Plasma Nitrate

Background: Dietary supplements purported to increase circulating nitric oxide are very popular among consumers. We determined the acute impact of two novel dietary supplements on plasma nitrate/nitrite (NOx) and nitrite alone. Methods: 20 men and women (age: 24 ± 5 years) ingested two different nitrate-rich supplements (Resync Recovery Blend at 7.5 g and 15 g; Resync Collagen Blend at 21 g), or placebo, on four different days. Fasting blood samples were obtained before and 75 min following ingestion and analyzed for NOx and nitrite. Results: Nitrite was not differently impacted by treatment (p > 0.05). The NOx response for men and women was very similar, with no sex interactions noted (p > 0.05). Condition (p < 0.0001), time (p < 0.0001), and condition x time (p < 0.0001) effects were noted for NOx. Values increased from baseline to post-ingestion for the Resync Recovery Blend at 7.5 g (11 ± 9 to 101 ± 48 µM) and at 15 g (9 ± 5 to 176 ± 91 µM), as well as for the Resync Collagen Blend (9 ± 9 to 46 ± 21 µM), while values for placebo remained stable (9 ± 7 to 8 ± 5 µM). Conclusion: While nitrite alone was not impacted by treatment, both Resync products result in an increase in plasma NOx, with the increase proportionate to the quantity of “nitric oxide blend” ingredients contained within each product. Future studies are needed to determine the physiological implications of the increased NOx, as pertaining to exercise performance and recovery, in addition to other aspects of human health.

This research examined pro-environmental behaviour between adults and youths in Nginda ward, Embu north sub County. The research relied on two theories, theory of planned action and theory of pro-social behaviour. The research followed a descriptive design. Data were collected using questionnaires with closed and open-ended questions. The researcher administered questionnaires in person, and filled the entire questionnaire according to the participant’s responses. In total 245 participants comprising, 124 adults (comprising men and women), 121 form three students drawn from Muvandory, Rugumu and St. Alphose day Secondary Schools, and 58 standard seven pupils from Rugumu, Muvandory and ST. Francis primary schools were involved in the study. Descriptive statistics were used to summarise data and compare responses between groups. Differences in pro-environmental behaviour between adults and school children were examined to determine if the differences were statistically significant. A total of fourteen environmental problems were mentioned by participants to be prevalent in Nginda ward. The top three environmental problems mostly mentioned by participants included deforestation, water pollution and air pollution. The findings of this research can guide interventions by government and donor agencies seeking to mobilise and engage participation by both students and adults to combat environmental problems in Nginda ward. Future studies are needed to find out whether the scale will produce similar result in other group in this community which include business community, factory workers and eatery owners

Equipment Performance

Surfing has consistently been framed as a youth focused, male-dominated sport and culture. Despite surfing’s ageing demographic, neither the ways in which age impacts on surfing identities and mobilities, nor older surfer’s experiences and subjectivities, has been given scholarly attention. In this paper, I discuss research exploring the experiences and identities of middle-aged and older recreational male and female surfers in the south and south-west of England. The research illustrates that participation in surfing as a sport and lifestyle remains highly significant for some men and women through middle-age and into retirement. I consider the cultural barriers and challenges in dealing with a loss in physical performance through ageing, such as adaptations to their equipment, performance, and style, and the implications for how individuals negotiate bodily capital, space and identity. Nonetheless, older surfers also embrace different ways of being a surfer which challenge some of the more exclusionary aspects of surfing identities. Theoretically the paper develops an intersectional approach to sporting identity that explicitly recognises and accounts for the contribution of age to social identity. The research also contributes to the growing literature on physically active ‘post-youth’ leisure lifestyles, illustrating how shifting definitions of ageing have given ‘rise to new expectations, priorities and understandings’ of sporting lifestyles amongst those in middle age, and beyond.

