Exercise Intensity and Activity Energy Expenditure of Professional Golf Players in Official Competitive Setting.

BACKGROUND: Research regarding the physical needs of professional golf players is lacking. With advances in wearable technology, it has become easier to analyze physiological responses such as heart rate (HR) to determine activity energy expenditure (AEE). The purpose of the study was to evaluate exercise intensity (EI) and AEE during 4 consecutive tournament's golf rounds using a popular wrist-based HR monitoring. HYPOTHESIS: Wearable systems for HR monitoring can be used to provide an accurate estimate of energy expenditure. STUDY DESIGN: Cross-sectional study. LEVEL OF EVIDENCE: Level 3. METHODS: A total of 20 male professional golfers participated in the study. Each player was monitored during an official tournament consisting of 4 rounds of 18 holes. EI and AEE were determined using HR wrist monitoring (Whoop Strap 2.0). We calculated the percentage of HRmax (%HRmax) and the percentage of HRres (%HRres) and the AEE in kcal/min using Keytel's formula. RESULTS: The calculated mean %HRmax and %HRres for the study population were 56.4% ± 1.8% and 40.5% ± 2.6%, respectively. Considering American College of Sports Medicine guidelines, these average percentages correspond to a moderate EI. The average caloric expenditure was 5.4 ± 0.4 kcal/min and 1555.8 ± 157.8 kcal per round considering an average golf round duration of 288.3 ± 19.5 minutes. CONCLUSION: A professional player's golf round is moderate physical activity. The AEE of this activity was equal to 5.4 cal/min, which is moderate energy consumption. CLINICAL RELEVANCE: These data could help golf coaches and conditioning coaches to have a better understanding of the load placed on golfers during tournaments.

Rodolfo Margaria and the First Walk on the Moon.

INTRODUCTION: During the Cold War years, the Space Race was largely supported by the efforts of many engineers and scientists, in particular human physiologists. Rodolfo Margaria (1901-1983), director of the Institute of Human Physiology at the University of Milan, was one of the most eminent and focused his studies on the mechanics of human locomotion in subgravity, in particular on the Moon's surface. Long before the real Moon landing, Margaria was able to correctly theorize how astronauts would walk on lunar soil, what would be the optimal pattern of progression, as well as determine the optimum and maximum speed at one-sixth of the Earth's gravity. On 21st July 1969 at 02:56 UTC, great excitement was aroused by the television images of Neil Armstrong's first steps on the Moon. Instead of walking, he moved around making small leaps, as expected from Margaria and colleagues.Grasso GS, Beretta EP, Miserocchi GA, Riva MA. Rodolfo Margaria and the first walk on the Moon.
