A comprehensive monitoring of fitness, fatigue, and performance is crucial for understanding an athlete's individual responses to training optimize the scheduling recovery strategies. Resting exercise-related heart rate measures have received growing interest in recent decades are considered potentially useful within multivariate response monitoring, as they provide non-invasive time-efficient insights into status autonomic nervous system (ANS) aerobic fitness. In team sports, practical...
The aim of this study was to compare the effects high-intensity interval training (HIIT) and repeated-sprint (RST) on aerobic fitness, tennis-specific endurance, linear ability (RSA), jumping ability. Thirty-one competitive male tennis players took part in a intervention 6 weeks. were matched into 3 groups, HIIT (n = 11), RST 12), or control group (CON, n 9). results showed significant time × interactions for VO(2)peak, with increase VO(2)peak level 6.0% (p 0.008) 4.9% 0.010), whereas no...
Aim Our study aimed to investigate changes of different markers for routine assessment fatigue and recovery in response high-intensity interval training (HIIT). Methods 22 well-trained male female team sport athletes (age, 23.0 ± 2.7 years; V̇O2max, 57.6 8.6 mL·min·kg−1) participated a six-day running-based HIIT-microcycle with total eleven HIIT sessions. Repeated sprint ability (RSA; criterion measure recovery), countermovement jump (CMJ) height, efficiency multiple rebound test (MRJ), 20-m...
Abstract Raeder, C, Wiewelhove, T, Simola, RÁDP, Kellmann, M, Meyer, Pfeiffer, and Ferrauti, A. Assessment of fatigue recovery in male female athletes after 6 days intensified strength training. J Strength Cond Res 30(12): 3412–3427, 2016—This study aimed to analyze changes neuromuscular, physiological, perceptual markers for routine assessment high-resistance Fourteen 9 participated a 6-day training microcycle (STM) designed purposefully overreach. Maximal dynamic (estimated 1 repetition...
Purpose To investigate the effects of different recovery strategies on fatigue markers following a prolonged running exercise. Methods 46 recreational male runners completed half-marathon, followed by active (ACT), cold water immersion (CWI), massage (MAS) or passive (PAS). Countermovement jump height, muscle soreness and perceived stress were measured 24h before half-marathon (pre), immediately after intervention (postrec) race (post24). In addition, contractile properties blood determined...
Objective: In two independent study arms, we determine the effects of strength training (ST) and high-intensity interval (HIIT) overload on cardiac autonomic modulation by measuring heart rate (HR) vagal variability (HRV). Methods: study, 37 well-trained athletes (ST: 7 female, 12 male; HIIT: 9 male) were subjected to orthostatic tests (HR HRV recordings) each day during a 4-day baseline period, 6-day microcycle, recovery period. Discipline-specific performance was assessed before one four...
This study examined the effect of microcycles in eccentric strength and high-intensity interval training (HIT) on sleep parameters subjective ratings. Forty-two well-trained athletes (mean age 23.2 ± 2.4 years) were either assigned to (n = 21; mean 23.6 2.1 or HIT 22.8 2.6 protocol. Sleep monitoring was conducted with multi-sensor actigraphy (SenseWear Armband™, Bodymedia, Pittsburg, PA, USA) log for 14 days. After a five-day baseline phase, participants completed accented six days, two...
This aimed to analyze neuromuscular, physiological and perceptual responses a single bout of 5 different dynamic squat exercise protocols. In randomized counterbalanced order, 15 male resistance-trained athletes (mean ± SD; age: 23.1 1.9 years, body mass: 77.4 8.0 kg) completed traditional multiple sets (MS: 4 × 6, 85% 1 repetition maximum [RM]), drop (DS: 1RM + 3 sets), eccentric overload (EO: 70% concentric, 100% eccentric), flywheel YoYo (FW: all-out), plyometric jump protocol (PJ: 15,...
Objective: Tensiomyography (TMG) is an indirect measure of a muscle's contractile properties and has the potential as technique for detecting exercise-induced skeletal muscle fatigue. Therefore, aim this study was to assess sensitivity tensiomyographic markers identify reduced muscular performance in elite youth athletes. Methods: Fourteen male junior tennis players (age: 14.9 ± 1.2 years) with international (International Tennis Federation) ranking position participated pre-post single...
The nine-year multicenter research project, titled REGman—Optimization of Training and Competition: Management Regeneration in Elite Sports—aimed to advance the understanding recovery management sports generate practical recommendations. In this article, we outline overarching program that links specific strands outputs during two federal funding cycles (2012–2021) summarize main project findings. two-stage conceptual framework involved investigating monitoring measures for short-term...
To investigate the effect of repeated use active recovery during a 4-d shock microcycle with 7 high-intensity interval-training (HIT) sessions on markers fatigue.Eight elite male junior tennis players (age 15.1 ± 1.4 y) an international ranking between 59 and 907 (International Tennis Federation) participated in this study. After each training session, they completed 15 min either moderate jogging (active [ACT]) or passive (PAS) crossover design, which was interrupted by 4-mo washout period....
Purpose According to the official rules of International Tennis Federation, players have serve alternately from two different positions: deuce (right, D) and ad court (left, AD) side. This study aimed compare body ball kinematics flat serves both service sides. Methods In a controlled, semi-court laboratory setting, 14 elite male junior served eight first target field directed receiver’s positions in matched counterbalanced order. An 8-camera-Vicon-System was used capture 3D-landmark...
Objective: High-intensity interval training (HIIT) can be extremely demanding and consequently produce high blood lactate levels. Previous studies have shown that is a potent metabolic stimulus, which important for adaptation. Active recovery (ACT) after intensive exercise, however, enhances removal in comparison with passive (PAS) and, consequently, may attenuate endurance performance improvements. Therefore, the aim of this study was to examine influence regular ACT on adaptations during...
