Effects of Various Cognitive Video Stimulations on the Measured Stamina of Runners

Benoît R. Gonzales, Vincent Hagin, Peter W. Dowrick, and Alain Groslambert

This study assessed whether cognitive stimulations could improve running performance. Nine trained men (22.6 ± 2.1 years old) performed four tests of stamina i) a control test (CT) at 100% of maximal aerobic velocity without any specific attention instructions, ii) a video self modeling test filmed from behind (VB), where runners attended to a video-loop of themselves, iii) a video self modeling test filmed from the front (VF), and iv) a video of landscapes (VL) with music. The results revealed a significant increase (p = .004) of stamina in all video conditions: VB (235 ± 59 s); VF (229 ± 53 s); VL (242 ± 57 s), compared with CT (182 ± 33 s). The results showed that the oxygen consumption was significantly lower (p = .02) in VB. Two distinct processes could explain these results including the active role of mirror neurons and the influence of music.

Relationships Between Psychological Factors, RPE and Time Limit Estimated by Teleoanticipation

Jérémy B. J. Coquart, Yancy Dufour, Alain Groslambert, Régis Matran, and Murielle Garcin

The purpose was to study the relationships between psychological factors and perceptually-based values (Ratings of Perceived Exertion: RPE and Estimated Time Limit: ETL). The researchers obtained the scores of several psychological factors (anxiety, extraversion-introversion, neuroticism-stability, self-esteem, motivation, psychological resistance and endurance, desire for success, social desirability, dynamism, competitiveness, activity control, risk-taking, emotional control, aggressiveness, sociability, cooperation, acceptance of a judgment, and leadership) among 23 cyclists. The cyclists performed a graded exercise test in which the researchers collected RPE and ETL at 150, 200, 250 and 300W. Correlations between RPE/ETL and psychological factors were examined. RPE was correlated with leadership, psychological resistance and endurance. ETL was significantly correlated with psychological endurance. These results suggest a link between psychological factors, effort perception, and the time limits predicted by teleoanticipation. These relationships varied according to intensity.
