# Responsiveness and Relationships of Shooting Performance to On-Ice Physical Performance Tests
## 3 Results
### Frequency of Goal Shot Success with Associated Puck Speed  
In total, 408 shots (3 SS and 3 WS by 34 participants) were fired on the empty goal before and after the IHCT. Of the 204 shots after the individual warm-up and before the IHCT, 69 over 102 (68%) SS and 66 over 102 (65%) WS were successfully placed. After executing the IHCT, the shot accuracy increased in both shot types (SS: 81/102 (79%), Figure 1; WS: 79/102 (78%), Figure 2). The shot accuracy was independent of athletes' playing position for either shot type and whether the shot was performed before or after the IHCT (\(\chi^{2}(2)<4.4\), \(p\) > 0.15).

Table 3: Maximum shooting speed of successful goal shots before and after the IHCT. Values presented as mean (one standard deviation, minimum and maximum).  
The percentage of athletes who made each slap shot successful increased by 26% after the IHCT. Interestingly, the subgroup (\(n=11\)) that shot with the highest speed on average before IHCT was associated with the top accuracy.  
Figure 2 clearly shows that the shot accuracy is positively affected by IHCT execution (class 3: +21%). Irrespective of shot type or accuracy class, the maximum puck speed markedly decreased after completion of the IHCT. The relative puck speed decrement (sum of all shots) over an overall shot success score (six shots before, six shots after the IHCT) is displayed for each athlete in Figure 3. The [PERSON]'s rank coefficient revealed  
Figure 1: Slap shot accuracy and associated puck speed on three attempts before (Pre) and after (Post) the IHCT: (**a**) Relative occurrence of successful goal shots; (**b**) Puck speed with the number of athletes within the respective subgroup. Values are mean with 90% confidence intervals.

no association (\(\rho\) = 0.15, \(p\) = 0.39, \(n\) = 34) between shot success and the IHCT-related puck speed decrement. However, this kind of shot success view is limited to those players who scored equally before and after the IHCT (\(n\) = 8). Moreover, the puck speed decrement assumes a similar shooting speed decline in both shot types.
