Article Citation - Scopus: 1Investigation of Acute Effects of Slow Controlled Breathing on Fatigue and Vital Markers During Recovery Phase(AVES, 2023) Atli, E.; Uyanik, S.; Yildirim, A.; Yekteuşaklari, N.; Uzun, G.D.; Acar, M.; Akinci, B.Objective: Our study aims to examine the acute effects of slow controlled breathing on fatigue, heart rate, blood pressure, and respiratory rate during the recovery period after moderate-intensity aerobic exercise in young adults. Methods: Twenty-six volunteers between the ages of 18 and 30 were included in the study. Participants received the same aerobic exercise program. During the recovery period, the slow breathing group performed slow breathing with a respiratory frequency of 0.1 Hz (6 breath cycles/minute) combined with lower extremity static stretching exercises, while the control group only received a stretching exercise program. A modified Borg CR10 scale was used to evaluate perceived fatigue, a finger pulse oximeter was used for heart rate, and a digital sphygmomanometer was used for blood pressure. Participants were evaluated 5 times: at the beginning of the study, at the end of the aerobic exercise program (the 0th minute of recovery), 3rd minute of recovery, 6th minute of recovery, and 12th minute of recovery. Results: At the end of the study, no significant differences were found between the groups for any parameter at each time point (P > .050). There were statistically significant time-dependent differences within groups in terms of respiratory rate (slow breathing group P= .018, control group P > .001), fatigue (slow breathing group P ≤ .001, control group P < .001), and heart rate (slow breathing group P= .001, control group P= .017). There was no statistically significant time-dependent difference within groups for systolic or diastolic blood pressure (P > .050). Conclusion: The results of this study showed that slow controlled breathing combined with stretching or stretching alone applied in the recovery phase had similar acute effects on respiratory rate, heart rate, and fatigue but not on systolic and diastolic blood pressure. © 2023 AVES.

OBJECTIVE: To explore the effects of muscle fatigue on male handball players' shooting accuracy and ball speed. METHODS: Sixteen elite handball players (M-age = 17.1 +/- 1.7 years) participated in the laboratory and the field-testing sessions. Running speeds equal to 75% of participants' maximal oxygen uptake (VO2max) values from laboratory tests were used as the initial velocity for the 30-15 intermittent fitness test (30-15(IFT)) in the fatigue protocol. Participants shot to the target at random visual signals placed behind the target before and after fatigue. In order to measure wrist acceleration and ball speed, an accelerometer and a radar gun are used respectively and numbers of accurate and inaccurate shots also recorded. RESULTS: There were no significant differences between pre-fatigue and post-fatigue protocols in terms of accurate and inaccurate shots, and ball speed. Only wrist acceleration in the Y axis (M-pre(-fatigue) = 33.12, SD = 1.17msec; M-post - fatigue = 34.50, SD = 1.21msec) was affected by the fatigue protocol in inaccurate shots (p = 0.042). CONCLUSIONS: Muscular fatigue does not affect shooting accuracy and ball speed in male handball players.Article Citation - WoS: 6Citation - Scopus: 7Respiratory Muscle Endurance in Obesity Hypoventilation Syndrome(Daedalus Enterprises inc, 2022) Dusgun, Elif Sena; Aslan, Goksen Kuran; Abanoz, Ebru Seker; Kiyan, EsenBACKGROUND: An increase in respiratory work load and resistance to respiration cause a decrease in respiratory muscle endurance (RME) in patients with obesity hypoventilation syndrome (OHS). We aimed to evaluate and compare RME in subjects with OHS and a control group using an incremental load test and compare the RME of subjects with OHS in whom noninvasive ventilation (NIV) was and was not used. METHODS: Forty subjects with OHS (divided according to body mass index [BMI] as group I: 30-40 kg/m(2); and group II: 6 40 kg/m(2)) and 20 subjects with obesity (control group: 30-40 kg/m(2)) were included in the study. RME was evaluated using the incremental load test, and respiratory muscle strength (RMS) was evaluated using mouth pressure measurements. The 6-min walk test, Epworth Sleepiness Scale (ESS), Pittsburgh Sleep Quality Index (PSQI), Fatigue Severity Scale (FSS), EQ-5D Health-Related Quality of Life Questionnaire (EQ-5D), and the Obesity and Weight-Loss Quality of Life Instrument (OWLQOL) were performed. RESULTS: RME and RMS (%) in group I were lower than the control group (P=.001, P=.005, and P=.001, respectively). No significant difference was found between the 3 groups in terms of 6-min walk distance (6MWD) percentage predicted values (P=.98). RME in the NIV user group was higher than the non-user group (P 5.006). ESS, total PSQI, and FSS scores in the control group were less than group I (P=.01, P=.009, and P=.005, respectively) and group II (P 5.01, P <.001, and P <.001, respectively). The EQ-5D scores of the control group were higher than group II only (P=.005 and P=.005, respectively). There were no differences in OWLQOL between the groups (P=.053). CONCLUSIONS: RME was low in subjects with OHS but higher in those who used NIV. The incremental load test could be performed easily and safely in a clinic setting.
