Impact of Spotter Sex on One Repetition Maximum Bench Press Performance.

ABSTRACT: Nickerson, BS, Salinas, G, Garza, JM, Cho, S, and Snarr, RL. Impact of spotter sex on one repetition maximum bench press performance. J Strength Cond Res 35(9): 2397-2400, 2021-Resistance exercise is popular because of favorable health outcomes associated with increased muscular fitness. For these reasons, 1 repetition maximum (1RM), mean velocity (MV), and peak power (PP) are of interest during the bench press. However, research has yet to evaluate whether spotter sex impacts bench press performance. Therefore, the purpose of this study was to determine the impact of spotter sex on bench press performance during a 1RM testing protocol. Twenty resistance-trained individuals (10 men and 10 women) visited the laboratory on 2 separate occasions. Estimated 1RM was self-reported by subjects before the 1RM protocol. During their visits, subjects had their 1RM (kg), MV (m·s-1), and PP (W) determined on a bench press 1RM protocol while using a male or female spotter. Deception was used by telling subjects the intent of the study was to determine the reliability of a linear position transducer for measuring MV and PP during the 1RM trials. The main findings revealed that measured 1RM values for male weight lifters were significantly higher than estimated 1RM values when using both a male (p = 0.01) and female spotter (p < 0.01). In addition, results revealed MV and PP were significantly higher for the 1RM trials when male weight lifters had a male spotter (both p < 0.01). Alternatively, there were no significant differences in estimated vs. measured 1RM values for women as well as no effect of spotter sex on bench press strength (all p > 0.05). Practitioners should note that sex of a spotter does not seem to impact measured 1RM. However, notable influences may be observed within MV and PP.

The Relationship between Perceived Coaching Behaviors, Competitive Trait Anxiety, and Athlete Burnout: A Cross-Sectional Study.

Athletes possibly experience a great deal of stress which may cause anxiety and burnout. Athletes' perceptions of their coaches' behaviors influence their performance and psychological well-being. The purpose of this study is to investigate the relationship between athletes' perception of their coaches' coaching behaviors and burnout, and also to examine the medication effects of competitive trait anxiety on the relationship. A total of 368 collegiate athletes participated in the study, and their ages ranged from 20 to 26 years old (Mage = 21.21 years, SD = 1.07 years). A cross-sectional research design was employed to collect the data. Descriptive statistics and structural equation modeling are utilized to analyze the data. Trait anxiety in athletes had a significant correlation with athlete burnout as well as significant pathways. Controlling coaching behaviors were significantly related to athletes' competitive trait anxiety, whereas autonomy-supportive coaching behaviors were not significantly related to trait anxiety. A significant positive pathway from controlling coaching to trait anxiety was observed. The bootstrapping results indicated a significant and indirect pathway from controlling coaching to athlete burnout via competitive trait anxiety. Given that controlling coaching behaviors affected trait anxiety and, in turn, burnout, it is concluded that coaches should provide less controlling coaching to reduce anxiety and burnout in athletes.

Validation and Reliability of the Korean Version of the Sport Anxiety Scale-2.

The main purpose of the present study was to examine the validation and reliability of the Korean version of the Sport Anxiety Scale (SAS-2Kr) by evaluating its factorial invariance across gender. A total of 303 Korean collegiate athletes (198 males and 105 females) from 9 sports participated in the study, and they completed the demographic questionnaire and the SAS-2Kr containing 15 items to measure multidimensional trait anxiety and individual differences in the cognitive and somatic anxiety experienced by athletes. The results of this study indicated that the construct validity in the SAS-2Kr was well established in that the values of the standardized factor loadings, composite reliability, and average variance extracted values were above the recommended cutoff points. The multiple-sample confirmatory factor analyses showed the SAS-2Kr could be generalizable across gender in college samples. The results also indicated that the SAS-2Kr supported the original 3-factor model of SAS-2 in English consisting of somatic anxiety, worry, and concentration disruption, and thus this study provides useful information for researchers to understand the athletes' tendency to experience anxiety reactions in sport situations. Suggestions for future research on competitive trait anxiety are provided in the discussion section.
