sprinting velocity ( v max ). 2 Recently, profiling and monitoring of running economy (RE) and v max has seen increased interest in mechanical stiffness. Mechanical stiffness is defined as an expression of a systems compressibility during the application of force, such as ground interactions in running

demonstrated an inverse linear relationship exists between load and velocity (load–velocity profile [LVP]), meaning that if maximal effort is given for the concentric phase of a lift, heavier loads cannot be lifted with the same velocity as lighter loads. 4 – 8 Furthermore, if maximal concentric effort is

The proposed testing battery is sensitive and can differentiate anthropometric and physical profiles within positional groups between youth

modeling alternative—to this and other “variable-centered” approaches—is to consider all motivational regulations simultaneously within a “person-centered” approach. Person-centered analyses enable researchers to identify homogenous groups (or profiles) of participants according to patterns that they

the era of expanded broadcast options. This research looks closely at the nature of two divergent groups of fans—those that consume primarily through broadcast platforms with little or no live experience, and those that primarily consume via live attendance. The profiling of these groups and analysis

-related motivation among secondary school students ( Barkoukis, Ntoumanis, & Thogersen-Ntoumani, 2010 ; Ntoumanis, Barkoukis, & Thogersen-Ntoumani, 2009 ). Therefore, investigation on the relationship between student PE motivational profiles and student PE experiences will be beneficial to our understanding of the

This study attempted to assess the construct validity of the performance profile technique (Butler, 1989) within elite track and field athletics. Twelve elite (senior international honors) athletes (5 male, 7 female: mean age = 21.2, SD = 1.81) completed their profile on five occasions across winter training and the indoor season. Support for the construct validity of the profile was identified by a reduction in profile areas of perceived need (F (4, 44) = 11.77, p < .05) which was congruent with the observed increase in performance (F (4, 44) = 26.30, p < .05) as athletes progressed from winter training to the peak of the competitive indoor season. Trend analyses also identified that areas of perceived need in profile constructs, which were classified as most important to performance, showed a greater and more rapid reduction across the five occasions compared to the least important constructs. However, the results raise some concern over the usefulness of the profile for detecting subtle but important changes in performance and perceived need.

-individual differences in student and athletic identity and the role that different identity profiles play in academic and sports outcomes. Therefore, the present study aimed to examine student-athletes’ identity in the upper secondary school context, where student-athletes are faced with academic and athletic
