“…The sub-optimal O3i observed for in our study (4.3%) was similar to previous observations [39,44,56,57], and did not differ based on sex or sport. Football-specific findings in this study were virtually identical to previous findings in Division I football athletes with both groups averaging an O3i of 4.4% [44].…”

Omega-3 fatty acids (ω-3 FA) are associated with cardiovascular health, brain function, reduction of inflammation, and several other physiological roles of importance to competitive athletes. The ω-3 FA status of National Collegiate Athletic Association (NCAA) Division I athletes has not been well-described. The purpose of this study was to evaluate the ω-3 FA status of NCAA Division I athletes using dietary and biological assessment methodology. Athletes from nine NCAA Division I institutions from throughout the U.S. (n = 1,528, 51% male, 34 sports represented, 19.9 ± 1.4 years of age) completed a food frequency questionnaire (FFQ) to assess ω-3 FA from diet and supplements. Omega-3 Index (O3i) was evaluated in a subset of these participants (n = 298, 55% male, 21 sports represented, 20.0 ± 1.3 years of age) using dried blood spot sampling. Only 6% (n = 93) of athletes achieved the Academy of Nutrition & Dietetics' recommendation to consume 500 mg DHA+EPA per day. Use of ω-3 FA supplements was reported by 15% (n = 229) of participants. O3i was 4.33 ± 0.81%, with no participants meeting the O3i benchmark of 8% associated with the lowest risk of cardiovascular disease. Every additional weekly serving of fish or seafood was associated with an absolute O3i increase of 0.27%. Overall, sub-optimal ω-3 FA status was observed among a large, geographically diverse group of male and female NCAA Division I athletes. These findings may inform interventions aimed at improving ω-3 FA status of collegiate athletes. Further research on athlete-specific ω-3 FA requirements is needed.

“…The sub-optimal O3i observed for in our study (4.3%) was similar to previous observations,(39,44,53,54) and did not differ based on sex or sport. While further research is needed to investigate potential differences in needs between athletes of different sex and sport, these we observed collegiate athletes collectively have low ω-3 FA status.…”

AbstractOmega-3 fatty acids (ω-3 FA) play a number of important functions in health and human performance. While previous research has suggested that low ω-3 FA status is prevalent in the general population, little information about athletes’ ω-3 FA status is available. The purpose of this study was to assess the omega-3 fatty acid (ω-3 FA) status of collegiate athletes. Dietary ω-3 FA intake was evaluated in athletes from nine NCAA Division I institutions (n=1,528, 51% male, 19.9 ± 1.4 years of age, 29 sports represented) via food frequency questionnaire. Omega-3 Index (O3i) was assessed using a dried blood spot sample in a subset of these athletes (n=228). Only 6% (n = 93) of athletes achieved the Academy of Nutrition & Dietetics’ recommendation to consume 500 mg of the ω-3 FA’s docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) per day. Use of ω-3 FA supplements was reported by 15% (n = 229) of participants. O3i was 4.33 ± 0.81%, with zero participants meeting the O3i benchmark of 8% associated with the lowest risk of cardiovascular disease. Every additional weekly serving of fish or seafood was associated with an absolute O3i increase of 0.27%. Overall, sub-optimal ω-3 FA status was observed among a large, geographically diverse group of male and female collegiate athletes. These findings may inform interventions aimed at improving ω-3 FA status of collegiate athletes. Further research on athlete-specific ω-3 FA requirements is needed.

“…The omega-3 index (OM3I), a validated, reliable and reproducible biomarker for the assessment of omega-3 status, represents the percentage of the long chain marine fatty acids EPA and DHA as a proportion (%) of the total RBC fatty acids [59]. Data are now available in athletic populations: a mean (standard deviation) of 5.1 (1.0)% in Summer Olympians [65], 4.9 (1.2)% in Winter Olympians [66] and 4.4 (0.8)% in National Collegiate Athletic Association Division 1 collegiate footballers [67]; however, wide inter-athlete variability was consistently observed. These findings in athletes contrast with an average OM3I of 3.7 (1.0)% in a large cohort of vegans, 3.5 (0.7)% in US military servicemembers, and a median OM3I of 7.1% in a Spanish cohort consuming a Mediterranean diet [68–70].…”

Blood Biomarker Profiling and Monitoring for High-Performance Physiology and Nutrition: Current Perspectives, Limitations and Recommendations

2019

Blood test data were traditionally confined to the clinic for diagnostic purposes, but are now becoming more routinely used in many professional and elite high-performance settings as a physiological profiling and monitoring tool. A wealth of information based on robust research evidence can be gleaned from blood tests, including: the identification of iron, vitamin or energy deficiency; the identification of oxidative stress and inflammation; and the status of red blood cell populations. Serial blood test data can be used to monitor athletes and make inferences about the efficacy of training interventions, nutritional strategies or indeed the capacity to tolerate training load. Via a profiling and monitoring approach, blood biomarker measurement combined with contextual data has the potential to help athletes avoid injury and illness via adjustments to diet, training load and recovery strategies. Since wide inter-individual variability exists in many biomarkers, clinical populationbased reference data can be of limited value in athletes, and statistical methods for longitudinal data are required to identify meaningful changes within an athlete. Data quality is often compromised by poor pre-analytic controls in sport settings. The biotechnology industry is rapidly evolving, providing new technologies and methods, some of which may be well suited to athlete applications in the future. This review provides current perspectives, limitations and recommendations for sports science and sports medicine practitioners using blood profiling and monitoring for nutrition and performance purposes.
