RESUMO

Our purpose was to compare the acute effects of high-intensity interval training (HIT) vs. continuous moderate exercise (CME) on intraocular pressure (IOP) in healthy subjects. Fifteen young men (age=22.1±6 years) underwent 30 min of HIT (2 min of walking at 50% of reserve heart rate (HR) alternated with 1 min of running at 80% of reserve HR) and CME sessions (30 min of jogging/running at 60% of reserve HR) in random order (2-5 days between sessions). IOP was measured before (baseline), immediately after (post--exercise), 5 min after (Rec5) and 10 min after (Rec10) each exercise session. IOP was reduced post-exercise and remained reduced at Rec5 during both HIT and CME session, with no significant difference between interventions (~16% between 23%). However, IOP remained reduced at Rec10 only after HIT intervention (~19%), whereas IOP at Rec10 returned to levels similar to the observed at baseline during CME intervention. In summary, both HIT and CME equally reduced IOP immediately and 5 min after exercise session. However, only HIT was able to remain IOP reduced 10 min after exercise. These results suggest that HIT may be more effective than CME for reducing IOP in young healthy men.

RESUMO

BACKGROUND: The majority of anthropometric assessments in Turner syndrome (TS) patients has focused on height. AIM: To analyze body proportions in young adult TS patients either treated or not treated with rhGH, and to compare them with a group of age-matched healthy women. SUBJECTS AND METHODS: Standing height, sitting height, weight, foot and leg lengths, arm span, head circumference, biliac and biacromial diameters were measured in 52 non-treated TS patients, 30 treated with rhGH and 133 healthy women. RESULTS: Age at the start of rhGH therapy varied from 7.8 to 15.1 yr (10.0±1.3 yr), the duration of treatment from 2.8 to 8.2 yr (3.7±1.5 yr) and the mean recombinant human GH (rhGH) dose was 0.42 mg/kg/week (from 0.32 to 0.50 mg/kg/week). Nontreated patients did not show any difference in anthropometric variables when compared with the treated ones, except for hand length (p=0.02) and height (p=0.05), which were increased in the treated group. All anthropometric variables, except head circumference, were different when comparing TS patients (either treated or not) with age-matched healthy women. CONCLUSION: Brazilian TS patients either treated or not with rhGH showed almost no differences in terms of their body proportions. This result is probably due to the late age at the start of treatment, and/or the short period of rhGH administration. Hand length was different between the groups, showing the importance of including the extremities in body proportion assessment during rhGH treatment of TS patients.
