variety support in the context of “sampling” as defined within the Developmental Model of Sport Participation ( Côté et al., 2007 ). Within this model, Côté et al. ( 2007 ) highlighted that participating in a variety of sports (i.e., sampling) provides adolescents an opportunity to learn a breadth of

ChatGPT for Sample-Size Calculation in Sports Medicine and Exercise Sciences: A Cautionary Note
Jabeur Methnani, Imed Latiri, Ismail Dergaa, Karim Chamari, and Helmi Ben Saad
Therefore, these high rates of significant findings in light of the insufficiently powered studies raise concern on questionable research practices and publication bias in our field. 5 One approach to address this issue is to a priori estimate sample size. 6 Indeed, this was a major indication of a 2022
On Investigating Self-Talk: A Descriptive Experience Sampling Study of Inner Experience During Golf Performance
Yani L. Dickens, Judy Van Raalte, and Russell T. Hurlburt
-aloud methods presume that thinking translates easily and contemporaneously into words, typically focus on thoughts at the expense of other inner experiences such as emotions or sensations, lack random and representative sampling in favor of ongoing, continuous real-time reporting ( Hurlburt, 2011 ), and may be
Impact of Reduced Sampling Rate on Accelerometer-Based Physical Activity Monitoring and Machine Learning Activity Classification

and undesirable ( Small et al., 2019 ). In these cases, a reduction of sampling rate would offer the potential for longer continuous physical activity measurement, while reducing patient and caregiver interactions with the monitoring device. Currently, Brønd and Arvidsson ( 2016 ) offer the only side

Sample entropy quantifies the underlying regularity of human movements and has been used to study phenomena such as the effect
Minimum Sampling Frequency for Accurate and Reliable Tibial Acceleration Measurements During Rearfoot Strike Running in the Field
Kevin G. Aubol and Clare E. Milner
In field measurements of peak axial and resultant tibial acceleration during running are becoming increasingly common with the availability of wearable devices containing accelerometers. However, sampling frequencies vary between studies. Studies have used sampling frequencies between 100 and 2400

Based on the tripartite model and previous literature, the investigators expect relationships with peers and family members to significantly impact compulsive exercise scores in the sample. They also hypothesize that having greater body dissatisfaction and exercising more
Development of Perfectionism in Junior Athletes: A Three-Sample Study of Coach and Parental Pressure

Although current findings are suggestive of a link between coach pressure and athlete perfectionism, several issues remain
