Background: Physical exercise cannot be separated with body sweating, which is one of effort the body to maintain the homeostatic and thermoregulation. the factor of sweat rate is environment condition, for examples are room temperature and relative humidity. Aim: Compare physical exercise in two different environmental conditions, including at night and in the morning to the sweat rate. Method: The quantitative research design with descriptive design uses a one shot case study. Using as many as 40 male students divided into four groups. Result: To find out the differences between the two groups, this study used independent samples t-test. The group continuous running activity in the morning and at night has an average sweat rate as much as 0,49 liter ± 0,28 and 0,62 liter ± 0,31 with the value of (p > 0,05). The group cycing with HIIT activity in the morning and at night has an average sweat rate as much as 0,34 liter ± 0,177 and 0.42 liter ± 0,176 with the value of (p > 0,05). Conclusion: The average sweat rate of night physical exercise is more than the average sweat rate in the morning, even though there is no significant difference between both.Keywords: Relative humidity, night physical exercise, morning physical exercise, sweat rate, thermoregulation

The purpose of this study was to show a comparison of recovery sport massage methods and cold water hydrotherapy to the physiological recovery of decreased lactic acid levels and pulses using a purposive sampling technique. This research method is quantitative research with a descriptive approach. The subjects of this study were 16 Wushu Sanda KONI athletes in Blitar District which were divided into two groups. For data analysis using the mean, standard deviation and pair t test and unpair t test. Based on the results of this study indicate that there are significant differences for the comparison of the decrease in lactic acid levels between the use of recovery sport massage methods and cold water hydrotherapy, with calculations that show a value of P <0.05 where the average value of lactic acid levels decreases recovery sport massage 4.92 nMol / L and cold water hydrotherapy of 3.91 nMol / L. Whereas the decrease in pulse ratio showed that there was no significant difference between the use of recovery sport massage and cold water hydrotherapy methods, with calculations that showed P> 0.05 where the average pulse rate recovery sport massage method was 8.35 Beat Per Minute and hydrotherapy cold water 77.5 Beat Per Minute

Pada dasarnya manusia melalui dua fase di dalam hidupnya yaitu fase ergotropic yang mana manusia beraktivitas pada pagi hari dan fase trophotropic yaitu manusia melakukan recovery di malam hari. Penelitian ini bertujuan untuk membandingan dua jenis olahraga yang dilakukan pada pagi dan di malam hari terhadap kualitas tidur. Metode penelitian yang digunakan adalah kuantitatif dan pendekatan deskriptif dengan perlakuan one shot case study design yang menggunakan 40 mahasiswa putra sebagai subjek penelitian yang terbagi dalam empat kelompok. Untuk mengetahui perbedaan kualitas tidur pada sesi pagi dan malam hari menggunakan uji independent samples t test. Berdasarkan hasil penelitian ini menunjukkan bahwa kualitas tidur pada kelompok yang yang melakukan aktivitas continuous cycling berintensitas sedang  di sesi pagi dan malam hari memiliki nilai P > 0,05 dan kualitas tidur pada kelompok yang melakukan aktivitas cycling with High Intensity Interval Training (HIIT) di sesi pagi dan malam hari memiliki nilai P < 0,05. Kesimpulan dari penelitian ini adalah tidak terdapat perbedaan yang signifikan pada kualitas tidur antara kelompok yang melakukan aktivitas continuous cycling berintesitas sedang di pagi dan malam hari namun terdapat perbedaan yang signifikan pada kualitas tidur antara kelompok yang melakukan aktivitas cycling with HIIT di pagi dan malam hari.
