With limited costs and travel constraints for athletes, the “living low-training high” (LLTH) approach is becoming an important intervention modern sport. The popularity of LLTH model altitude training also associated with fact that it only causes a slight disturbance to athletes’ usual daily routine, allowing them remain in their home environment maintain regular lifestyle. In this perspective article, we discuss evolving boundaries paradigm its practical applications athletes. Passive...

Abstract To investigate the acute effects of hypoxia applied during discrete work and recovery phases a perceptually regulated, high‐intensity interval exercise (HIIE) on external internal loads in inactive overweight individuals. On separate days, 18 (28.7 ± 3.3 kg m −2 ; 31 8 years) men women completed cycling HIIE protocol (6 × 1 min intervals with 4 active recovery, maintaining perceived rating exertion 16 10 respectively, 6–20 Borg scale) randomized conditions: normoxia (NN), normobaric...

Winning times at benchmark international rowing competitions (Olympic Games and World Championships) are known to vary greatly between venues, based on environmental conditions the strength of field. Further variability in boat speed for any given effort is found training environment, with less controlled (i.e., water flow, non-buoyed courses), fewer world class competitors, implementation non-race specific distances intensities. This combination external factors makes it difficult coaches...

Background : Exercise with blood-flow restriction (BFR) is being increasingly used by practitioners working athletic and clinical populations alike. Most early research combined BFR low-load resistance training consistently reported increased muscle size strength without requiring the heavier loads that are traditionally for unrestricted training. However, this field has evolved several different active passive methods emerging in recent research. Purpose This commentary aims to synthesize...

A cyclist's rate of force/torque development (RFD/RTD) and peak can be measured during single-joint or whole-body isometric tests, cycling. However, there is limited understanding the relationship between these measures, mechanisms that contribute to each measure. Therefore, we examined the: (i) quadriceps central peripheral neuromuscular function with RFD/RTD in knee extension, mid-thigh pull (IMTP), sprint cycling; (ii) among protocols.Eighteen trained cyclists completed two...

Abstract The aim of this study was to determine test‐retest reliability and concurrent validity vertical force‐velocity‐power (FVP) profiles using Smith machine free‐weight countermovement jumps (CMJs). A repeated‐measure cross‐over design with randomized load order counterbalanced trials employed. Sixteen resistance‐trained males (age: 26.4 ± 3.9 years, height: 179.6 8.1 cm, body mass: 84.5 10.8 kg) performed maximal loaded CMJs 4–50 kg on six occasions, three utilizing a free‐weights.

This investigation examined the oxidative stress (F2-Isoprostane; F2-IsoP) and inflammatory (interleukin-6; IL-6) responses to repeat-sprint training in hypoxia (RSH). Ten trained male team sport athletes performed 3(sets)*9(repetitions)*5 s cycling sprints simulated altitude (3000 m) sea-level conditions. Mean peak sprint power output (MPO PPO) were recorded, blood samples collected pre-exercise, again at 8 60 min post-exercise. Both MPO PPO significantly reduced (compared sea-level) second...

The aim of this study was to investigate acute performance and physiological responses the manipulation exercise-to-rest ratio (E:R) during repeated-sprint hypoxic training (RSH) in hot conditions.
