Despite the acknowledged importance of fatigue on performance, ecologically sound studies investigating fatigue and its effects on sport-specific skills are surprisingly limited. The aim of this study was to investigate the effects of moderate and high-intensity localized muscle fatigue on passing performance in soccer. Twenty physically active male college students (age, 22.9 +/- 5.3 years) participated in this study. Subjects performed the modified Loughborough Soccer Passing Test under the following three conditions: rest, moderate fatigue, and high-intensity fatigue. Fatigue intensity was established using a percentage of the maximal number of alternate split squats performed by the subject in 1 minute. Results revealed a significant difference between performance at rest and performance following high-intensity, localized muscle fatigue. The results suggest the need for trainers and coaches to incorporate high-intensity exercise drills into training plans to help players better cope with the demands of the game on the pitch.

Oxidative stress is augmented under hypoxic environments, which may be attenuated with antioxidant supplementation. We investigated the effects of dietary nitrate (NO-) supplementation combined with high-intensity training performed under hypoxic conditions on antioxidant/pro-oxidant balance. Thirty trained participants were assigned to one of three groups - HNO: hypoxia (13% FO) + NO-; HPL: hypoxia + placebo; CON: normoxia (20.

Article Synopsis
- Researchers investigated how high-intensity laser pulses propagate through a plasma channel by adjusting its length, successfully guiding 500 terawatt pulses over distances of 30 cm in hydrogen plasma.
- They observed the initial energy transfer involving higher-order modes and a transition to more efficient propagation, noting a depletion of laser energy that generates wakefields.
- Utilizing 21.3 joules of laser energy for localized electron injection, they achieved electron bunches with nearly monenergetic peaks reaching 9.2 GeV and total charge exceeding 10 GeV.

This paper describes the design and initial proof-of-concept of a single pre-clinical transcranial focused ultrasound (FUS) system capable of performing histotripsy (mechanical ablation), hyperthermia, blood-brain barrier opening (BBBO), sonodynamic therapy, or neuromodulation in a murine brain. We have termed it the All-in-One FUS system for murine brain studies, which is the first FUS system of its kind. The 1.
