Employing the Interpersonal Process Recall technique, 7 Division I college tennis players reviewed and analyzed their performance, thoughts, and feelings as they watched video tapes of themselves competing in conference matches. Analysis of the audio transcripts indicated these women identified performance strengths, weaknesses, and intervening psychological factors.
Fifty 2- to 16- yr old pony stallions were randomly assigned to one of five treatments: Group 1, controls (no treatment); Group 2, 0.55 mg/kg stanozolol weekly for 13 treatments; Group 3, 1.1 mg/kg stanozolol every 3 wk for 5 treatments; Group 4, 1.1 mg/kg boldenone undecylenate every 3 wk for 5 treatments; and Group 5, 0.55 boldenone undecylenate weekly for 13 treatments. Mean plasma testosterone levels for Groups 2, 4, and 5 were elevated over controls (P<0.01) at 2, 8, and 9 wk, respectively. Testosterone levels for ponies in Group 3 did not differ from controls (P>0.05). There were no differences in mean plasma luteinizing hormone (LH) and follicle stimulating hormone (FSH) levels among groups (P>0.05). Daily spermatid production per gram of testicular parenchyma (DSP/gm) in Group 5 was lower than in controls (P<0.05), whereas DSP/gm was not different among groups 1 to 4 (P>0.05). There were no differences among groups (P>0.05) in the percentage of Stage 8 tubules or relative number of Leydig cells. The mean diameter of Leydig cells was less for Group 5 than for controls (P<0.05), but was not different for Groups 1 to 3 (P>0.05).
