New and promising variables are being developed to analyze performance fatigue in trail running, such as mechanical power, metabolic cost of transport efficiency. The aim this study was the behavior these during a real vertical kilometer field test. Fifteen trained runners, eleven men (from 22 38 years old) four women 19 35 performed with length 4.64 km 835 m positive slope. During entire race, runners were equipped portable gas analyzers (Cosmed K5) assess their cardiorespiratory responses...

Ethnography is one of the most relevant methods in qualitative research, and both psychology sociology use their research. This essential when purpose to keep historical memory different population relation facts or experiences from past. In a firstly phase, ethnography could expedite study's variables description. Based on implication variable's conceptualization obtained by this first phase (ethnographic), subsequent phases researchers might deepen concepts still using descriptive...

Goalball is a sport for visually impaired athletes, where the roles of attack and defense change continuously during game. Performance evaluation should consider variables that determine throwing stop clearance ball. The aim this study to evaluate precision velocity ball in goalball, besides core stability balance as an optimal throwing. Moreover, novel acoustic reaction time applied analyze performance. Eight goalball players (33 ± 9 years old; 77.8 22.7 kg; 174 13 cm; 10 5 experience) were...

Background: Vertical kilometer is an emerging sport where athletes continuously run uphill. The aims of this study were to assess changes in vertical impacts caused by uphill running (UR) and the relation between anthropometric lower limb muscular characteristics with speed. Methods: Ten male experienced runners (35 ± 7 years old) participated study. In racetrack (4.2 km long, 565 m high), seven sections stablished. Mean speed impact value similar slope (≈21%) calculated. gastrocnemius...

In youth sport contexts, aggressiveness and violence constitute a deplorable social phenomenon. There are sportsmanlike conducts as forms of alternatives to these types behaviors. Specifically, the present paper aims introduce characteristics evaluation tools used assess sportiveness, constructs in sporting environments general and, more precisely, sport. The methods evaluate previous described based on bibliometric analysis information base obtained from psychology, physical activity sports...

J Strength Cond Res 38(11): 1849-1853, 2024-The objective of current research was to analyze load-velocity (BSS) exercise compare these relationships between dominant nondominant legs. Twenty-one strength-trained men (age: 27.3 ± 7.3 years) performed a progressive loading test BSS using Smith machine for each leg. The protocol began with...

In athletic training and research, the evaluation of sprint speed is widely used, its accurate measurement especially demanding. High-cost photocells are gold-standard system for time assessment, although low-cost smartphone applications can be a suitable option. This study assesses validity reliability an application to measure compared photocells. Five physically active subjects completed six sprints 10 m 20 at maximal 5 go return evaluate Photo Finish

The aim of this study was to quantify trunk impact dynamics in goalball players using inertial sensors and evaluate the players’ workloads, focusing on changes between first second halves a match enhance understanding demands experienced throughout game. Utilizing technology, impacts during gameplay were analyzed provide holistic insight into how these influence athletes’ dynamic stress loads, which refers physical placed body movements. Six recruited wear an accelerometer whole game...

Research into key performance factors in trail running, particularly vertical kilometer (VK) races, is crucial for effective training and periodization. However, recent studies on metabolic cardiorespiratory responses during VK especially using field tests, are limited.

El feedback tiene un enorme potencial para mejorar los resultados de aprendizaje alumnos. Sin embargo, las prácticas concretas que se realizan en aulas universitarias no consiguen aprovechar esos beneficios por diferentes razones. Nosotros sostenemos una planificación sistemática puede estas y entendemos “diseñar” “planificar” como toma decisiones intencional e informada la investigación. Tomando consideración últimos avances estudios sobre feedback, proponemos enfoque -feedback by design-...
