Associations between grip strength and incident type 2 diabetes: findings from the UK Biobank prospective cohort study
(BMJ PUBLISHING GROUP, 2021-08-29)Introduction Grip strength has been associated with chronic diseases and mortality. However, current evidence of the association between grip strength and incident type 2 diabetes mellitus (T2DM) is controversial. The aim ... -
Hypoxic Respiratory Chemoreflex Control in Young Trained Swimmers
(FRONTIERS MEDIA SA, 2021-03-29)During an apnea, changes in PaO2 activate peripheral chemoreceptors to increase respiratory drive. Athletes with continuous apnea, such as breath-hold divers, have shown a decrease in hypoxic ventilatory response (HVR), ... -
Effects of different resistance training frequencies on body composition and muscular performance adaptations in men
(PEERJ INC, 2021-05-24)Background: The aim of this study was to compare the effects of 8 weeks resistance training (RT) with two sessions versus four sessions per week under volume load-equated conditions on body composition, maximal strength, ... -
The Hamstrings: Anatomic and Physiologic Variations and Their Potential Relationships With Injury Risk
(FRONTIERS MEDIA SA, 2021-07-07)The incidence and recurrence of hamstrings injuries are very high in sports, posing elevated performance and financial-related costs. Attempts to identify the risk factors involved in predicting vulnerability to hamstrings ... -
Strength Training versus Stretching for Improving Range of Motion: A Systematic Review and Meta-Analysis
(MDPI, 2021-05-11)Background: Stretching is known to improve range of motion (ROM), and evidence has suggested that strength training (ST) is effective too. However, it is unclear whether its efficacy is comparable to stretching. The goal ... -
Unilateral versus Bilateral Landing after Spike Jumps in Male and Female Volleyball: A Systematic Review
(MDPI, 2021-08-06)Background: The spike is a key action in volleyball, and the landing technique and its asymmetries are commonly associated with an increased risk of injury. Objectives: The aim of this systematic review was to assess how ... -
The Effectiveness of Post-exercise Stretching in Short-Term and Delayed Recovery of Strength, Range of Motion and Delayed Onset Muscle Soreness: A Systematic Review and Meta-Analysis of Randomized Controlled Trials
(FRONTIERS MEDIA SA, 2021-05-05)Background: Post-exercise (i.e., cool-down) stretching is commonly prescribed for improving recovery of strength and range of motion (ROM) and diminishing delayed onset muscular soreness (DOMS) after physical exertion. ... -
Effect of warm-up on hand grip strength in sedentary overweight women
(Universidad Nacional de Colombia, 2020-11)Introduction: In recent years, handgrip strength assessment has gained special relevance in health. However, a standardized application protocol that includes warm-up procedures is required to measure it. Objective: To ... -
The joint association of sarcopenia and frailty with incidence and mortality health outcomes: A prospective study
(Churchill Livingstone, 2021-04)Background: Sarcopenia and frailty are strongly associated with disease incidence and mortality. However, there is limited evidence regarding their joint association with health outcomes. This study aimed to investigate ... -
Methodological design for the assessment of physical activity and sedentary time in eight Latin American countries - The ELANS study
(Elsevier BV, 2020-03)Worldwide studies of physical activity and sedentary time have historically under-represented low- and middle-income countries due to the lack of surveillance data. The purpose of this paper is to describe the methods and ... -
Neuronal HIF-1 alpha in the nucleus tractus solitarius contributes to ventilatory acclimatization to hypoxia
(Wiley-Blackwell Publishing Ltd, 2020-05)We hypothesized that hypoxia inducible factor 1 alpha (HIF-1 alpha) in CNS respiratory centres is necessary for ventilatory acclimatization to hypoxia (VAH); VAH is a time-dependent increase in baseline ventilation and the ... -
Is waist-to-height ratio a better predictor of hypertension and type 2 diabetes than body mass index and waist circumference in the Chilean population?
(Elsevier Inc., 2020-12)Objective: The aim of this study was to identify which anthropometric measurement (body mass index [BMI], waist circumference [WC], or waist-to-height ratio [WHtR]) is a better predictor of type 2 diabetes and hypertension ... -
Optimal cut-off points for waist circumference in the definition of metabolic syndrome in Chile
(Cambridge University Press, 2020-11)Objective: To identify sex-specific cut-off points for waist circumference (WC) in the definition of metabolic syndrome (MetS) for the Chilean adult population. Design: MetS was defined as the presence of at least two out ... -
Effects of plyometric jump training in female soccer player's vertical jump height: A systematic review with meta-analysis
(Routledge, 2020-07)To assess the effects of plyometric jump training (PJT) in female soccer player's vertical jump height, a review was conducted using the data sources PubMed, MEDLINE, Web Of Science and SCOPUS. Only peer-review articles ... -
Effects of Plyometric Jump Training on Jump and Sprint Performance in Young Male Soccer Players: A Systematic Review and Meta-analysis
(Springer International Publishing AG, 2020-12)Background Even from a young age, modern soccer requires high levels of physical fitness development, particularly jumping and sprinting. Plyometric jump training (PJT), combined with young athletes' regular soccer sessions, ... -
