Background and Purpose: Although it has been assumed that higher physical activity (PA) levels will contribute to better physical fitness (PF) performance, the interplay between these two has yet to be investigated. Moreover, the majority of studies have been presented in children and adolescents, and older adults, while little is known about the correlation in the adult working population of physiotherapists. Therefore, the main purpose of the study was to examine associations between objectively measured PA and health‐related PF. Methods: We recruited 50 physiotherapists (72.6% women) from several public and private settings in the city of Zagreb. The SenseWearArmbandPro3 (SWA), a triaxial accelerometer placed on the nondominant hand for 7 consecutive days, was used to capture total energy expenditure (TEE) and active EE (AEE). Cardiorespiratory fitness included the Harvard step test, and muscular fitness was composed of sit‐ups in 60 sec and the Handgrip strength. Flexibility was evaluated using the Toe‐touch test. Results: TEE and AEE were moderately and positively correlated with the Harvard step test ( r = 0.65 and 0.62, p < 0.001), sit‐ups ( r = 0.70 and 0.59, p < 0.001), and the Handgrip strength test ( r = 0.74 and 0.64, p < 0.001). No significant correlation with the Toe‐touch test was observed ( r = −0.25 and −0.19, p > 0.05). When models were adjusted for age, weaker, but significant positive correlations remained. Discussion: The findings suggest that both cardiorespiratory and muscular fitness are positively associated with PA, whereas no statistically significant association with flexibility was detected. Thus, it is not surprising that we obtained moderate to almost strong correlations between TEE and AEE with cardiorespiratory and muscular fitness. Conclusions: In physiotherapists, TEE and AEE yield moderate correlations with health‐related PF, especially for cardiorespiratory and muscular fitness.

Background and Objectives: Headaches have become one of the global public health burdens in the 21st century. Although findings on the presence of headaches in general and older adult populations have been well-documented, little evidence has been observed for university students. Moreover, their level of quality of life seems to be impaired due to stressful events and the inability to cope with them. However, the mutual relations between headaches and quality of life in this population remain unknown. Therefore, the main purpose of the study was to examine the associations between lifetime headaches and the presence of headaches in the last 12 months with quality of life. Materials and Methods: In total, 1350 university students (age = 22.9 ± 2.3 years; 81.3% female) were recruited. Each participant was instructed to fulfill the Headache-Attributed Restriction, Disability, Social Handicap, and Impaired Participation (HARDSHIP) questionnaire, a reliable and valid tool to assess headache and quality-of-life characteristics. Headache characteristics, headache-related disability (HALT-90), and quality-of-life domains were analyzed using Spearman’s correlation analyses and structural equation modeling. Results: Participants with migraine reported more frequent and more intense headaches and substantially greater headache-related disability compared with those with tension-type or undifferentiated headache. The mean number of lost days in the previous 90 days (HALT-90) was 14.3 (SD 23.1) in the migraine group compared with 4.53 (SD 12.0) in the tension-type headache group and 5.77 (SD 10.9) in the undifferentiated headache group. Across most WHOQOL domains, students with migraine reported lower quality-of-life scores compared with other headache groups. The WHOQOL-8 total score averaged 30.9 (SD 4.79) in the migraine group and 33.6 (SD 3.93) among participants without headache. Greater headache burden was consistently associated with poorer quality of life, with headache-related disability showing the strongest correlation with energy for everyday life (r = −0.345, p < 0.001). Conclusions: These findings suggest that greater headache burden, particularly migraine and headache-related disability, is associated with poorer quality of life among university students. The results highlight the need for targeted prevention programs aimed at helping students manage stress more effectively and improve their quality of life.
