This study compared the weekly training load (TL) variation across different measures. Fifty-two runners reported their heart rate and distance ran for each training session during four weeks of training. Heart rate measures were used to calculate the weekly TRaining IMPulse (W-TRIMP), whereas the distance ran was used to calculate the weekly…

This article explores an innovative educational approach using a metabolic board designed to enhance understanding of muscle metabolism across three endurance training zones: Z1 (light intensity), Z2 (moderate intensity), and Z3 (intense/severe intensity). The aerobic threshold marks the transition from light to moderate domains and the anaerobic…

Heart rate samples (n = 4500-8000) from wearables were compared to electrocardiography during a steady-state ruck (Ruck-S), maximal effort ruck (Ruck-M), submaximal cycle (Cycle), and Tabata Circuit. One device was worn at each location (wrist: Polar Grit-X, Garmin Fenix 6; chest-straps: Polar H10, Garmin HRM-Pro; armband: Polar Verity).…

Purpose: Heart rate variability (HRV) can be used to monitor changes in autonomic nervous system (ANS) function. Monitoring HRV via the natural log of the root-mean-square difference of successive normal RR intervals (lnRMSSD), a decrease was related to lower parasympathetic activity and a fatigued state, and an increase was related to higher…

In the Republic of Kazakhstan, specialists in the field of Physical culture and Sports are faced with the problem of increasing interest in practicing folk national sports, based on the creation of both theoretical paradigms and a more evidence-based comprehensive practical database of research in scientific and methodological orientation. The…

Many factors determine success in football. But the most important of these are the physical and physiological variables that determine the performance of football players. Meeting these physical and physiological needs is also based on training methods prepared following branch-specific neural, muscular, and metabolic parameters. In football, for…

The objective of this research has been the analysis of the effectiveness of sports performance through a program, based on the assimilation of contents from a previous diagnosis. The almost-experimental design was applied like a pre- during program. Eighty-two students from Basic Education Career of UPSE have participated in this study, developed…

Purpose: The purpose of this study was to examine the physical match profiles of professional soccer players using 3 and 5 min fixed and rolling averages as well as fixed 1 min averages, with considerations to training prescription. Methods: Twenty-nine professional U23 soccer outfield players competed across 17 competitive matches during the…

Accurate determinations of individuals' one-repetition maximum (1RM) are critical when evaluating the effectiveness of an exercise intervention involving progressive resistance training (RT). Traditional ("bottom-up"; BT) testing methods involve progressions from low to maximal loads and are commonly used in clinical and laboratory…

The aim of this study was to describe how major leg muscle activities are altered after learning a novel one-legged pedaling task. Fifteen recreational cyclists practiced one-legged pedaling trials during which they were instructed to match their applied pedal force to a target direction perpendicular to the crank arm. Activity in 10 major leg…

The purpose of this article is to overview the cardiovascular fitness benefits associated with HIIT and speed training, as well as discuss specific ways coaches and fitness professionals can introduce and promote speed workouts as a viable, and creative, exercise alternative.

Sport coaches can agree that various levels of practice and play contribute significantly to the overall development of a young athlete. Coaches of young athletes need to also address issues related to strength and conditioning as part of the developmental cycle. Unfortunately, many sport coaches are not well trained in the science related to…

To assess the acute effect of strength exercises combined with EMS on blood flow and muscle stiffness using SMI and SWE. This prospective study included 20 participants. Subjects were divided into groups base on calisthenics strength training with EMS and without EMS. Rectus femoris (RF) blood flow was measured at rest and post-exercise with the…

The purpose of this study was to examine the effects of a 6-week skill-based volleyball training program on the running economy (RE) of male competitive volleyball players. Ten male amateur volleyball players (age 21.1 ± 1.5 years) participated in a 6-week skill-based volleyball training program three times a week in the pre-season preparatory…

Purpose: This study compared the acute effects of two different resistance training methods on heart rate variability, blood pressure, and rating of perceived exertion in patients with liver cirrhosis. Methods: Ten patients with Child-Pugh A (seven women and three men) participated in two experimental sessions, in random order: The traditional set…
