Special Environments: Altitude and Heat.

High-level athletes are always looking at ways to maximize training adaptations for competition performance, and using altered environmental conditions to achieve this outcome has become increasingly popular by elite athletes. Furthermore, a series of potential nutrition and hydration interventions may also optimize the adaptation to altered environments. Altitude training was first used to prepare for competition at altitude, and it still is today; however, more often now, elite athletes embark on a series of altitude training camps to try to improve sea-level performance.

Energy Availability in Athletics: Health, Performance, and Physique.

The reported prevalence of low energy availability (LEA) in female and male track and field athletes is between 18% and 58% with the highest prevalence among athletes in endurance and jump events. In male athletes, LEA may result in reduced testosterone levels and libido along with impaired training capacity. In female track and field athletes, functional hypothalamic amenorrhea as consequence of LEA has been reported among 60% of elite middle- and long-distance athletes and 23% among elite sprinters.

The Signs and Significance of Personality Coherence in Personal Stories and Strivings.

The concept of personality coherence refers to the extent of psychological unity and wholeness embodied within each individual. In the present research, we examined the extent to which the narrative, functional, and organismic conceptualizations of personality coherence interrelate, as well as their associations with psychological abilities and personal adjustment. College students ( N = 391) narrated accounts of three personal memories; listed five personal strivings that they subsequently compared and evaluated; completed performance measures of their intelligence, wisdom, and creativity; and rated their hedonic and eudaimonic well-being.

Cardiovascular risk of adipokines: a review.

Over the last two decades, the understanding of adipose tissue has undergone radical change. The perception has evolved from an inert energy storage tissue to that of an active endocrine organ. Adipose tissue releases a cluster of active molecules named adipokines.

Associations of Breast Density With Demographic, Reproductive, and Lifestyle Factors in a Developing Southeast Asian Population.

The aim of this study was to investigate how breast density interacted with demographic, reproductive, and lifestyle features among Vietnamese women. Mammographic density and established risk factors for breast cancer were collected from 1651 women (345 cancer cases and 1306 normal cases) in Vietnam. The association of breast density categories with potential risk factors was investigated using Spearman's test for continuous variables and χ tests for categorical variables.

Teasing Apart Overclaiming, Overconfidence, and Socially Desirable Responding.

Contamination with positivity bias is a potential problem in virtually all areas of psychological assessment. To determine the impact of positivity bias, one common approach is to embed special indicators within one's assessment battery. Such tools range from social desirability scales to overconfidence measures to the so-called overclaiming technique.

Improving Prospective Memory in Persons With Parkinson Disease: A Randomized Controlled Trial.

Background: Prospective memory (PM) is essential for productive and independent living and necessary for compliance with prescribed health behaviors. Parkinson disease (PD) can cause PM deficits that are associated with activity limitations and reduced quality of life. Forming implementation intentions (IIs) is an encoding strategy that may improve PM in this population.

Feasibility of Presurgical Exercise in Men With Prostate Cancer Undergoing Prostatectomy.

Background: Prostatectomy is associated with short- and long-term morbidity, which includes attenuation of muscle function and deterioration of lean body mass. Physical function is a known predictor of morbidity and mortality, with initial evidence indicating that presurgical exercise is associated with fewer postsurgical complications and shorter hospitalization. The aim was to determine the feasibility of a supervised presurgical exercise program for prostate cancer (PCa) patients scheduled for prostatectomy.

Psychometric Validation of the Parental Bonding Instrument in a U.K. Population-Based Sample: Role of Gender and Association With Mental Health in Mid-Late Life.

The factorial structure of the Parental Bonding Instrument (PBI) has been frequently studied in diverse samples but no study has examined its psychometric properties from large, population-based samples. In particular, important questions have not been addressed such as the measurement invariance properties across parental and offspring gender. We evaluated the PBI based on responses from a large, representative population-based sample, using an exploratory structural equation modeling method appropriate for categorical data.

A Qualitative Study on Chinese Canadian Male Immigrants' Perspectives on Stopping Smoking: Implications for Tobacco Control in China.

China has the largest number of smokers in the world; more than half of adult men smoke. Chinese immigrants smoke at lower rates than the mainstream population and other immigrant groups do. This qualitative study was to explore the influence of denormalization in Canada on male Chinese immigrant smoking after migration.

A Qualitative Study on Unassisted Smoking Cessation Among Chinese Canadian Immigrants.

It is well-known that majority of smokers worldwide quit smoking without any assistance. This is even more evident among Chinese smokers. The aim of this qualitative study was to explore how Chinese Canadian immigrant men who smoked cigarettes perceived smoking cessation aids and services and how they used any form of the smoking cessation assistance to help them quit smoking.

A Surrogate Technique for Investigating Deterministic Dynamics in Discrete Human Movement.

Entropy is an effective tool for investigation of human movement variability. However, before applying entropy, it can be beneficial to employ analyses to confirm that observed data are not solely the result of stochastic processes. This can be achieved by contrasting observed data with that produced using surrogate methods.

Gendered Pathways From Child Abuse to Adult Crime Through Internalizing and Externalizing Behaviors in Childhood and Adolescence.

Gender differences in externalizing and internalizing pathways from child abuse to adult crime were examined across four waves of an extended longitudinal study ( N = 186 males and 170 females) using multiple-group structural equation modeling. Results show that child abuse was associated with both internalizing and externalizing behaviors in the elementary school years for both males and females. However, gender differences were found such that internalizing behaviors increased the risk of adult crime for females only, and externalizing behaviors increased the risk of adult crime for males only.
