The Force-Velocity Profiling Concept for Sprint Running Is a Dead End
CONCLUSION: At best, force-velocity profiling may be able to identify between-athletes differences. However, these can be more easily deduced directly from performance time traces.PMID:37917955 | DOI:10.1123/ijspp.2023-0110 (Source: International Journal of Sports Physiology and Performance)

Six Weeks of Unilateral Flywheel Hip-Extension and Leg-Curl Training Improves Flywheel Eccentric Peak Power but Does Not Enhance Hamstring Isokinetic or Isometric Strength
CONCLUSION: Unilateral flywheel hamstring training improved knee-flexor eccentric peak power during unilateral flywheel exercise but not flywheel concentric, isokinetic eccentric, or isometric (long-lever) knee-flexor strength.PMID:37917962 | DOI:10.1123/ijspp.2023-0035 (Source: International Journal of Sports Physiology and Performance)

Four Sessions of Repeated-Sprint Cycling Training With or Without Severe Hypoxia Do Not Modify Overground Running Sprint Force-Velocity Profile
CONCLUSIONS: Four sessions of repeated-sprint training either in hypoxia or in normoxia performed over 9 days had no influence on single 50-m overground running sprint performance and associated F-V profile. In world-class female rugby sevens players, the intervention (training camp before an international competition) might have been too short to induce measurable changes. It is also plausible that implementing a similar program in players with likely different F-V profile may result in negligible mechanical effect.PMID:37917965 | DOI:10.1123/ijspp.2023-0112 (Source: International Journal of Sports Physiology and Performance)

Annual Volume and Distribution of Physical Training in Norwegian Female Cross-Country Skiers and Biathletes: A Comparison Between Sports, Competition Levels, and Age Categories-The FENDURA Project
CONCLUSIONS: The higher annual physical training volume by XC skiers compared with biathletes is likely caused by the different demands of the 2 sports; XC skiing necessitates training for 2 skiing styles, while biathlon requires additional shooting practice. However, biathletes compensate with a higher proportion of ski training, particularly in the skating technique.PMID:37917966 | DOI:10.1123/ijspp.2023-0067 (Source: International Journal of Sports Physiology and Performance)

Accuracy of Heart-Rate-Recovery Parameters Assessed From a Wrist-Worn Photoplethysmography Monitor (Polar Unite)
CONCLUSIONS: If a wrist-worn PPG monitor is used to assess HRR, we recommend performing the submaximal-intensity exercise on a bicycle ergometer and focusing on Δ60. Furthermore, to obtain a more accurate Δ60, the time lag between the end of the exercise and the effective decrease in HR should also be considered before the calculation.PMID:37917971 | DOI:10.1123/ijspp.2023-0120 (Source: International Journal of Sports Physiology and Performance)
