The purpose of this study was to analyze the effect of gender and energetics on biomechanics and performance of masters swimmers over 1 season. Twenty-five masters swimmers (14 male and 11 female) were assessed 3 times (TP1, TP2, and TP3) during a season (male personal record in 200-m freestyle event: 173.00 ± 31.41 seconds: female personal record in 200-m freestyle event: 200.73 ± 25.02 seconds). An incremental 5 × 200-m step test was selected to evaluate velocity at 4 mmol·l⁻¹ of blood lactate concentration (v4), maximal blood lactate concentration after exercise (La(peak)), maximal oxygen uptake (V̇O2max), stroke frequency, stroke length (SL), stroke index (SI), and propelling efficiency of the arm stroke (η(p)). The 200-m freestyle performance and average swimming velocity (v200) were also monitored. Significant differences were observed between males and females for the 200-m freestyle performance, SL, SI, and La(peak). Performance (205.18 ± 24.47 seconds; 197.45 ± 20.97 seconds; 193.45 ± 18.12 seconds), SL (1.69 ± 0.17 m; 1.79 ± 0.13 m; 1.78 ± 0.15 m), SI (1.68 ± 0.31 m²·c⁻¹·s⁻¹; 1.83 ± 0.27 m²·c⁻¹·s⁻¹; 1.85 ± 0.27 m²·c⁻¹·s⁻¹), η(p) (0.32 ± 0.04; 0.33 ± 0.03; 0.33 ± 0.04), and V̇O2max (38.71 ± 3.44 ml·kg⁻¹·min⁻¹; 43.43 ± 3.71 ml·kg⁻¹·min⁻¹; 43.95 ± 7.02 ml·kg⁻¹·min⁻¹) have changed significantly throughout the season (TP1, TP2, and TP3, respectively) in female swimmers. In male, significant changes were found in η(p) (0.33 ± 0.07; 0.36 ± 0.05; 0.36 ± 0.06) and V̇O2max (41.65 ± 7.30 ml·kg⁻¹·min⁻¹; 45.19 ± 6.55 ml·kg⁻¹·min⁻¹; 50.19 ± 9.65 ml·kg⁻¹·min⁻¹) over the season (TP1, TP2, and TP3, respectively). Gender presented a significant effect on SL (TP2: η(p)² = 0.29; TP3: η(p)² = 0.37), SI (TP2: η(p)² = 0.25), and La(peak) (TP3: η(p)² = 0.42). v4 (TP1: η(p)² = 0.23), SL (TP1: η(p)² = 0.46), SI (TP1: η(p)² = 0.78; TP2: η(p)² = 0.37; TP3: η(p)² = 0.32), and η(p) (TP1: η(p)² = 0.28) had a significant effect on performance. Male masters swimmers have better performance, SL, SI, and La(peak) than female counterparts. Female masters swimmers enhanced significantly the 200-m freestyle performance over the season due to the improvement in swimming technique (SL, SI, and η(p)) and energetic factors (v4 and V̇O2max). Nonsignificant improvements were observed for the males' performance. Gender has a significant effect on SL, SI, and La(peak). Therefore, performance is more dependent on technical factors than energetics.

Aims and Objectives The purpose of this study was to explore the perceptions toward aging among Portuguese gay and bisexual men over 60 years old. Background Despite the growth of the older population, and the increased visibility and acceptance of lesbian, gay, and bisexual people in Western countries, the experience of aging in older gay and bisexual men is only beginning to be understood. Design We used a qualitative research methodology, based on critical gerontology, for establishing research questions and to identify the perspectives on the aging process in older gay and bisexual individuals. Methods We used a structured electronic inquiry with 25 gay and bisexual men over 60 years of age from Portugal. Data were analyzed using thematic analysis to help identify repeated patterns of meaning in the data set. Results The recurrent themes in the narratives of the aging experiences of the participants in the study were as follows: positive perceptions of aging, negative perceptions of aging, coping with being a gay/bisexual man and family ties, professional care, homophobia/discrimination, relationships and social support, intergenerational differences, mediating role of sexual orientation, sociopolitical changes, and personal characteristics. Conclusion Analysis of perceptions about the aging process in older gay and bisexual men emphasized the desire for normalization in the social awareness of sexual orientation. It is important to continue doing research on this topic and disseminate this information among professionals who work with older lesbian, gay, and bisexual people so that they may better understand how they can meet the specific needs of this population.

