Mucosal immune responses to treadmill exercise in elite wheelchair athletes

REA Auditado

Purpose: The study’s purpose was to examine salivary secretory
immunoglobulin A (sIgA) responses and >-amylase activity after constant load and intermittent exercise in elite wheelchair athletes.
Methods: Twenty-three wheelchair athletes divided into three groups (eight tetraplegic (TETRA), seven paraplegic, and eight non–spinal
cord–injured) performed two randomized and counterbalanced 60-min sessions on a treadmill. These consisted of constant load (60%
peak oxygen uptake) and intermittent (80% and 40% peak oxygen uptake) exercise blocks.

Submaximal exercise responses in tetraplegic, paraplegic and non spinal cord injured elite wheelchair athletes

REA Auditado

It remains unclear whether similar exercise prescription, based on physiological markers, can be applied to subgroups of wheelchair athletes with different disabilities. Therefore, 25 wheelchair athletes, divided into three subgroups [eight tetraplegic (TETRA), nine paraplegic (PARA) and eight non spinal cord injured (NON-SCI)], performed an exercise test consisting of incremental submaximal stages, covering a range from 40% to 80% peak oxygen uptake (%V̇O2peak).

Mucosal immune responses during court training in elite tetraplegic athletes

REA Auditado

Study design: Experimental study.
Objectives: To examine salivary secretory immunoglobulin A (sIgA) responses and a-amylase activity during court training in highly
trained tetraplegic athletes.
Setting: Loughborough, UK.
Methods: Seven highly trained wheelchair rugby athletes with tetraplegia performed two separate wheelchair rugby court training
sessions, lasting 23 and 41.5min, respectively, with either an aerobic or an interval focus. Timed, unstimulated saliva samples were
obtained pre, post and 30min post exercise and analysed for sIgA and a-amylase.

Salivary immunoglobulin A and upper respiratory symptoms during 5 months of training in elite tetraplegic athletes

REA Auditado

Purpose: Altered autonomic innervation in tetraplegic individuals has been shown to depress certain immune parameters at rest and alter exercise-related salivary immunoglobulin A (sIgA) responses. The purpose of this study was to examine resting sIgA responses as a function of training load and episodes of upper respiratory symptoms (URS) in elite tetraplegic athletes. Methods: Resting saliva samples were obtained from 14 tetraplegic athletes at 12 predefined time points over 5 months and analyzed for sIgA.
