“…no backpack). IMT has repeatedly improved wholebody performance in cycling, running, rowing and repeated sprint exercise with improvements of 3-6% (for a review, see HajGhanbari et al, 2013;Illi et al, 2012). Given the improvement we observed here we have demonstrated for the first time that IMT has a genuine ergogenic effect upon 25 kg LC exercise performance.…”

“…Inspiratory muscle training (IMT) has been employed to reduce inspiratory muscle fatigue (for a review, see HajGhanbari et al, 2013;Illi, Held, Frank, & Spengler, 2012). IMT increases the strength of the chest wall inspiratory muscles and the diaphragm (Brown, Johnson, & Sharpe, 2014) with exercise-induced inspiratory muscle fatigue either attenuated (Romer & McConnell, 2004) or unchanged (Verges, Lenherr, Haner, Schulz, & Spengler, 2007).…”

Load carriage (LC) exercise in physically demanding occupations is typically characterised by periods of low-intensity steady-state exercise and short duration, high-intensity exercise while carrying an external mass in a backpack; this form of exercise is also known as LC exercise. This induces inspiratory muscle fatigue and reduces whole-body performance. Accordingly we investigated the effect of inspiratory muscle training (IMT, 50% maximal inspiratory muscle pressure (PImax) twice daily for six week) upon running time-trial performance with thoracic LC. Nineteen healthy males formed a pressure threshold IMT (n = 10) or placebo control group (PLA; n = 9) and performed 60 min LC exercise (6.5 km h(-1)) followed by a 2.4 km running time trial (LCTT) either side of a double-blind six week intervention. Prior to the intervention, PImax was reduced relative to baseline, post-LC and post-LCTT in both groups (pooled data: 13 ± 7% and 16 ± 8%, respectively, p < .05) and similar changes were observed post-PLA. Post-IMT only, resting PImax increased +31% (p < .05) and relative to pre-IMT was greater post-LC (+19%) and post-LCTT (+18%, p < .05), however, the relative reduction in PImax at each time point was unchanged (13 ± 11% and 17 ± 9%, respectively, p > .05). In IMT only, heart rate and perceptual responses were reduced post-LC (p < .05). Time-trial performance was unchanged post-PLA and improved 8 ± 4% after IMT (p < .05). In summary, when wearing a 25 kg backpack, IMT attenuated the cardiovascular and perceptual responses to steady-state exercise and improved high-intensity time-trial performance which we attribute in part to reduced relative work intensity of the inspiratory muscles due to improved inspiratory muscle strength. These findings have real-world implications for occupational contexts.

“…[50] The results of the endurance test have shown that brace diminishes exercise capacity for patients with AIS. [48] These results suggest that it could be helpful to intensively train AIS patients with endurance exercises such as those practiced by athletes [51] in order to reduce oxygen consumption during effort and limit functional disabilities.…”

Spinal orthoses may be considered for improving the walking style, although energy cost does not decline following the orthotic intervention. Implications for Rehabilitations Problems related to scoliosis include reduced quality of life, disability, pain, postural alterations, sensory perturbations, standing instability and gait modifications. Wearing corrective spinal orthoses in AIS subjects produce a reduction in walking speed and cadence, increase in stride length and reduction of gait load asymmetry compared to without brace condition. Spinal orthoses do not decline excessive energy expenditure to walk versus without it.
