Perbandingan efek kerja joging selama 30 menits terhadap penurunan cairan tubuh studi eksperimen pada kelompok Indeks Masa Tubuh (IMT) Overeight dan normal
Penelitian ini bertujuan untuk mengetahui penurunan cairan tubuh pada siswa kategori Overweight dan kategori siswa Normal SMA 23 Kabupaten Tangerang dengan aktivitas joging selama 30 menit. Penelitian ini dilaksanakan selama 2 hari, pada tanggal 16 juli dan tanggal 17 juli. Metode yang digunakan eksperimen two-groups “pre-test and post-test design´. Teknik Pengambilan sampel pada penelitian ini menggunakan Purposive Sampling. Jumlah populasi laki-laki kelas 2 sebanyak 65. Sampel diambil sebanyak 20 orang karena sampel sudah memasuki kriteria yang sudah ditentukan oleh peneliti. Berdasarkan hasil penelitian dari 10 siswa kategori Overweight ratarata penurunan cairan tubuh sebesar 730 ml, dengan standar deviasi 115,95 dan standar error 38,65. Dari 10 siswa kategori Normal rata-rata penurunan cairan tubuh sebesar 620 ml, dengan standar deviasi 95,21 dan standar error 31,74. Berdasarkan hasil penelitian tersebut terlihat penurunan cairan tubuh pada kategori siswa Overweight dan kategori siswa Normal SMA 23 Kabupaten Tangerang. Dalam perhitungan selanjutnya diperoleh nilai t- hitung sebesar 2,19 dengan t-tabel 2,09 pada taraf signifikan 5%. Dengan demikian nilai t- hitung > t- tabel yang menunjukkan bahwa hipotesis nihil (H0) ditolak dan hipotesa alternatif (H1) diterima. Maka didapat kesimpulan siswa kategori Overweight lebih banyak mengalami penurunan cairan tubuh dari pada siswa kategori Normal.
