Feasibility of a physical exercise intervention for patients on a palliative care unit: a critical analysis.

BACKGROUND: Recent exercise intervention studies have shown promising results in improving quality of life (QoL) and physical function (PF) in diverse chronic disease and advanced cancer patients. However, the effects of structured exercise in palliative care patients, having different therapeutic needs, lower life expectancies and PFs remain unknown. This study primarily aimed to assess the feasibility of an exercise intervention with follow-up by analysing recruitment numbers, screening procedures, acceptability, preferences, and safety of the exercise intervention as well as retention in follow-up. Our secondary aims related to changes in QoL and PF. METHODS: This study comprised of a one-arm design without a control group. Over 6 months, every in-hospital palliative care unit (PCU) patient was screened for eligibility. Eligible patients were asked to participate in a 2-week exercise intervention consisting of resistance training and/or endurance training with moderate or high intensity based on personal preferences and a 4-week follow-up. Before and after the exercise intervention, QoL and PF were assessed and a qualitative interview after the intervention addressed expectations and experiences of the exercise intervention. For follow-up, patients were provided with information on independent training and after 1 and 4 weeks a QoL assessment and qualitative interview were conducted. RESULTS: Of 124 patients screened, 10 completed the intervention with an adherence rate of (80 ± 25%), of which 6 patients completed follow-up. Endurance training was the most performed training type and only a few minor adverse events occurred in certain or likely connection to the exercise intervention. While physical QoL and PF measured by arm curl strength and time up and go performance improved, mental QoL and the other PF tests remained unchanged. CONCLUSION: Despite the challenges that were faced in our screening and testing process, that are specific to the palliative patient population with their unique therapeutic requirements and varying mental-/ physical capabilities, we discovered the 2-week exercise intervention to be feasible, safe, and well tolerated by palliative care patients. Moreover, it seems that short-term improvements in QoL and PF are possible. Further full scale studies are required to confirm our findings. TRIAL REGISTRATION: The study was retrospectively registered on 25.01.2022 in the German Clinical Trials Register (DRKS00027861).

Gaze Coordination of Groups in Dynamic Events - A Tool to Facilitate Analyses of Simultaneous Gazes Within a Team.

The performance and the success of a group working as a team on a common goal depends on the individuals' skills and the collective coordination of their abilities. On a perceptual level, individual gaze behavior is reasonably well investigated. However, the coordination of visual skills in a team has been investigated only in laboratory studies and the practical examination and knowledge transfer to field studies or the applicability in real-life situations have so far been neglected. This is mainly due to the fact that a methodological approach along with a suitable evaluation procedure to analyze the gaze coordination within a team in highly dynamic events outside the lab, is still missing. Thus, this study was conducted to develop a tool to investigate the coordinated gaze behavior within a team of three human beings acting with a common goal in a dynamic real-world scenario. This team was a (three-person) basketball referee team adjudicating a game. Using mobile eye-tracking devices and an indigenously designed software tool for the simultaneous analysis of the gaze data of three participants, allowed, for the first time, the simultaneous investigation of the coordinated gaze behavior of three people in a highly dynamic setting. Overall, the study provides a new and innovative method to investigate the coordinated gaze behavior of a three-person team in specific tasks. This method is also applicable to investigate research questions about teams in dynamic real-world scenarios and get a deeper look at interactions and behavior patterns of human beings in group settings (for example, in team sports).

Effects of basketball-specific high-intensity interval training on aerobic performance and physical capacities in youth female basketball players.

OBJECTIVE: The goal of this study was to investigate the effects of a 5-week, basketball-specific high-intensity interval training (HIIT) on aerobic performance in youth female basketball players. METHODS: Twenty-four athletes (age 15.1 ± 1.1 years; height: 170 ± 5.2 cm; body mass: 60.9 ± 6.0 kg) took part in the investigation. The training group (TG, n = 11) integrated 10 basketball-specific HIIT sessions in their normal team training, the other group (n = 13) continued their team training routine and served as controls (CG). All HIIT sessions contained different basketball-specific drills. Before (pre-) and after the training period (post-) physical fitness was tested. RESULTS: The Yo-yo intermittent recovery test (Yo-yo IR) performance was very likely increased in the TG (26,5 %). No improvements in the Yo-Yo IR performance were found in the CG (-6,8%). Likely positive effects in the TG were evident for the sprint and agility tests with (1.2 ± 2.4%, ES: 0.25, p = 0.29) and without ball (1.5 ± 4.6%, ES: 0.34, p = 0.20). The sprint and agility performance with ball significantly decreased in the CG by -2.8 ± 4.7% (ES: 0.49, p < 0.01). No differences between the groups were found for counter movement jump with arm swing (TG: ES = 0.14, p = 0.45, CG: ES = 0.20 p = 0.18), counter movement jump (TG: ES = 0.05, p = 0.70, CG: ES = 0.19, p = 0.10), squat jump (TG: ES = 0.06, p = 0.72, CG: ES = 0.10, p = 0.54) and long jump (TG: ES = 0.00, p = 0.82, CG: ES = 0.00, p = 0.81). CONCLUSION: A 5-week, basketball-specific HIIT improves the aerobic performance in young female basketball athletes.
