Lifestyle Behaviours in Pre-Schoolers from Southern Spain-A Structural Equation Model According to Sex and Body Mass Index.

Objectives: The present study aimed to examine the relationship between screen time (ST), sleep time (SLT), physical fitness (PF), Mediterranean diet (MD) adherence, eating behaviours, and body mass index (BMI) in a sample of pre-schoolers from Granada (Spain). In order to address this aim, an explanatory model was developed to examine existing relationships between ST, SLT, PF, MD, pro-intake (PRO-I) and anti-intake (ANT-I) behaviours, and BMI. Further, the proposed structural model was examined via multi-group analysis as a function of sex and BMI.

Anti-Doping Knowledge of Students Undertaking Bachelor's Degrees in Sports Sciences in Spain.

In Spain, students pursuing a career in athletic training, physical education, or scientific evaluation of sports enroll in a bachelor’s degree in sports sciences. This degree provides knowledge and skills in a broad array of sports settings and promotes research-based interdisciplinary knowledge. However, the student’s syllabus rarely includes specific academic training on anti-doping regulations or doping prevention.

Validity and Reliability of Two Near-infrared Spectroscopy Devices to Measure Resting Hemoglobin in Elite Cyclists.

A new method to monitor internal training load from muscle oxygen saturation using near-infrared spectroscopy could be of practical application for research and training purposes. This technology has been validated in different scientific fields, including sports science, and Humon Hex and Moxy are two leading brands. However, its relationship with hemoglobin has not been studied.

Determination of Second Lactate Threshold Using Near-infrared Spectroscopy in Elite Cyclists.

The use of near-infrared spectroscopy could be an interesting alternative to other invasive or expensive methods to estimate the second lactate threshold. Our objective was to compare the intensities of the muscle oxygen saturation breakpoint obtained with the Humon Hex and the second lactate threshold in elite cyclists. Ninety cyclists performed a maximal graded exercise test.
