Abstract

Objective: Present study was intended to examine the effects of dietary modification on nutritional biomarkers in young Indian male athletes. Methods: Eighty-eight footballers and hockey players were randomly segregated into ad-libitum group (ALG) and nutrition counselling group (NCG). Eight weeks of dietary modification trial was implemented on NCG, resulting in 9.5, 2.6, and 2.1 g/kgbw/day of carbohydrate, protein, and fat respectively. Rate of changes in daily nutrient intake and nutrition biomarkers were captured. Results: NCG revealed significant increases in total serum protein (5.6%, p<0.001), haemoglobin (3.9%, p<0.001) and vitamin E (2.9%, p<0.001). They also exhibited rises in serum vitamin C (6%, p=0.004), folate (4.5%, p=0.004), ferritin (4.8%, p=0.003), calcium (4.2%, p=0.009), serum vitamins B12 (3.9%, p=0.012) and D (12.3%, p<0.001). Haemoglobin levels were positively correlated with daily protein (p<0.01), iron (p<0.05), vitamins B12 and vitamin C (p<0.05 both) intakes. Serum calcium positively correlated with daily calcium (p<0.01), phosphorus and protein (p<0.05 both) intakes. Serum zinc was positively correlated with daily protein, calcium, vitamin B9 and vitamin D intake, while serum ferritin and vitamin B12 were positively correlated with protein and iron intake. Post-intervention, NCG reported optimal blood levels of calcium, zinc, protein, Hb, ferritin, vitamins B12, C and E, whereas the folate and vitamin D values were suboptimal. On the other hand, the ALG revealed marginal levels of zinc and total protein as well as noticeably low levels of calcium, folate, and vitamin D. Conclusion: Enhanced blood levels of nutritional biomarkers noted after eight-weeks of controlled dietary modification was supported by positive correlations observed with the daily nutrient intakes.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
