recovery kinetics following an exercise bout, although further research is required to understand the acute and chronic recovery processes in the masters athlete.

Recovery from exercise is integral to the physical training process. There is a perception among older athletes that aging negatively affects the recovery process. Plausible arguments for an impaired recovery with aging are a greater susceptibility of older muscle to exercise-induced skeletal-muscle damage and a slower repair and adaptation response. Differences in the physical activity level of the research participants are rarely considered, however. This makes it difficult to differentiate the respective roles of declining physical activity and aging on the recovery process. Furthermore, the type of exercise used to induce damage and monitor recovery is often not indicative of a normal training stimulus for athletes. This review discusses the effects of aging on skeletal-muscle damage and recovery processes and highlights the limitations of many of these studies with respect to older athletes. Future research should use an exercise intervention representative of a normal training stimulus and take the physical activity level of the participants into account.

The purpose of this study was to characterize recovery experiences of female collegiate athletes who have suffered from eating disorders. Participants were 16 collegiate female athletes who experienced recovery from an eating disorder. Participants told their recovery stories in semistructured interviews regarding factors that initiated, assisted, and hindered recovery. The most common turning point to initiate recovery was experiencing negative consequences from the eating disorder. Factors that most frequently assisted recovery included making cognitive and behavioral changes, supportive relationships, and seeking professional care. Hindering factors most commonly included lack of support from others, professional care complaints, and spending time with others with eating disorders. Results suggested that unique features of the sport environment, including coaches’ behavior and team norms, introduce either positive or negative influences on athletes as they work to recover from an eating disorder. Based on these findings, specific treatment and prevention recommendations for athletes are discussed.

During intensified phases of competition, attunement of exertion and recovery is crucial to maintain performance. Although a mismatch between coach and player perceptions of training load is demonstrated, it is unknown if these discrepancies also exist for match exertion and recovery.
To determine match exertion and subsequent recovery and to investigate the extent to which the coach is able to estimate players’ match exertion and recovery.
Rating of perceived exertion (RPE) and total quality of recovery (TQR) of 14 professional basketball players (age 26.7 ± 3.8 y, height 197.2 ± 9.1 cm, weight 100.3 ± 15.2 kg, body fat 10.3% ± 3.6%) were compared with observations of the coach. During an in-season phase of 15 matches within 6 wk, players gave RPEs after each match. TQR scores were filled out before the first training session after the match. The coach rated observed exertion (ROE) and recovery (TQ-OR) of the players.
RPE was lower than ROE (15.6 ± 2.3 and 16.1 ± 1.4; P = .029). Furthermore, TQR was lower than TQ-OR (12.7 ± 3.0 and 15.3 ± 1.3; P < .001). Correlations between coach- and player-perceived exertion and recovery were r = .25 and r = .21, respectively. For recovery within 1 d the correlation was r = .68, but for recovery after 1–2 d no association existed.
Players perceive match exertion as hard to very hard and subsequent recovery reasonable. The coach overestimates match exertion and underestimates degree of recovery. Correspondence between coach and players is thus not optimal. This mismatch potentially leads to inadequate planning of training sessions and decreases in performance during fixture congestion in basketball.

Despite suggestions that emotions influence recovery from injury, there is little research into the emotional sequelae of mild traumatic brain injury (MTBI), or “concussion,” in sport. This examination compares emotional functioning of college athletes with MTBI to that of uninjured teammates and undergraduates. A short version of the Profile of Mood States (POMS; Grove & Prapavessis, 1992) assessed baseline emotions in all groups, and serial emotional functioning in the MTBI and undergraduate groups. Whereas preinjury profiles were similar across groups, the MTBI group showed a significant postinjury spike in depression, confusion, and total mood disturbance that was not seen for the other groups. The elevated mood disturbances subsided within 3 weeks postinjury. Given that concussed athletes were highly motivated to return to play, these data could be used as a benchmark of normal emotional recovery from MTBI. Findings are discussed in relation to current literature on emotional reaction to injury and directions for future research.
