Digital devices have gained popularity in the last 10 years as a tool for exercise prescription, the monitoring of daily physical activity, and nutrition for the management of a health-related parameter. Therefore, the aim of this study was to assess the effectiveness of the use of digital devices to monitor exercise data in sedentary persons with HIV who exercise following an individualized activity pacing (AP) protocol on cardiorespiratory fitness body composition, blood lipid profile, and psychological parameters. Twenty-four PLWH were enrolled in an 18-week randomized, open-label, pilot AP exercise protocol. All participants were monitored by a Health Band connected to a mobile app that transmitted the data to a server. At week 3, they were randomized either in an experimental group (EG), in which an open device configuration enabled them to receive training data feedback (n = 12), or continued with no data feedback (control group, n = 12). The primary endpoint was improvement from the baseline of 15% of steady-state oxygen consumption ( V ˙ O2) during a 6-min walking test. Technical issues occurred when pairing the health band with the app, which prevented EG participants from regularly receiving data feedback, and with data transmission to the server, which enabled only 40% monitoring of the total training days. Consequently, the study outcomes could not be compared between the two groups, and participants also lost confidence in the study. However, 19 out of 24 participants completed the AP program. Overall, only 6 (32%) improved steady-state V ˙ O2, with no significant changes at W18 from the baseline. Significant reductions were observed of BMI (p = 0.040), hip circumference (p = 0.027), and total-(p = 0.049) and HDL-cholesterol (p = 0.045). The failure of digital device performance substantially affected study procedures, monitoring, and participants' engagement, and likely limited the potential benefits of the AP exercise program.

Teamgym is a new and emerging closed-skill sport, which includes tumbling, trampette, and floor programs performed by teams ranging from 6 to 12 athletes. The purpose of this study was to verify the concurrent validity of the session-rating of perceived exertion ([RPE] session-RPE) to quantifying the internal training load (ITL) of tumbling, trampette, and floor training sessions using Edwards' summated heart rate (HR)-zone method as a criterion measure. Session-RPE was obtained with 2 different instruments (i.e., CR-10 Borg's scale and visual analog scale) multiplied by the training duration (minutes). Ten female teamgym athletes (age = 21.7 [+ or -] 1.2 years; height = 164.9 [+ or -] 6.6 cm; and body mass = 54.6 [+ or -] 5.4 kg) participated in this study. High and significant correlations (r range: 0.77-0.85; [R.sup.2] range: 0.59-0.85; p < 0.01) were found between Edwards' HR and the session-RPE methods and between the 2 session-RPE instruments (r range: 0.92-0.97; [R.sup.2] range: 0.85-0.94; p < 0.01). The significant (p < 0.05) differences emerged between training sessions indicate that session-RPE discriminates ITL in relation to various technical skills. Hence, session-RPE can be a useful and inexpensive tool to quantify ITL in teamgym, and coaches could use this instrument to monitor their periodization plan as experienced by the athletes.

Purpose: To investigate whether monitoring of easily measurable stressors and symptoms can be used to distinguish early between acute fatigue (AF) and functional overreaching (FOR). Methods: The study included 30 subjects (11 female, 19 male; age 40.8 ± 10.8 y, VO2max 51.8 ± 6.3 mL ⋅kg-1 ⋅min-1) who participated in an 8-d cycling event over 1300 km with 18,500 climbing meters. Performance was measured before and after the event using a maximal incremental test. Subjects with decreased performance after the event were classified as FOR, others as AF. Mental and physical well-being, internal training load, resting heart rate, temperature, and mood were measured daily during the event. Differences between AF and FOR were analyzed using mixed-model ANOVAs. Logistic regression was used to determine the best predictors of FOR after 3 and 6 d of cycling. Results: Fifteen subjects were classified as FOR and 14 as AF (1 excluded). Although total group changes were observed during the event, no differences between AF and FOR were found for individual monitoring parameters. The combination of questionnaire-based changes in fatigue and readiness to train after 3 d cycling correctly predicted 78% of the subjects as AF or FOR (sensitivity = 79%, specificity = 77%). Conclusions: Monitoring changes in fatigue and readiness to train, using simple visual analog scales, can be used to identify subjects likely to become FOR after only 3 d of cycling. Hence, we encourage athlete support staff to monitor not only fatigue but also the subjective integrated mental and physical readiness to perform. [ABSTRACT FROM AUTHOR]

Developing a deep and contextualised understanding of risk is important for public health responses to young people's alcohol consumption, which is frequently positioned as an outcome of risky behaviour. This paper expands conceptualisations of risk to encompass its wider social and cultural context through a social practice exploration of young people's controlled and managed intoxicated alcohol consumption practice. We report data from a fourteen-month qualitative study of the alcohol consumption practices of 23 young people in England, drawing on group interviews and social media interactions. Our findings provide a nuanced understanding of risk-taking, demonstrating that risk is an important aspect of the ongoing participation and performance in alcohol consumption practice and that health information and advice can be and was frequently incorporated into drinking practice without contributing to fundamental change. This raises new questions about the effectiveness of health interventions that focus on the individual, discussed in the final section of the paper. [ABSTRACT FROM AUTHOR]

Purpose: This study aimed to assess 16-wk improvements of physical fitness, metabolic, and psychological parameters in people living with HIV (PLWH) exercising with the support of a smartphone application, as compared with a control group exercising without application. Methods: This was a randomized, open-label, pilot study enrolling PLWH in a 16-wk protocol consisting of moderate physical activity three times per week, which included an initial coach-supervised period of 4 wk, followed by 12 wk where participants trained independently. Participants were allocated to either an experimental group that trained using a smartphone application (APP) or a control group that practiced following a hard copy training program (No-APP). At baseline (BL) and after 16 wk (W16), patients were assessed for cardiorespiratory fitness, body composition, blood lipid profile, and POMS. Results: Forty-eight PLWH were screened and 38 were eligible: 20 were allocated to the APP group and 18 to the No-APP group. Two APP and two No-APP participants were lost to follow-up. Intention-to-treat analysis showed a W16 improvement from BL of ≥15% V˙ O2peak in 13 (72%) of 18 in APP, but only in 3 (19%) of 16 in No-APP participants (P = 0.025). Significant W16 improvements were observed in APP, but not in No-APP participants, in V˙O2peak; fat mass and fat-free mass percent; total cholesterol, LDL cholesterol, and triglycerides; vigor; and total mood by POMS. Accordingly, significant percent change differences between the APP and the No-APP groups were observed in V˙O2peak; fat and fat-free mass percent; total cholesterol, LDL cholesterol, and triglycerides; and depression, vigor, anger, and total mood by POMS. Conclusions: Exercising using a smartphone application improved cardiorespiratory fitness, body composition, cholesterol profiles, and psychological outcomes in PLWH. [ABSTRACT FROM AUTHOR]
