Comparing Cardiovascular and Metabolic Demands between Two Bouts of High-Intensity Functional Training (HIFT)

Abstract

Purpose: The overall objective of this study is to determine if the wide variety of exercise selections in High-Intensity Functional Training (HIFT) affects the metabolic demands between each workout. Methods: A crossover design with six experienced participants were used to compare the mean and maximum values of heart rate, oxygen consumption, the difference between post-exercise and resting blood lactate accumulation, immediate post-exercise rating of perceived exertion, and total caloric expenditure from exercise and 15-minute post-exercise oxygen consumption between a seven-minute workout of burpees and an eight-minute workout box jumps and ascending weight and repetitions of the barbell deadlift. An independent T-test was used to compare the outcome variables between the two workouts. Results: Mean and maximal oxygen consumption was significantly greater in the seven minutes of maximum burpees compared to the eight minutes of box jumps and deadlifts. There was no significant difference in mean and maximal heart rate, blood lactate accumulation, rating of perceived exertion, and total caloric expenditure between the two workouts. Conclusion: Both bouts of HIFT were executed to complete as many repetitions as possible, which lead to similar cardiovascular and metabolic measures except for the participants’ oxygen consumption. This difference was primarily due to the ascending weights and the repetitions of the deadlift. All participants’ average repetitions completed per minute decreased significantly when they came across the 275-pound barbell for 25 repetitions. Applications in Sport: These findings show that even though all HIFT workouts are performed at high intensity, the variance in exercise selection can impact the participant and how they respond to each workout requires further research into how these different modalities and variations can impact exercise participants and their limitations to better understand HIFT and how it can compare to other forms of exercise.

Associations between game outcome, game location, and wellness in Division I women’s lacrosse athletes

Abstract

PURPOSE: Athlete wellness—a subjective measure assessing the response to the previous day’s physiological and psychological stress—has subsequent influence on the day’s performance. Game location (i.e., home, away) is also believed to influence performance and game outcome. The purpose of this study was to determine if game location and game day wellness were related to game outcome for a collegiate women’s lacrosse team. METHODS: Athletes (n = 34) completed a daily subjective wellness survey each morning. The survey consisted of questions related to muscle soreness, sleep quality, stress, and fatigue, with responses rated in arbitrary units (AU) using the anchors of 0, 25, 50, 75, and 100, and higher scores represented positive affect. The scores of each of the four responses were averaged to calculate the overall wellness score. Individual athlete wellness scores were categorized as above or below the team mean for each game. A chi-square analysis was used to evaluate the relationship between the wellness variables and game location with the game outcome. RESULTS: The season consisted of seven losses and nine wins, with 10 games played at an away location and six games played at home. Location was not related to game outcome (p = .152), nor were any of the game day wellness sub-scores or composite score (wellness: 71.4 ± 2.7 AU, p = .614; muscle soreness: 63.8 ± 2.9 AU, p = .527; sleep: 83.0 ± 3.4 AU, p = .527; energy: 80.0 ± 1.5 AU, p = .490; stress: 65.0 ± 4.7 AU, p = .490). CONCLUSIONS: Game location, and game day wellness were not related to game outcome in Division I women’s lacrosse athletes. These findings refute previous beliefs regarding the importance of “home field advantage.” Further exploration regarding sleep quality differences in relation to game location and subsequent game outcome are warranted. APPLICATION IN SPORT: Coaches and athletes can use this information to refute previously believed notions about advantages to playing home games. Coaches can work with their athletes to ensure similar pre-game preparation on and off the field for optimal performance.

Effect of Shoulder and Hand Position on Sport-Specific Grip Force in Rock Climbers

Abstract

Purpose: Rock climbing has become popular as a recreational activity. Overuse injuries of fingers and hands are common due to uniquely high demands placed on these structures. Climbers adapt hand positions to match types of holds on rock climbing routes, with open-hand and half-crimp positions being most used. The primary purpose of this study was to explore differences in climbing-specific grip strength between 2 hand positions and 2 shoulder positions. Methods: Participants’ maximum isometric pull was tested on a 20mm edge climbing hold attached to a force transducer in each of 4 hand/shoulder position combinations bilaterally. 46 participants (20 female) across skill levels were included for analysis. Peak force was extracted and normalized to participants’ body weight. Mixed model ANOVAs were used to explore effects and interactions between shoulder position, hand position and skill level. Paired t-tests were used explore asymmetry between dominant and non-dominant hands. Results: Half-crimp position was stronger than open-hand position and shoulder position did not impact force production. Climbers of higher skill level had higher force production in both hand positions. Greater asymmetry was observed in climbers of higher skill in the half-crimp position only.

