A phenomenological exploration of constraints for varsity football student-athletes with a sport-related concussion

ABSTRACT

Sports-related concussions are an emergent public health concern due to an increase in mortality and morbidity incident rates. The purpose of this study is to identify constraints in academic and athletic settings for varsity football student-athletes with a sport-related concussion. Twelve varsity football student-athletes from one institution who were diagnosed with a sport-related concussion took part in semi-structured interviews. This study used the social ecological model to identify intrapersonal, interpersonal, and environmental factors. Results suggested that varsity football student-athletes with a sport-related concussion experienced several constraining social ecological factors in the academic and athletic settings. Intrapersonal constraints related to loss of motivation, loss of social identification, stress, anxiety and depression, injury-specific issues, and internal pressure to return. Interpersonal constraints related to insufficient social support, lack of awareness and guidance on concussion knowledge, external pressure to return, and lack of academic support post-concussion. Environmental constraints related to return-to-play and return-to-learn protocols. Findings suggested that there remains a need to address constraining factors in the academic and athletic settings for varsity football student-athletes with a sport-related concussion.

Self-efficacy in college athletics: An exploratory study

ABSTRACT

This research examined the self-efficacy scores of National Collegiate Athletic Association (NCAA) college athletic trainers from Division I and Division III Southeastern universities. Implementing mental health best practices for college athletic trainers to recognize and to refer student-athletes with mental health issues and disorders have been top priorities of the NCAA and National Athletic Trainers’ Association (NATA). Purpose: This research explored the influence of the USA Mental Health First Aid (MHFA-USA) course of NCAA college athletic trainers’ self-efficacy levels of college student-athletes’ mental health referrals. Methods: A survey approach was adopted to measure participant (n=8) confidence levels of referring student-athletes to qualified mental health care practitioners utilizing a valid self-efficacy scale. Results: Overall, there was improvement in self-efficacy scores immediately following the course as well as consistent improvement at the one-month follow-up survey. Conclusions: There has been no current research on mental health formal trainings of practicing athletic trainers at the NCAA level. Findings from this study were promising as NCAA college athletic trainers’ self-efficacy improved following completion of the MHFA-USA course. Application in Sports: This study offers exploratory insight of the potential training of NCAA college athletic trainers to appropriately and to confidently refer student-athletes to appropriate care. Findings suggest mental health training programs focused on improvement of confidence levels of NCAA college athletic trainers should be considered.

The relationship between hip extensor strength and contralateral and ipsilateral hip flexor muscle length in healthy men and women

ABSTRACT

This study investigated the relationship between hip extensor (HE) strength to contralateral and ipsilateral hip flexor muscle length. Bilateral hip extension range of motion (ROM) was evaluated using the modified Thomas test using a hand-held goniometer in seventeen males (26 ± 7 yrs, 174.9 ± 6.72 cm, 79.4 ± 7.9 kg) and twenty-seven females (24 ± 2 yrs, 162.7 ± 6.40 cm, 67.2 ± 13.1 kg). Participants were classified as: a) restricted hip flexors (hip extension ROM > 6° from horizontal), b) neither restricted nor normal hip flexors (hip extension ROM between 0° to 6° from horizontal), and c) normal hip flexors (hip extension ROM < 0° from horizontal). Peak isometric HE force was obtained via a Biodex dynamometer where maximum voluntary contraction (MVC) was determined. Correlations were used to determine the relationship between flexor length to contralateral and ipsilateral HE relative strength. A One-way ANOVA was used to examine HE relative strength in relation to hip flexor length classified as restricted vs neither vs normal. There were no correlations between right hip flexor length and contralateral HE strength (r = -0.228, p = 0.137), right hip flexor length and ipsilateral HE strength (r = -0.241, p = 0.115), left hip flexor length and contralateral HE strength (r = -0.193, p = 0.210), and left hip flexor length and ipsilateral HE strength (r = -0.111, p = 0.472). The One-way ANOVA revealed no significant differences between the groups for the most restricted hip flexor and contralateral HE relative strength (p = 0.179) nor for the most restricted hip flexor and ipsilateral HE relative strength (p = 0.670). No significant relationships were found between HE strength and contralateral or ipsilateral hip flexor length. Although it is commonly suggested that practitioners address hip flexor length to assist with improving gluteal muscle strength, the results of this study do not validate this clinical practice. Despite the results indicating no correlations, practitioners are encouraged to address these impairments from both a functional and performance based perspective.

Emotional Intelligence as a predictor of success in personal training

ABSTRACT

Purpose: Little is known about the characteristics that contribute to success in personal training. It was hypothesized that emotional intelligence is a predictor of success. Because no instruments were available to address this hypothesis, instruments to measure emotional intelligence in personal trainers and success in personal trainers were developed for this study. Methods: A survey that included 95 items was completed by 225 certified personal trainers. Correlation and regression analyses were performed to determine which variables exhibited the most influence on success. Results: Emotional intelligence levels increased the variance accounted for by 48 percentage points over and above variables of weekly productivity, the type of facility the trainer is affiliated with, and years of employment, which accounted for less than 20% of total success (adjusted R squared = 0.665). Conclusions: Emotional intelligence levels appear to be an important contribution towards success as a personal trainer. Further research is recommended to inform the profession of personal training regarding what skills may contribute towards trainer success. Applications in Sport: As obesity levels remain a health concern, personal trainers will continue to be an asset towards assisting their clients in their pursuit of health and fitness goals.

Monitoring cardiac autonomic function and sleep duration in NCAA Division I football players during preseason and in-season using wearable tracking devices

ABSTRACT

Sleep duration (SD) is critical for exercise recovery, however collegiate student athletes are typically sleep deprived secondary to early morning workouts, class responsibilities, late day competitions, and travel. As such, cardiovascular autonomic function (CAF), measured via heart rate variability (HRV) and resting heart rate (RHR), can help monitor athlete recovery. PURPOSE: The purpose of this study was to compare two six-week periods, preseason and in-season, on HRV, RHR, and SD in college football players. METHODS: Eight malecollege football players were fitted with WHOOP® wearable activity/recovery tracking devices that use photoplethysmography and accelerometry to determine HRV (RMSSD), RHR (bpm), and SD (hrs/day). The devices were worn 24 hours a day over two six-weeks data collection periods during which the athletes participated in their normal day-to-day preseason conditioning and in-season practice sessions. RESULTS: A series of three, paired sample t-tests were performed to compare HRV, RHR, and SD between pooled data from preseason and in-season, reflecting the changes of the group and not the change of any individual participant. Both HRV (preseason =100 ± 35 ms, in-season = 82 ± 34 ms, p = 0.002) and SD (preseason = 4.55 ± 1.49 hrs/day, in-season = 5.33 ± 1.55 hrs/day, p = 0.002) were different between the two six-week periods while RHR was not different (preseason = 56 ± 6 bpm, in-season = 58 ± 6 bpm, p = 0.201). CONCLUSIONS: Athletes had higher HRV during the preseason period, indicative of greater parasympathetic activity, and had increased SD during the in-season period; however, RHR did not differ. APPLICATIONS IN SPORT: The examination of HRV, RHR, and SD during various periods of conditioning in collegiate football players found differences that could not be explained and therefore warrants further research.
