Limitations of maximal oxygen uptake during whole-body exercise

open access: yes, 2007
Oxygen uptake increases linearly with increased running speed or rate of work and finally reaches a maximum beyond which no effort can drive it further. This phenomenon is referred to as the plateau in oxygen uptake .

Tailoring Li‐ion Storage and Transport in Two‐Dimensional Conjugated Metal‐Organic Frameworks via Precise Nitrogen Incorporation

open access: yesAdvanced Functional Materials, EarlyView.
Two nitrogen‐doped 2D conjugated metal‐organic frameworks (2D c‐MOFs, namely Cu‐Nx‐OHBA, x = 2 or 4) are synthesized, featuring precise nitrogen incorporation via rational ligand design. The Cu‐Nx‐OHBA 2D c‐MOFs are largely tailorable by varying skeletal nitrogen density, with respect to electrical conductivity, Li‐storage capacitance, and Li‐transport

Effect of Hypoxia on the Oxygen Uptake Response to an Exhaustive Severe Intensity Run

open access: yes
It has been shown that highly aerobically trained individuals are unable to achieve maximal oxygen uptake (O2 max) during exhaustive running lasting ~2 min despite sufficient time for the response (Draper and Wood, 2005).

Familial Relationships in Maximal Oxygen Uptake

open access: yes, 2020
The Tecumseh, Michigan Community Health Study provided an opportunity to study the familial relationships in maximal oxygen uptake capacity (VO 2 max). A total of 1066 males and 119 females, age 10-69 were given a multi-staged treadmill test.

BICYCLE ERGOMETER MEASUREMENT OF MAXIMAL OXYGEN UPTAKE IN CHILDREN

open access: yes, 1967
Seven to 15 maximal exercise tests on a cycle ergometer were done on twenty boys, 11 to 15 years of age, until the work load was sufficiently high that it could not be sustained for 3 min.

Mechanoluminescent HOF Nanotransducers Enabled Sono‐Optogenetics in Parkinsonian Rats

open access: yesAdvanced Functional Materials, EarlyView.
We present a mechanoluminescent system utilizing porous hydrogen‐bonded organic frameworks (HOFs) as a toolkit for focused ultrasound‐triggered, non‐invasive light delivery to the deep brain in rats. This approach enables the specific activation of PV‐GPe neurons in dopamine‐depleted Parkinson's disease rat models, resulting in a comparable alleviation

Magnetic‐Field Control of Surface States in CoFe2O4 Thin Films for Nitrate Electroreduction to Ammonia

open access: yesAdvanced Functional Materials, EarlyView.
Magnetic‐field‐assisted CVD of heterometallic single‐source precursors modulates thin‐film surface electronic structure and interfacial charge transfer. Field‐grown (Cobalt ferrite‐1T)CF‐1T films exhibit stabilized electronic states, lower kinetic barriers, and markedly enhanced nitrate‐to‐ammonia electrocatalysis versus (Cobalt ferrite‐0T) CF‐0T ...
