A Thorax Marker Set Model to Analyse the Kinematics of Walking Without the Need to Place Markers on the Back

Journal of Biomechanical Engineering (2020)

Eva Orantes-González José María Heredia Jiménez Ambreen Chohan Jim Richards

Abstract Background: Previous thorax models have been proposed for gait analysis, however these require markers to be placed on the back. This presents a limitation in the kinematic analysis of the thorax under load carriage conditions. Research question: This study evaluated the validity and reliability of a thorax marker set that does not require markers to be placed on the back (HubemaLab model) when compared to 3 previously published marker set models. Methods: 17 young adults were evaluated while walking at their self-selected speed. A 12 camera motion capture system was used to acquire the marker position data which was then processed using the respective models using Visual-3D. The level of agreement for the flexion/extension peak, right/left lateral peak and right/left rotation peak of the thorax angle and angular velocity; together with the range of motion and thorax angular velocities in the three planes was found between each thorax marker set, while the reliability was measured using the intraclass correlation coefficient. Results: The ICC results for the thorax angle ROM and the range of thorax angular velocity between the HubemaLab model and the other models showed excellent to good reliability in all three planes. While the ICCs for the peak flexion/extension, peak right/left lateral flexion and peak right/left rotation showed excellent to moderate reliability in all three planes. Conclusion: The new model could be potentially valuable for kinematic gait analysis under load carriage conditions which obscure markers placed on the back.

Supplementary Material for: Skeletal Muscle Tissue Trib3 Links Obesity with Insulin Resistance by Autophagic Degradation of AKT2

Figshare (2018)

Min‐Jung Kwon Joong Sik Eom Doyeon Kim Jae Hyeon Kim José María Heredia Jiménez

Background/Aims: Obesity is a serious health risk factor strongly associated with insulin resistance and type 2 diabetes; however, the underlying mechanisms associating obesity with insulin resistance remain unknown. In this study, we explored the physiological role of Trib3 in regulating glucose metabolism in skeletal muscle tissues in a Trib3 transgenic mice model. Methods: Glucose metabolism in transgenic mice overexpressing Trib3 specifically in the skeletal muscle was examined by glucose/insulin tolerance test, metabolic cage studies, and glucose uptake assay. The effect of Trib3 overexpression on AKT phosphorylation and AKT protein turnover were assessed by RT-PCR and immunoblot analysis. Subcellular distribution of Trib3 and AKT1/2 was determined by microscopic analysis, co-immunoprecipitation experiments, and limited-detergent extraction of subcellular organelles. Ubiquitin assay was performed and ATG7 deficient cell line was employed to address the mechanisms of Trib3-dependent AKT protein homeostasis. Results: We found that Trib3 expression in skeletal muscle is elevated in obese conditions, and transgenic mice that overexpressed Trib3, specifically in skeletal muscle tissues, displayed impaired glucose homeostasis by suppressing insulin-stimulated glucose uptake. Disruption of insulin signaling in skeletal muscle Trib3 transgenic mice may occur due to the specific downregulation of AKT2 but not AKT1. Autophagy regulated AKT2 protein turnover, and Trib3 overexpression stimulated autophagic degradation of AKT2 by promoting AKT2 ubiquitination. Conclusion: Because diet-induced obesity upregulates Trib3 and downregulates AKT2 in skeletal muscle tissues, Trib3 may play a key role in establishing an association between obesity and insulin resistance by regulating AKT2 protein homeostasis.

Chronic Effects of a Training Program Using a Nasal Inspiratory Restriction Device on Elite Cyclists

International Journal of Environmental Research and Public Health (2021)

José Luis González Montesinos Jorge R. Fernández‐Santos Carmen Vaz Pardal Rubén Aragón-Martín Aurelio Arnedillo Muñoz

This study compared the response of a 9-week cycling training on ventilatory efficiency under two conditions: (i) Combined with respiratory muscle training (RMT) using a new nasal restriction device (FeelBreathe) (FB group) and (ii) without RMT (Control group). Eighteen healthy elite cyclists were randomly separated into the FB group (n = 10) or Control group (n = 8). Gas exchange was measured breath by breath to measure ventilatory efficiency during an incremental test on a cycloergometer before (Pre) and after (Post) the nine weeks of training. The FB group showed higher peak power (Δ (95%HDI) (0.82 W/kg (0.49, 1.17)), VO2max (5.27 mL/kg/min (0.69, 10.83)) and VT1 (29.3 W (1.8, 56.7)) compared to Control at PostFINAL. The FB group showed lower values from Pre to PostPRE in minute ventilation (VE) (−21.0 L/min (−29.7, −11.5)), Breathing frequency (BF) (−5.1 breaths/min (−9.4, −0.9)), carbon dioxide output (VCO2) (−0.5 L/min (−0.7, −0.2)), respiratory equivalents for oxygen (EqO2) (−0.8 L/min (−2.4, 0.8)), heart rate (HR) (−5.9 beats/min (−9.2, −2.5)), respiratory exchange ratio (RER) (−0.1 (−0.1, −0.0) and a higher value in inspiratory time (Tin) (0.05 s (0.00, 0.10)), expiratory time (Tex) (0.11 s (0.05, 0.17)) and end-tidal partial pressure of CO2 (PETCO2) (0.3 mmHg (0.1, 0.6)). In conclusion, RMT using FB seems to be a new and easy alternative ergogenic tool which can be used at the same time as day-to-day training for performance enhancement.
