The Effects of Apnea Training, Using Voluntary Breath Holds, on High Altitude Acclimation: Breathe-High Altitude Study.
Shah N, Bye K, Marshall A, Woods DR, O'Hara J, Barlow M, Rimmer J, Boos CJ. Shah N, et al. Among authors: o hara j. High Alt Med Biol. 2020 Jun;21(2):152-159. doi: 10.1089/ham.2019.0087. Epub 2020 Apr 8. High Alt Med Biol. 2020. PMID: 32267783 Clinical Trial.
Saturation of arterial oxygen (SpO(2)), heart rate, sleep quality (Insomnia Severity Index [ISI]), rating of perceived exertion (RPE), blood pressure, and Lake Louise scores were measured at SL (in the United Kingdom) and at HA at 1400, 2700, 3400-3700, 4050-4200, 4800, an …

The relationship between anxiety and acute mountain sickness.
Boos CJ, Bass M, O'Hara JP, Vincent E, Mellor A, Sevier L, Abdul-Razakq H, Cooke M, Barlow M, Woods DR. Boos CJ, et al. Among authors: o hara jp. PLoS One. 2018 Jun 21;13(6):e0197147. doi: 10.1371/journal.pone.0197147. eCollection 2018. PLoS One. 2018. PMID: 29927953 Free PMC article.
METHODS: Eighty health adults were assessed at baseline (848m) and over 9 consecutive altitudes during a progressive trek to 5140m. HA-related symptoms (Lake Louise [LLS] and AMS-C Scores) and state anxiety (State-Trait-Anxiety-Score [STAI Y-1]) were examined at each altit …

Changes in balance and joint position sense during a 12-day high altitude trek: The British Services Dhaulagiri medical research expedition.
Clarke SB, Deighton K, Newman C, Nicholson G, Gallagher L, Boos CJ, Mellor A, Woods DR, O'Hara JP. Clarke SB, et al. Among authors: o hara jp. PLoS One. 2018 Jan 17;13(1):e0190919. doi: 10.1371/journal.pone.0190919. eCollection 2018. PLoS One. 2018. PMID: 29342191 Free PMC article.
Data were compared between altitudes and relationships between pulse oximetry, Lake Louise score, and sway velocity were explored. Total sway velocity during standing balance with eyes open (p = 0.003, d = 1.9) and during Sharpened Romberg test with eyes open (p = 0.007, d …

Wilderness medicine at high altitude: recent developments in the field.
Shah NM, Hussain S, Cooke M, O'Hara JP, Mellor A. Shah NM, et al. Among authors: o hara jp. Open Access J Sports Med. 2015 Sep 24;6:319-28. doi: 10.2147/OAJSM.S89856. eCollection 2015. Open Access J Sports Med. 2015. PMID: 26445563 Free PMC article. Review.
In this review, we provide a summary of recent advances of relevance to practitioners who may be advising travelers to altitude. Although the Lake Louise Score is now widely used as a diagnostic tool for acute mountain sickness (AMS), increasing evidence questions the vali …

Rating of perceived exertion and acute mountain sickness during a high-altitude trek.
Mellor AJ, Woods DR, O'Hara J, Howley M, Watchorn J, Boos C. Mellor AJ, et al. Among authors: o hara j. Aviat Space Environ Med. 2014 Dec;85(12):1214-6. doi: 10.3357/ASEM.4083.2014. Aviat Space Environ Med. 2014. PMID: 25479264
Borg Rating of Perceived Exertion (RPE) scores were recorded for the hardest perceived exertion during the day after ascents to 12,576, 14,600, and 16,827 ft (3833, 4450, and 5129 m). Heart rate, Spo2, and Lake Louise Score (LLS) were recorded simultaneously. Statistical t …
