with rest periods between points in female volleyball matches (∼20 [10] s). 2 Therefore, the objective of this study was to compare the adaptive responses of physiological parameters (cardiorespiratory fitness and anaerobic power output) and physical performance with sets of 5-second all-out SSIT
Using Submaximal Exercise Heart Rate for Monitoring Cardiorespiratory Fitness Changes in Professional Soccer Players: A Replication Study
Stefan Altmann, Rainer Neumann, Sascha Härtel, Alexander Woll, and Martin Buchheit
Multistage incremental tests with heart rate (HR) and blood lactate sampling are considered a gold standard method for monitoring cardiorespiratory fitness in elite athletes such as professional soccer players. 1 , 2 However, this method has several limitations, including time-labor (ie, 20–30 min
Reliability of the 30-15 Intermittent Fitness Test in Semiprofessional Soccer Players
Christopher Thomas, Thomas Dos’Santos, Paul A. Jones, and Paul Comfort
Purpose:
The purpose of this investigation was to determine the reliability of the 30-15 Intermittent Fitness Test (30-15IFT) in semiprofessional soccer players.
Methods:
Fourteen male semiprofessional soccer players performed the 30-15IFT on 2 occasions separated by 7 d. Reliability was assessed by intraclass correlation coefficient (ICC), typical error of measurement expressed as a coefficient of variation (CV), and smallest worthwhile change (SWC) to determine any significant difference between testing sessions.
Results:
Maximal intermittent running velocity (VIFT) demonstrated good reliability (ICC = .80) for between-sessions reliability. The CV was 2.5% for between-sessions reliability of the 30-15IFT. As the SWC (0.70 km/h) falls within the range in which the individual’s true score is likely to lie (1.0 km/h), the usefulness of the VIFT was rated as marginal. Despite the usefulness of the 30-15IFT being deemed marginal, a change in performance as small as 1.0 km/h (2 stages) in VIFT could be considered substantial or real.
Conclusion:
This study demonstrates that VIFT in the 30-15IFT is reliable, resulting in a reliable assessment of team-sport-specific cardiorespiratory fitness, with changes as small as 1.0 km/h (2 stages) in VIFT considered meaningful.
Monitoring Cardiorespiratory Fitness in Professional Soccer Players: Is It Worth the Prick?
Martin Buchheit, Ben M. Simpson, and Mathieu Lacome
Purpose: To compare between-tests changes in submaximal exercise heart rate (HRex, 3 min, 12 km/h) and the speed associated with 4 mmol/L of blood lactate (V4mmol) in soccer players to get insight into their level of agreement and respective sensitivity to changes in players’ fitness. Methods: A total of 19 elite professional players (23 [3] y) performed 2 to 3 graded incremental treadmill tests (3-min stages interspersed with 1 min of passive recovery, starting speed 8 km/h, increment 2 km/h until exhaustion or 18 km/h if exhaustion was not reached before) over 1.5 seasons. The correlation between the changes in HRex and V4mmol was examined. Individual changes in the 2 variables were compared (>2 × typical error considered “clear”). Results: The changes in HRex and V4mmol were largely correlated (r = .82; 90% confidence interval, .65–.91). In more than 90% of the cases, when a clear individual change in HRex was observed, it was associated with a similar clear change in V4mmol (the same direction, improvement, or impairment of fitness) and conversely. Conclusions: When it comes to testing players submaximally, the present results suggest that practitioners can use HRex or V4mmol interchangeably with confidence. However, in comparison with a field-based standardized warm-up run (3–4 min, all players together), the value of a multistage incremental test with repeated blood lactate samplings is questionable for a monitoring purpose given its time, labor, cost, and poorer player buy-in.
Physiological and Sprint Kinetics Associated With the Yo-Yo Intermittent Recovery Test Level 1 Performances in Soccer Players

Field sports such as soccer require regular testing to gauge changes in cardiorespiratory fitness (CRF), repeated-sprint ability, agility, and strength, with CRF and strength typically lying on opposite ends of the training continuum. 1 , 2 On the one hand, an improvement in maximal oxygen uptake

The maximal oxygen consumption ( V ˙ O 2 max ) measured during incremental exercise reflects an individual’s cardiorespiratory fitness and is a key determinant of both endurance performance during prolonged exercise and all-cause mortality. 1 In addition to its effects on health and performance
