Prior to presentation, two physically fit adults, a 39-year-old male and 40-year-old female, began supplementation with an over-the-counter thyroid preparation marketed as a metabolic accelerator and fat loss aid, tiratricol. Both participants took the supplement for 5 weeks (3000–4000 mcg/d) and 3 weeks (6000 mcg/d), respectively. At presentation, both complained of lethargy, loss of appetite, and muscle weakness. Upon initial laboratory evaluation, results revealed low thyroid stimulating hormone with profoundly elevated T3 values in both patients. After an extensive review of the literature, the cause of the problem was found to be the nutritional supplement they consumed contained tiratricol. After discontinuation of the supplement, thyroid levels slowly returned to baseline 40 days and 5 months later, respectively.

Students of all ages have documented a deficiency in health-related fitness knowledge (HRFK). However, improving students HRFK may require a change in teacher practices and professional development (PD).
This study, framed by Guskey’s Model of Teacher Change (GMTC; Guskey, 2002), sought to assist teachers’ HRFK instruction as part of their physical education curriculum and practices. Initially, researchers examined: (a) teachers’ perceptions of health-related fitness knowledge instruction, followed by, (b) selected teachers’ perceptions of the professional development (PD) methods and the approach to teaching HRFK.
Semistructured interviews were conducted among elementary physical education teachers’ (N = 9) in one suburban school district. A randomly selected smaller group of teachers (n = 5), had PD on Knowledge in Action Lesson Segments (KIALS), an approach to teaching HRFK. Teachers were asked to implement KIALS into their fifth grade physical education classes and interviewed two additional times.
Three themes emerged from the data: (a) HRFK is critical but I can’t get to it; (b) If you show it, they will implement it; and (c) Knowledge in Action gets the job done.
PD procedures in this study and KIALS were seen as favorable. Results paralleled GMTC principles, as researchers confirmed quality PD, and observations of positive student outcomes further reinforced teachers’ beliefs. Teachers also expressed a willingness to continue using KIALS after the completion of this study, concluding achievement of the final fourth principal of the change process. Findings suggested that KIALS, if presented with similar PD will be well-received by teachers supporting their efforts to improve student HRFK outcomes.

The purpose of this study was to determine students’ health-related fitness knowledge (HRFK) and physical activity levels after the implementation of a series of fitness lessons segments called Knowledge in Action (KIA). KIA aims to teach health-related fitness knowledge (HRFK) during short episodes of the physical education lesson. Teacher participants from one district (N = 10) were randomly assigned into either the intervention or comparison group. Intervention teachers used the KIA fitness lessons during fifth grade students’ physical education classes. These teachers received training sessions, teaching materials, and YouTube videos that modeled the KIA fitness lessons. Intervention fidelity was assessed through observations and a fidelity checklist. Students’ physical activity levels were measured using accelerometers and HRFK was examined by PE Metrics 28-question pencil and paper test. General linear models (GLM) and Hierarchical linear models (HLM) were used to examine group differences. Intervention students had a 3.4 (20%) greater unit improvement in HRFK scores when compared with their comparison counterparts (p < .001), at the school level. Student activity levels of moderate-vigorous physical activity (MVPA) time were similar in both groups (p = .64). Teachers can use the KIA fitness lesson segments or similar strategies to effectively teach HRFK in elementary physical education classes.

Despite having the desire to become physically active as a family, parents of children with visual impairments often lack the skills and resources needed to provide appropriate physical activities (PAs) for their children. The purpose of this study was to explore the intentions of parents of children with visual impairments toward including their children in PAs after participating in a PA program. In this descriptive qualitative study, the participants were 10 parents of children with visual impairments. A series of workshops were designed to provide parents with the skills and resources needed to promote PA for their family. Upon completion of the workshops, parents took part in one-on-one semistructured interviews that were subsequently transcribed and analyzed using a thematic line-by-line process. Two interdependent themes emerged from the data analyses: (a) eye-opening experiences and (b) transformed, more hopeful, and optimistic outlook. The results revealed that through the PA intervention, parents learned teaching strategies that were intended to increase their PA opportunities and garnered resources that allowed them to teach their children to participate in PA.
