While many benefit from testosterone supplementation therapy, others who do not meet the criteria for hormone supplementation have turned to dietary adjuncts as a way or gaining improvements in libido, energy, and physical performance. These oral adjunct medications include controlled substances such as androstenedione, androstenediol as well as other "over-the-counter" options like DHEA (dehydroepiandrosterone) and herbal remedies like Tribulus terrestris. This review will focus on the use of these adjunct medications in isolation, or in combination with testosterone supplementation therapy as well as the biochemical nature of the supplements, the results of scientific trials as well as the side effects that limit their use. At the end of this review, physicians will have an improved understanding of the popular testosterone adjuncts being used currently as well as the availability of these substances and ...

Psychological responses to acute resistance exercise in men and women who are obese. J Strength Cond Res 23 : [1548][1549][1550][1551][1552] 2009-The purpose of the study was to investigate the psychological response to the very first session of resistance exercise on positive well-being (PWB), psychological distress (PD), and perception of fatigue in untrained men and women who are obese. Forty-five (male = 22, female = 23) untrained, middle-aged volunteers (mean 6 SEM, 51.0 6 1.0; range, 40-69 years) participated in the study. Participants were divided into 4 groups according to sex and obesity level (i.e., men who are obese, men who are nonobese, women who are obese, women who are nonobese). The threshold for obesity was defined as waist circumference $94 cm for men and 80 cm for women. Measures included body composition, aerobic power, muscle strength, and quality of life (Short Form 36, SF-36). Before and after resistance exercise, participants completed the Subjective Exercise Experience Scale (SEES). Paired sample t-tests were used to assess changes in SEES scores within group pre-and post-exercise and repeatedmeasures analysis of variance were used to assess changes in SEES scores between groups. Exercise increased the perception of PWB in both women who are obese and nonobese, without changes in PD or fatigue. In women, the change in PWB after exercise was negatively correlated with most scales of the SF-36, particularly with the mental health dimension (r = 20.55, p , 0.01). No significant changes in PWB, PD, or fatigue were found in men who are obese. Acute resistance exercise improved PWB in women who are obese and nonobese and those with lower self-perceived quality of life scores at the start improved the most. In addition, resistance exercise did not increase feelings of distress in either women or men who are obese.

We found a significant effect of time, condition, Time × Condition, and Time × Group, but no group, Group × Condition, or Time × Group × Condition effects, such that the 5% above LT condition produced a worsening of affect in-task compared with all other conditions whereas, across conditions, participants experienced in-task increases in energy and tension, and in-task decreases in tiredness and calmness relative to baseline. Posttask, participants experienced mood improvement (decreased tension, anxiety, and increased calmness) across conditions, with a 30-min delay in the above LT condition. These results partially...
