Research on heart rate (HR), mean arterial pressure (MAP) and blood pressure (BP) during specific training stages is less common in endurance athletes, whereas resting BP and HR are less studied in relationship to HRmax. In the current study, the objective was to conduct a medium-term HR, BP and MAP analysis while tracking individual training outcomes. The study was conducted during the 2017–2018 season, over 43 days and 1033 km of training volume, on 12 competitive male cross-country ski athletes. One VO2max test was performed 10 days before the start of the training program. After the test, training volume and intensity was preset for each subject, according to the general training methodology. Early morning HR, MAP and BP measurements were taken as part of the basic functional analysis. Training volume was correlated to both distance (p = 0.01, r = 0.85, CI95% = 0.80 to 0.88) and training HR%, namely the percentage of HRmax (p = 0.01, r = −0.47, CI95% = −0.58 to −0.34). Both the supine (sHR) and orthostatic HR (oHR) values were significantly correlated with the training intensity. We obtained a significant correlation between sHR and oHR values and the training objective (p = 0.01). An increased oHR was correlated to high intensity training activity (HIT) during the second training session (p = 0.01). Heart rate and blood pressure measurements represent predictive functional adaptation parameters over different training phases. We highlight a link between sHR, oHR, MAP data, and the athletes’ ability to perform in lower effort zones during physical exertion. However, we failed to validate MAP as a cardiovascular stress indicator following high intensity training.
Imbalanced food intake due to high fat consumption tends to have important consequences over general health conditions, regardless of age. The aim of this paper was to analyze fat intake considering the child`s general nutritional needs, micronutrient requirements and the main anthropometric development data. A transversal study has been conducted on a sample of 287 healthy Romanian children aged 36 to 84 months. The sample was divided into: underweight, normal weight and overweight study groups. Among the study subjects, the total fat intake was lower than the daily references depending on gender and age (p=0.0001). Differences were identified between both saturated (p=0.0001) and unsaturated (p=0.0001) fat intake. Saturated fat intake was significantly correlated with the body weight (p=0.0001), the height (p=0.001) and the BMI (p=0.001). Both dietary cholesterol (p=0.018; r=0.189) and saturated fat (p=0.01; r=0.265) were related to individual height. Lack of relationship was seen regarding zinc, selenium, sodium and fat intake (p>0.05). Yet, monounsaturated fat intake was correlated with iron, magnesium and phosphor. Polyunsaturated fat intake was correlated with both phosphorus and potassium in the underweight group. Conclusions: Daily lack of dietary fats have been associated with a significant decrease in growth speed, weight gain and a higher risk of general developmental delay.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