The main purpose of the present study was to verify the effects of a 12-week water aerobics program in a real-life context on health indicators and physical fitness in adults and older adults. Fifteen volunteers (58.80 ± 14.32 years old) were part of an experimental group (Exercise), and eight volunteers (59.00 ± 12.26 years old) were part of the control group (Control). The Exercise performed 45 min of water aerobics twice a week for 12 weeks; no physical exercise was permitted for the Control during the same period. The evaluations were performed the week before (pre-training) and after the training program (post-training). The primary outcomes were the strength and cardiorespiratory fitness variables and the secondary outcomes included body anthropometry, lipid profile and blood pressure. Adjusted analysis for age and baseline values showed no differences between Exercise and Control in post-training moment. However, there was a moderated tendency for increased explosive strength of the upper limbs (ηp2 = 0.17), reduced body fat (ηp2 = 0.17), reduced systolic blood pressure (ηp2 = 0.14) and triglycerides (ηp2 = 0.19) in Exercise. Within groups changes showed that the training program caused an increase mainly in explosive strength in the upper limbs (0.26 m, 95% CI, 0.03, 0.49; ES = 0.63) In addition, there was a significant decrease in fat mass (-0.89%, 95% CI, -1.74, -0.03; ES = 0.61) and in the systolic blood pressure (-0.83 mmHg, -1.46, -0.19; ES = 0.71). Nonetheless, no significant changes were observed for the lipid profile. These results suggest that 12 weeks of water aerobics performed twice a week in a real-life context seem to benefit the explosive strength, body composition, and blood pressure of adults and older adults but is insufficient to alter cardiorespiratory fitness and lipid profiles.

Objective. To translate the EuropeanGeneral Practice ResearchNetworkmultimorbidity definition according to Portuguese cultural and linguistic features. Methods. Similar to the process completed in several other European countries, a forward and backward translation of the English multimorbidity definition using the Delphi technique was performed in Portugal. Results. Twenty-three general practitioners (GPs)—14 males and 9 females—agreed to form the Portuguese expert panel for the Delphi process (59% acceptance rate).The Portuguese definition of multimorbidity was achieved after two Delphi rounds with a mean (SD) consensus score for final round of 8.43/9 (0.73). Conclusion. With this paper the definition of multimorbidity is now available in a new language—Portuguese. Its availability in the local language will raise Portuguese GPs’ awareness about multimorbidity and allow future national and international research. The operationalization of the definition will allow an easier identification of patients with multimorbidity.

Introdução: As disfunções sexuais constituem um problema de saúde de elevada prevalência, tornam-se necessários instrumentos de avaliação adaptados para a população portuguesa. Método: O objetivo deste estudo foi validar o Massachusetts General Hospital --- Sexual Functioning Questionnaire (MGH-SFQ) para a população portuguesa. Participaram 1.079 adultos portugueses que preencheram um questionário sociodemográfico e o MGH-SFQ. A idade dos participantes variou de 18 a 89 anos (M = 29,66; SD = 13,05), 32,6% (n = 352) foram homens e 67,4% (n = 727) mulheres. Resultados: O alfa de Cronbach obtido foi de 0,91 e as propriedades psicométricas da escala foram adequadas. A validação do constructo foi avaliada através da Análise Fatorial Confirmatória, configurou um modelo unidimensional adequado (RMSEA = 0,041, CFI = 0,974). Discussão: Tendo em conta os resultados da validação psicométrica, a dimensão da amostra e a aplicabilidade desse instrumento na prática clínica e sexológica, somos levados a afirmar que se trata de instrumento válido e confiável para avaliar o funcionamento sexual, quer de homens quer de mulheres portugueses.

