Monitoring the load placed on athletes in both training and competition has become a very hot topic sport science. Both scientists coaches routinely monitor loads using multidisciplinary approaches, pursuit of best methodologies to capture interpret data produced an exponential increase empirical applied research. Indeed, field developed with such speed recent years that it given rise industries aimed at developing new novel paradigms allow us precisely quantify internal external help...

The relationship between recovery and fatigue its impact on performance has attracted the interest of sport science for many years. An adequate balance stress (training competition load, other life demands) is essential athletes to achieve continuous high-level performance. Research focused examination physiological psychological strategies compensate external internal training loads. A systematic monitoring subsequent implementation routines aims at maximizing preventing negative...

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...

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...

The purpose of the study was to analyze tensiomyography (TMG) sensitivity changes in muscle force and neuromuscular function rectus femoris (RF) using TMG properties after 5 different lower-limb strength training protocols (multiple sets; DS = drop eccentric overload; FW flywheel; PL plyometrics). After baseline measurements, 14 male trained athletes completed 1 squat protocol per week over a 5-week period randomized controlled order. Maximal voluntary isometric contraction (MVIC),...

Athlete self-report measures (ASRM) have the potential to provide valuable insight into training response; however, there is a disconnect between research and practice that needs be addressed; namely, measure or methods used in are not always reflective of practice, data primarily obtained from lacks empirical quality. This commentary reviews existing psychometric properties required considered acceptable for practice. information will allow discerning readers make judgment on quality ASRM...

Monitoring recovery in the context of athletic performance has gained significant importance during recent years. As a systematic process data collection and evaluation, monitoring can be implemented for various purposes. It may help prevent negative outcomes training or competition, such as underrecovery, overtraining, injuries. Furthermore, it aims to establish routines strategies necessary guarantee athletes' readiness by restoring their depleted resources. Comprehensive ideally...

To analyze performance and fatigue effects of small-sided games (SSG) vs high-intensity interval training (HIIT) performed during a 4-wk in-season period in high-level youth football.Nineteen players from 4 teams (16.5 [SD 0.8] y, 1.79 [0.06] m, 70.7 [5.6] kg) the 2 highest German divisions completed study. Teams were randomly assigned to 1 sequences (2 endurance sessions per wk): One group started with SSG, whereas other conducted HIIT first half competitive season. After winter break,...

Recovery is essential for high athletic performance, and therefore especially sleep has been identified as a crucial source physical psychological well-being. However, due to early-morning trainings, which are general practice in many sports, athletes likely experience restrictions. Therefore, this study investigated the sleep-wake patterns of 55 junior national rowers (17.7 ± 0.6 years) via logs actigraphy during four-week training camp. stress ratings were obtained every morning with Short...

Assessing current fatigue of athletes to fine-tune training prescriptions is a critical task in competitive sports. Blood-borne surrogate markers are widely used despite the scarcity validation trials with representative subjects and interventions. Moreover, differences between modes disciplines (e.g. due eccentric force production or calorie turnover) have rarely been studied within consistent design. Therefore, we investigated blood-borne during after discipline-specific simulated camps. A...

Stress has been studied extensively in psychology. Only recently, however, research started to address the question of how individuals manage recover from stress. Recovery stress is analyzed as a process self-regulation. Several individual difference variables which affect efficiency self-regulation have integrated into structured model recovery process. Such are action versus state orientation (a tendency ruminate, e.g., about past experience) and volitional components, such...
