“…Pushing and pulling involve a substantial amount of muscle and metabolic activity in the trunk and other body regions of workers. 31,56 However, the physiological contribution from these regions, in particular from lumbar muscles in terms of oxygenation and blood volume changes during pushing and pulling, are still limited in the literature (Table 2). An example of repetitive pushing and pulling task and typical trends of oxygenation and blood volume responses (from right erector spinae and biceps) in a male participant are demonstrated in Figure 3.…”

The potential application of near infrared (NIR) spectroscopy has opened doors for many research investigations related to occupational health, specifically in low back muscle research. This review addressed haemodynamic measurements of paraspinal muscles within the context of low back musculoskeletal health and disorders. Systematic online English language searches were conducted using MEDLINE, EMBASE, ScienceDirect and Scopus. A study was included if it was focused on NIR spectroscopy application to the back region and was also published in the English language. A study was excluded if the main focus was either on upper/lower extremity specific investigations, or the experimental protocol was ambiguous, or the measures utilised were other than spectroscopy-derived haemodynamics. In total, 37 low back studies were included in the review. Studies were mainly classified into five categories: (i) postural variation, (ii) occupational exposure, (iii) aetiology of low back disorders, (iv) analysis of adipose tissue thickness on spectroscopy-derived measurements and (v) reliability of optical spectroscopy measurements. Seventeen studies were focused on the basic (patho)physiology of the low back musculature during a variety of postural variations. Thirteen studies were specific to occupational activities, whereas 10 investigations were related to low back musculoskeletal disorders. Nine studies examined the influence of adipose tissue thickness measured at the erector spinae region on haemodynamic responses. Reliability of spectroscopy-derived responses was reported in 10 studies. This systematic review supports the need for more spectroscopy-related investigations relevant to work-related activities and specific to low back musculoskeletal disorders. Rigorous statistical analysis is needed in examining the influence of adipose tissue thickness on haemodynamic responses. Although high reliability of spectroscopy-derived responses was found in the majority of studies, to date there are no investigations that have established their reliability in the low back pain patient population. More importantly, a proper calibration technique to identify the physiological minimum in the paraspinal muscle region is still elusive. Overall, understanding injury mechanisms for low back pain and other associated musculoskeletal disorders with NIR oximeters is still in its infancy. However, with the advent of advanced optical spectroscopy systems in the last decade, the potential for innovative use of NIR oximeters in low back musculoskeletal health-related research is promising.

“…The present study aimed to investigate whether a 7-weeks low intensity (30% heart rate reserve; HRR) handcycle training with a norm duration (30 min/session) can induce favourable effects in physical capacity of able-bodied untrained female subjects, thus simulating to some extent training effects in wheelchair users in early rehabilitation (Flandrois et al, 1986;Maikala & Bhambhani, 2006). Based on the results of previous studies (De Groot et al, 2008;Van den Berg et al, 2010), we hypothesized that a low-intensity (30% HRR) norm duration handcycle training program would improve mobility related parameters such as peak power output and submaximal efficiency.…”

This study evaluated the effect of a low-intensity norm duration synchronous handcycle wheelchair training in untrained able-bodied women. The training group (n = 9) received 7-weeks of low-intensity upper body training in an instrumented handcycle on a motor-driven treadmill (MDT), 3 × 30 min/week at 30% heart rate reserve. The control group (n = 10) received no training. Incremental handcycle tests on the MDT were used to determine peak values for oxygen uptake (VO 2peak ), power output (PO peak ), heart rate (HR peak ), minute ventilation (V Epeak ), and respiratory exchange ratio (RER peak ), submaximal values for heart rate (HR), oxygen uptake (VO 2 ) and gross efficiency (GE) before and after training. Local perceived discomfort and rate of perceived exertion (RPE) were also assessed. Training significantly improved PO peak (+20%), HR peak (+3%), RER peak (+5%), submaximal GE (+21%), VO 2 (−20%), V E (−33%), HR (−12%) and RPE was low (7.1 ± 0.5) (p < 0.05). No effects were found in VO 2peak and V Epeak (p > 0.05). Though VO 2peak did not improve, low-intensity norm duration handcycling training improved handcycling PO peak , while RPE was low. Also, GE increased, suggesting a motor control improvement. Handcycle training seems to be an appropriate exercise mode to improve physical capacity, and prevent early fatigue and overuse in untrained individuals.

“…Perception of effort is widely investigated during global locomotor tasks, such as walking or cycling, in both healthy and symptomatic populations (Au et al, 2017;Décombe et al, 2020;Flairty & Scheadler, 2020;Horstman et al, 1979;Zinoubi et al, 2018) to prescribe and monitor exercise (Azevedo et al, 2016;Eston & Parfitt, 2018;Impellizzeri et al, 2004). Perception of effort is also investigated during isolated motor tasks involving the upper or lower limb, in strength training program (Miller et al, 2009;Zourdos et al, 2016), in studies aiming at better understanding the regulation of endurance performance (Maikala & Bhambhani, 2006;Pageaux et al, 2013) or the mechanisms associated with the development of muscle fatigue during repetitive tasks Jacquet et al, 2021;Otto et al, 2019;Yang et al, 2019). To the best of our knowledge, most of the studies investigating perception of effort are performed during locomotor exercises or isolated exercises performed with the lower limbs (de Morree et al, 2014;Faelli et al, 2019;Luu et al, 2016;Meir et al, 2015).…”

PURPOSE: The perception of effort (PE) is widely used to prescribe and monitor exercise during locomotor and resistance tasks. The present study examines the validity of PE to prescribe and monitor exercise during upper-limb motor tasks under various loads and speed requirements.METHODS: Forty participants volunteered in two experiments. In experiment 1, we used four PE intensities to prescribe exercise on a modified version of the box and block test (BBT) and a pointing task. We investigated the possibility of monitoring the exercise intensity by tracking changes in PE rating in response to three different tempos or additional weights. Experiment 2 replicated the possibility of prescribing the exercise with the PE intensity during the BBT and explored the impact of additional weights on performance and PE during the standardized version of the BBT. Muscle activation, heart rate and respiratory frequencies were recorded.RESULTS: In experiment 1, increasing the PE intensity to prescribe exercise induced an increased performance between each intensity. Increasing task difficulty with faster movement tempo and adding weight on the forearm increased the rating of PE. Experiment 2 replicated the possibility to use PE intensity for exercise prescription during the BBT. When completing the BBT with an additional weight on the forearm, participants maintained performance at the cost of a higher PE. In both experiments, changes in PE are associated with changes in muscle activation. CONCLUSION: Our results suggest that PE is a valid tool to prescribe and monitor exercise during upper-limb motor tasks.
