This leads to exercise intolerance and poor physical activity. Previous studies reveal that breathing with positive expiratory pressure (PEP) can reduce dyspnea at rest and breathing with Conical-PEP device (C-PEP) during exercise can increase exercise endurance. However, the device is not practical to be used during exercise with mobility and daily life. We, therefore, has developed a new PEP device, C-PEP mask, and aimed to evaluate the effects of breathing with C-PEP mask during exercise on exercise tolerance exertional dyspnea and cardiorespiratory function in moderate to severe COPD patients. A randomized cross-over trial was conducted in 9 COPD participants with an average age of 67.3 ± 3.9 years. The participants performed Spot Marching exercise test at the average speed of 90±15 step/min with (C-PEP) and without C-PEP mask (control) until symptom limited by severe dyspnea or heart rate (HR) reaching 80%HRmax. Exercise duration was recorded. Dyspnea HR, respiratory rate (RR), end tidal carbondioxide pressure (PETCO2), pulse oxygen saturation (SpO2), arrhythmia and blood pressure were examined at pre- , during,&nbsp; immediate post &nbsp;and 10 minute of recovery except BP was not measured during exercise. The results showed that the participants could exercise 4 minutes longer in C-PEP than Control (12.2 ± 5.8&nbsp; v.s&nbsp; 8.3 ± 2.1 minutes;<em>&nbsp;p</em>&lt; 0.05) whilst they &nbsp;stopped the exercise at similar levels of dyspnea and HR (80% HRmax) in both conditions (RPB 4.6 ± 2.7/10 &nbsp;vs 4.1 ± 1.8 /10unit and HR at 106.2 ± 8.4&nbsp; vs 108.5 ± 11.7 bpm (in C-PEP and control condition respectively) RR was slower in C-PEP than Control during the exercise (AUC median IQR 25-75 in CPEP vs Control respectively p= 0.26) &nbsp;At the end of exercise, RR slower and VT greater in C-PEP vs Control (24.0±6.0 vs&nbsp;&nbsp;&nbsp;&nbsp; 28.0± 3.0breaths/min &nbsp;and 1017.8±189.0&nbsp; vs 974.4±279.1 ml&nbsp; respectively p = 0.42). No arrhythmia was observed and P<sub>ET</sub>CO<sub>2</sub>&nbsp;and SpO<sub>2</sub>&nbsp;were normal during exercise in both conditions. RR returned to rest in C-PEP but not in Control and HR and BP were still higher than resting in both conditions at the end of the 10 min recovery period. We conclude that using a C-PEP mask during exercise is safe, reduces exertional dyspnea increases exercise tolerance and promotes recovery of lung function in COPD. Therefore, C-PEP mask could be used during exercise training in pulmonary rehabilitation and physical activity in moderate to severe COPD.&nbsp;</p> Malipond Pukdeechat Chatchai Phimphasak Chulee Jones ##submission.copyrightStatement## 2017-12-16 2017-12-16 39 3 97 110 The effects of very high stimulation frequency on fatigue of the quadriceps femoris muscle in healthy participants: A pilot study <p>Background: The main limitation of neuromuscular electrical stimulation (NMES) is the muscle fatigue. According to previous studies, stimulation frequency has the greatest influence on rate of muscle fatigue. However, most of studies have been focused on high stimulation frequency but less than 100 Hz. We proposed that using a very high frequency may produce asynchronous motor unit recruitment and similar or less muscle fatigue.<br>Objectives: To examine the effects of very high (150 and 200 Hz) and low (50 Hz) stimulation frequencies on the declining stimulated muscle force.<br>Methods: Nine healthy participants underwent a fatigue test using 3 stimulation frequencies (50, 150, and 200 Hz) combined with wide pulse duration (0.9 ms) for 15 minutes fatigue test. Muscle fatigue was assessed using the normalized force values at the end of each stimulation frequency protocol.<br>Results: No difference in muscle fatigue was found when compared between very high frequency (150-200 Hz) and low frequency (50 Hz) combined with wide pulse duration conditions during a 15-minute fatigue test.<br>Conclusion: This study demonstrated that both very high and low frequencies combined with wide pulse duration showed no differences in muscle fatigue. Further studies with a larger sample size are needed for confirmation.</p> Kitima Rongsawad Jonjin Ratanapinunchai ##submission.copyrightStatement## 2017-12-16 2017-12-16 39 3 111 119 Height loss <p>Height loss is caused by spinal loading activities in daily life. Deformation and dehydration of the intervertebral discs are physically changes from the loading on spine. It finds that human height is gradually decreased during the daytime approximately 1.1% of total body height, which is mostly attributable changing at lumbar disc. However, the recumbent position can reduce loading on the spine and intra-discal osmotic pressure, thus spinal fluid return into the intervertebral discs. For this reason, the normal height level is considerately restored, however levels of height loss are depended on influence factors. Once the factors affected height loss with statistically significance, it possibly caused permanent distortion of intervertebral disc in consequence of low back pain. Low back pain also has an impact on the quality of life and economic burden. Therefore, this review article concluded about knowledge of structures and biomechanics of the intervertebral disc, and influence factors significantly affected to height loss. The main objective is to promote awareness of the activities and influence factors that affected height loss significantly during the day, and this may cause low back pain in the future.</p> Pongsatorn Saiklang Rungthip Puntumetakul Manida Swangnetr Orawan Buranruk Wantana Siritaratiwat Suwalee Namwongsa Wantanee Yodchaisarn ##submission.copyrightStatement## 2017-12-16 2017-12-16 39 3 120 133
