Background: Dietary intakes can impact an athletes health and performance. Although evidence exists about what an athlete should eat, an athlete's nutritional intake is influenced by many factors. The limited research available suggests the main barriers preventing optimal nutritional intakes reported by athletes are lack of time, food accessibility, poor cooking skills, costs, taste, and time spent in “off-season.” Although these factors have been shown to influence dietary intake they remain relatively unexplored in Rugby Union. This study aimed to describe the nutritional influences on dietary intake amongst Rugby Union player's.Methods: This was a qualitative study utilising in person individual interviews with all participants. Participants were Rugby Union players (n = 30) for either a Super Rugby franchise or one of their development squads in New Zealand. Participant's undertook recorded face to face interviews, which were later transcribed. A thematic approach was used to code the transcripts by the primary coder and the themes were subsequently evaluated by the research team.Results: Childhood upbringing, organisational skills, time and food security also emerged as barriers. Body composition and sport nutrition knowledge emerged as both barriers and enablers to nutritional intake. Influence on performance was an enabler to optimal dietary intake. Fully professional rugby players have access to dietitians, whereas development and semi-professional rugby players only have limited if any access, and they were more likely to seek nutritional information via social media.Conclusion: This study suggests a need for greater nutrition education at developmental levels with an emphasis on affordable food choices, meal planning and skills for interpreting online nutrition information.

Sleep Parameters

This study investigated the acute effect of exercise on sleep outcomes among healthy older women by comparing days with structured exercise versus days without structured exercise during 4 months of exercise training. Participants (n = 51) in this study had wrist-worn actigraphic sleep data available following at least 3 days with structured exercise and 3 days without structured exercise at mid-intervention and at the end of intervention. The exercise intervention was treadmill walking. Multilevel models were used to examine whether structured exercise impacted sleep outcomes during the corresponding night. Overall, 1,362 nights of data were included in the analyses. In unadjusted and adjusted models, bedtimes were significantly earlier on evenings following an acute bout of structured exercise than on evenings without structured exercise. No other sleep parameters differed between exercise and nonexercise days. Understanding the effects of exercise on sleep in this understudied population may help to improve their overall sleep quality.

PURPOSE: To evaluate the effect of a purpose-designed exercise program on performance-related musculoskeletal disorders (PRMDs) and associated risk factors in a sample of professional orchestral musicians. METHODS: A 10-week exercise program was made available to full-time musicians employed by the eight premier symphony orchestras of Australia. Questionnaires were administered before, immediately after (T1), and 6 months after interventions (T2) containing questions relating to change in frequency and severity of PRMDs, ratings of perceived exertion (RPE) during rehearsal, private practice, and performance, as well as nine performance-related factors. Participants were also asked to rate whether these performance-related factors affected their overall playing capacity during different playing situations. A comparative control group of musicians had no intervention and completed a modified questionnaire at the same time points. RESULTS: Exercise participants (n=30) reported a reduction in frequency (p<0.05) and severity (p<0.05) of PRMDs at T1 but not at T2 compared to controls (n=23). The exercise group reported a significant improvement in RPE during private practice at T1 (p<0.01) and T2 (p<0.01), but not during rehearsal and performance. At T1, the intervention was rated to be moderately to highly effective for three performance-related factors: strengthening muscles that support playing, learning techniques that support playing, and posture. Further, participants reported an intervention effect on overall playing capacity during rehearsal at T1 and T2. CONCLUSIONS: A tailored exercise program for musicians was effective at managing PRMDs, especially in reducing the frequency and severity of PRMDs. Physical therapy exercises should be considered in modifying performance-related factors that have been reported to be predictors of PRMDs.

Long Distance Race

Long-distance race car drivers are classified as athletes. The sport is physically and mentally demanding, requiring long hours of practice. Therefore, optimal dietary intake is essential for health and performance of the athlete. The aim of the study was to evaluate dietary intake and to compare the data with dietary recommendations for athletes and for the general adult population according to the German Nutrition Society (DGE). A 24-h dietary recall during a competition preparation phase was obtained from 16 male race car drivers (28.3 ± 6.1 years, body mass index (BMI) of 22.9 ± 2.3 kg/m2). The mean intake of energy, nutrients, water and alcohol was recorded. The mean energy, vitamin B2, vitamin E, folate, fiber, calcium, water and alcohol intake were 2124 ± 814 kcal/day, 1.3 ± 0.5 mg/day, 12.5 ± 9.5 mg/day, 231.0 ± 90.9 ug/day, 21.4 ± 9.4 g/day, 1104 ± 764 mg/day, 3309 ± 1522 mL/day and 0.8 ± 2.5 mL/day respectively. Our study indicated that many of the nutrients studied, including energy and carbohydrate, were below the recommended dietary intake for both athletes and the DGE.

The objective of this study was to evaluate the effect of inclusion of palm kernel cake in the diet on dietary intake and digestibility and performance of lactating crossbred cows. Twelve Holstein × Zebu crossbred cows were distributed in three 4 × 4 Latin squares with the following treatments: control (no inclusion of palm kernel cake in the diet); inclusion of 50 g of palm kernel cake kg-1 in the total dry matter, 100 g of palm kernel cake kg-1 in the total dry matter, and 150 g of palm kernel cake kg-1 in the total dry matter. There was no effect of palm kernel cake on the intakes of dry matter, corrected neutral detergent fiber, non-fibrous carbohydrates, and total digestible nutrients. The intakes of crude protein and ether extract increased linearly. Inclusion of palm kernel cake in the diet did not influence the digestibility coefficients of dry matter, protein, ether extract, and non-fibrous carbohydrates, or milk production, feed efficiency, and body weight change. Fat-corrected milk yield increased linearly with the addition of palm kernel cake. Inclusion of up to 150 g of palm kernel cake in diets did not influence the dietary intake and performance of lactating cows or the composition of their milk.

Recent evidence has indicated that chewing gum can enhance attention, as well as promoting well-being and work performance. Four studies (two experiments and two intervention studies) examined the robustness of and mechanisms for these effects. Study 1 investigated the acute effect of gum on mood in the absence of task performance. Study 2 examined the effect of rate and force of chewing on mood and attention performance. Study 3 assessed the effects of chewing gum during one working day on well-being and performance, as well as postwork mood and cognitive performance. In Study 4, performance and well-being were reported throughout the workday and at the end of the day, and heart rate and cortisol were measured. Under experimental conditions, gum was associated with higher alertness regardless of whether performance tasks were completed and altered sustained attention. Rate of chewing and subjective force of chewing did not alter mood but had some limited effects on attention. Chewing gum during the workday was associated with higher productivity and fewer cognitive problems, raised cortisol levels in the morning, and did not affect heart rate. The results emphasise that chewing gum can attenuate reductions in alertness, suggesting that chewing gum enhances worker performance.

This study was mainly designed to contrast the Individual Zones of Optimal Functioning (IZOF) emotion model and the performance profiling approach in predicting performance of rugby players based on normative, individualized, situational, and relatively stable characteristics. Pregame assessments were accomplished in 33 male Italian rugby players of a top-level team over a whole championship, and individual interviews were conducted at the end of the season. Performance differentiation and discrimination between athletes were reached on relatively stable qualities (i.e., constructs), according to predictions within the performance profile framework. Study findings also revealed that emotions modify widely during the game because of external events (e.g., behaviors of teammates or opponents) or individual behaviors (e.g., individual faults). In conclusion, findings add support to the contention that extending the IZOF model to other physical or performance related components would require situational rather than relatively stable qualities. On the other hand, the concept of zones extended to constructs seems beneficial for practical purposes.
