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...

J Strength Cond Res 34(1): 192–202, 2020—This study aimed to investigate the impact components (SV) players depending sex age group. A sample best 1,019 (male = 625, female 394) squad German Tennis Federation participated involving complex measurements (body height, body mass, sitting arm span) tests (e.g., SV, medicine ball throws...

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...

The aim of this study was to assess the effect recovery duration in intermittent training drills on metabolism and coordination sport games. Ten nationally ranked male tennis players (age 25.3+/-3.7 years, height 1.83+/-0.8 m, body mass 77.8+/-7.7 kg; mean +/- sx) participated a passing-shot drill (baseline sprint with subsequent passing shot) that aimed improve both starting speed stroke quality (speed precision). Time pressure for preparation individually adjusted by ball-machine...
