Using Performance Indicators to Evaluate Training Effectiveness: Lessons Learned

There is always a general interest in the evaluation of the effects of training on the overall goals of an organization. This paper describes an approach being taken in the nuclear power industry concerning the effectiveness of training on safety. Several approaches to the development of performance indicators as means for monitoring this effectiveness are described. We conclude that the structured use of the opinions of subject–matter experts is virtually the only way to permit success.     

Employment-related differences between male and female school psychologists

A total of 636 full-time school psychologist practitioners in Pennsylvania were surveyed and asked to complete a demographic data form and to estimate the actual percentage of time they spent in assessment, counseling, consultation, research, clerical tasks, and administrative tasks, and the amount of time they desired to spend in each of these roles. No statistically significant differences were found between male and female school psychologists in actual time spent in various roles or the time desired to be spent in various roles. Male school psychologists were found to work longer contract lengths and to make more money than their female counterparts. When monthly salaries were compared (adjusted for differences in contract length), statistically significant salary differences between male and female school psychologists were found.     

Intensity of exercise recovery, blood lactate disappearance, and subsequent swimming performance

The aim of this study was to examine the effects of active versus passive recovery on blood lactate disappearance and subsequent maximal performance in competitive swimmers. Fourteen male swimmers from the University of Virginia swim team (mean age 20.3 years, s= 4.1; stature 1.85 m, s= 2.2; body mass 81.1 kg, s= 5.6) completed a lactate profiling session during which the speed at the lactate threshold (V(LT)), the speed at 50% of the lactate threshold (V(LT.5)), and the speed at 150% of the lactate threshold (V(LT1.5)) were determined. Participants also completed four randomly assigned experimental sessions that consisted of a 200-yard maximal-effort swim followed by 10 min of recovery (passive, V(LT.5), V(LT), V(LT1.5)) and a subsequent 200-yard maximal effort swim. All active recovery sessions resulted in greater lactate disappearance than passive recovery (P < 0.0001 for all comparisons), with the greatest lactate disappearance associated with recovery at V(LT) (P= 0.006 and 0.007 vs. V(LT.5) and V(LT1.5) respectively) [blood lactate disappearance was 2.1 mmol l(-1) (s= 2.0), 6.0 mmol l(-1) (s=2.6), 8.5 mmol l(-1) (s= 1.8), and 6.1 mmol l(-1) (s= 2.5) for passive, V(LT.5), V(LT), and V(LT1.5) respectively]. Active recovery at VLT and V(LT1.5) resulted in faster performance on time trial 2 than passive recovery (P=0.005 and 0.03 respectively); however, only active recovery at V(LT) resulted in improved performance on time trial 2 (TT2) relative to time trial 1 (TT1) [TT2- TT1: passive +1.32 s (s= 0.64), V(LT.5) +1.01 s (s= 0.53), V(LT) -1.67 s (s= 0.26), V(LT1.5) -0.07 s (s = 0.51); P < 0.0001 for V(LT)). In conclusion, active recovery at the speed associated with the lactate threshold resulted in the greatest lactate disappearance and in improved subsequent performance in all 14 swimmers. Our results suggest that coaches should consider incorporating recovery at the speed at the lactate threshold during competition and perhaps during hard training sessions.
