Timed Up-and-Go as a predictor of fracture risk: A systematic review and meta-analysis in a population of over 1.6 million people
Objectives: This systematic review aimed to synthesize evidence from prospective cohort studies assessing the Timed Up-and-Go (TUG) test as association of fracture risk in older people, and to quantify the association through meta-analysis using hazard ratios (HR). Methods: Two authors independently conducted systematic searches in PubMed/MEDLINE, Scopus, Web of Science, CINAHL Complete, and the Psychology and Behavioral Sciences Collection. MEDL…
Effects of boxing interventions on physical fitness and health-related quality of life in older people with Parkinson’s disease: A systematic review with meta-analysis
Effects of active exergames on physical performance in older people: An overview of systematic reviews and meta-analysis
This overview assessed the available body of published peer-reviewed systematic reviews and meta-analyses related to the effects of active exergames compared with active/passive control on physical performance outcomes in older people. The methodological quality and certainty of evidence were assessed using PRISMA, AMSTAR 2, and GRADE. The protocol was registered in PROSPERO (code: CRD42023391694). The main outcomes indicate that 4,477 records, f…
Impact of adapted taekwondo vs. multicomponent training on health status in independent older women: A randomized controlled trial
This study, called the TKD and Aging Project, aimed to analyze and compare the effects of an adapted taekwondo program concerning multicomponent training on blood pressure, morphological variables, food consumption frequency, health-related quality of life (HRQoL), physical fitness, handgrip strength, and postural balance in independent older women. A randomized controlled trial study was conducted with parallel groups for 8 weeks (24 sessions of…
Factors Associated with Anxiety, Depression, and Stress Levels in High School Students
This study aims to investigate the relationship between anxiety, depression, and stress levels with physical activity level and academic performance in high school students; secondly, this study aims to relate and compare anxiety, depression, and stress levels with physical activity level and academic performance. This is a quantitative, descriptive, and comparative cross-sectional study, which evaluated 443 high school students (48% female; 15.1…
Validity and Reliability of Short-Term Heart Rate Variability Parameters in Older People in Response to Physical Exercise
Our results provide moderate to strong evidence for using HRV to measure cardiac autonomic response to moderate exercise, suggesting that it is sufficiently reliable to show similar results to those shown in this test-retest protocol
Relation between VT1, VT2, and VO2max with the Special Wrestling Fitness Test in Youth Wrestlers: A Short Report
This study investigated the relationship between peak oxygen uptake and ventilatory threshold 1 (VT1) and 2 (VT2) with the Special Wrestling Fitness Test variables. Thirteen wrestlers (male: six; female: seven) of Olympic freestyle wrestling were assessed. The Pearson's correlation coefficient ( p p = 0.002; 95%CI = 0.37-0.93), total throws (r = 0.73; p = 0.004; 95%CI = 0.30-0.91), heart rate recovery (r = 0.58; p = 0.036; 95%CI = 0.05-0.86), and…
Association between Physical Activity Habits with Cardiometabolic Variables, Body Composition, and Physical Performance in Chilean Older Women
This study aimed to associate physical activity habits with cardiometabolic variables (blood pressure, fasting glucose, HDL cholesterol, and triglycerides), body composition (body fat percentage and fat-free mass), and physical performance (handgrip strength (HGS), timed up-and-go (TUG), and walking speed) in Chilean older women. An analytical cross-sectional study analyzed 179 older women with a mean age of 75.4 years distributed into physically…
Effectiveness of elastic band training and group-based dance on physical-functional performance in older women with sarcopenia: A pilot study
Elastic band training produces significantly greater responses on physical-functional performance regarding group-based dance in older women with sarcopenia. On the other hand, the EBG revealed a significant improvement in fat-free mass and upper and lower limb muscle strength, as well as a significant decrease time in TUG, and walking speed. Elastic band exercise is a safe, easy, affordable, and effective physical activity strategy, according to…
Relative and Chronological Age in Successful Athletes at the World Taekwondo Championships (1997–2019): A Focus on the Behaviour of Multiple Medallists
The aims of this study were to investigate the relative and chronological age among taekwondo world medal winners (by gender, Olympic 4-year period, Olympic weight category; N = 740), and to study the behaviour of multiple medallists ( N = 156) to monitor changes in weight categories and wins over time. The observed birth quartile distribution for the heavyweight category was significantly skewed ( p = 0.01). Female athletes (22.2 ± 3.5 years) ac…
Factors Associated with Poor Health-Related Quality of Life in Physically Active Older People
This study aimed to associate morphological variables and physical fitness with health-related quality of life (HRQoL) in physically active older people. A cross-sectional study was carried out that evaluated 470 older people (89.57% female) with a mean age of 70.13 ± 6.57 years, residing in two regions of Chile. Morphological variables (body weight, bipedal height, waist circumference, body mass index, and waist to height ratio), physical fitnes…
Warm-Up and Handgrip Strength in Physically Inactive Chilean Older Females According to Baseline Nutritional Status
This study aims to analyze the effect of different types of warm-ups on handgrip strength (HGS) in physically inactive older females. Secondarily, it aims to compare HGS according to their baseline nutritional status. A randomized crossover trial study was conducted with 44 physically inactive older females distributed into normal weight (n = 12, BMI = 23.9 ± 3.2 kg/m 2 ), overweight (n =16, BMI = 27 ± 4.7 kg/m 2 ) and obese (n = 16, BMI = 31.6 ±…
Effect of a Six Week In-Season Training Program on Wrestling-Specific Competitive Performance
The effect of multi-component training on specific performance is under-researched in wrestlers. The aim of this study was to determine the effect of six weeks of multi-component training on The Special Wrestling Fitness Test (SWFT) performances of wrestlers who were preparing for an international championship, and to, additionally, determine their inter-individual adaptive variability. The wrestlers (n = 13; 7 females; all international level) u…
Developing flexibility for combat sports athletes
The range of motion of a joint is extremely important in combat sports, especially when there is a need to execute a certain motor gesture with maximum range of movement, as in throwing techniques such as uchi-mata in judo, certain types of guards in Brazilian jiu-jitsu or the high kicks common in a variety of striking combat sports. Therefore, in this chapter, we will discuss the elements related to flexibility response during training sessions …
Effects of 4 Weeks of a Technique-Specific Protocol with High-Intensity Intervals on General and Specific Physical Fitness in Taekwondo Athletes: An Inter-Individual Analysis
The aim of this research was to compare the effects of a technique-specific high-intensity interval training (HIIT) protocol vs. traditional taekwondo training on physical fitness and body composition in taekwondo athletes, as well as to analyse the inter-individual response. Utilising a parallel controlled design, sixteen male and female athletes (five females and 11 males) were randomly divided into an experimental group (EG) that participated …
Recomendaciones de entrenamiento intervalado para atletas de deportes de combate olímpicos durante la pandemia del Covid-19
La pandemia del COVID-19 ha obligado a los gobiernos decretar cuarentena y aislamiento social en la población con la intención de aplanar la curva de contagio, hechos que han afectado de igual modo la preparación de los atletas. En dicho contexto, hemos desarrollado algunas recomendaciones de entrenamiento intervalado de alta intensidad (HIIT) que podrían ejecutar atletas de deportes de combate olímpicos en sus hogares. Los protocolos HIIT debies…
High-intensity interval training improves specific performance in taekwondo athletes
Specific training methods is an important aspect in the preparation of taekwondo athletes.
