Muscle Damage Indicated By Maximal Voluntary Contraction Strength Changes From Immediately To 1 Day After Eccentric Exercise Of The Knee Extensors, Mikio Shoji, Ryoichi Ema, Kazunori Nosaka, Akihiro Kanda, Kosuke Hirata, Ryota Akagi
Research outputs 2014 to 2021
The present study examined if the magnitude of changes in indirect muscle damage markers could be predicted by maximal voluntary isometric contraction (MVIC) torque changes from immediately to 1 day after eccentric exercise. Twenty-eight young men performed 100 maximal isokinetic (60°/s) eccentric contractions of the knee extensors. MVIC torque, potentiated doublet torque, voluntary activation (VA) during MVIC, shear modulus of rectus femoris (RF), vastus medialis and lateralis, and muscle soreness of these muscles were measured before, immediately after, and 1–3 days post-exercise. Based on the recovery rate of the MVIC torque from immediately to 1-day post-exercise, the participants were placed …
Muscle Damage And Performance After Single And Multiple Simulated Matches In University Elite Female Soccer Players, Tai-Ying Chou, Kazunori Nosaka, Trevor C. Chen
Muscle Damage And Performance After Single And Multiple Simulated Matches In University Elite Female Soccer Players, Tai-Ying Chou, Kazunori Nosaka, Trevor C. Chen
Research outputs 2014 to 2021
The present study aimed to compare changes in muscle damage and performance parameters after playing single versus multiple soccer matches to examine fixture congestion effects on performance. Twelve elite female university soccer players performed single, three and six consecutive 90-min bouts of the Loughborough Intermittent Shuttle Test (LIST) with ≥ 12-weeks between conditions in a pseudo-randomized order. Heart rate, blood lactate, rating of perceived exertion and covering distance in each LIST were examined. Changes in several types of muscle damage (e.g., maximal voluntary isometric torque of the knee extensors: MVC-KE) and performance measures (e.g., Yo-Yo Intermittent Recovery Test level 1: …

© 2020 The Authors. Scandinavian Journal of Medicine & Science In Sports published by John Wiley & Sons Ltd This study tested the hypothesis that the magnitude of rectus femoris (RF) damage and the repeated bout effect (RBE) would be greater after knee extensor eccentric exercise performed in a supine (long RF lengths) than a sitting (short RF lengths) position, and the muscle length effects would be more prominent at the proximal than distal RF. Young untrained men were placed to one of the two groups (n = 14 per group). S group performed the knee extensor eccentric exercise in …
