AI Article Synopsis
- The study analyzed heart rate variability (HRV) in a professional wheelchair athlete with Charcot-Marie-Tooth disease before and after a marathon, considering the effects of trans-meridian travel.
- Minor reductions in heart rate variability were noted after relocation and on race day, suggesting little impact from travel on cardiac-autonomic activity.
- A significant decrease in HRV was recorded the morning after the marathon, but it returned to baseline within 48 hours, indicating similar responses to those seen in other endurance athletes.
Article Abstract
The purpose of this study was to analyze heart rate variability (HRV) oscillations before and after a marathon which involved trans-meridian air travel and substantial time zone differences in a professional wheelchair athlete with Charcot-Marie-Tooth (CMT) disease. The natural logarithm of the root mean square difference between adjacent normal R-R intervals (Ln rMSSD) was measured daily on the days before, including and following the race. Relative to baseline, small (-3.8 - -4.6%) reductions in LnRMSSD were observed following relocation and on race-day, indicating only minor effects of travel on cardiac-autonomic activity. On the morning following the marathon, a 23.1% reduction in Ln rMSSD was observed, which returned to baseline by 48 h. The race time set by the athlete was the world-leading time in his class. This case study showed that Ln rMSSD responses to marathon in an elite wheelchair athlete with CMT was similar to those previously reported among unrestricted endurance athletes.

Introduction: To determine if athletes with coordination impairment (CI) can continue playing wheelchair rugby (WR), while an evidence-based classification system, including impairment tests for CI is not yet available. This is a defensible practise if they show similar activity limitations as athletes with other eligible impairment types (OI) within the same sports class.
Methods: Standardised activities were measured in 58 elite WR athletes; 14 with CI and 44 with OI.

This study investigated the effects of transcranial photobiomodulation (t-PBM) on para-athletes' manual dexterity and intralimbal coordination. Six para-athletes from a Boccia Team participated. t-PBM was administered using a LED helmet with 204 LEDs (660 and 850 nm) emitting 10 mW each, delivering 9 J/cm per LED during 15-min sessions three times a week.

Elite para athletes with active coping behaviour are less likely to report a sports injury.
Br J Sports Med

Rehabilitation Medicine Research Group, Department of Health Sciences, Lund University, Lund, Sweden.
Objective: Elite para athletes report a high incidence of sports injuries. Research suggests that athletes' strategies to manage adversities may influence the sports injury risk, but knowledge about para athletes' coping behaviours and their association with injuries is limited. The aim was to describe the distribution of coping behaviours in Swedish elite para athletes by sex, age, impairment, sport and to examine associations between coping behaviours and the probability of reporting a prospective sports injury during a 52-week study period.
