The effects of ten weeks resistance training on sticking region in chest-press exercises.

ABSTRACT: The aim of the study was to compare the effects of a 10-week chest-press resistance training on lifting regions in a trained exercise and a none-trained exercise; the barbell bench press (BBP). Thirty-five resistance trained men with 4.2 (± 2.3) years of resistance training experience were recruited. The participants were randomized to attend a resistance program, performing the chest-press, twice per week using either, Smith machine, dumbbells or laying on Swiss ball using a barbell. A six-repetitions maximum (6RM) test was conducted pre- and post-training in the trained chest-press exercise and non-trained BBP to examine lifting velocity, load displacement and the time of the pre-sticking, sticking and post-sticking regions. Additionally, the muscle activity in pectoralis major, triceps brachii, biceps brachii and deltoid anterior was examined. In the post-test, all three chest-press groups decreased lifting velocity and increased the time to reach the sticking- and post-sticking region. Independent of the type of chest-press exercise trained, no differences were observed in vertical displacement or in the muscle activity for the three lifting regions. In general, similar changes in kinematics in trained exercise and those observed in the BBP were observed for all three groups. This indicates that none of the three chest-press exercises (Swiss ball, Smith machine or dumbbells) were specific regarding the lifting regions but displaced a transferability towards the non-trained BBP. However, improved strength altered the sticking region among resistance trained men.

Project description:ImportanceClinical practice guidelines support exercise for patients with Parkinson disease (PD), but to our knowledge, no randomized clinical trials have tested whether yoga is superior to conventional physical exercises for stress and symptom management.ObjectiveTo compare the effects of a mindfulness yoga program vs stretching and resistance training exercise (SRTE) on psychological distress, physical health, spiritual well-being, and health-related quality of life (HRQOL) in patients with mild-to-moderate PD.Design, setting, and participantsAn assessor-masked, randomized clinical trial using the intention-to-treat principle was conducted at 4 community rehabilitation centers in Hong Kong between December 1, 2016, and May 31, 2017. A total of 187 adults (aged ≥18 years) with a clinical diagnosis of idiopathic PD who were able to stand unaided and walk with or without an assistive device were enrolled via convenience sampling. Eligible participants were randomized 1:1 to mindfulness yoga or SRTE.InterventionsMindfulness yoga was delivered in 90-minute groups and SRTE were delivered in 60-minute groups for 8 weeks.Main outcomes and measuresPrimary outcomes included anxiety and depressive symptoms assessed using the Hospital Anxiety and Depression Scale. Secondary outcomes included severity of motor symptoms (Movement Disorder Society Unified Parkinson's Disease Rating Scale [MDS-UPDRS], Part III motor score), mobility, spiritual well-being in terms of perceived hardship and equanimity, and HRQOL. Assessments were done at baseline, 8 weeks (T1), and 20 weeks (T2).ResultsThe 138 participants included 65 men (47.1%) with a mean (SD) age of 63.7 (8.7) years and a mean (SD) MDS-UPDRS score of 33.3 (15.3). Generalized estimating equation analyses revealed that the yoga group had significantly better improvement in outcomes than the SRTE group, particularly for anxiety (time-by-group interaction, T1: β, -1.79 [95% CI, -2.85 to -0.69; P = .001]; T2: β, -2.05 [95% CI, -3.02 to -1.08; P < .001]), depression (T1: β, -2.75 [95% CI, -3.17 to -1.35; P < .001]); T2: β, -2.75 [95% CI, -3.71 to -1.79; P < .001]), perceived hardship (T1: β, -0.92 [95% CI, -1.25 to -0.61; P < .001]; T2: β, -0.76 [95% CI, -1.12 to -0.40; P < .001]), perceived equanimity (T1: β, 1.11 [95% CI, 0.79-1.42; P < .001]; T2: β, 1.19 [95% CI, 0.82-1.56; P < .001]), and disease-specific HRQOL (T1: β, -7.77 [95% CI, -11.61 to -4.38; P < .001]; T2: β, -7.99 [95% CI, -11.61 to -4.38; P < .001]).Conclusions and relevanceAmong patients with mild-to-moderate PD, the mindfulness yoga program was found to be as effective as SRTE in improving motor dysfunction and mobility, with the additional benefits of a reduction in anxiety and depressive symptoms and an increase in spiritual well-being and HRQOL.Trial registrationCentre for Clinical Research and Biostatistics identifier: CUHK_CCRB00522.