There is a paucity of information regarding the needs of older Lesbian, Gay, and Bisexual (LGB) adults in Portugal; to help address this imbalance, this article describes a sample of Portuguese LGB older adults living in the large, urban center of Lisbon. Specifically, the article describes (a) the broad sociodemographic characteristics of LGB 60 years of age or older; (b) the type and level of social support and the nature of interpersonal relationships of these older LGB persons; (c) their physical and sexual health; and (d) the experiences and concerns when accessing social and health-care services, including disclosing their identity to social and health professionals. Across these areas, we further seek to evaluate any differences attributable to gender and compare our results to those in the literature, largely derived from North American studies.

This paper addresses the significant need for improvements in device version reporting and practice across the academic and technical activity monitoring literature, and it recommends assessments for new and updated consumer sensing devices. Reproducibility and data veracity are central to good scholarship, and particularly significant in clinical and health applications. Across the literature there is an absence of device version reporting and a failure to recognize that device validity is not maintained when firmware and software updates can, and do, change device performance and parameter estimation. In this paper, we propose the use of tractable methods to assess devices at their current version and provide an example empirical approach. Experimental results for heart rate and step count acquisitions during walking and everyday living activities from Garmin Vivosmart 3 (v4.10) wristband monitors are presented and analyzed, and the reliability issues of optically-acquired heart rates, especially during periods of activity, are demonstrated and discussed. In conclusion, the paper recommends the empirical assessment of new and updated activity monitors and improvements in device version reporting across the academic and technical literature.

This study aimed to compare emotional intelligence (EI) levels and Internet addiction (IA) by gender and age groups and to assess the predictive relationship between EI and IA. One thousand four hundred thirteen young people and adults participated in the study. Participants were between 17 and 81 years old (M = 38.70 years old, SD = 13.72 years old); 42.2% were male, whereas 57.5% were female. We used a sociodemographic questionnaire, the Schutte Emotional Intelligence Scale (Schutte, Malouff, & Bhullar, 2009), and the Internet Addiction Test (Young, 1998) as data collection instruments. Results showed that there is a weak, but statistically significant, negative relationship between EI and IA. We found higher levels of EI in older people and in women than in the youngest participants and in men. No relevant prevalence of IA was found in the participants of this study.

We explored perceptions of HIV-related stigma using a qualitative approach based on the findings of in-depth e-mail asynchronous interviews with 37 self-identified Portuguese men who have sex with men (MSM) with HIV infection and undetectable viral loads. Participants were asked to answer an online interview. Major findings concerned external perceptions of HIV-related stigma, HIV status disclosure, the impact of HIV on everyday life, the presence of double discrimination, and general perceptions of HIV-related stigma. Results revealed (a) stigmatizing and discriminatory behaviors and practices in psychosocial and inter-relational events, but not in accessing and receiving health care; (b) double exposure to stigma associated with being gay and having HIV; and (c) undetectability as an autonomous identity with important connections to social and interpersonal interactions. An important implication was related to multilevel risk perceptions and the psychosocial complexity and challenges of HIV infection. In Portugal, HIV is still a socially disabling disease.

Objective: This study aimed to investigate the foot contact time differences between obese and nonobese subjects during walking when crossing obstacles. Methods: Ninety-eight postmenopausal women were assigned to four groups, and their plantar pressure temporal data were collected using a two-step protocol during walking when crossing an obstacle set at 30% height of lower limb length of each subject. The initial, final, and duration of contact of 10 foot areas were measured. Results: Leading limb: (1) the heel groups initiated foot contact using the heel, and the non-heel groups initiated contact using the metatarsals; (2) heel obese subjects showed an earlier initial contact and a longer contact duration of metatarsals 2–3; (3) non-heel obese subjects showed an earlier midfoot initial contact. Regarding the trailing limb: (4) heel obese subjects showed an earlier midfoot initial contact and a longer contact duration of metatarsal 5; (5) non-heel obese subjects showed an earlier initial contact and a longer contact duration of metatarsals 4–5. Conclusions: (1) The non-heel groups’ foot rollover pattern may result from an attempt of rapidly restoring stability; (2) the heel obese subjects seem to regulate their plantar foot muscles to overcome their overweight; (3) the overweight of the non-heel obese subjects leads to a quicker backward foot roll-over from the metatarsals to the heel; (4) the overweight of the heel obese subjects can distort their footprints and/or their higher inertia may precipitate an anticipation of the midfoot contact, which can also explain the result observed for 5.
