provides insights into current practices and perceptions of SMFT in team sports. The key findings were: (1) time efficiency and nonexhaustiveness were considered as the most important features of SMFT implementation; (2) SMFT were typically scheduled on a monthly or weekly basis, on M + 3/M − 4 and during

Older Adults’ Objectively Monitored Walking Behaviors and the Factors that Shape Them
Catrine Tudor-Locke and Stephanie Broyles
The focus of a physically active lifestyle for older adults is to preserve functional mobility and delay losses associated with decrepitude in later years. Since ambulation is of utmost importance to older adults’ mobility, the purpose of this nonexhaustive review is to consider older adults’ walking behaviors objectively captured as steps/day and the factors that shape them. Summarized evidence currently indicates that apparently healthy older adults accumulate between 2,000–9,000 steps/day and that older adults living with disabilities and/or chronic conditions average approximately 1,200–8,800 steps/day. The scientific body of objectively monitored knowledge focused on potential individual, program, and contextual factors that shape older adults’ walking behaviors expressed as steps/day (i.e., their ability to and practice of getting “out and about”) is infantile at this time. We provide a simple research agenda to spark scholarly efforts to address research gaps and opportunities in the collective knowledge base.
The Effect of Feeding during Recovery from Aerobic Exercise on Skeletal Muscle Intracellular Signaling
Paul T. Reidy, Adam R. Konopka, J. Matthew Hinkley, Miranda K. Suer, and Matthew P. Harber
We previously reported an increase in skeletal muscle protein synthesis during fasted and fed recovery from nonexhaustive aerobic exercise (Harber et al., 2010). The current study examined skeletal muscle intracellular signaling in the same subjects to further investigate mechanisms of skeletal muscle protein metabolism with and without feeding following aerobic exercise. Eight males (VO2peak: 52 ± 2 ml−1.kg−1.min−1) performed 60-min of cycle ergometry at 72 ± 1% VO2peak on two occasions in a counter-balanced design. Exercise trials differed only in the postexercise nutritional intervention: EX-FED (5kcal, 0.83g carbohydrate, 0.37g protein, 0.03g fat per kg body weight) and EX-FAST (noncaloric, isovolumic placebo) ingested immediately and one hour after exercise. Muscle biopsies were obtained from the vastus lateralis at rest (on a separate day) and two hours postexercise to assess intracellular signaling via western blotting of p70S6K1, eEF2, 4EBP1, AMPKα and p38 MAPK. p70S6K1 phosphorylation was elevated (p < .05) in EX-FED relative to REST and EX-FAST. eEF2, 4EBP1, AMPKα and p38 MAPK signaling were unaltered at 2h after exercise independent of feeding status when expressed as the ratio of phosphorylated to total protein normalized to actin. These data demonstrate that feeding after a nonexhaustive bout of aerobic exercise stimulates skeletal muscle p70S6K1 intracellular signaling favorable for promoting protein synthesis which may, as recent literature has suggested, better prepare the muscle for subsequent exercise bouts. These data provide further support into the role of feeding on mechanisms regulating muscle protein metabolism during recovery from aerobic exercise.
Monitoring Fatigue Status in Elite Team-Sport Athletes: Implications for Practice
Robin T. Thorpe, Greg Atkinson, Barry Drust, and Warren Gregson
The increase in competition demands in elite team sports over recent years has prompted much attention from researchers and practitioners to the monitoring of adaptation and fatigue in athletes. Monitoring fatigue and gaining an understanding of athlete status may also provide insights and beneficial information pertaining to player availability, injury, and illness risk. Traditional methods used to quantify recovery and fatigue in team sports, such as maximal physical-performance assessments, may not be feasible to detect variations in fatigue status throughout competitive periods. Faster, simpler, and nonexhaustive tests such as athlete self-report measures, autonomic nervous system response via heart-rate-derived indices, and to a lesser extent, jump protocols may serve as promising tools to quantify and establish fatigue status in elite team-sport athletes. The robust rationalization and precise detection of a meaningful fluctuation in these measures are of paramount importance for practitioners working alongside athletes and coaches on a daily basis. There are various methods for arriving at a minimal clinically important difference, but these have been rarely adopted by sport scientists and practitioners. The implementation of appropriate, reliable, and sensitive measures of fatigue can provide important information to key stakeholders in team-sport environments. Future research is required to investigate the sensitivity of these tools to fundamental indicators such as performance, injury, and illness.
