Lean body weight and aerobic and anaerobic factors have long been recognized as important determinants of performance in the 2000 met:E!r (M) 1 ace distance for rowing. Current research with noninvasive techniques has important implications for training and performance but is inconclusive. The purpose of this study was to investigate the relationship between a 2000 M rowing ergometer performance test (PT) and lean body weight (LBW), velocity at heart rate deflection (Vd), and anaerobic capacity (AC) in experienced rowers. Vd was used as an estimate of aerobic function. Thirteen trained male rowers (mean age 38.5 ± 8 years) were studied. Hydrostatic weighing at residual lung volume was used to estimate LBW. Each subject performed five exercise tests on a Concept II rowing ergometer: one 2000 M PT, two sub maximal step wise progressive tests to determine Vd (s/500 M), and two maximal 40-s anaerobic tests to determine AC. Intraclass correlation coefficients for the test/retest trials of Vd and AC were R = 0.740 and R = 0.863, respectively. Stepwise multiple linear regression analysis was used to explain variance in PT. The order of entry of each independent variable (and associated multiple R2 at each step) in the analysis was (1) Vd, 0.589; (2) LBW, 0.709; (3) AC, 0.720. The regression equation was PT (s) = 375.66 + 1.093 (Vd) - 0.820 (LBW) - 0.0007 (AC); S.E.E. = 10.01. It was concluded that performance in a 2000 M rowing ergometer PT is primarily dependent on aerobic metabolism and available lean body weight with anaerobic factors contributing to a lesser degree. These results have implications for specific training and team selection.

Prior research involving cycling, aggression, extraversion, and skill level is dated and limited. This study attempted to measure the levels of aggression and extraversion in each of the five categories of USCF riders to determine if personality differences existed between the different skill levels. Specifically, what proportion of extraverts versus introverts exist in each skill level and do personality characteristics and skill level effect the occurrence of aggression? Modified versions of the Aggression Inventory (AI) and the 55 Bipolar Rating Scale (55-BRS) were used to assess the subjects' tendencies to use aggression and personality characteristics. Results showed that no category has a particular concentration of either personality characteristic, indicating that the proportion of extraversion/introversion did not increase or decrease with increasing category levels. The results also showed a significant main effect for personality, where extraverts were significantly more likely to use verbal aggression and introverts were more likely to use avoidance techniques to avoid aggression. / School of Physical Education

The purpose of the study was to examine the effects of mental practice on the shooting accuracy performance of male water polo players at three skill levels. Thirty-six right handed athletes from the Quebec League, assigned by experienced coaches to novice, intermediate and elite groups according to their overall water polo playing ability, served as subjects. They were tested on shooting accuracy by the average score of ten shots in the beginning of the study, after a two-week mental practice treatment, and after a one-week break with no treatment. / A 3 way ANOVA with repeated measures on the last factor was conducted on the shooting accuracy scores. Those who received the mental practice program had significantly higher post-treatment scores than their control group counterparts who had received a relaxation training program during the treatment period. As noted above, the experimental group improved significantly from Pre to Post1 test-time, and there was no change in performance between the two Post-tests. There was no significant difference in shooting performance between Intermediate and Elite skill groups but both of them scored significantly better than the Novice group.

This study examined the relationship of amateur golfers' perceptions of their perceived physical self-efficacy to their performances on the golf course. Ninety-one amateur golfers completed two questionnaires and a participant profile. The perception of their physical ability in general was measured by the Physical Self-Efficacy Scale, and the Perceived Golf Ability Questionnaire was developed to assess their perceptions of golfing self-efficacy. Respondents were asked to play 15 consecutive golf games and record their scores on an especially designed detailed scorecard. The participants' data were divided into five levels of performance based on their handicap indexes. It was hypothesized that players having greater skills (low handicap indexes) would have higher general perceived physical self-efficacy, than those having lesser skills (high handicap indexes). It was also hypothesized that the more golf-specific self-efficacy measure would be a better predictor of performance on the golf course. ANOVA and hierarchical regression analyses were employed to determine the predictive values of the two measures of perceived physical self-efficacy of actual golf performance. The general physical self-efficacy measure did not predict performance whereas the more golf-specific measure was a significant predictor of performance on the golf course. The ability of specific items of the golf self-efficacy measure to predict performance of various shots in golf was also examined.
