Abstract Funding Acknowledgements Type of funding sources: None. Cardiac rehabilitation (CR) has well known beneficial effects on physical capacity, health-related quality of life, morbidity and mortality following an acute cardiac event. It is also known that smoking status is a powerful predictor of recurrent cardiovascular disease events. However, it has been noted that smoker patients may be less likely to access or complete CR. The aim of this study was to determine the levels of anxiety and depression and its improvement, depending on the smoking status of patients with coronary artery disease (CAD) on phase 2 of the Cardiac Rehabilitation Program (CRP). Additionally, we intend to investigate the mental health impact on smoker patients" group in conventional CR versus telemonitored CR. A retrospective study was conducted and patients in CRP between 2017 and 2020 were included. Patient selection and information collection were obtained through medical records. The outcomes of anxiety and depression were evaluated through the Hospital Anxiety and Depression Scale (HADS). Patients were divided into two groups: group 1 for non-smokers or ex-smokers and group 2 for smokers. For group 2 patients, a sub-analysis was performed for patients following the conventional CR versus the telemonitored CR, with the use of MOVIDA mobile application. Variables were analysed in the beginning (T0) and in the end (T1) of phase 2, around 3 months after. Group comparisons tests and statistical analysis were performed using SPSS software v25.0. A p-value less than 0.05 is statistically significant.  We analysed 107 patients, which 93 of these were assiduous and 69 concluded the phase 2 of CRP: 39 patients in group 1 and 30 patients in group 2. Two groups have similar baseline characteristics, except for the higher presence of diabetes (p = 0.02) in group 1. It was noted an improvement in both anxiety and depression items for group 1 (p < 0.01 for both), but only for anxiety item for group 2 (p = 0.03). In subgroup analysis, we observed no improvement for smoking patients following the conventional CR for both anxiety and depression items (p = 0.60 and p = 0.71, respectably) versus a significant difference in telemonitored CR patients (p = 0.02 and p = 0.04). We hypothesise that, when compared to conventional CR, cardiac telemonitored exercise using modern communication methods may result in an improved mental health state among smoking patients, which can lead to a better adherence for CRP. Further studies including more patients and phase 3 of CRP are needed to confirm these results.

This study was aimed to: (1) investigate the effects of physiological functions of sprint interval training (SIT) on the aerobic capacity of elite badminton players; and (2) explore the potential mechanisms of oxygen uptake, transport and recovery within the process. Thirty-two elite badminton players volunteered to participate and were randomly divided into experimental (Male-SIT and Female-SIT group) and control groups (Male-CON and Female-CON) within each gender. During a total of eight weeks, SIT group performed three times of SIT training per week, including two power bike trainings and one multi-ball training, while the CON group undertook two Fartlek runs and one regular multi-ball training. The distance of YO-YO IR2 test (which evaluates player’s ability to recover between high intensity intermittent exercises) for Male-SIT and Female-SIT groups increased from 1083.0 ± 205.8 m to 1217.5 ± 190.5 m, and from 725 ± 132.9 m to 840 ± 126.5 m (p < 0.05), respectively, which were significantly higher than both CON groups (p < 0.05). For the Male-SIT group, the ventilatory anaerobic threshold and ventilatory anaerobic threshold in percentage of VO2max significantly increased from 3088.4 ± 450.9 mL/min to 3665.3 ± 263.5 mL/min (p < 0.05),and from 74 ± 10% to 85 ± 3% (p < 0.05) after the intervention, and the increases were significantly higher than the Male-CON group (p < 0.05); for the Female-SIT group, the ventilatory anaerobic threshold and ventilatory anaerobic threshold in percentage of VO2max were significantly elevated from 1940.1 ± 112.8 mL/min to 2176.9 ± 78.6 mL/min, and from 75 ± 4% to 82 ± 4% (p < 0.05) after the intervention, which also were significantly higher than those of the Female-CON group (p < 0.05). Finally, the lactate clearance rate was raised from 13 ± 3% to 21 ± 4% (p < 0.05) and from 21 ± 5% to 27 ± 4% for both Male-SIT and Female-SIT groups when compared to the pre-test, and this increase was significantly higher than the control groups (p < 0.05). As a training method, SIT could substantially improve maximum aerobic capacity and aerobic recovery ability by improving the oxygen uptake and delivery, thus enhancing their rapid repeated sprinting ability.

Intensity Training

Seven men and four women (age 63 +/- 2 yr, mean +/- SD, range 61–67 yr) participated in a 12-mo endurance training program to determine the effects of low-intensity (LI) and high-intensity (HI) training on the blood lactate response to submaximal exercise in older individuals. Maximal oxygen uptake (VO2max), blood lactate, O2 uptake (VO2), heart rate (HR), ventilation (VE), and respiratory exchange ratio (R) during three submaximal exercise bouts (65–90% VO2max) were determined before training, after 6 mo of LI training, and after an additional 6 mo of HI training. VO2max (ml X kg-1 X min-1) was increased 12% after LI training (P less than 0.05), while HI training induced a further increase of 18% (P less than 0.01). Lactate, HR, VE, and R were significantly lower (P less than 0.05) at the same absolute work rates after LI training, while HI training induced further but smaller reductions in these parameters (P greater than 0.05). In general, at the same relative work rates (ie., % of VO2max) after training, lactate was lower or unchanged, HR and R were unchanged, and VO2 and VE were higher. These findings indicate that LI training in older individuals results in adaptations in the response to submaximal exercise that are similar to those observed in younger populations and that additional higher intensity training results in further but less-marked changes.
