Data Tennis Study

Data columns
1-3 contain participant number, age, and group (0 = right handed, 1 = left handed).
Then, scores for the WAIS are reported under no pressure and prior to
performing the handgrip (WAIS_1-12_PRE), followed by the somatic (SomAnx_PRE)
and cognitive anxiety (CogAnx_PRE) scores in the WAIS under no pressure and
prior to performing the handgrip. Thereupon, accuracy scores for the serves
under no pressure prior to performing the handgrip (S1-8_Distance_Target_PRE)
and the mean distance of valid serves under no pressure and prior to performing
the handgrip (Mean_Distance_ValidServes_PRE) are listed. The lower the score,
the smaller the distance to the target. Serving errors are marked as missing
values with -1 or -2.

Afterwards scores
for the WAIS are reported under pressure after performing the handgrip
(WAIS_1-12_POST), followed by the somatic (SomAnx_POST) and cognitive anxiety
(CogAnx_POST) scores in the WAIS under pressure after performing the handgrip.
Thereupon, accuracy scores for the serves under pressure after performing the
handgrip (S1-8_Distance_Target_POST) and the mean distance of valid serves
under pressure after performing the handgrip (Mean_Distance_ValidServes_POST)
are listed. The lower the score, the smaller the distance to the target.
Serving errors are marked as missing values with -1 or -2.

数据列说明：
第1至3列依次为被试编号、年龄与组别（0代表右利手，1代表左利手）。
随后报告了握力测试前、无压力条件下的韦氏成人智力量表（WAIS）得分（WAIS_1-12_PRE），以及该测试情境下伴随的躯体焦虑（SomAnx_PRE）与认知焦虑（CogAnx_PRE）得分。继而列出握力测试前、无压力条件下的发球准确率得分（S1-8_Distance_Target_PRE），以及该情境下有效发球的平均距离得分（Mean_Distance_ValidServes_PRE）：得分越低，代表发球距目标的距离越近。发球错误以-1或-2作为缺失值标记。
