Description: The study describes the differences in surface electromyography (EMG) activity of two forearm muscles in the lead and trail arm at specific phases of the golf swing using a 7-iron with three different grip sizes among amateur and professional golfers. Fifteen right-handed male golfers performed five golf swings using golf clubs with three different grip sizes. Surface EMG was used to measure muscle activity of the extensor carpi radialis brevis (ECRB) and flexor digitorum superficialis (FDS) on both forearms. There were no significant differences in forearm muscle activity when using the three golf grips within the group of 15 golfers (p > 0.05). When using the undersize grip, club head speed significantly increased (p = 0.044). During the backswing and downswing phases, amateurs produced significantly greater forearm muscle activity with all three grip sizes (p < 0.05). In conclusion, forearm muscle activity is not affected by grip sizes. However, club head speed increases when using undersize grips.

Description: In sport, choking under pressure is a negative athletic experience that may have psychologically damaging effects. The media recognizes that choking is a dramatic drop in performance, whereas researchers have labeled choking as any decrease in performance under pressure. This discrepancy between the media's and researchers' perception of choking leads to ambiguity among terms and confusion among researchers, applied practitioners, and the general public. Thus, the current position paper will: critically analyze current choking definitions and explore why they are not appropriate operational definitions; explain the current underperformance and choking terminology debate; offer an alternative choking definition that should be debated; and also identify ways that researchers can improve the robustness of choking investigations. It is hoped that this paper will stimulate debate and improve the quality of future choking research.
