dc.description.abstractThe aim of the study was to investigate the effects unknown loading would have on the second pull from blocks in comparison to known loading. Ten male participants (stature 176.85 ± 8.05cm; mass 84.43 ± 30.7kg) from Cardiff Metropolitan University took part in the study, which involved performing 8 repetitions of the second pull from blocks, 4 known and then 4 unknown. The participants 1 – repetition maximum (1RM) was found, the loads at 60%, 70%, 80% and 90% (mean 1RM 162.5 ± 30.7) being used for the testing protocol. A TENDO linear transducer was used to collect data on Peak Power Output (PPO) and Peak Velocity (PV). Analysis was conducted via One – Way Repeated Measures ANOVA to compare the effects of known and unknown loading on each of the intensities tested. Statistical analysis revealed no significant difference (p > 0.05) between intensities for PPO regardless of whether conditions were known or unknown. However, there were significant differences (p > 0.05) in PV between all loads apart from between 70% and 80% when loads were known, with significant differences (p > 0.05) between all intensities when loads were unknown. Despite no significant differences between loads, the highest mean value for PPO was found at 80% 1RM for both known (1382.7 ± 194.6 W) and unknown (1357.3 ± 205.8 W). The highest mean values were found at 60% for both known (1.402 ± 0.256 m/s) and unknown conditions for PV (1.375 ± 0.237 m/s). From these results it can be suggested that using unknown conditions has no effect on PPO or PV values, with known conditions proving more effective at reaching peak mean values for both variables. However, it does give strength and conditioning coaches and athletes an indication as to which intensity is best suited if improvements in PPO or PV are the main focus when using the second pull from blocks.en_US
