Effects of Resistance Training in Hypobaric vs. Normobaric Hypoxia on Circulating Ions and Hormones
Hypobaric hypoxia (HH) seems to lead to different responses compared to normobaric hypoxia (NH) during physical conditioning. The aim of the study was to analyze the hormonal and circulating ion responses after performing high-intensity resistance training with different inter-set rest under HH and NH condition. Sixteen male volunteers were randomly divided into two training groups. Each group completed two counterbalanced resistance training ses…
Intermittent Hypoxia as a Therapeutic Tool to Improve Health Parameters in Older Adults
Aging is associated with metabolic alterations, and with a loss of strength, muscle and bone mass. Moderate intermittent hypoxia has been proposed as a new tool to enhance health-related function. The aim of this study was to evaluate the effect of moderate intermittent hypoxia exposures on parameters related to cardiovascular and bone health in older adults. A total of 38 healthy older adults (aged 65-75 years) were divided into two groups: cont…
Measurement of resting muscle oxygenation and the relationship with countermovement jumps and body composition in soccer players (Medición de la oxigenación muscular en reposo y la relación con los sa…
The measurement of resting muscle oxygenation capacity is under investigation in team sports. The aim of the current study was to observe the changes after a preseason, in muscle oxygen saturation (SmO2) at rest and the relationship with body composition and jump power in soccer players. 17 soccer players (age 21.8 ± 2.2 years) were enrolled. Body composition, somatotype, countermovement jump (CMJ) and single-leg countermovement jump (SLCMJ) were…
Muscle Oxygen Desaturation and Re-Saturation Capacity Limits in Repeated Sprint Ability Performance in Women Soccer Players
Muscle oxygen consumption could provide information on oxidative metabolism in women soccer players. Therefore, the objective of this study was to analyze muscle oxygenation dynamics during repeated sprint ability (RSA): (8 sprint × 20 s recovery) by near-infrared spectroscopy (NIRS). The sample was made up of 38 professional women soccer players. To measure the external load, the best time, worst time, average time, individual speed, sprint decr…
Outpatient Assessment of Mechanical Load, Heat Strain and Dehydration as Causes of Transitional Acute Kidney Injury in Endurance Trail Runners
Endurance trail running may lead to an increase in blood and urine indicators of transitional AKI. The difference in blood and urine markers was significantly related to the mechanical load during running, suggesting potential kidney overload and cumulative mechanical load
Six-months CrossFit training improves metabolic efficiency in young trained men (Seis meses de CrossFit mejora la eficiencia metabólica en jóvenes entrenados)
The objective was to analyse the effects of 6 months’ CrossFit on physical performance, metabolic efficiency, body composition, and biochemical parameters. Ten trained CrossFit practitioners were assessed before and after CrossFit training. Anthropometric measurements, biochemical parameters and physical performance parameters were assessed with functional and incremental tests. After 6 months of CrossFit, fat oxidation rate and energy percentage…
Impact of Active and Passive Hypoxia as Re-Warm-Up Activities on Rugby Players’ Performance
The aim of this study was to analyse the effect of four types of re-warm-up (R-WU) activity, namely rest in normoxia (RN) at FiO 2 = 20.9%, rest in hypoxia (RH) at FiO 2 = 15%, activity (4 × 5 jumps/15 s) in normoxia (AN) and activity in hypoxia (AH) on physical performance. Ten elite male rugby players completed a 15-min warm-up followed by one of the 15-min randomized R-WU strategies. After R-WU, countermovement jump (CMJ), 20 m sprint and repe…
External Workload Indicators of Muscle and Kidney Mechanical Injury in Endurance Trail Running
Muscle and kidney injury in endurance athletes is worrying for health, and its relationship with physical external workload (eWL) needs to be explored. This study aimed to analyze which eWL indexes have more influence on muscle and kidney injury biomarkers. 20 well-trained trail runners (age = 38.95 ± 9.99 years) ran ~35.27 km (thermal-index = 23.2 ± 1.8 °C, cumulative-ascend = 1815 m) wearing inertial measurement units (IMU) in six different spo…
Abdominal obesity in adolescents
Objectives The purpose of this study was to develop age‐ and sex‐specific waist circumference (WC) cut‐off points, linked to older adolescent and adult criteria for abdominal obesity, to be applied to children in the clinical setting. Methods A total of 16,788 adolescents aged 10 to 16 years were assessed for WC. Smoothed age and sex‐specific WC curves were obtained using Cole's LMS method. Results Percentiles that corresponded to the Internation…
Desaturación arterial de oxígeno en mujeres pre y postmenopáusicas durante la realización de ejercicio aeróbico. (Arterial oxygen desaturation in pre- and post-menopausal women during aerobic exercise…
La pulsioximetría ha sido validada como una técnica muy fiable para valorar de forma no invasiva la saturación arterial. Nos proponemos estudiar qué variaciones sufren los niveles de SaO2 durante la realización de ejercicio aeróbico en distintos grupos de mujeres: pre y postmenopáusicas. Para ello clasificaremos las desaturaciones en leves, moderadas y graves. Contamos con la participación consentida y voluntaria de 31 mujeres sedentarias, dividi…
