Study aim: This cross-sectional study examined the relationship between biological factors, physical activity (PA), bone turnover markers (BTMs) and bone mineral density (BMD) in women with subclinical hypothyroidism (SCH) and healthy. Material and methods: The study included 135 women. Bone parameters were measured by the densitometry. Calcium, phosphorus, osteocalcin (OC), total alkaline phosphatase (ALP), bone-specific alkaline phosphatase (BALP), vitamin D and cross-linked carboxyterminal telopeptide of type I collagen (ICTP) were measured in blood serum. PA were evaluated by metabolic equivalent of task (MET). Results: Women with SCH had lower BMD in hip and lumbar spine, calcium, vitamin D and higher values of ICTP than the healthy group. In women with SCH, the affecting BMD in the femoral neck were ICTP (µg/l), (η² = 0.083), and also 25(OH)D (ng/ml), (η² = 0.080) and PA level (I/S), (η² = 0.115). BMD in the spine was affected by PA level (I/S), (η² = 0.173). The parameters affecting BMC in the femoral neck were 25(OH)D (ng/ml), (η² = 0.073). In all women sufficient levels of PA determined higher BMD. Conclusions: PA and BTMs significantly determine BMD levels. PA can be an important area of rehabilitation and physical therapy as an available measure to counteract BMD loss in postmenopausal healthy women and those with SCH.

Background During childhood and adolescence, skeletal microarchitecture and bone mineral density (BMD) undergo significant changes. Peak bone mass is built and its level significantly affects the condition of bones in later years of life. Understanding the modifiable factors that improve bone parameters at an early age is necessary to early prevent osteoporosis. To identify these modifiable factors we analysed the relationship between dairy product consumption, eating habits, sedentary behaviour, and level of physical activity with BMD in 115 young boys (14–17 years). Methods Bone parameters were measured by dual energy x-ray absorptiometry using paediatric specific software to compile the data. Dairy product consumption and eating habits were assessed by means of a dietary interview. Sedentary behaviour and physical activity was assessed in a face-to-face interview conducted using the International Physical Activity Questionnaire. Data collection on total physical activity level was performed by collecting information on the number of days and the duration of vigorous and moderate intensity (MVPA) and average daily time spent in sitting (SIT time). Results The strongest relationships with BMD in distal part of forearm were found for moderate plus vigorous activity, sit time, and intake of dairy products, intake of calcium, protein, vitamin D, phosphorus from diet. Relationships between BMD, bone mineral content (BMC) in the distal and proximal part of the forearm and PA, sit time and eating parameters were evaluated using the multiple forward stepwise regression. The presented model explained 48–67% (adjusted R2 = 0.48–0.67; p < 0.001) of the variance in bone parameters. The predictor of interactions of three variables: protein intake (g/person/day), vitamin D intake (µg/day) and phosphorus intake (mg/day) was significant for BMD dis (adjusted R2 = 0.59; p < 0.001). The predictor of interactions of two variables: SIT time (h/day) and dairy products (n/day) was significant for BMD prox (adjusted R2 = 0.48; p < 0.001). Furthermore, the predictor of interactions dairy products (n/day), protein intake (g/person/day) and phosphorus intake (mg/day) was significant for BMC prox and dis (adjusted R2 = 0.63–0.67; p < 0.001). Conclusions High physical activity and optimal eating habits especially adequate intake of important dietary components for bone health such as calcium, protein, vitamin D and phosphorus affect the mineralization of forearm bones.

Background/Objectives: The purpose of this study was to assess the body posture of kickboxing players. Methods: The study group included people training as kickboxers who actively participated in the training camp of the broad national junior team in the K1 and low-kick kickboxing leagues. The control group consisted of non-training people. The age of the study group ranged from 15 to 23 years. The ages of the control group participants varied from 14 to 20 years. A body posture test was performed by using the Moiré method, in accordance with the guidelines of the manufacturer of the Moiré 4G device. Results: The body posture test performed using the Moiré method showed statistically significant differences between the kickboxing training group and the control group. The parameters that showed statistically significant differences included the size of lordosis (KLL) and the depth of lordosis (GLL) in the lumbar spine. Higher values were observed in the kickboxing training group compared to the control group. There was no statistically significant difference between the kickboxing group and the control group in other parameters. Conclusions: The asymmetrical and flexed posture required during kickboxing training did not negatively influence the competitors’ spinal curvatures. Kickboxers had increased lumbar lordosis, which may be related to the specificity of the given discipline (stretching of the hamstrings and specific movements). This is a beneficial phenomenon that may reduce the risk of lower back pain. Kickboxing training did not affect the asymmetry of body posture in the sagittal plane.