The Impact

Attention has been given recently to herbal dietary supplements proposed to elevate testosterone and nitric oxide. This study evaluated the impact of a supplement containing Spilanthes acmella extract and Orchis latifolia extract on total blood testosterone, cortisol, and nitrate/nitrite in healthy men. Methods: Thirteen men (25.0±1.0 years) were randomly assigned (double-blind, cross-over design) to ingest a supplement (containing Spilanthes acmella extract and Orchis latifolia extract) and a placebo daily for 14 days, with a 14-day washout period between assignments. Fasting blood samples were collected on the mornings of days 1, 4, 8, and 15 and analyzed for testosterone, cortisol, and nitrate/nitrite. On day 15, subjects ingested an acute dose of the supplement or placebo and blood was collected every 30 minutes for three hours, and analyzed for testosterone. Results: No increase of significance was noted for any biochemical variable (p>0.05). However, a mean increase in testosterone from day 1 to day 15 of 29% was observed for the 13 subjects when ingesting the supplement, with a mean increase of 56% noted when only considering the 8 subjects who “responded” to treatment. Cortisol was increased approximately 19% when subjects ingested the supplement, compared to only 9% with the placebo. Conclusion: Two weeks of supplementation with an herbal preparation containing Spilanthes acmella extract and Orchis latifolia extract can increase testosterone in selected young men. The supplement also results in a moderate increase in cortisol. Larger scale studies are needed to further evaluate the impact of this herbal combination on testosterone in men.

Family Based Interventions

Depression affects over 17 million American adults yearly and has been identified as the leading cause of disability in people between the ages of 15 and 44 years. There is evidence that feeling neglect or a lack of parental attachment during childhood is associated with depression. One construct that has been overlooked is love from a parent. The purpose of this study was to analyze the association between individuals who felt not wanted/loved during adolescence and lifetime depression and to examine this association by gender. We examined 5114 participants aged 24–32 years at Wave IV of the National Longitudinal Study of Adolescent Health (Add Health) public use dataset. We used logistic regression analysis to determine the association between an individual feeling not wanted/loved by their parent/caregiver prior to age 18, covariates, and lifetime depression. We then stratified by gender and ran logistic models for both men and women separately. Overall, 16.2% ( n = 827) reported lifetime depression diagnosis, while 16.5% of the participants reported feeling not wanted/loved “often,” while 29.8% reported it as “sometimes.” Feeling not wanted/loved “often” was associated with higher odds of depression (AOR = 3.00; 95% CI, 2.45–3.66; p < .001) versus “sometimes” (AOR = 1.59; 95% CI, 1.31–1.90; p < .001). When stratified by gender, feeling not loved/wanted was associated with depression among both men (AOR = 3.70; 95% CI, 2.60–5.25; p < .001) and women (AOR = 2.73; 95% CI, 2.13–3.48; p < .001). Feeling not loved or wanted by a parent/caregiver during adolescence has serious implications, for both men and women. Future studies should further examine this construct and identify family-based interventions that focus on parent/caregiver and child relationships.

Two Measures

AbstractTo assess energy expenditure (EE) estimated by a metabolic system during the exergame Hollywood Workout on Xbox 360Kinect® and to compare this measure with the EE estimated by the exergame (EEEx). thirty-four physically active young males performed the Sports Athlete protocol of the Hollywood Workout. Oxygen uptake (V̇O2) and carbon dioxide production (V̇CO2) were measured before and during the protocol using a metabolic system. The absolute means V̇O2 and V̇CO2 were used to calculate the EE during the exergame session (EEMS). The EEEx (kcal) provided by the exergame was collected, and the two measures were compared. Mean V̇CO2 and V̇O2 during the Sports Athlete protocol were 1.8±0.4 L·min−1 (22.9±3.2 mL·kg−1.min−1) and 2.0±0.4 L·m−1 (25.4±2.6 mL·kg−1·min−1), respectively. The EEMS (300.3±53.4 kcal) was 88.6±34.7% greater than the EEEx (160.3±16.5 kcal; p<0.0001; d=3.7 [large effect size]). The EEMS was almost double EEEx. Thus, it is necessary to use caution when using EE information provided by an exergame interface. Further, future studies need to evaluate EE provided by other exergames. The companies that produce the games must be more attentive and adopt more precise methods in order to provide more accurate information to the users.

This study aims to understand the prevalence and characteristics of individuals aged 16 to 35 who are not in education, employment, or training (NEET) and the risk factors associated with being in NEET in China. The analysis uses the 2012 China Labor-Force Dynamics Survey to show that the NEET rate was 8 percent during the study period. Multilevel logistic regression indicates that women were more likely to be in NEET. Married women and female migrants had significantly higher risks of being in NEET, with migration having opposite effects for men and women. Education had protective effects against being in NEET, especially for women. Age had a nonlinear effect, with individuals aged 22 to 25 at the highest risk of being in NEET. I discuss implications for public policy and directions for future studies on NEET in China.
