Measurement of maximum oxygen consumption at tissue level (VO2 max) using cardiopulmonary exercise testing (CPET) is considered the gold standard in evaluating physiological fitness of an athlete. No such testing had been conducted on Sri Lankan national level rowers up to date. With this background the aim of this study was to evaluate the physiological profile of national rowers of Sri Lanka to assess the state of their cardiopulmonary fitness. Anthropometrical and physiological profiles were created for 22 rowers (10 males and 11 females). The Shapiro-Wilcoxon test was used to check the normal distribution. Means and standard deviations of the parameters were calculated. A P value less than 0.05 was considered to be statistically significant. Twenty rowers achieved more than 90% of their predicted HR and one achieved a HR of more than 85% indicating a maximum effort by the entire group. The average work rate achieved by oarsmen were 231 W, which is an average of 82% of the predicted. The average HR achieved was 187 BPM, which corresponds to an achievement of 96% of the predicted. The average respiratory exchange ratio achieved by oarsmen were 0.96, an indication of anaerobic glycolysis at peak exercise. Oarswomen achieved a peak workload of 235 which is slightly more than oarsmen. This is an achievement of 81% of the predicted. The group average HR achieved by oarswomen was 95 BPM, which is an achievement of 95% of the predicted. The group average RER was 0.84 which indicates a mixture of aerobic and anaerobic glycolysis at peak exercise. The VO2 values obtained by Sri Lankan rowers are low compared to international standards. Despite the overall lower VO2 max obtained by male rowers, their VO2 at AT was at a higher percentage of their peak VO2, indicating better cardiovascular fitness. Cardiovascular exercise can be improved to achieve a higher VO2 with a lower HR through threshold training in order to improve performance and uplift the stranded of rowing in Sri Lanka.

“…On day one, the participants undertook a 6 MWT to determine their functional (walking) capacity), in line with the ATS guidelines [9]. On the second day, they were asked to complete an incremental bicycle exercise test on a stationary bicycle (ergometer) (VIAsprint™ 150P Ergometer, Vyaire Medical, IL, USA) in accordance with methods described by McNarry et al [10], Arena et al [11] and Senanayake et al [12].…”

Idiopathic pulmonary fibrosis (IPF) is a chronic, life-limiting with an average life expectancy of 05 years following the onset of the disease, with no curative treatments. These patients need palliative care and rehabilitation is one of the methods that can be used to improve quality of life (QoL) among these patients. Yet the research conducted to assess benefits of pulmonary rehabilitation (PR) in terms of improving physical activity and QoL in IPF patients remains limited. Hence this study aims to evaluate the effect of a bespoke pulmonary rehabilitation programme, on the physical, physiological and psychological parameters and improvements of QoL among IPF patients. Eleven (11) subjects with IPF received 6 weeks of pulmonary rehabilitation. An interviewer administered quality of life questionnaire, six-minute walking test (6MWT), Incremental bicycle exercise tests were performed, and cardiac and respiratory parameters were assessed pre-and post-rehabilitation. The 6MWT was significantly increased following training (Pre 312.55 ± 89.99; Post, 380.73 ± 59.60). A significant improvement was observed in overall QoL (2.226 ± 0.026), dyspnoea (−0.455 ± 0.004) anxiety (−2.070 ± 0.038), depression (−2.217 ± 0.027) scores. No significant changes were found in the VO 2 max and other cardiopulmonary parameters, while non-significant improvement was seen in SpO 2 at peak exercise from 85.8-86.5.

“…Idiopathic Pulmonary Fibrosis (IPF) is a chronic, irreversible and progressive disease that causes the development of scars in the lung tissues [1]. The root cause of this is unknown and it causes fibrosis in alveolar walls which leads to gas exchange impairment leading to decline in respiratory function and death from respiratory failure [2].…”

Background: Idiopathic Pulmonary Fibrosis (IPF) is a chronic, progressive, and life-limiting condition. It has no cure hence it is vital to establish effective methods of improving the quality of remaining life in these patients. One of the key components of improving quality of life is pulmonary rehabilitation. However little research has been conducted to understand the perspectives and lived experience of people with IPF on pulmonary rehabilitation. Hence, we aim to fill this gap in the existing literature. Methods: We sought to understand how patients coped with pulmonary rehabilitation. A patient-centred approach was used to explore the physical and psychological impact of pulmonary rehabilitation. Semi-structured interviews were conducted by experienced academics. Interviews used a topic guide but mostly led by the participants. An inductive thematic approach was used to analyse data, allowing us to identify common themes in the participants' experiences. Results: Of fifty invited participants, ten took part in the study (aged 53 -81 years). Inductive analysis of interviews identified seven second-order themes and eleven first-order themes, represented by two General Dimensions: "motivation" and "Advantages and disadvantages". Overall, participants found the pulmonary rehabilitation programme to be useful and they experienced an increase in their quality of life following rehabilitation.