Conclusion: Findings support using a single shoulder position for testing finger strength versus multiple positions. Climbers of all levels should emphasize both open-hand and half-crimp training for performance and injury prevention. Applications in Sport: Shoulder position did not impact force in open-hand or half-crimp grip. Higher skill climbers produced greater force. Force was higher in half-crimp versus open-hand positions independent of skill. Climbers use open-hand and half-crimp positions and should train both for performance and injury prevention. Strength testing could include a single shoulder angle for efficiency.

Affective Forecasting and Social Physique Anxiety among Female Athletes: A Pilot Study

ABSTRACT

While people make affective forecasts every day, they overestimate the impact of future events on their emotional states — displaying an impact bias. Comparatively few studies examined athletes’ accuracy of specific emotions in aesthetic sports. To remedy this gap, we explored predicted social physique anxiety and self-presentational concerns in an experimental analysis of 156 female collegiate volleyball players between 18 and 23 years of age. Athletes completed a Demographic Questionnaire and the Trait Anxiety Inventory before being randomly assigned to one of the four experimental conditions (i.e., control, practice, intersquad scrimmage game, or heavy spectator game). After the manipulation, their social physique anxiety levels and self-presentational concerns in sport were assessed. A one-way Analysis of Variance revealed significant differences among the conditions on social physique anxiety, F(3, 152) = 4.70, p = .004, h² = .09. Specifically, Tukey HSD post-hoc test revealed that athletes in the control condition scored higher on social physique anxiety (M = 2.74, SD = 0.71) compared with intersquad scrimmage game condition (M = 2.15, SD = 0.70), p < .01, d = .83. No other significant differences were observed. Contrary to prior literature, athletes overestimated their forecasted anxiety in the control group and underestimated their forecasted social physique anxiety levels in a game closed to large crowds. Our study extends previous work on affective forecasting, and more importantly, provides additional information on specific emotions in aesthetic sports. Our findings suggest that coaches and sport psychology consultants could potentially reduce athletes’ social physique anxiety and self-presentational concerns by channeling their attention to the task at hand.

Understanding written message framing, motivation, and performance in competitive cyclists

Abstract

Purpose: An athlete’s motivation and sport performance is impacted by their environment, including the interpersonal relationship between athlete and coach. What messages the coach conveys, and how those messages are received, can impact performance. Conveying messages via controlling message framing (dictating goals and outcomes) or informational/supportive message framing (providing information and recognizing effort) may impact the athlete’s perceptions of the environment and alter motivation, thus impacting performance. Endurance sports, such as cycling, require high amounts of self-determined motivation due to the duration and solo nature of training. Often the primary interaction with the coach is through online written communication. As such, the goal of this study was to explore the impact of written forms of controlling and informational/supportive message framing on motivation and performance in trained cyclists. Methods: Using a crossover design, 11 amateur competitive cyclists (9 Male, 2 Female; age 43.6 ± 10.3 years) were randomly assigned a written training protocol containing either controlling or informational/supportive messages and describing a specific workout with a goal of participation to exhaustion. Perceived competence, perceived autonomy, motivation, and performance (time to exhaustion) were measured for each trial. Results: No significant differences were found in perceived competence, perceived autonomy, motivation, or performance between controlling or informational/supportive conditions. There was a significant correlation between pre-task competence valuation and post-task perceived competence (r = -0.738), and autonomous motivation and time-to-exhaustion (r = -0.674) in the controlling condition. Additionally, a significant correlation was seen between perceived competence and perceived autonomy (r = 0.666) in the informational/supportive condition. Conclusions: A relationship does exist between written message framing and motivation. Motivation and performance may be increased by using informational/supportive messages in written communication with athletes. Application in Sport: Coaches must be aware of the impact communication has on athletes even when using online platforms. These interactions should be considered an important part of the coach-athlete relationship. For optimal athlete motivation and performance, coaches should focus on creating well-designed workouts that include detailed written information using supportive wording.
